Process for manufacturing high precise electroplating CBN (Cubic Boron Nitride) grinding wheel

Abstract

The invention discloses a process for manufacturing a high precise electroplating CBN (Cubic Boron Nitride) grinding wheel, comprising the following steps of: preparing a substrate and abrasive particles; preparing a plating solution; placing sand and electroplating; carrying out contouring improvement treatment on the abrasive particles; and carrying out the post-plating treatment. The inventionhas the advantages that: because the contouring of the grinding wheel abrasive particles is enhanced, the abrasive particles as many as possible are ensured on the same level, more abrasive particlescan be ground at the same time, the grinding efficiency can be enhanced, the unevenness of the surface of a ground workpiece is reduced microscopically, and further the purpose of enhancing the manufacturing precision of the electroplating CBN grinding wheel is realized.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a manufacturing process of an electroplated grinding wheel, more specifically to a manufacturing process of a high-precision electroplating CBN grinding wheel. Background technique [0002] The single-layer electroplated CBN grinding wheel has superior grinding performance, a wide range of grinding applications, and has more and more advantages in forming and high-speed grinding. But at the same time, there are certain disadvantages: the grinding wheel is not suitable for direct dressing, and the manufacturing accuracy of the grinding wheel becomes an important factor affecting the final processing accuracy. Although the most commonly used externally plated grinding wheel has a simple process and low cost, the exposed cutting edges are uneven, the initial grinding surface accuracy is difficult to improve, and the durability of the grinding wheel is low, and the abrasive lo...

But at the same time, there are certain disadvantages: the grinding wheel is not suitable for direct dressing, and the manufacturing accuracy of the grinding wheel becomes an important factor affecting the final processing accuracy

Although the most commonly used externally plated grinding wheel has a simple process and low cost, the exposed cutting edges are uneven, the initial grinding surface accuracy is difficult to improve, and the durability of the grinding wheel is low, and the abrasive loss is serious, which seriously restricts the application of the electroplated CBN grinding wheel.

At present, my country can only produce some electroplated CBN grinding wheels with low precision and simple shape, while high-precision grinding wheels need to rely entirely on imports.
