Abstract
Provided is a cutting apparatus 10 including a workpiece fixing jig 2 that supports a workpiece 1, rotates by operation of rotary drive means 3, and rotates the workpiece 1 while fixing the workpiece 1; rotary drive means 3 for driving and rotating the workpiece fixing jig 2; support means 4a to 4c for supporting the workpiece 1 while rotating along with rotation of the workpiece fixing jig 2; cutter knives 5a and 5b that cut the rotating workpiece 1 at least at axially opposite ends of the workpiece 1; and slide moving means 6 for slidably moving the cutter knives. The cutting apparatus 10 having a simple apparatus configuration does not produce chips as a result of cutting with small variations in size and with high planarity of cut surfaces.
Claims6
A cutting apparatus comprising:
- a workpiece fixing jig that supports a longitudinal hollow resin molded product as a workpiece so as to hold an outer peripheral surface of the workpiece between two half cylindrical members from opposite sides and rotates the workpiece while fixing the workpiece;
- rotary drive means for driving and rotating the workpiece fixing jig;
- support means for supporting the workpiece fixing jig while rotating along with rotation of the workpiece fixing jig;
- a cutter knife that cuts the rotating workpiece at least at axially opposite ends of the workpiece;
- and
- slide moving means for slidably moving the cutter knife, wherein
- connection between the rotary drive means and the workpiece fixing jig is achieved by meshing of a gear of the rotary drive means with a gear of the workpiece fixing jig.
