Abstract
The current invention proposes sharpening thin hardened metal blades with the hard turning process using a holder designed to hold the blades in a firm and stiff manner and a ceramic cutting tool held in a fixture. Generally, the cutting tool is held stationary in its fixture while the workpiece, in its holder, is rotated such that it repeatedly comes into controlled contact with the cutting tool. In sharpening operations such as proposed here, it is critical to (i) hold the workpiece firmly and rigidly, and (ii) position the cutting tool in a precise, predictable and reliable manner.
Claims6
A method of sharpening hardened thin metal blades, said method comprising:
- a. holding the thin hardened metal blades in a fixture;
- b. holding cutting tools in a jig in a manner such that at least one cutting tool in the jig corresponds to one blade in the fixture;
- c. rotationally repeatedly bringing each metal blade in the fixture into contact with its corresponding cutting tool;
- such that the blades are sharpened.
A method of sharpening at least one hardened thin metal blade, said method comprising:
- a. holding the at least one hardened thin metal blades in a fixture;
- b. holding at least one cutting tool in a jig in a manner such that the at least one cutting tool in the jig corresponds to one at least one hardened thin metal blade in the fixture;
- c. rotationally repeatedly bringing the at least one hardened thin metal blade being held in the fixture into contact with the at least one cutting tool that corresponds to the at least one hardened thin metal blade;
- such that the blades are sharpened.
