It performs screw machining by attaching a screw rolling head to the cross slide of various lathes and single-purpose lathes and feeding it vertically against the axis of the material.
【Standard Type NTR 16, 20, 28, 36】 One piece in 2 seconds! This is a versatile type that has mastered the rapid technique of thread rolling and can accommodate various types of screws. For thread rolling of screws with a large pitch or when the material is high-tensile steel, we recommend using a higher grade model for maximum dimensions. 【What is thread rolling?】 It is a method of shaping screw threads by pressing a cylindrical tool (rolling die) with the thread shape engraved on it against the base material, causing plastic deformation of the base material to form the threads. It is a type of forging process. In thread rolling, since the threads are formed through plastic deformation, the flow lines are not destroyed, and additionally, the hardening of the surface structure due to the pressure applied during forming results in screws with higher strength.

basic information
**Features of the SIS Thread Rolling Head** ○ Capable of processing at high speed → Rolling time is approximately 2 to 3 seconds → Processing time is truly 1/20 compared to cutting processes ○ Simultaneous cutting processing is possible → After cutting the rolled material diameter with one machine, thread rolling can be performed at the same speed while maintaining simultaneous chucking ○ Strong, uniform, and capable of high precision thread processing → Once the rolls are set, thread precision remains very stable even during continuous processing, easily achieving JIS Grade 1 threads → The finished surface of the threads becomes mirror-like, strong, and improves end face runout precision ○ General-purpose type capable of processing various types of threads → By simply changing the rolling rolls, various types of threads can be rolled with the same head → Extremely high versatility and cost performance ○ Easy to install on various machines → Designed compactly, making it easy to set up on any machine → Can be easily used on multi-spindle automatic lathes, NC lathes, dedicated machines, single-purpose machines, and standard lathes by adding a hydraulic cross slide feeding device on the bed ○ Short setup time → When changing the type or dimensions of the threads, just replace the rolling rolls → Ideal for small-batch production of various types ● For more details, please download the catalog or contact us.
