The system can be designed according to the actual production of the customer. Help solve the problem of picking up embryos from Input conveyor to machine. Thread rolling is a process that has been around for more than one hundred years and there are machines in service that make the fifty-year old ones look young by comparison. Thread rollers come in a variety of types and sizes, but they all use a mechanism where hardened steel dies are matched and set to penetrate with force in order to reshape the material surface of a round diameter into a thread form. A cylindrical work piece or blank is fed into the machine and the dies rotate or reciprocate in order to produce threads in a “chipless” forming process. Every thread form, shape, and size has a unique set of dies which are typically ground from heat treated tool steel (typically Rockwell C 58-62) and procured, rather than made in-house. Distributor of finishing machinery including thread rolling machinery for textile industry.

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”).

I’m not an engineer, nor have I ever looked into it, but my guess is that the thread will be stronger than a cut one.

Tabco’s Mr. Boudreau uses Habegger thread roll dies from Switzerland in his screw machines for rolling threads. They are available from Alouette Tool Co. in adjustable sizes from 0.6 mm and larger. Nonadjustable thread roll dies are available from 0.35 mm and larger. J.I. Morris Company (Southbridge, Mass.) is a large manufacturer of miniature screws and a supplier of taps and gages. The company’s gages range from to the larger sizes, and its taps include plug, bottoming, taper and gun taps. Morris is one of the few suppliers that have gages for these threads. Alouette Tool Co.(Fairport, N.Y.) also provides taps, button dies, threading tools and gages. The process languished until 1867, when Harvey J. Harwood of Utica, New York filed a patent for the cold-rolling of threads on wood screws. Further efforts to cold-roll threads on screws followed, but none seemed to meet with much success until Hayward Augustus Harvey ( ) of Orange, N.J.

CNC Thread Rolling Machine

Run on CNC based control panel, it is highly appreciated for having user friendly nature with long service life and low maintenance requirements. This machine is used for creating threaded profile on workpiece which is used for fastening into mating sections. It has ability to easily & efficiently create threads on both internal & external surfaces of workpieces as desired. Thread Milling Machine offered by us easily gives flexibility of adjusting thread size & profile as per requirement with high speed processing. It is greatly admired for having low operational noise & vibration with easy tool change. Thread blank diameter is very important for correct rolled threads. A 2.4-micron (0.0001 inch) increase in blank diameter increases thread form by 10.1 microns (0.0004 inch). Both thread form and size can be varied by varying part blank size and spindle speed and by adjusting thread rolls.

UNF-3A thread has a pitch diameter of .2268-.2243 and a major diameter of .2500-.2435. The blank size prior to roll threading will be near the maximum pitch diameter and the material displaced by the dies will form up to fall within the major diameter tolerance. On the other end of the spectrum, there is the very specialized niche of high precision thread rolling, primarily on small batches of parts. Some high technology industries, including aerospace and motorsports, require extremely tight tolerance threads with super surface finishes, and the extra strength inherent in parts made with the forming process. Thread Rolling Inc. uses a combination of vertical cylindrical three-die machines, horizontal flat die reciprocating machines, and horizontal cylindrical two-die machines to produce precision threads. Micro screws are commonly produced on automatic screw machines. The threads can be cut with v-groove tools such as with conventional threads, with thread chasers (disc-like holders with three or more mini cutting points), with button thread dies, or with thread rolling tools. Automatic loading unloading (work-piece feeding) system for thread rolling machine is similar to automatic work-piece feeding system for lathe and automatic work-piece feeding system for other machine tools.

For many CNC applications, thread rolling, is the best choice for creating higher quality external threads in a single pass, Chipless operation. The programmer will calculate the actual G97 speed from the recommended constant surface speed. When the running the machine, the control will monitor the actual speed and axis movement. If the machine is fitted with manual override on the spindle speed, the operator must ensure that this is set at 100%. If this setting is changed, the control will accelerate the spindle for the actual threading pass. However, the actual pitch position will probably not match, ensuring that the thread will not “pitch in.” Normally, this will result in a scrapped part.

What are the pros and cons of thread rolling, compared to regular threading with a threading tool. The threads we cut are no larger than 2″, so nothing to big. Just looking for some info. as i have no experience with thread rolling but have heard it is way quicker, and produces a stronger thread.
