Taper Rolling Unit for Leaf Spring

CNC Taper Rolling Unit for Leaf Spring
LTP202R

Overview

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.
