The History of Grinder(2)
Before and after 1900, the development of man-made abrasive and application of the hydraulic transmission, play a great role in promoting the development of the grinder. With the modern industry in particular Automotive Industry, a variety of different types of grinders have come out in succession. For example, in the early 20th century, has developed planet-cylinder grinder with Cylinder-processing, crankshaft grinder, camshaft grinder and piston ring grinding machine with electromagnetic sucker and so on.
Automatic measuring device at the beginning of 1908 applied to the grinder. By around 1920, Grinder, double-face grinding machine, roll grinding machine, rail grinding machine, honing and super-finishing machine, and so on have been made use of; the 50s high-precision cylindrical grinding machine which carry out mirror grinding. come out; at the end of 60's there have been wheel-line speed of 60 to 80 m / s high-speed grinder and cut deep, creep feed grinding surface grinder ; 70 years, the digital microprocessor control and adaptive control technology have been a wide range of applications in the grinding machine.
the precision grinder with mirror grinding
With the the number of high precision and high hardness mechanical parts increase, as well as the development of precision casting and precision forging process, grinding performance, variety and output are continuing to improve and grow.
Grinder is most varieties of a class in all types of metal-cutting machine tools ,the main types have Cylindrical Grinder, internal grinder, surface grinder, centerless grinder, tool grinder so on.
