Thread rolling creates a tremendous amount of heat very quickly. Using a water soluble coolant also dissipates heat and helps extend the life of the roll. The savings in machining time that thread rolling can provide over single point threading can be enough to justify the investment in a thread rolling system. Although the axial system cant thread as close to a shoulder as the other two systems, it has the unique advantage of threading larger diameter stock. Since the axial rolls only produce one thread at a time, the heads are simpler in design. Currently, the FETTE axial systems can roll profiles upto 230 mm in diameter.

The rolling cold rolling process is an advanced non-cutting process that effectively improves the intrinsic and surface quality of the workpiece. 1.This machine threads the ends of rebar used during the construction of buildings and other concrete structures. Aerospace industry specifications require that indicating type gauges be used to measure threads. Flat die thread rolling is adaptable for both low and high volume requirements. With high rolling pressure, any malleable material can be processed. Incorporates hydraulic operation for mass production of many types of thread forms on hollow sections for oil pipe connectors, electric fan shafts, automobile and motorcycle parts, jacks and props, cycle hubs, closures, etc. Saspi offers a complete line of High Speed Thread Rollers, including Flat Die Thread Rollers, Rotary Thread Rollers, Washer Assembly Units, and Form Rollers.

Situate the spool of thread so that the spool pin of your machine sits in the center hole of your spool.The thread of the spool should be wrapped around the center in a counter-clockwise rotation. The processor speed will impact how fast the software will calculate and complete tasks. With each release, more and more aspects of Mastercam are becoming multi-core processor aware. Toolpath calculation and Simulation will generally run faster with a multi-core processor. We typically see a 50% reduction in toolpath calculation time with the latest Intel i7 or Xeon processors. Detect collisions between your stock, tool, and machine components before sending code to your machine tool. Machine Simulation is a safe way to prove out 3-axis, 4-axis, or 5-axis Mill toolpaths to make clean, efficient, and accurate programs. Extend tool life with proprietary toolpath strategies that maximize material removal rate and reduce cycle times. The broach holder is mounted stationary while its internal live spindle and end cutting broach tool are driven by the workpiece.

Production rates are usually three to five times faster than thread cutting. The path a multiple-form thread cutting tool travels to create an external thread. We have thousands of part-numbers available, from the most common cams to the very obscure. Whatever your cam needs may be let Modern Cam & Tool Company work with you to supply them. We can engineer special cams for your applications or use your own engineering to make the right cams for you. We have over fifty years’ experience and are the supplier to the OEM. High quality materials, sturdy and durable, not easy to rust. Pure copper motor is stronger and more wear-resistant than ordinary motor, and has a longer service life.

NOTE that it only takes a revolution or 2 for the cam to walk completely forward. If you think you have it threaded correctly, make sure thread isn’t wound around the spool holder. Start at the spool and follow the thread through the mechanisms; make sure it can move freely when you pull gently on the thread. You should notice a small loop coming up from the bottom of your needle plate. Gently tug on your upper thread end to straighten this loop and pull the bobbin thread out from within the shuttle. Loosely hold the end of your top thread with your left hand while turning the outer part of the hand wheel clockwise, or toward you. Rotate the wheel a full turn.Make sure that the presser foot has been raised before doing this. Clip the thread into the first lower thread guide at the bottom of the previous thread path.

In the hierarchy of manufacturing machines, the screw machine sits at the top when large product volumes are needed. An engine lathe sits at the bottom, taking the least amount of time to set up but the most amount of skilled labor and time to actually produce a part. Screw machines may require an extensive set-up, but once they are running, a single operator can monitor the operation of several machines. Mechanical screw machines have been replaced to some extent by CNC lathes and CNC screw machines. However, they are still commonly in operation, and for high-volume production of turned components it is still often true that nothing is as cost-efficient as a mechanical screw machine. Cam-operated chuckers are fading into history faster than most other non-CNC machine tool classes. This is because the few companies that have them tend to be forced to continually adapt to the latest state of the art to compete and survive. Cam-op chuckers may be more likely to be scrapped than other types of non-CNC machine tools. Unlike with “Grandpa’s South Bend lathe” or “Dad’s old Bridgeport knee mill”, virtually no one can afford to keep and use them for sentimental reasons alone. An automatic chucking machine is similar to an automatic screw machine; both use spindles in production.

On the opposite finish of the range, there is the exceptionally specific specialty of high exactness thread rolling head, fundamentally on little groups of parts. We utilize a mix of vertical round and hollow three-pass on machines, even level bite the dust responding machines, and flat barrel shaped two-kick the bucket machines to deliver accuracy threads. Once screw turning machines were in common use, most commercially available wood screws were produced with this method. These cut wood screws are almost invariably tapered, and even when the tapered shank is not obvious, they can be discerned because the threads do not extend past the diameter of the shank. Such screws are best installed after drilling a pilot hole with a tapered drill bit. The majority of modern wood screws, except for those made of brass, are formed on thread rolling machines.

These machines are equipped with lubricating systems to increase the durability of the slides. Cinco Industries sells both new and used Saspi Thread Rolling Machines. Saspi has consistently been an innovator in the machinery industry, which is why Cinco is proud to represent their complete line of high-speed thread rolling machines all throughout North America. With their help, I have successfully implemented a Quick Change System that allows for a reliable tool life management system. With the advent of CNC machines and complicated new part design, having the right tools is one less thing to worry about. These developments of the 1760–1800 era, with the Wyatts and Maudslay being arguably the most important drivers, caused great increase in the use of threaded fasteners. Standardization of threadforms began almost immediately, but it was not quickly completed; it has been an evolving process ever since.

The digital revolution and the linking of components and systems increase the efficiency of machines and equipment.

Don’t forget that much of what was discussed here applies equally to mill-turn centers and multitask lathes, which, thanks to their C-axis capabilities, can thread-mill with ease. These, as well as many 2-axis lathes, also offer rigid tapping—again, be sure to use the correct toolholder for the application. For many, the former is the preferred method of threadmaking on a CNC machining center.

However, better results are obtained by using a lower speed than this. When the roll is held in a holder attached to the cross-slide, and is presented either tangentially or radially to the work, a considerably higher speed can be used than if it is held in a swing tool. This is due to the lack of rigidity in a holder of the swing type. The feeds to be used when a cross-slide roll-holder is used are given in the upper half of the table “Feeds for Thread Rolling;” the lower half of the table gives the feeds for thread rolling with swing tools. These feeds are applicable for rolling threads without a support, when the root diameter of the blank is not less than five times the double depth of the thread. When the root diameter is less than this, a support should be used. A support should also be used when the width of the roll is more than two-and-one-half times the smallest diameter of the piece to be rolled, irrespective of the pitch of the thread. When the smallest diameter of the piece to be rolled is much less than the root diameter of the thread, the smallest diameter should be taken as the deciding factor for the feed to be used.
