    PEE-WEE® CNC Standard cold forming machines with rigid full cast design and dove tail guide ways are offered from 15to to 35to capacity. They are perfectly manufactured for threads profiles and serrations (optionally accessory with "hydraulic back lash compensations"). The roll form slide axis is CNC controlled. Cold Forming Internal Threads With Taps Internal threads can be produced by a cold forming or swaging process. The desired thread is formed in the metal under pressure and the grain fibers as in good forging follow the contour of the thread. These grain fibers are not cut away as in conventional tapping.

    Thread rolling is primarily a cold forming process done at room temperature but a niche does exist for hot rolling when materials are greater than Rockwell C 45 because die life would be seriously compromised. Like centerless grinding its sister process the thread rolling process can be in-feed or thru-feed. The traditional method of threading is mainly to use a forming tool or a grinding tool to machine a thread on a workpiece. There are mainly turning milling tapping wire grinding grinding and cyclone cutting. When turning milling and gr

With forming without cutting there is a further differentiation between cold and hot forming. The cold-forming taps of this invention can be thread-ground on conventional thread-grinding equipment without the need or use of extensive cam-relieving action. The thread form of this invention is ground concentric with the tap axis and is accomplished by creating the lobe configuration on the tap blank prior to the thread-grinding

  • CNC Machining CNC Turning Forgings Cold Forging

    Cold forming is a process that is preferred for small-medium parts due to its low cost volume output and better mechanical properties of the parts formed. It is also preferred due its ability to offer near to the final part shape and better surface finish too. Well backed up by a sophisticated infrastructure Irya offers many cold forged/formed components with all the necessary value adding Thread rolling also has the advantages of being a must faster production process. Thread rolling is also referred to as a cold-forming process. Thread Grinding. Another method of creating threads is by utilizing the grinding process. Thread grinding yields threads with exacting tolerances and are used in applications where precision is key.

    Thread rolling is primarily a cold forming process done at room temperature but a niche does exist for hot rolling when materials are greater than Rockwell C 45 because die life would be seriously compromised. Like centerless grinding its sister process the thread rolling process can be in-feed or thru-feed. Thread rolling is a cold forging process that can be performed on many types of ductile metals to reshape a round diameter into a thread form. In this process a blank is fed into a machine in between rolling dies in order to produce the thread. Thread

  • Cold Headed FastenersCustom Cold Forming Abbott Interfast

    Constructed from steel we used high-speed multi-blow cold heading machine and a series of dies and punches to form the desired geometry. We transferred the parts to a CNC machine to secondarily machine to achieve a tolerance of ±0.001 on the head diameter and reduce the shafts for thread Tapping via cold forming is appropriate for materials with tensile strength less than 1 200 N/mm2 and fracture strain of 5 percent. As a rule of thumb if a continuous chip is created when drilling then the material is likely a good candidate for cold forming the threads. However suitable materials react to cold forming in different ways.
