Features

High Precision and High Rigidity

This is a compact spindle motor with a built-in high-precision, high-power DC brushless motor. The unit comes with a precision angular bearing built into the main shaft and this allows the unit to perform deep-cut processing.

Dedicated High Performance

The rotation speed of the main shaft can be arbitrarily set by the inverter. High-level waterproof performance is obtained by combining air purge, via the motor cooling air, and labyrinth seals.

Application Examples

  • Work such as drilling and end milling is done in combination with a slide unit.

  • Deburring is done in combination with a robot.

  • Various types of cutting can be done by mounting the unit on special purpose machines.

Specifications

Notes:

  • The selection of models should be based on the shape of the workpiece, material, cutting characteristics, diameter and material of tools, rotation speed (cutting speed), etc.

  • The drilling capacity displayed in the above table is based on values representing a drilling depth of two times the diameter of the drill.

  • Power-supply voltage is 3-phase AC200V±10%, 50/60 Hz.

  • To cool the built-in motor, please supply clean, dry air from the air supply aperture.

  • Make sure not to block air vents used for motor cooling with clamps, etc.
    Furthermore, please make sure that the vents are always facing in the downward direction.

  • Cable pull-out direction differs depending on the the model number.
