STEP 2TAPER ROLLING
Taper Rolling Machine
The material of leaf spring can be tapered thinly by pressure of taper roll.
CNC Taper Rolling Unit for Leaf SpringLTP202R
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.

Fork Arm Rolling MachineLTP405
Overview
This is rolling machine to roll the leaf thickness and width of heated fork arm material. The width is rolled by squeezing roll, and the leaf thickness is rolled by working Roll & Draw bench. The tapered shape can be formed by NC for up/down movement of upper roll (Electric servo system) without changing forming dies. This machine has a function to storage the product shape data of a various kind.
