The double-end grinder is a high-efficiency surface processing machine tool that grinds two parallel end surfaces at the same time in one processing process. According to the structure, it can be divided into horizontal and vertical types. According to the feeding method, it can be divided into through-type, Rotary type, reciprocating type. Because the ground products have high precision and high production efficiency, they are widely used in many industries such as automobiles and motorcycles, bearings, and magnetic materials. Pistons, piston rings, valve gaskets, connecting rods, cross shafts, valve plates, shift forks, hydraulic pump blades, rotors, stators, compressor slides, bearing inner and outer rings and rollers in the automobile and motorcycle industry, magnets in the electronics industry Rings, magnetic steel sheets, graphite plates and other products made of various materials are suitable for processing.

As the wind vane of the industrial manufacturing industry, DMP Greater Bay Area Industrial Expo will bring more than 2,200 global exhibitors, over 40 keynote speeches, and thousands of new industry technologies. Moresuperhard has the honor to participate the four-day Industrial Expo will focus on new products, solutions and achievements in the transformation of manufacturing digitization and the integration of high-end equipment and digital intelligence.

Centerless grinding: the center hole of the workpiece does not need to be centered during the grinding process.

Factors affecting the surface roughness of grinding machine processing and its improvement measures:

1. Factors related to the grinding wheel
Mainly grinding wheel particle size, hardness and dressing of the grinding wheel.

The grinding process is the grinding wheel surface of the abrasive particles on the surface of the workpiece cutting, grooving and sliding rubbing of the integr

Cylindrical grinding machine is one of the most common machine tool series products in the field of machining, and it is generally used for processing various cylindrical, conical outer surfaces, as well as shaft shoulder end faces. From the product classification level, it can be divided into ordinary cylindrical grinding machine, universal cylindrical grinding machine, wide grinding wheel external grinding machine, end face external grinding machine, multi-wheel frame external grinding machine, multi-disc grinding wheel external grinding machine, cut type external grinding machine and special external grinding machine and other types.
