Gear/Pulley
The control
technology
by the electronics the turn transmission parts (the pulley ratchet sprocket
etc. with the gear/tooth) that is one of an important machine element progresses
in recent years and have come to be demanded high accuracy. Our company is working at the improvement of technical development/equipment to respond to these
