Screw Rolling Head for NC Lathe

Screw Rolling Head for NC Lathe

This is designed to enable the rolling processing of screws in water-soluble cutting oils by using grease for the lubrication of the screw rolling rolls and roll shafts.

[NTR 16-NC, 20-NC, 28-NC for NC Lathes] One piece in 2 seconds! We have mastered the speed technique of thread rolling. For thread rolling with a large pitch or when the material is high-tensile steel, we recommend using a higher grade of form for maximum dimensions. The shape and dimensions are the same as the standard NTR. [What is thread rolling?] It is a method of shaping threads by pressing a cylindrical tool (rolling roll) 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, due to the hardening of the surface structure from the pressure during forming, stronger threads are produced.

Standard Type Thread Rolling Head

Standard Type Thread Rolling Head

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.

Screw Rolling Head Open Type OTR Series

Screw Rolling Head Open Type OTR Series

Because the thread rolling rolls protrude from the end face of the main body, thread processing can be done up to the point where the material is chucked without bending, even for small-diameter threads.

One piece in 2 seconds! Master the fast technique of thread rolling, and furthermore, it is possible to process even irregularly shaped threaded parts without interfering with the rolling head body. We offer standard types (open type) OTR 20, 28 and NC lathe type (open type) OTR28-NC. 【What is thread rolling?】 It is a method of shaping the threads by pressing a cylindrical tool (rolling roll) with the shape of the thread profile 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, due to the hardening of the surface structure from the pressure applied during forming, stronger threads are produced.
