Besides the familiar advantages such as robustness, stiffness and zero backlash, the electromechanical drives have even more positive aspects. The noise level for the operator and maintenance personal is considerably reduced by eliminating the hydraulics power pack. Additionally the energy consumption in series operations is reduced by up to 30 percent for the rolled profiles. Finally the new HP drive concept provides higher thermal machine stability that leads to increased profile precision and size stability rolled parts. For many applications, thread rolling, is the best choice for creating higher quality external threads in a single pass due to it’s chipless operation. As we’ve seen, a thread roller opens automatically at a calculated point in its stroke. Automatic closing can usually be done within the normal cycle of the machine.

Whether you’re ordering from our extensive in-stock inventory, or requesting custom-made materials, the thread rolls you get from CJWinter arrive quickly, perform at your exact specs, and last a long, long time. Static tensile tests on parts formed through thread rolling show overall increases in strength of about 30 percent. For more than 60 years, Superior is your thread rolling and manufacturing supplier of choice. Superior Thread Rolling Company has been providing quality thread rolling services since 1951. While in this position, let’s do what I call a “quick check” for alignment. If we have good alignment, all three rolls will contact the blank diameter at about the same time. By rotating the rolls, try to find the first and last roll that makes contact. It’s important to understand that where the rolls are set produces the thread’s root diameter and the flank angles. The flank angles, in turn, will mathematically provide the thread’s pitch diameter.

The smallest lead screw tapper from many suppliers is for the 0-80 TPI range, but the Milman T was designed to tap all of the UNM sizes. Milman Engineering (Rochester, Wash.) no longer makes these machines because of the lack of demand, but the company supplies repair parts for the 500 machines in use. The GS TEM-Mini grinder can produce M0.5 × 0.125 pitch threads on hardened high speed steel to make forming taps. Cast threads in metal parts may be finished by machining, or may be left in the as-cast state. (The same can be said of cast gear teeth.) Whether or not to bother with the additional expense of a machining operation depends on the application. For parts where the extra precision and surface finish is not strictly necessary, the machining is forgone in order to achieve a lower cost. With sand casting parts this means a rather rough finish; but with molded plastic or die-cast metal, the threads can be very nice indeed straight from the mold or die.

Undercut–Undercut or not, the same pre-roll chamfer recommendations should be followed. An undercut is not necessary for the rolling operation, as long as the thread runout can be accommodated by the mating part. If the part has an undercut, the starting diameter of the chamfer angle must be less than the minor diameter of the final thread, or the rolls will leave marks in this area. A shorter progression can be used to allow threading up closer to a shoulder, but roll life will be adversely affected. About the closest that an axial system can thread to a shoulder is 11/2 times pitch, which equates to a 0.6K lead. Because of the skew angle, both sides of the rolls can be used. The skew angle also produces a forward motion, making the roller head self-feeding and self-opening.

A common example of molded plastic threads is on soda bottles. A common example of die-cast threads is on cable glands (connectors/fittings). Rarely, thread cutting or grinding will be followed by thread lapping in order to achieve the highest precision and surface finish achievable. This is a toolroom practice when the highest precision is required, rarely employed except for the leadscrews or ballscrews of high-end machine tools. Another variant of form-milling involves holding the cutter’s axis orthogonally (no canting to the thread’s helix angle) and feeding the cutter in a toolpath that will generate the thread. The part is usually a stationary workpiece, such as a boss on a valve body or a hole in a plate or block . This type of thread milling uses essentially the same concept as contouring with an endmill or ball-nose mill, but the cutter and toolpath are arranged specifically to define the “contour” of a thread. The cutter geometry reflects the thread pitch but not its lead; the lead is determined by the toolpath. Superior Thread Rolling offers more than just thread rolling services in Southern California.

Superior Thread Rolling offers precision CNC machining services with a quick turn-around for high or low volume orders in the Southern California region. Roll shafts, materials and bearings used in production are European quality. NC playback and CNC graphic control systems are available as optional accessory. In comparison with linear guideways with rollers, box guideways have a significantly larger bearing face between the two mounted carriages and the machine bed. This extends the life of tools, and helps them run more smoothly, resulting in better-quality surfaces on the workpiece and better cutting performance. The greater surface area also means that significantly heavier workpieces can be mounted and moved. Additional advantages of box guideways are their extreme durability and low sensitivity to collision damage (“crash situations”).

When the material freezes in the mold, it retains the shape after the mold is removed. The material is heated to a liquid, or mixed with a liquid that will either dry or cure . Alternately, the material may be forced into a mold as a powder and compressed into a solid, as with graphite. In one variant of form-milling, the single-form cutter is tilted to the helix angle of the thread and then fed radially into the blank. The blank is then slowly rotated as the cutter is precisely moved along the axis of the blank, which cuts the thread into the blank. This can be done in one pass, if the cutter is fed to the full thread depth, or in two passes, with the first not being to the full thread depth.

The longer the thread to be cut, the greater the potential for deflection and chatter, resulting in shorter tool life. However, the dimensions of thread rolling dies do change with use. The stress builds up to a point where the hardened material of the die just fatigues and breaks away in small pieces at the crest where the die is doing the most work. Upto this point, the dies will make the same profile every time. Practically no adjustments are needed throughout the life of the rolls, which is typically tens of thousands of parts per set. The workpiece material is stressed beyond its yield point, which causes it to flow and conform to the mirror image of the die’s profile – refer to figure 1. In general CNC turning, threads are produced by using a single-point insert, taking numerous passes at decreasing depths of cut or by thread rolling using a LMT-Fette-style head and three hardened steel rolls. Single-point threading for internal and external threads can thread workpieces up the capacity of the lathe diameter of stock handled, whether bar or chucking machine.

Thread Rolling Inc. uses a variety of machine types and sizes to roll threads. As a guide, coarse pitches and high tensile materials are rolled at the lower end of the above speed ranges. Fine pitches and light alloys may be rolled at the top end of the above speed ranges. 1.spindle is powered by two servo motors,can be indinitely adjustable-speed,to realize the forward reset when rolling products. As a part of the Roll On Roll Off system, Turning Concepts has developed process sheets that are provided along with the system that technically defines the set-up and CNC programing required. With access to the library of process sheets developed by Turning Concepts when using the Roll On Roll Off system, any brand of CNC machine tool can be utilized. Turning Concepts has developed the Roll On Roll Off system for axial thread rolling on CNC applications.
