Fastener thread processing method, including internal and external threads

Thread processing is a process that uses tools to make threads and uses cutting, turning, milling, grinding and other processes to process workpieces. Generally, it refers to the method of processing threads on the workpiece with shaped tools or abrasive tools. There are mainly the following methods of fastener thread processing:

1. Thread cutting

Generally refers to the method of machining threads on a workpiece with a forming tool or an abrasive tool, which mainly includes turning, milling, tapping, threading grinding, grinding, and whirlwind cutting. When turning, milling and grinding threads, the transmission chain of the machine tool ensures that the turning tool, milling cutter or grinding wheel moves along the axis of the workpiece accurately and uniformly for each revolution of the workpiece.

When tapping or threading, the tool (tap or die) rotates relative to the workpiece, and the first formed thread groove guides the tool (or workpiece) to move axially.

2. Thread turning

For turning threads on a lathe, a forming turning tool or a thread comb tool can be used. Turning threads with a forming turning tool is a common method for single-piece and small batch production of threaded workpieces due to the simple tool structure; turning threads with a thread comb has high production efficiency, but the tool structure is complex, which is only suitable for medium and mass production. Turning fine-tooth short-threaded workpieces.

The pitch accuracy of the trapezoidal thread turning on an ordinary lathe can generally only reach 8-9 (JB2886-81, the same below); when threading on a specialized threading lathe, the productivity or accuracy can be significantly improved.

3. Thread milling

Milling is performed on a thread milling machine with a disk milling cutter or a comb milling cutter. Disc-shaped milling cutters are mainly used for milling trapezoidal external threads on screw, worm and other workpieces. The comb milling cutter is used for milling internal and external common threads and taper threads. Since it is milled with a multi-edge milling cutter, the length of its working part is greater than the length of the thread being machined, so the workpiece can be machined only by rotating 1.25 to 1.5 revolutions Finished, the productivity is high.

The pitch accuracy of thread milling can generally reach 8 to 9, and the surface roughness is R5 to 0.63 microns. This method is suitable for mass production of general precision threaded workpieces or rough machining before grinding.

4. Thread grinding

It is mainly used for processing precision threads of hardened workpieces on thread grinders. According to the different cross-sectional shapes of the grinding wheels, there are two types of single-line grinding wheels and multi-line grinding wheels. The pitch accuracy that can be achieved by single-line grinding wheel grinding is 5 to 6, and the surface roughness is R1.25 to 0.08 microns, and the grinding wheel dressing is more convenient. This method is suitable for grinding precision lead screws, thread gauges, worms, small batches of threaded workpieces and relieving precision hobs.

Multi-line grinding wheel grinding is divided into two types: longitudinal grinding method and plunge grinding method. The width of the grinding wheel of the longitudinal grinding method is smaller than the length of the thread to be ground, and the thread can be ground to the final size by moving the grinding wheel one or several strokes in the longitudinal direction. The width of the grinding wheel of the plunge grinding method is greater than the length of the thread to be ground. The grinding wheel cuts into the surface of the workpiece radially, and the workpiece can be ground after about 1.25 revolutions. The productivity is higher, but the accuracy is slightly lower, and the dressing of the grinding wheel is more complicated. The plunge grinding method is suitable for relieving large batches of taps and grinding certain fastening threads.

5. Thread grinding

Use softer materials such as cast iron to make nut-type or screw-type thread grinds, and perform forward and reverse rotation grinding on the parts of the machined threads with pitch errors on the workpiece to improve the pitch accuracy. Hardened internal threads are usually ground to eliminate deformation and improve accuracy.

6. Tapping and threading

Tapping is to use a certain torque to screw the tap into the pre-drilled bottom hole on the workpiece to process the internal thread.

Threading is to use a die to cut an external thread on a bar (or tube) workpiece. The processing accuracy of tapping or threading depends on the accuracy of the tap or die. Although there are many methods for processing internal and external threads, small diameter internal threads can only be processed by taps. Tapping and threading can be operated manually, or lathes, drilling machines, tapping machines and threading machines can also be used.

7. Thread rolling

The processing method of plastically deforming the workpiece with a forming rolling die to obtain a thread. Thread rolling is generally performed on a thread rolling machine or an automatic lathe with an automatic opening and closing thread rolling head. It is suitable for mass production standards. External threads of fasteners and other threaded couplings.

Thread Mills for Pipe Threading: Common Terms

The following terms and designations are fundamental to understanding thread type, form, and more. The following terms and designations are fundamental to understanding thread type, form, and more. 

● Class of thread:  An alphanumerical designation indicating a thread’s grade of tolerance or allowance. Common thread classes are categorized under Metric, NPT, UN, and ACME designations.

● Crest:  The portion of the thread which joins the flanks of the thread; the “highest” portion, furthest away from the cylinder. 

● Flank:  One of two surfaces connecting the crest with the root at the base of the thread. 

● Helix angle: The angle between a thread’s helix and a line parallel to the axis of rotation.

● Major diameter:  Diameter of the major cylinder, for straight threads. The distance from one thread’s crest to the corresponding thread’s crest on the other side, traveling perpendicular to the axis of rotation.

● Minor diameter:  The diameter of the minor cylinder, for straight threads. The distance from one thread’s root to the corresponding root on the other side, traveling perpendicular to the axis of rotation.

● Pitch:  Distance between corresponding points on threads, taken parallel to the thread axis; for instance, crest to crest, parallel to the thread axis, gives a pitch measurement. 

● Root:  The surface of the thread which is adjacent to the cylinder or cone from which the thread rises.

● Thread angle:  The angle between the thread flanks. For instance, NPT threads have a 60° thread angle. Thread Types 

There are many standard thread types, among the following: 

● ACME:  ACME threads were developed in the late 1800s to replace square threads and feature a trapezoidal thread form, with a “flat” crest. They are strong, easy to manufacture, and often used for lead screws.

● American Pipe Threads (NPT, NPTF):  National Pipe Tapered Threads or National Pipe Tapered for Fuels, both with a 60° thread angle. These require thread sealant for a leakproof seal.

● BSPP:  British Standard Pipe Parallel Thread, with a thread flank angle of 55°.

● BSPT:  British Standard Pipe Taper Thread, also with a thread flank angle of 55°.

● UN:  Unified National Threads, commonly used screw, nut, and bolt threads in the United States and Canada. They have a flank angle of 60°.

Where Can You Get High-Quality Thread Mills for Pipe Threading? Thread mills for pipe threading represent a significant improvement over cutting threads with a tap and die. 

Thread milling is superior for cutting threads on exotic materials, softer non-ferrous alloys, and materials with thin walls. Thread milling uses mills that are more stable, have fewer limitations, and offer superior chip evacuation.

What is SCREW JACK?

Screw jacks are mechanical transmission equipment used in various industrial applications to convert rotational motion into linear motion. Screw jacks can be u sed to lift any load, pull or push mechanical equipment, and modify tight clearances between mechanical elements. Polimak's screw jacks have a mechanical capacity of 5kN to 2000kN. Depending on the type of motion, screw jacks can be utilized as linear motors, linear actuators, or mechanical lifts.

Screw jacks include four main components, a trapezoidal lifting screw, a worm screw, a worm gear, and a gear housing. The screw in the worm gear goes upwards or downwards linearly as the worm gear rotates. Worm screw rotation can operate manually or with the help of a motor.  They ensure linear motion solutions with precise positioning and smooth operation. The screw feed rate is determined by the turning speed, the number of gear teeth, and the screw pitch size.

Translating screw jacks, travelling screw jacks and mechanical screw jacks are the three primary varieties of screw jacks manufactured by Polimak. The lead screw does not move up and down in some screw jack models. It does nothing but revolve around its axis. The screw is moved along by a lifting nut (also known as a travelling nut). To reduce friction, the screw jack's lifting nut is composed of bronze.

What is a lead screw?

Sometimes known as a translating screw or power screw, a lead screw is simply a screw linkage in a machine used to translate rotating motion into linear motion. It is a common part of linear actuators.

What is a mechanical screw jack? A mechanical lifting and pulling screw jack is one used to lift heavy loads and assemble larger structures by pulling. Mechanical screw jacks are widely used in industrial plants, machinery assembly and other applications.

How does a translating screw jack? The lead screw in translating screw jack moves up and down through the gear housing. As the worm gear rotates, it directly acts on the lead screw and the lead screw translates linearly. The inclination of the lead screw to turn together with the worm gear increases as the lifting load on the screw jack increases.

How does a travelling nut screw jack work? A travelling nut screw jack is commonly known as a rotating screw jack. It is configured in such a way that the lead screw is fixed to the worm gear. A nut is attached to or placed on the lead screw. Rotation of the worm gear gives rise to the rotation of the lead screw, thereby causing the attached nut to translate along the lead screw.

Trapezoidal thread taps – Basic information

Precise dimension is one of the most vital stipulations of any sort of engineering job. The perfect way of measurement is via a Trapezoidal thread gauge.

Tap in the form of Trapezoidal thread tap is a type of screw thread application that has Trapezoidal externally. They’re one of the most commonly utilized in producing power screws and lead screws. The advantages of these taps include convenience of developing extremely high power.

They’re mainly required at place where massive loads are needed to come in action such as lead screw of the lathe or in matter of combined making associate.

In addition, they’re also utilized in devices that are expected for extreme translational pace.

Trapezoidal thread taps have standard modifications such as left side threads, now start threads and self-centered threads.

ACME thread seen as the genuine and first any build Trapezoidal thread, although with a small difference and it remains one of the most commonly utilized tap in all worlds. The ACME thread gauge is found in one of the most important engineering works where the defects can only not be condoned, and carelessness would outcome in nothing but big loses of properties and lives. The instance is rockets, aircraft and bullet trains.

ACME threads have lots of advantages over several other threads such as cube threads. Cutting process can be completed simply utilizing one spot thread taps and die. It also has superior wear connected to the cube or square thread because it permits the compensation of wears. In potential, it’s seen as the finest thread tap. It permits the nuts to connect smoothly and perfect into point on the leader’s screw.

One more type of renowned quadrangle is that the metric that is similar to the ACME with single exception being in angles. It as an angle of thirty degrees while ACME has the angle among threads of twenty-nine degree, Metric threads types are more widely utilized for triangular thread forms. Though, the ACME is the largely utilized Trapezoidal thread type.

Cube threads were actually the first option of flooding heavy loads, but there was a large obstacle to be produced. It was fine and extremely efficient for unwanted aims such as extreme load transfer. And the cause behind their extreme output was the ninety-degree angle.

But altering the angle of twenty-nine degrees in case of ACME taps, the base could be extended widely and not just it demonstrated to be a lot stronger but it’d also bear a very huge weight.

Best lead screw nut manufacturers online in india

A leadscrew (or lead screw), otherwise called a force screw or interpretation screw, is a screw utilized as a linkage in a machine, to make an interpretation of transforming movement into direct movement. Due to the huge region of sliding contact between their male and female individuals, screw strings have bigger frictional vitality misfortunes contrasted with different linkages. They are not ordinarily used to convey high force, yet more for irregular use in low force actuator and positioner systems. Leadscrews are generally utilized in straight actuators, machine slides, (for example, in machine devices), tight clamps, presses, and jacks. Leadscrews are a typical segment in electric direct actuators. 

Lead fastens are frequently utilized instrument grade applications where smooth, exact, clean, and upkeep free activity is required. The nut material is ordinarily made of an inside greased up polymer. A few models would be research center and life sciences hardware, for example, DNA examining, checking and liquid dealing with gadgets. Different applications incorporate etching, fast prototyping, review, and information stockpiling. Lead fastens are additionally utilized hard work applications when joined with a metallic (regularly bronze) nut. 

Best lead screw nut manufacturers online in India - Igus

Leadscrews are fabricated similarly as other string structures (they might be moved, cut, or ground). 

A lead screw is some of the time utilized with a split nut likewise called half nut which permits the nut to be separated from the strings and moved pivotally, autonomously of the screw's turn, when required, (for example, in single-point stringing on a manual machine). A split nut can likewise be utilized to make up for wear by compacting the pieces of the nut. 

A hydrostatic leadscrew defeats a large number of the hindrances of a typical leadscrew, having high positional exactness, low rubbing, and low wear, yet requires constant flexibly of high weight liquid and high accuracy produce prompting altogether more prominent expense than most other straight movement linkages.

Force screws are ordered by the geometry of their string. V-strings are less appropriate for leadscrews than others, for example, Acme since they have more rubbing between the strings. Their strings are intended to prompt this rubbing to shield the latch from extricating. Leadscrews, then again, are intended to limit friction.Therefore, in general business and modern use, V-strings are kept away from for leadscrew use. By the by, V-strings are here and there effectively utilized as leadscrews, for instance on micro lathes and micromills.

Favorable circumstances and detriments 

Leadscrews are utilized to raise and lower the front entryway of the Boeing 747-8F Freighter airplane. 

The benefits of a leadscrew are:

Huge burden conveying ability 

Minimized 

Easy to plan 

Simple to make; no specific apparatus is required 

Enormous mechanical bit of leeway 

Exact and precise direct movement 

Smooth, calm, and low support 

Negligible number of parts 

Most are self-locking 

The drawbacks are that most are not extremely productive. Because of the low productivity they can't be utilized in constant force transmission applications. They likewise have a serious extent of grating on the strings, which can destroy the strings rapidly. For square strings, the nut must be supplanted; for trapezoidal strings, a split nut might be utilized to make up for the wear.[5] 

Options 

Options in contrast to activation by leadscrew include: 

Ball screws and roller screws (at times arranged as kinds of leadscrew instead of in contradistinction) 

Liquid force (i.e., power through pressure and pneumatics) 

Apparatus trains (e.g., worm drives, rack-and-pinion drives) 

Electromagnetic incitation (e.g., solenoids) 

Piezoelectric incitation
