Abstract
A tool includes a cutting head and a holder, wherein the cutting head and the holder form two cooperating surfaces that are pressed together. The surfaces possess rows of alternating parallel grooves and ridges for locking the surfaces to each other. Each of the surfaces has two rows of grooves, one row oriented 90.degree. relative to the other row. On one of the surfaces, some of the grooves of one row are in non-intersecting relationship with the grooves of the other row. On the other surface, the rows extend completely across one another, whereby the rows together form a waffle-like pattern. The cooperating surfaces allow at least four separate relative positions between the cutting head and holder.
Claims6
A chip removing machining device comprising first and second parts having first and second support surfaces, respectively, facing one another;
- each of the first and second support surfaces including at least first and second portions, each of the first and second portions having alternating parallel grooves and ridges, the grooves of the first portion being oriented at an angle relative to the grooves of the second portion;
- the first and second support surfaces being pressed together to produce a meshing relationship between the ridges of each support surface with the grooves of the other support surfaces;
- the first support surface having the first and second portions thereof arranged such that at least some of the grooves of the first portion thereof are in non-intersecting relationship to the grooves of the second portion thereof, and at least some of the grooves of the second portion thereof being in non-intersecting relationship to the grooves of the first portion thereof;
- the second support surface having the first and second portions thereof arranged such that a plurality of the grooves of the first and second portions thereof intersect one another.
