The double end grinding machine is a highly efficient surface machining machine.
Two parallel end faces are ground simultaneously in one machining process.
According to the structure, it can be divided into horizontal and vertical double end grinding machine.
According to the feeding method, it can be divided into a through type, a rotary type, and a reciprocating type.
Due to the high precision and high production efficiency of the products, the products are widely used in many industries such as automobile and motorcycle, bearings and magnetic materials.
Various materials like piston pins, piston rings, valve gaskets, connecting rods, cross shafts, valve plates, shift forks, hydraulic pump blades, rotors, stators, compressor slides, bearing inner rings and rollers, magnetic rings in the electronics industry, magnetic steel sheets, graphite sheets are suitable for processing.
Double end grinding machine origin
China’s double-face grinders, when the former Soviet Union technology supported China in the 1950s, produced double-end grinders of both horizontal and vertical structures, dedicated to the grinding of piston rings.
Then, according to the characteristics of the bearing rings, Chinese researchers have developed double-end grinding machines for grinding bearings, but the grinding machines of different manufacturers have different constructions and different characteristics.
At this time, the double-face grinding machine has developed rapidly in the bearing industry.
In the 1990s, China’s economic development entered the fast lane, and developed a high-precision CNC operating system grinding machine, such as MK7650\MKY7660\MK7675, which enabled the original double-face grinding machine to be improved in terms of variety and processing accuracy.
Double end grinding machine description
Entering this century, with the rapid development of China’s machinery industry, many imported parts and components have also been replaced by China’s own research and development, such as oil pump blades, compressor slides and other high-precision automotive parts.
Can also be widely used in double-end grinding machine processing.
In particular, the size of the sliding plate grinding by the cubic boron nitride grinding wheel ensures the technical requirements of coarse grinding of the product, the parallel difference is ≤0.005, the flatness is ≤0.003, and the verticality is ≤0.02.
The automatic feeding device is equipped to improve the production efficiency, and the production capacity is more than 70,000 pieces, which ensures the consistency of the product size requirements and has been adopted by many customers.
