Abstract
The flange cover covering the blade is divided into two. The second cover is turnably connected to the first cover through a shaft parallel with the spindle of the blade, and the second cover is opened and closed in connection with vertical movement of the spindle. When the spindle is moved upward for replacing the blade, the second cover is automatically turned to the opening position, and L-shaped coolant jetting nozzles are moved away from positions below the blade to positions beside the blade. Thus, the blade can be easily replaced, and an automatic blade replacing system can be applied.
Claims4
A dicing machine which processes a work with a rotary blade, the dicing machine comprising:
- a spindle on which the rotary blade is attached and rotated about an axis, the spindle moving in a vertical direction in processing of the work;
- a turnable cover which covers the rotary blade in processing of the work;
- an axis on which the turnable cover is turnably arranged, the axis of the turntable cover being parallel with the axis of the spindle;
- and
- a nozzle through which liquid is applied toward the rotary blade in processing of the work, the nozzle being arranged on the turnable cover,
- wherein the turnable cover is rotatable about its axis during movement of the spindle in said vertical direction so that the nozzle is moved away from the rotary blade.
