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.

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.

With the continuous development of industrial automation, intelligence and flexibility, robotics is widely used in the field of automotive parts manufacturing and processing, such as engine block, cylinder head, wheel hubs, luggage racks, interior trim, battery cover bottom bracket and so on.

Electrical spindle is in the field of CNC machine tools will appear in the machine tool spindle and spindle motor into one of the new skills, electrical spindle it with linear motor skills, high-speed tooling skills together, high-speed machining for a new era.
