We have the unique design of non-cam and non-rocker,the CNC computer spring machine independent control
by multiple servo motor.
(the speed of debug machine is over 50 percent faster than the traditional cam
machine, fast production, precision positioning,steady operation;
all one-time forming as for the
high challenge, multi-folder spring, without additional processing.)
