Single-edge diamond cutting tool with adjustable outer diameter and replaceable cutting edge

Abstract

The invention provides a single-edge diamond cutting tool with an adjustable outer diameter and a replaceable cutting edge, and relates to a diamond cutting tool. The single-edge diamond cutting tool with the adjustable outer diameter and the replaceable cutting edge, provided by the invention, can realize accurate high-speed cutting by being matched with a micro grinding process platform. The single-edge diamond cutting tool comprises a front tool rest body, a rear tool rest body, a single-edge diamond cutter, an inverted ladder-shaped tool apron, a tool apron adjusting cushion block and a cushion block adjusting screw rod, wherein the single-edge diamond cutter and the inverted ladder-shaped tool apron are in threaded connection, a spring is arranged between the top part of the inverted ladder-shaped tool apron and a groove of the rear tool rest body, the cushion block adjusting screw rod is fixed on the rear tool rest body, the end part of the cushion block adjusting screw rod is connected with the tool apron adjusting cushion block, the inverted ladder-shaped tool apron is fixed in the groove on the rear tool rest body, and the front tool rest body and the rear tool rest body are fixed into a whole.

Description

technical field [0001] The invention relates to a diamond cutting tool, in particular to a single-edged diamond cutting tool with adjustable outer diameter and replaceable cutting edge. Background technique [0002] Manufacturing is the pillar industry of the national economy, and grinding is an important field of manufacturing technology. It is the most effective and widely used basic technology for precision machining and ultra-precision machining in modern machinery manufacturing. With the needs of industrial development and the continuous breakthrough and innovation of material science, various new materials with high strength, high hardness, corrosion resistance and high temperature resistance have emerged. With the demand of high precision and high quality of products, grinding technology has been widely used and developed. [0003] The traditional grinding wheel has good surface quality and high machining accuracy, but there are random and indeterminate abrasive part...

AI Technical Summary

Problems solved by technology

[0003] The traditional grinding wheel has good surface quality and high machining accuracy, but there are random and indeterminate abrasive particle shapes and distribution rules, a large ratio of normal force to tangential force, high grinding specific energy, high grinding temperature and grinding process The medium abrasive grains are easy to fall off, etc.; while the cutting tools used in cutting are made manually, the geometric shape (such as rake angle, rear angle) and distribution of the tool can be controlled manually, and the ratio of normal force to tangential force is small, which is harmful to the machine tool. The rigidity requirement is relatively low, and the cutting efficiency is high, but compared with the grinding process, the surface quality of the workpiece is low and the precision is poor.
