4 grinding techniques for diamond grinding wheels

Diamond grinding wheel is a highly specialized abrasive tool widely used in precision grinding and processing of hard materials in industrial fields. It uses diamond abrasives as raw materials and is made of different types of binders, which endow it with various application characteristics.

In industrial production, diamond grinding wheels are widely used for high-precision grinding of hard materials (such as metals, ceramics, glass, rocks, concrete, etc.). Its wear resistance, high hardness and excellent grinding efficiency make it a must-have tool. Not only that, diamond grinding wheels can also be used to dress, grind and polish various workpieces to meet precision requirements.

As a professional grinding tool, diamond grinding wheel has a variety of grinding methods, each of which plays an important role in different application scenarios.

Longitudinal grinding method: Longitudinal grinding is one of the common grinding methods of diamond grinding wheels. Its characteristic is that the relative movement direction between the grinding wheel and the workpiece is longitudinal, that is, the grinding is carried out along the length direction of the workpiece. This grinding method is suitable for situations where the surface roughness of the workpiece is low but the precision is high. Due to the high rotation speed of the grinding wheel, the grinding efficiency is relatively low, but the resulting surface quality is better

Lateral grinding method: Lateral grinding, also known as the grinding technique, is another common grinding method for diamond grinding wheels. In this way, the relative movement direction between the grinding wheel and the workpiece is transverse, that is, the grinding is carried out perpendicular to the length direction of the workpiece. Compared with longitudinal grinding, transverse grinding has higher grinding efficiency, but it will generate greater grinding force and temperature, so sufficient coolant is needed to maintain the stability of grinding wheel and workpiece.

Compound grinding technique: compound grinding is a grinding method that combines longitudinal grinding and transverse grinding. In compound grinding, longitudinal grinding is usually used for rough grinding, followed by transverse grinding for fine grinding and finishing. This method combines the advantages of the two grinding methods, which improves the grinding efficiency and surface quality.

Deep grinding method: Deep grinding is an efficient grinding method, which is characterized by the removal of a large amount of material from the workpiece in a relatively short period of time. This method is suitable for fast trimming of workpieces or removal of thicker surfaces. However, the deep grinding method requires more complicated grinding wheel repair technology, higher requirements on the overall structure of the workpiece, and sufficient cutting-in and cutting-out lengths.

Choosing the right grinding method depends on the specific application requirements, including grinding material, grinding accuracy, grinding efficiency and surface quality, etc. In industrial production, the optimization and precise control of grinding process is an important link to improve production efficiency and product quality. Therefore, the research and application of diamond grinding wheel grinding methods will continue to be valued and concerned by engineers and technicians.

At the same time, safe handling is paramount when working with diamond grinding wheels. Operators must wear appropriate protective equipment to avoid accidental injuries caused by broken grinding wheels or splashed workpieces. In addition, it is necessary to ensure that the selection and operation of the grinding wheel comply with relevant standards and specifications to ensure the efficiency and quality of grinding.

We mainly talked about the grinding method earlier, but for different grinding needs and applications, diamond grinding wheels can be classified according to different binders:

Metal bonded grinding wheel: with metal powder as the main bond, it is suitable for high-speed grinding and rough grinding of hard materials. This type of grinding wheel has good heat dissipation performance and has a high surface roughness to the workpiece

Resin bonded grinding wheel: with resin powder as the main bond, it is suitable for precision grinding and smooth processing of hard materials. The resin-bonded grinding wheel has good strength and toughness, and the sand particles are easy to release during the grinding process and are not easy to block, so it is suitable for workpieces that require high precision surfaces.

Ceramic bonded grinding wheel: ceramics are used as the main bond, which is suitable for grinding work under high temperature and high pressure environment. The ceramic bonded grinding wheel has high hardness and wear resistance, and the grinding effect on high hardness materials is remarkable.

Electroplated metal bonded grinding wheel: The surface of this type of grinding wheel is coated with a metal layer, which is suitable for grinding workpieces that require high precision, such as optical glass and gemstones

In general, as a highly specialized grinding tool, diamond grinding wheels play an irreplaceable role in the field of industrial manufacturing and precision machining, providing efficient and accurate solutions for the grinding of various materials.
