Wire springs
Machine name: Forming machine
This is a device that automatically forms torsion springs and tension springs with high precision. It is capable of processing complex shapes and stable quality control.
Machine name: Coiling machine
Equipment that processes compression springs. It operates based on a program set according to the shape and dimensions, allowing for high-speed and precise manufacturing.
Press related
Machine name: 300t progressive press
Press processing in which multiple processes (punching, bending, drawing, etc.) are performed continuously while feeding coil material. By moving the material through the processes in order, high-speed and high-precision mass production processing is possible.
Machine name: 150t progressive press
Machinery (mold production)
Machine name: Ultra-precision wire electric discharge machine
Electric discharge machine capable of nano-level high-precision processing. It can process fine and complex shapes, and can also handle high-hardness materials.
Machine name: NC milling machine
A numerically controlled (NC) milling machine capable of high-precision cutting of complex shapes. We can handle everything from small-lot production of a wide variety of products to mass production.
Inspection
Machine name: Automatic compression and tension spring testing machine
The characteristics of compression and tension springs can be measured with high precision.
Machine name: Automatic torsion spring testing machine
The characteristics of torsion springs can be measured with high precision, and can be used for quality control and development.
Machine name: Projector/Image dimension measuring machine
A device that performs high-precision dimension measurement without contact. Rapid and stable measurement is possible.
