Problems solved by technology

[0002] Material civilization has injected new vitality into people's spiritual life, especially the rapid development of science and technology, which makes new products and new materials appear continuously, which greatly enriches the needs of people's lives. With the improvement of people's living and economic conditions , air conditioners and refrigerators have entered thousands of households, and the compressor components of air conditioners and refrigerators, such as crankshafts, roller sleeves, sliders, upper and lower covers, etc., require high precision, and the materials used are generally high-speed steel, etc. Difficult-to-grind materials, abrasive tools made of silicon carbide and corundum have low processing efficiency, frequent dressing, roughness, and difficulty in meeting requirements. High, it is difficult to accept economically, therefore, the grinding tools for high-strength parts processing need to be innovated and improved

Embodiment Construction

[0007] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] Depend on figure 1 Given, the grinding wheel of the present invention has a mounting hole 2 in the center of the grinding wheel base 1, and the upper and lower ends of the mounting hole are concentric with the mounting hole 2 to have a card slot 3. Cubic boron nitride grinding surface layer 4 is fixed on the periphery through bonding layer 6 .

[0009] The grinding wheel substrate 1 is a hollow metal disc body, and cubic boron nitride is the so-called super-grinding CBN material on the market. The size of the substrate can be made into a series of products as required.

[0010] The diameter of the grinding wheel is generally 208-4000mm; the thickness of the base is generally 12.5-30mm; the diameter of the internal fixing hole is generally 32-203mm; the width of the grinding wheel is generally 6mm; the height of the grind...

Abstract

An abrasive cubic boron nitride disc for grinding slot is composed of a basic body with flat periphery and a surficial grinding cubic boron nitride layer. Its preparing process includes such steps as mixing raw materials, shaping, drying, sintering, testing, trimming, adhering said surficial layer, and hardening. Its advantages are high grinding precision, low cost and long service life.

Description

1. Technical field [0001] The invention relates to a grinding tool, in particular to a cubic boron nitride groove grinding wheel and a manufacturing method thereof. 2. Background technology [0002] Material civilization has injected new vitality into people's spiritual life, especially the rapid development of science and technology, which makes new products and new materials appear continuously, which greatly enriches the needs of people's lives.
