Micro milling machine μV5
µV5 precision machine
Feature
Unique Optical Image Type Tool Measurement System
- To tackle the change of tool bottom position that directly affects the machining accuracy, an image of the tool obtained by a CCD camera under LED lighting is digitally processed. This enables an automatic judgment of the tool bottom position after the displacement is settled to perform tool length compensation.

Accuracy Not Possible with Conventional Compensation Processes
- Inner spindle cooling system and special jet lubrication of bearings immediately saturates the heat generated by rotational frictions. This feature leads to high stability in positioning of tool tip even after a number of repetitive spindle rotations and stoppages, whose accuracy is beyond the capability of conventional compensation method.
- Introducing our unique element technologies into measures against thermal distortion of the column, a wide variety of error factors are eliminated from the high-precision parts and precision mold machining processes for applications such as IT, optics, medical equipment, and semiconductor device.
An Excellent Balance of Precision Micro Machining and Cutting Efficiency
- To address opposing demands, "precision" and "quick delivery", µV5 exhibits high degree of versatility ranging from cutting custom-tailored ultrafine tools to high-efficiency cutting of general-purpose tools.
- Incorporating high-performance wide-range spindle and high-power high-rigidity feed axes into optimally balanced machine design, µV5 realizes high degree of applicability for a wide range of cutting conditions.

High Surface Machining Quality Sustainable Even In Long Hour Repetitive Operations
- To suppress runout and vibration in the whole rotation range, the spindle rotation balance and bearing preload are controlled in a sophisticated manner.
- An optimum structure design that allows high attenuation characteristic of each guide surface as well as high degree of heat-nullification characteristic and machine rigidity achieves optimal machining surface quality on a wide variety of materials.
