Taper Rolling Machine

The material of leaf spring can be tapered thinly by pressure of taper roll.

CNC板バネ先端圧延ユニット LTP202R

CNC Taper Rolling Unit for Leaf SpringLTP202R


This machine performs to roll a heated end of raw material of leaf spring to a tapered shape. Taper rolling is done by upper and lower working roll(round shape) and a draw bench. Any shape of taper can be formed by CNC control of up/down movement(Electric Servo System) of an upper roll. Consequently, this machine is most suitable for parabolic taper rolling. This machine has a capacity to store a shape data of many types of products.
