  • The standard type has a threaded hole in the center of the attractive face to facilitate mounting of a jig or fixture for workpiece alignment.
    *Additional working on the center thread hole is allowed up to M10 for the chuck size φ160 and M12 for φ200 or over. (Additional working on the threaded hole of the φ125 type only is not possible.)
  • There is an additional working allowance of 5 mm from the attractive face to allow additional working according to jigs and fixtures.
  • The permanent magnetic type requiring no electricity can be mounted easily without a need of considering wiring. Also it contributes to energy saving.
