Both Superior and its customers benefit from the increased efficiency and decreased cost associated with successful lean manufacturing methods. Superior Thread Rolling is a world-class precision manufacturer with a promise to remain at the forefront of technology and customer service in the 21st century. A programming sample has been written for rolling our ½-13 thread, 3 inches long, located in station 8 on the turret. After the thread is rolled, we index to station 10 and move the head against a pre-positioned angle bracket to reset the head. This method will provide you with an idea of the head’s alignment and the direction of any misalignment. The final objective is to get the rollers in position on a correctly sized blank to produce the specified thread size and quality.

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.

Higher quality of chipless manufactured parts are the decisive argument for changing of the way of thinking in profile rolling technology. With our range of machines we are able to produce highly accurate parts economically even in the smallest of batch runs.

Our facilities allow us to handle both large and small orders with a proven track record for successfully handling large inventory requirements.

We strive to continuously stay on the cutting edge in all of our manufacturing operations. For example, the head can be positioned so a standard turret index swipes the handle past a fixed object like the lower way cover, a second turret, tailstock, bracket, and so on, thus closing the head automatically. Please appreciate that the roller forces will be greater than your hand-tight initial setting. You can assume that the rolls will need to be adjusted slightly smaller–one-half to one mark in the negative direction on the calibration scale. Pre-rolled chamfer angles of 10 to 30 degrees from the part center line are recommended. For stronger workpiece materials and coarser pitches, smaller angles of 10 to 20 degrees should be used. Most of the material that is displaced below the pitch line will flow above the pitch line. However, some of the material will be compressed and some will elongate.

(We normally hold 63 or better UOS. They wanted better.) I’ve never tried going to a coarser finish once we started doing our own thread rolling. Besides a good finish, you will need to hold a consistent size. The first time you roll a thread will require some playing with OD size, and thread roll adjustment to find the proper combination for holding pitch and Major Diameter tolerances. Machine was rebuilded in 2019, complete Hardwere, and pneumatic components, and part from electric. Machine can be used for serial tube production, can be aded Robot for manipulating.

When parts are produced in larger quantities, single point threading’s versatility is less beneficial. great deal of the stuff you get at the nearby home improvement shop, similar to wood screws, slack fasteners, and machine screws. Thread rolling is a cycle that has been around for more than 100 years and there are cnc threading machines in administration that make the fifty-year old ones look youthful by correlation. Thread rolling machine manufacturer in China can offer various of machines for overseas market. Threads of metal fasteners are usually created on a thread rolling machine.

TB-30A 500KG three dies rolling machine is specially designed for hollow parts,tubular processing, easy to operate. Chamfer angle–A common mistake in thread rolling is starting with an angle on the pre-rolled blank that is the same as the angle to be produced on the finished part. Like the blank diameter, the pre-rolled chamfer angle will be altered by the displacement of material during the thread rolling process. The final blank diameter will be determined after adjusting the thread rolling head to produce the part’s final pitch diameter. Changes can then be made to the blank diameter to produce the part’s nominal diameter. But because the head is self-feeding, a feed rate approximately 0.001 to 0.002 inch less than pitch can compensate for the material’s elongation and helps to provide optimum roll life. More optimum results will be obtained by feeding the thread rolling head at 0.075 ipr. There is a simple method of optimizing thread rolling speed for a lathe. The least amount of spindle load means the material is flowing with the least resistance. Using the spindle load meter built into most CNC turning centers, the best rpm for an application can be determined.

A vertical three die process is often used when tight concentricity is important. Bearing of the rolling spindle with fully rolling, cageless cylinder roller bearings.

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.

It uses equalized thread rolling pressure to eliminate part deflection, thereby improving thread concentricity.This system is available in the 134-SA and 162-SA models.
