Superhard material W-shaped blade dislocation tool

Abstract

The invention discloses a cutting tool with indexable inserts which is made of ultra-hard material provided with a W-shaped blade, comprising a knife body and a blade connected at the front end of the knife body. The front end of the knife body is provided with a blade mounting slot; the bottom of the blade mounting slot is provided with a shim which is used for placing the blade; a blade press plate tightly presses the rear part of the blade; the blade press plate is tightly fixed on the knife body through a press plate screw; the lower part of the rear end face of the blade press plate is an inclined surface and the blade press plate is embedded into the blade mounting slot along the inclined surface. Aiming at solving the problems of existing ultra-hard material cutting tools such as no indexing at any time, unstable blades and poor hardness and thermal stability, the invention provides an ultra-hard material cutting tool with indexable inserts, stable blades and good hardness and thermal stability. The cutting tool has the advantages that the blade can be adjusted into variable positions; the blade is not displaced during the processing; and the cutting tool has better thermal stability, chemical inertia and toughness.

Description

A superhard material W-shaped blade indexable tool Technical field The invention relates to a cutting tool, in particular to a cutting tool for processing superhard materials. Background technique With the development of material technology and manufacturing technology, a variety of high-performance new materials continue to emerge, bringing greater difficulties to cutting. 1. The traditional W-shaped inserts indexable tool inserts are mostly made of cemented carbide materials and ceramics. The clamping methods of the inserts are mostly lever type, eccentric type, screw type, upper pressure plate type, etc. There is a gap between the groove and the blade, so , When the tool path changes, the blade is prone to a small range of displacement, causing machining errors. 2. The traditional W-shaped inserts indexable tool inserts mostly use cemented carbide materials and ceramics. With the development of material technology and manufacturing technology, a variety of high-performance ...
