Application of double disc grinding machine in piston pin grinding

In modern industrial production, double disc grinding machine, as a kind of high-efficiency and high-precision surface processing machine tool, is widely used in many industries such as automobile and motorbike, bearing, magnetic material and so on. And in these applications, the grinding of piston pins is one of the important links.

The working principle of double endface grinding machine is to grind two parallel endfaces at the same time through a single machining process, which is designed not only to improve the production efficiency, but also to ensure the accuracy of the product. This kind of machine tool can be divided into horizontal and vertical according to its structure, and can be divided into penetrating type, rotary type and reciprocating type according to the feeding method, and the flexible and various designs meet the processing needs of different materials and shapes of workpieces.

Piston pin is a key component in automobile engine, usually installed in the skirt of the piston, the middle of which passes through the small head hole of the connecting rod, connecting the piston and the connecting rod, and plays an important role in transmitting the gas force borne by the piston to the connecting rod. Because the piston pin needs to withstand a great deal of cyclical impact load when working, and the lubrication conditions are poor, so the piston pin is required to have sufficient stiffness, strength and wear resistance. At the same time, in order to reduce the weight, the piston pin is generally made of high-quality alloy steel, and made into a hollow. These characteristics make the machining of piston pins extremely demanding, and double disc grinding machines are ideal for meeting these requirements.

During the grinding process of the piston pin, the grinding machine ensures the high precision and parallelism of the two parallel end faces of the piston pin through a precise grinding process. This not only improves the quality of the piston pin, but also extends its service life. At the same time, the efficient production of double disc grinding machine also meets the demand of modern industry for mass production.

It is worth mentioning that with the progress of science and technology and the rapid development of industrial production, double disc grinding machines are also constantly improved and perfected. Modern double disc grinding machines not only have higher machining accuracy and efficiency, but also equipped with advanced CNC operating system and automatic loading device, further improving production efficiency and product quality. These improvements make the equipment more competent in the grinding process of piston pins.

In addition, the scope of application of the double disc grinding machine is not limited to the grinding of piston pins. It can also be used to machine piston rings, valve gaskets, connecting rods, cross shafts, valve blades, forks, hydraulic pump blades, rotors, stators, compressor slides, bearing inner and outer rings, and rollers in a wide range of materials. These products are widely used in automobile and motorbike, bearing, magnetic materials and other industries, and the efficient processing of it provides strong support for the development of these industries.

To sum up, double disc grinding machine plays a vital role in the grinding process of piston pins. Its high precision, high efficiency and wide range of applications make it an indispensable and important equipment in modern industrial production. With the continuous progress of science and technology and the continuous development of industrial production, double disc grinding machine will play a more important role in the future industrial production.
