The spiral spring machine equipped with the computer strictly controls all forming conditions like the speed and the temperature by the numerical value. Especially, this numerical control demonstrates power in the temperature management that controls the quality. Moreover, heat-treatment and the surface treatment also have gone consistently. It obtains good results for rust and noise prevention as we adopt the molybdenum disulfide coating for surface treatment. We are successful in the automation of high quality spiral spring manufacturing by original machine development. In the comprehensive evaluation like the quality, cost, and delivery, we have pride that our products are top level.
