Cutting tool having cylindrical ceramic insert |
摘要 |
A ceramic insert for a tool holder is in the shape of a tapered cylinder wherein the diameter increases outwardly along the insert length, from a first end to a second end. The second or upper end of the insert has a bevel around its circumference; the intersection of the bevel and tapered sidewall of the cylinder provide a cutting edge which has a negative rake and relief angle which are desirably constant around the insert. Thus the insert may be mounted on a neutral plane in a tool holder and a tool will cut equally well in any direction along a 180 DEG arc. Various engagement and clamping means are used to hold the insert in place in the tool holder.
