The basics of double disc grinding machines in detail

Double disc grinding machine, as a kind of high-efficiency surface processing machine tool, has occupied an important position in industrial production since the 1950s. It has been widely used in many fields such as bearings, automotive parts, magnetic materials, etc. with its high precision and high efficiency. Below, we will take a detailed look at the basics of double disc grinding machine.

The working principle of the grinding machine is to grind both end faces of the workpiece by two grinding wheels at the same time in order to achieve high-precision flat surface machining effect. During the machining process, the workpiece is clamped on a table, which is accurately positioned by a mechanical clamping system. The table is usually equipped with an adjustable feed system, which ensures that the workpiece remains in line with the plane of the grinding wheels during the grinding process. Two grinding wheels rotate at high speeds to make contact with the two end faces of the workpiece and grind it. The rotational speed of the grinding wheels and the grinding pressure can be adjusted according to the requirements of the workpiece material, machining accuracy and surface finish.

Double disc grinding machines are available in various structural designs and are mainly classified into two types: horizontal and vertical. Horizontal double disc grinding machines are suitable for processing larger workpieces, while vertical double disc grinding machines are more suitable for processing small or thin workpieces. According to the different feeding methods, the equipment can be further classified into penetrating, rotary and reciprocating types. All these different designs are designed to better suit the processing needs of different workpieces.

In terms of material selection, the grinding wheel material and grit size of the double disc grinder are key. Common grinding wheel materials include CBN (cubic boron nitride), diamond and other hard abrasives, which have high hardness, high wear resistance and high thermal stability, and can meet the processing requirements of different workpieces. The grain size of the grinding wheel determines the fineness of the grinding, the finer the grain size, the higher the surface finish of the grinding.

The machining accuracy and efficiency of the double disc grinding machine are its two core advantages. Through the precise control system and automatic inspection system, the double disc grinding machine can monitor the size, shape and surface quality of the workpiece in real time to ensure the machining accuracy. At the same time, the design of simultaneous grinding of double faces greatly improves machining efficiency and reduces machining time.

In addition, the double disc grinder is equipped with a variety of auxiliary functions, such as spraying of coolant or lubricant, automatic feeding, automatic inspection, automatic adjustment and so on. These functions not only improve the stability and reliability of the machining process, but also further enhance productivity.

Overall, double disc grinding machine plays an important role in industrial production with its high precision and high efficiency. With the continuous progress of technology, the performance and accuracy of the grinding machines are also constantly improving. In the future, double disc grinding machines will continue to develop in the direction of more precision and intelligence, providing strong support for the transformation and upgrading of the manufacturing industry.

Understanding the basics of double disc grinding machine not only helps us to better select and use this machine tool, but also helps us to better understand and appreciate its important role in industrial production.
