Factories and facilities for manufacturing precision equipment and parts

Isothermal (constant temperature) machining room

Temperature change is an archenemy to precision machining, and we minimize the influences on materials and machines by maintaining a constant temperature in our factories. Ultra precision machining is realized in our isothermal machining room, where the temperature is kept at 24℃±0.5℃ (summer) and 20℃±0.5℃ (winter).

In machining rooms, vibration control is important along with temperature control. In order to realize accurate and reliable machining work, our machining room boasts a 1 meter thick concrete floor, with more than 100 piles underneath the floor to support machines in the room.

5-axis machine tools for flexible work

5-axis machine tools are essential to work on products with complicated shapes and surfaces. We introduced state-of-the-art tools made by HERMLE (Germany) and YASUDA PRECISION TOOLS (Japan), and have been pursuing speed and accuracy.

Clean room

Precision assembly and evaluation are carried out in a temperature controlled clean room.

Machines

U-Corporation has sixty-one machining centers and milling machines in total.
The total number exceeds one hundred including lathes, grinders, and EDMs (electric discharge machines). With these machines, we can accept clients’ requests for short lead time.
