Multiple duplicatus grinding type turnable cutter

Abstract

A cyclically ground indexing cutting tool for lathe, planer and borer has a key slot on the rear part of front surface of its head, which is parallel to the dividing line of front angle or perpendicular to primary cutting edge. A locating key for installing the indexing blade is arranged in said key slot, and has a V-shaped opening for contacting two side surface of said indexing blade tightly. A regulating part behind said locating key can drive the indexing blade forward.

Description

Technical field [0001] The invention belongs to the field of metal processing, and relates to a metal cutting tool, in particular to an indexable tool applicable to lathes, boring machines, planers and the like. Background technique [0002] As early as the early 1970s, my country began to focus on the promotion and application of indexable cutting tools. The main structural feature of the indexable tool is a carbide insert with a triangular, square or other polygonal shape, and the cutting edge on each side can be indexed on the tool body. For the clamping form of indexable tools, taking indexable inner and outer surface turning tools as an example, the International Organization for Standardization (ISO) mainly includes C (press plate type), M (composite type), P (lever type), S There are four types (screw type), of which, except for C (press plate type), which can use indexable inserts without holes, the other three must use indexable inserts with holes, and their clampi...

Problems solved by technology

[0003] In the 1980s, the penetration rate of indexable cutting tools in industrially developed countries accounted for about 80% of the total output of cemented carbide cutting tools. On most ordinary lathes, the turning tools selected so far are almost still at the backward level of the traditional welded carbide turning tools. The utilization rate of the blade is low, and the blade is almost not allowed to be re-sharpened, resulting in high consumption of the blade, which is important to the user's unbearable

But the above-mentioned non-porous blade machine clamping tool is only applicable to special-shaped special-shaped blades, and the reset of the main cutting edge and the secondary cutting edge direction of the blade must be adjusted respectively from two directions of the blade, and the precision of the blade reset cannot be controlled. Cannot complete the synchronization of the main cutting edge and auxiliary cutting edge direction of the insert while correctly resetting and positioning, so it cannot be used on indexable tools
