Technology for high-precision processing from machine tools to rolling stock parts

Our company mass-produces high-precision parts for various industries from machine tools, information equipment, and robots to rolling stock. We also assemble machine tool units and semiconductor manufacturing equipment. We conduct processing with high precision (about 0.005 mm in coaxial, perpendicular, and parallel directions) based on our extensive experience of handling castings, iron, aluminum, and SUS. Our company has a quality management environment to ensure precision. Spindle parts for machine tools require particularly high precision. We have staff with sufficient skills for this assembly work.


Other presentation

[Company Strengths]
We can achieve high precision (about 0.005 mm in coaxial, perpendicular, and parallel directions) based on our extensive experience of handling castings, iron, aluminum, and SUS. We have a quality management environment for this purpose. Our company has many partner factories for casting, thermal treatment, coating, surface treatment, and special machining. Our production system enables one-stop services.

[Business Description]
Our business is high-precision machining and spindle assembly for the machine tool industry. This is why room temperature changes are kept within ±2℃ by central air conditioning to prevent thermal deformation and maintain and accuracy manage processing and measuring. Our company started using CAD/CAM 10 years ago to reduce worker-hours by creating processing drawings and CAM data from customer-supplied electronic data. We also installed our in-house production management system for integrated management of daily order reception and shipping information.

Electric machine and instrument manufacturing

[Product and Technical Strengths]
Our company possesses various machine tools for high-precision machining, such as five-face processing and Yasuda finishing equipment. We also possess CNC coordinate measuring and roundness measuring instruments to realize high accuracy. Spindle parts for machine tools are expected to have particularly high precision, so we also have staff with assembly skills. Our company specializes in high-mix low-volume production.

[Representative's Message]
High precision and high quality are our mottos. We will improve our technical capabilities to contribute to industry by considering high-mix low-volume production as the reason for our company’s existence.

[Company Structure for Market Cultivation and Overseas Expansion]
