Classification Of Diamond Drill Bits

There are many methods for classifying diamond drill bits. The following are common methods:

First, by purpose

Engineering Drilling is mainly used for engineering construction. This type of engineering drill has many specifications and the largest amount, and has formed a special main product series.

Industrial drills are mainly used for drilling and coring, mainly for the processing of products, such as wide-screen wide-lens blinds, wafer nesting, etc.

Sample drilling is mainly used for sampling analysis of materials, such as analysis of large graphite electrodes and refractory bricks.

Second, according to their manufacturing methods

Hot pressing method is similar to the hot pressing manufacturing process of geological impregnated bits. A ferrule can be made first and then welded to the steel body, or it can be directly pressed onto the steel body.

Electroplating is similar to the process of electroplating drill manufacturing. The electroplating method can be further divided into an epitaxial growth method and a conventional method.

Third, according to the diamond classification used

Natural diamond engineering drills are made of high-quality natural diamonds, which are used in building materials and construction industries.

Synthetic diamond engineering drills are made of high-quality synthetic diamond single crystals, which are mostly used in the optical and chemical industries. China's thin-walled diamond engineering drills/stone cutting drill bits started late, and have not yet developed a national standard. Each diamond drill bit manufacturer provides a specification of products according to the needs of the market.

THE PRINCIPLE AND PROCESS OF PRECISION METAL PARTS

Hardware stamping parts manufacturers must handle five points when processing precision metal parts in order to ensure the accuracy of the stamping parts. 

Five principles for processing precision metal parts

1. The principle of precision

The number of processes for drawing parts is related to the material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, which can be confirmed only after drawing process calculations.

2. The principle of exquisiteness

When the section management and standard precision requirements of stamping parts are high, you can consider adding a trimming process after the punching process or directly choose to use a fine punching process.

3. The principle of finesse

The number of processes for bending parts mainly depends on the complexity of its structure, and metal stamping parts need to be determined according to the number of bending angles, relative orientation, and bending direction.

4. The principle of quality

In order to ensure the quality of precision metal parts and the stability of the processing technology of metal stamping parts, sometimes it is necessary to increase the number of processes, such as additional positioning technology for bent parts, increased deformation in the forming process, reduction of hole punching to transfer deformation areas. It can ensure that each product is refined and exquisite.

5. The principle of precision

Blanking the workpiece with a simple shape can be finished with a single-process die. When processing the metal stamping parts with a messy shape, the surface and the inside summary should be divided into several precision parts for blanking due to the restriction of the structure or strength of the die, which needs to be selected. It shall adopt multiple metal stamping processing procedures. Besides, continuous die can also be selected when necessary.

For workpieces with high flatness requirements, a leveling process can be added after the punching process to accurately adjust the characteristics of each product to the production process.

Stamping processes for processing metal parts

In the metal stamping parts processing plant, the cold stamping process is used to process metal stamping parts. Today, I will help you to understand the more commonly used processes in this stamping process.

1. Blanking process

Blanking is the basic process in the cold stamping process. Through blanking, the required metal stamping parts can be stamped out, and the blanks can be prepared for other cold stamping processes.

2. Bending process

Bending is a plastic forming process to make a flat blank into a workpiece with a certain shape angle and size requirements. The bending process uses different tools and equipment due to the different shapes of the processed metal stamping parts. Bending methods can be divided into press bending, bending, twist bending, roll bending and stretch bending.

3. Deep drawing process

Deep drawing can punch a flat blank of a certain shape into open hollow parts of various shapes through a drawing die, or use the open hollow machined parts as a blank to further change the shape and size of the hollow part through a cold stamping process.

The drawing process of metal stamping parts can be divided into two categories. One is to use a flat plate as a blank, which does not produce large thinning during the drawing process, and the thickness of the cylinder wall and the cylinder bottom are relatively consistent, which is called thinning and deep drawing. This is based on the hollow part with bottom opening as the blank, and the precision metal parts is formed by reducing the wall thickness, which is called thinning and deep drawing.

4. Forming process

The sheet metal forming process is a general term for the process of changing the shape and size of the blank through the local deformation of the sheet metal. Common forming processes include: bulging, flanging, necking, leveling and shaping.

For a metal stamping part, because of its different shape, size and purpose, the stamping process of the metal stamping part is different, and the stamping materials used are also different.

The process designer of the metal stamping parts factory should design and select a reasonable stamping process according to the requirements of the sample parts. While meeting the performance of the stamping parts, it should also be able to maximize the production efficiency.

[steelbuildings2017]

PRINCIPLES AND BENEFITS OF STAMPING PARTS

What are the 5 design principles of metal stamping parts?

For the quality of stamping parts, stamping die occupies a very important factor. The quality of the stamping die and the early design of the die are the key factors affecting the quality of the die. And what should be paid attention to in die design?

1. The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing material consumption as much as possible. Where possible, low-cost materials should be used to manufacture precision parts to achieve no waste and less waste blanking.

2. The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.

3. The design of stamping parts must be simple in shape and reasonable in structure, so as to simplify the structure of custom metal stamping die and simplify the number of processes.

That is to say, a small number of simple stamping processes are used to complete the processing of the entire cnc parts, and the use of other processing methods is reduced, which is conducive to stamping operations, facilitates the organization of mechanized and automated production, and improves labor productivity.

4. Existing equipment, process equipment and process flow should be used to process it and prolong the service life of the mold.

5. Under normal conditions of use, the design of metal stamping products should have as low as possible the requirements for size, precision and surface roughness, which is conducive to the exchange of products, reduces waste, and ensures the stability of stamping product quality.

What are the benefits of stamping parts processing?

Compared with castings and forgings, stampings are thin, uniform, light and strong. Stamping can improve the rigidity of the ribs, undulations or flanges of the workpiece, which are difficult to manufacture by other methods.

Due to the use of precision molds, the precision of the stamping parts can reach micron level, the repeatability is high, and the specifications are the same. The surface and internal properties of sheet metal for stamping have a great influence on the quality of stamped products!

Whether the stamping technology meets the standards, whether the quality can be guaranteed, whether the materials and purchased metal parts are available, whether the equipment is original or new, whether the current production capacity and manpower of the manufacturer are sufficient, all of which are the points you should consider to decide whether to choose the manufacturer for production and processing of stamping parts.

Now there are many stamping parts manufacturers in China, so many people will shop around and choose cheaper manufacturers for processing. However, blindly choosing a manufacturer with a relatively low price for processing will have hidden dangers.

If the price of stamping processing is too low, it must be considered whether the quality of the stamped parts can be guaranteed, or whether the stamping parts have other defects and so on.

Introduction to Spider Wasp

A. asiaticus of spider wasp

A. asiaticus may refer to:

An abbreviation of a species name. In binomial nomenclature the name of a species is always the name of the genus to which the species belongs, followed by the species name (also called the species epithet). In A. asiaticus the genus name has been abbreviated to A. and the species has been spelled out in full. In a document that uses this abbreviation it should always be clear from the context which genus name has been abbreviated.

Some of the most common uses of A. asiaticus are:

Acartauchenius asiaticus, a money spider species in the genus Acartauchenius

Aduncothrips asiaticus, a thrip species in the genus Aduncothrips

Aesalus asiaticus, a beetle species in the genus Aesalus

Alastor asiaticus, a wasp species in the genus Alastor

Araneus asiaticus, an orb-weaver spider species

Archaeornithomimus asiaticus, a dinosaur species

Asiabadus asiaticus, a ground spider species in the genus Asiabadus

Asprella asiaticus, a snail species in the genus Asprella

------

Mesosoma of spider wasp

The mesosoma is the middle part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the metasoma. It bears the legs, and, in the case of winged insects, the wings.

In hymenopterans of the suborder Apocrita (wasps, bees and ants), it consists of the three thoracic segments and the first abdominal segment (the propodeum). For historical reasons, in ants it is commonly referred to by the alternative name alitrunk.

In scorpions, it is composed of six segments and forms the first part of the abdomen, containing all of the major organs. The first segment contains the sexual organs as well as a pair of vestigial and modified appendages forming a structure called the genital operculum. The second segment bears a pair of featherlike sensory organs known as the pectines; the final four segments each contain a pair of book lungs. The mesosoma is armoured with chitinous plates, on the upper surface by the tergites and on the lower surface by the sternites.

In other arachnids such as spiders, the mesosoma is fused with the metasoma to form the opisthosoma.

Wytham Woods of spider wasp

Wytham Woods is a 423.8-hectare (1,047-acre) biological Site of Special Scientific Interest north-west of Oxford in Oxfordshire. It is a Nature Conservation Review site.

Habitats in this site, which formerly belonged to Abingdon Abbey, include ancient woodland and limestone grassland. Over 500 species of vascular plant have been recorded, and more data about the bird, mammal and invertebrate fauna, have probably been recorded about this site than any other in the country as a result of studies by Oxford University. More than 900 species of beetles, 580 of flies, 200 of spiders, 700 of bees, wasps and ant, 250 of true bugs and 27 of earthworms have been recorded.

Access is only allowed with a permit from the owner, Oxford University.

Irenangelus of spider wasp

Ireangelus is a genus of kleptoparasitic spider wasps from the sub-family Ceropalinae of the family Pompilidae. The genus has a pan tropical distribution,being known from Oriental, Neotropical, Australian, eastern Palearctic, and Madagascan Zoogeographic regions being best represented in the Neotropics. Irenangelus is closely related to the more widespread genus Ceropales, the two genera forming a monophyletic subfamily, Ceropalinae within the Pompilidae. This is regarded as the most basal grouping of the Pompilidae but this view is problematic because of the kleptoparasitic life history of the Ceropalines, it is now considered that they Ceropalines and other pompilids evolved from a common ectoparasitoid ancestor.

------

Priocnemis perturbator of spider wasp

Priocnemis perturbator is a relatively large species of spider wasp which is quite common in Europe. It was previously considered to be the same species as the closely related P. susterai which were lumped as P. fuscus and this means that some early observations of behaviour are not applicable to either species. Even now the two species need close observation under a microscope or hand lens to distinguish them from each other.

Behavior of spider wasp

Megarhyssa nortoni is a predatory insect. Its larvae are parasitoids of horntail wasp larvae in coniferous trees. The adult female hunts horntail larvae for egg placement. It smells wood-eating fungus, utilized by the horntail larvae to predigest wood pulp, and uses its antennae to detect vibrations made by the horntail larvae. The female M. nortoni curls its ovipositor over its abdomen to insert the tip of the ovipositor at a right angle into the bark and cuts into the tree until it reaches the horntail larval tunnel. The female then deposits a very slender egg through its ovipositor into the tunnel on or near the horntail larva. The M. nortoni larva then hatches to eat the live horntail larval host from the inside causing the horntail larva's eventual death. The M. nortoni larva pupates inside its host and emerges the following summer as an adult.

Although imposing, the female M. nortoni does not sting and is harmless to humans. Adult M. nortoni feed on nectar and water.

------

Dipogon of spider wasp

Dipogon is a genus of spider wasps of the family Pompilidae in the subfamily Pepsinae. They are found in Europe, Asia, and North America. Their generic name ("two beards") comes from the characteristic long bristle tufts just below the mandibles, which are used to carry material to construct the cells in the nest, and for constructing the nest.

Species in Dipogon include:

------

Tastiotenia festiva of spider wasp

Tastiotenia festiva is a species of spider wasp in the subfamily Pompilinae. It was first described by its discoverer, Howard Ensign Evans, in 1950. It is a rather small spider wasp species, growing from 36.

5 mm in length and has only been observed rarely. It lives in the desert regions of the south-western United States (southern California to western Texas) as well as northern Mexico (Sonora and Baja California). Based on Evans' biological observation in 1961, it is assumed that Tastiotenia festiva consumes black widow spiders as part of its diet and that it utilizes burrows made by other wasps for nesting.

Thalassianthus aster of spider wasp

Thalassianthus aster is a species of sea anemone in the family Thalassianthidae. It dwells in a number of habitats, even existing symbiotically on top of other motile invertebrates such as hermit crabs in a relationship similar to the pom pom crab. Its nematocysts contain a Type-II Na-channel toxin known as -TLTX-Ta1a according to the currently developing systematic nomenclature for peptide and protein toxins from sea anemones.

Biota of spider wasp

It seems no detailed survey has been done of the lake. As cattle often walk in the lake it is likely to be polluted. In the 1970s the dunes between the lake and the harbour were sown with tree lupin (Lupinus arboreus) and Marram Grass, which has reduced sand movement and provided a low quality pasture. Frogs can be heard croaking in the lake. The pompilid wasp (Cryptocheilus australis) and its prey, the nursery web spider (Dolomedes minor), have been seen near the lake

------

Biology of spider wasp

Adults of T. unicolor feed at honeydew secretions and flowers. Females have been captured at honeydew from galls of Disholcapsis eldoradensis on Quercus lobata and at flowers of Asclepias erosa, Baccharis sarothroides, Chrysothamnus sp., Lepidospartum squamatum, and Wislizenia refracta. Males have been taken on the flowers of Calochortus catalinae, Hemizonia fasciculata, Rhamnus californica, and Xanthium spinosum. Both males and females visit the extrafloral nectaries of Helianthus and have been collected at flowers of Atriplex semibaccata, Cicuta sp., Eriogonum fasciculatum, Eriogonum gracile, and Foeniculum vulgare. The flight period in California is from May to October, with a peak in July and August.

Anatrachyntis terminella is a moth in the family Cosmopterigidae. It was described by Francis Walker in 1864 and is known from Australia (including New South Wales) and Fiji.

The wingspan is about 8mm. The forewings are patterned and hindwings have trailing hairy fringes.

The larvae have been recorded in deserted nests of wasps of the genus Polistes, galls on flower buds of Acacia binervata, egg sacs of the spider Trichonephila edulis as well as dead insects and dead leaves.

Geology of spider wasp

Brown clay underlies the dunes, which limits the rate of seepage through the dunes, thus forming lakes where dune advance has blocked valleys. The lake bed and stream are on Awhitu sands. They are about a million years old and made up of pumiceous cross bedded brown and yellow clayey sands. The lake is dammed by dunes of Nukumiti Sands which have formed in the last 800 years.

Scelioninae of spider wasp

Scelioninae is a subfamily of wasps in the family Platygastridae. It is a very large cosmopolitan group (over 3000 described species in some 160 genera) of exclusively parasitoid wasps, mostly small (0.510mm), often black, often highly sculptured, with (typically) elbowed antennae that have a 9- or 10-segmented flagellum. It was formerly considered to be a family Scelionidae but has been reclassified as a subfamily of the Platygastridae.

The subfamilies Scelioninae, Teleasinae, and Telenominae were formerly in the family Scelionidae, but Scelionidae was combined with the family Platygastridae because of genetic similarities. The name Platygastridae was retained for the resulting family because of seniority.

What impacts caused by heat when the mechanical seal is used?

What impacts caused by heat when the mechanical seal is used?

The mechanical seal is in the process of use, and if the usage time is very easy to use, the use of overheated is used, in this, the next impact of the equipment uses overheated effects in order to better use the device.

According to the nature of working conditions and media, there is a high temperature resistance, low-temperature seal, high pressure, corrosion-resistant seal, particulate medium seal, and seal of light hydrocarbon media that can be adapted to vaporization, according to different use Select the seal of different structures and materials.

In one or two end faces, a gap appears. This phenomenon illustrates that the distance from the two end faces is too large, and when the two end faces are tightened, the gap is generated. A common cause of end-faced separation is that the inlet seal medium is evaporated. For example, water, particularly in a hot water system or a liquid-containing liquid, and the water is expanded, thereby separating the two ends. The pump of the pump, the occlusion of the seal may also be the cause of the gap of the sealing end surface. In this case, it is not caused by the vibration and coupling because this is not enough to cause the end surface to create a gap.

Reducing the end surface temperature is a common method of preventing a sharp evaporation of the medium. At the same time, it is also advantageous to use a material group with a thermal conductive, such as a nickel-based rigid alloy and a bronze graphite group, in addition, a balanced mechanical seal is used, or a special corrosion-resistant seal is compressed from the external solution cooling. Or directly cool the seal within the cavity, etc., which is very effective for reducing the temperature of the sealing end.

Failure seals, friction sub-ends often leave a fine radial crack, or radial cracks and water bubbles, and even cracking. This is due to the sealing overheating, especially ceramics, and hard allocation seals easily produce such injuries. The medium lubricity is poor, overload, high line speed, high line velocity, and improper matching material, any of these factors, or the superposition of several factors, can produce excessive friction fever, if frictionless can not be distributed in time, It produces a dyeing and complete mechanical sealing thermal crack, thereby excessive wear and high leakage.

To solve the seal overheating problem, in addition to changing the end surface area, reduce the load, can also use a stationary seal and a streamway to strong cooling circulating fluid guiding sealing surface, or a fluid power groove on the sealing end surface is resolved. There are many fine hot spots and isolated color chances on the friction end surface, which means that the seal is distorted under high pressure and heat. For the heat deformation of the end face, the general calculation method is not allowed, and the finite element method should be used to improve the design of the seal ring.

Pump mechanical seal repair

Pump mechanical seal repair

 The mechanical seal of the pump refers to an apparatus mounted to function in a dynamic seal in a pump apparatus to avoid a component of the water pump through the pump shaft through the pump shaft. However, it is inevitable that there will be fault conditions during use, so it is important to master the corresponding maintenance method.

(L) the seal of the shaft sleeve and the shaft;

(2) Sealing between the articles and the bushing;

(3) Moving, static ring seal;

(4) Sealing of the static ring and the static ring;

(5) Sealed end cap and the seal between the pump body.

In general, the leakage between the shaft extensions, the sealing end cap and the pump body is relatively easy to discover and solve, but it is necessary to observe, especially when the working medium is liquefied gas or high pressure, toxic and harmful gas, relatively difficult some. It is difficult to disclaimer and judging the remaining leaks, and must be observed, analyzed and developed by long-term management and maintenance practice.

In summary, in order to better extend the efficiency of the mechanical seal of the pump, we need our regular maintenance work, reduce unnecessary losses, and effectively extend its service life.

Mechanical seal selection method and principle

Mechanical seal selection method and principle

The mechanical seal belongs to one of the more complex mechanical infrastructure components, and is a key component of various mechanical seal pumps, reaction synthesis, turbine compressors, submersible motors and other equipment. Its sealing performance and service life depends on many factors, such as selection, so that the method and principles of its selection will be introduced.

I. Selection method

The mechanical seal is different from the working conditions and medium properties, high temperature resistance, low-temperature mechanical sealing, high pressure, corrosion resistant mechanical seal, particulate medium mechanical sealing, and mechanical sealing of a light hydrocarbon medium adapting to vaporization, etc., according to different The use of different structural types and materials mechanical seals are selected.

The main parameters of the selection are: sealed cavity pressure (MPa), fluid temperature (° C), operating speed (m / s), fluid mechanical sealing characteristics, and effective space of mounting sealing.

The basic principles of selection are:

 1. Determining the sealing structure is determined using a balanced or non-equilibrium, single-end surface or double end face or the like according to the sealing cavity pressure.

 2. Depending on the operating speed, it is determined using a rotary or static, fluid dynamic pressure or non-contact type.

3. Determine the friction pair and auxiliary sealing material according to temperature and fluid properties, and correctly select lubrication, rinsing, heat preservation, cooling and other mechanical sealing circulation protection systems.

4. Determining a multi-spring or single spring or a wave spring, an inner or outer shape according to the effective space of the installation seal.

In summary, the selection of mechanical seals according to the above methods can better ensure the use of equipment and the extension of related performance, extend the use, and reduce damage.
