Achieving Accuracy through mechanical means

Utilizing structural analysis simulations, the modular machine structure of U3 achieves good rigidity even under extreme conditions.

Geometric accuracy is achieved through proven machine structure and not just obtained from electronic compensation.

Casting cooling system to achieve thermal stability
Machine temperature control (standard specification)

The interior of the machine is kept to the same temperature as the dielectric fluid, which is controlled by the dielectric fluid cooling unit. This reduces thermal distortion of cast iron machine components to provide high-accuracy machining. Moreover, the dielectric fluid cooling unit incorporates an inverter system to minimize the temperature difference between its On/Off states. The temperature is controlled with high accuracy to within ±0.1°C.
