Indexable face milling blade and face milling tool bit using same

Abstract

The invention discloses an indexable face milling blade. The face milling blade comprises a blade base body (1) and a cutting body (2) laminated on the upper surface of the cutting body (2). The indexable face milling blade approximates to be in a prismatic table shape and comprises a positioning side face (11), an upper plane (12) and a positioning bottom face (13). The projection of the edge of the positioning bottom face (13) or the extension line of the edge of the positioning bottom face (13) on a front tool face (21) intersects with the corresponding edge of the front tool face (21) or the extension line of the corresponding edge of the front tool face (21) to form a face deflection angle (23). The face, making contact with a to-be-machine piece, in the cutting body (2) is the front tool face (21). Optionally, a rear tool face (3) is arranged between the front tool face (21) and the positioning side face (11), so that the phenomenon that in edge repair grinding, a positioning side face is damaged is avoided, stabilization and long-acting of a positioning benchmark are ensured, and the cutting face milling blades and the sleeking face milling blades are universal for the same tool disc clamp grooves. The invention further provides a tool bit using the indexable face milling blades, so that the quantities and positions of the cutting face milling blades and the sleeking face milling blades are set on the tool discs with the same tool disc clamp grooves according to requirements.

Description

technical field [0001] The present application relates to the field of face milling cutters, in particular to an indexable face milling insert and a face milling head using the insert. Background technique [0002] The face milling cutter is a processing tool used for large-area metal surface processing. Its cutter head generally includes two main parts: a cutter head and a blade arranged on the cutter head. The blade is used for cutting the metal surface. [0003] Usually, the part used to perform the cutting operation in the face milling cutter, that is, the blade, the cutting materials used in the cutting edge part mainly include polycrystalline diamond and polycrystalline cubic boron nitride, etc. These cutting materials are usually expensive, and the square mm on price. In order to reduce the cost of face milling cutters, in the prior art, the cutting material is usually laminated on the alloy matrix of the insert to obtain a composite insert. Among them, there is a s...
