Other presentation

[Company strength]
We have a track record of machining unbalanced bodies for high-speed railway motors. Products with irregular shapes that are not center-balanced tend to become eccentric or elliptical due to self-weight in lathing if they are as heavy as about 170 kg. However, our know-how has enabled stable machining. Consult us if you have problems about workpieces with irregular shapes.


[Business description]
Our company manufactures rolling stock shafts, covers, cases, and other parts. We also manufacture semiconductor manufacturing equipment parts and nuclear power-related valve parts, including large pumps and pump casings. We provide high-quality products that clear the standards for various industries. We also design and manufacture our own original machines. We manufacture transmission cases and various other parts for rolling stock, from Shinkansen bullet trains to ordinary trains. Our large parts include gear cases for mining trucks, and we can mass-produce them.


[Industry]
Part machining


[Representative's message]
We manufacture many parts by machining, including motor shafts, turbine motor parts with roundness within 0.01, pump parts, and machine tool bases. We can machine materials such as SUS304, SUS304, SS400, Ni-resist cast iron, SCM435, FCD, Meehanite cast iron, FCD450, and aluminum. We have a track record of manufacturing vehicle-mounted gear boxes for high-speed railway trains from thin aluminum cases. Thin aluminum cases are subject to great deformation as the temperature changes. We control the factory temperature for manufacturing with stable dimensional tolerances.


[Company structure for market development/overseas expansion]
Our factory is ready with the latest manufacturing machines for special large machining, trial manufacturing, high-mix low-volume production, and mass production. Our flexible production system consists of four turning machines over 1,600 mm in diameter, 26 horizontal multi-sided APC machines, and 15 overhead traveling cranes up to 2.8 tons. We can also quickly handle articles by making use of our 2-ton forklift, 1.5-ton forklift, and three 3-ton trucks.
