Feature

Spindle designed for high speed and precision machining

  • Thermal controlled lubricant oil is circulated in the spindle equipped with high power motor.
    Furthermore jet lubrication with thermal controlled lubrication oil keeps bearing pressurizing at all rotation zone, which is suitable for machining efficiently hard work piece at low-speed zone.

High rigidity feed mechanism

  • LH250's feed mechanism has special guide way which reduces friction power and prevents heat generation in order to achieve smooth feed motion and more accurate positioning during long time and high speed machining.
    And twin ball screw system and double long carriage ball guide way are adopted in X axis in order to reduce vibration and get rigidity and make the machine table motion more stabile.

 

Optical image type automatic tool measurement system

  • Optical image type automatic tool measurement system can be chosen as option. This system has good reputation for micro milling machine μV1.
    This system measures the tool in non-contact while the tool under the actual marching condition and capture a series of images of the rotating tool at a high shutter speed and digitally process these acquire information on the tool position.
    These acquired information enables more accurate tool length compensation.
    And it is possible to use separate settings for rough cutting process requiring less accuracy and for the finishing process where accuracy is critical.
