Abstract
A system for clamping a cutting insert on a grooving, threading, or milling tool wherein a top clamp member and a support plate are mounted on the tool's surface. The contacting surfaces of the tool, clamp member, and support plate are ground to a smooth finish. A cutting insert is formed with upper and lower V-shaped surfaces and is received in corresponding V-shaped recesses formed in edge portions of the top clamp member and the support plate. Bolts having left hand threads secure the top clamp member to the tool so as to clamp the insert between the top clamping member and the support plate.
Claims15
A tool adapted for use in metal cutting comprising:
- a body member, said body member having a ground planar surface;
- a support plate, said support plate having a ground planar inner surface and an upper edge;
- a top clamp member, said top clamp member having a ground planar inner surface and a lower edge;
- means for attaching said support plate to said body member such that said inner surface of said support plate interfaces said planar surface of said body member, said means for attaching said support plate comprises bolts;
- means for attaching said top clamp member to said body member such that said inner surface of said top clamp member interfaces said planer surface of said body member and such that said lower edge of said top clamp member is spaced from said upper edge of said support plate, said means for attaching said top clamp member includes two conically shaped bores asymmetrically spaced on said top clamp member;
- a cutting insert mounted between said support plate and said top clamp member;
- an upper surface formed on said cutting insert and engaged with said lower edge of said top clamp member;
- a lower surface formed on said cutting insert and engaged with said upper edge of said support plate.
