Precision Spindle

Precision spindle CNC machine tool technology is one of the core technology. The key technology is the precision spindle precision spindle bearing selection and installation techniques. China is now wholly-owned and joint venture CNC machine tool spindle, especially high-speed spindle, mostly imported products, even if the state-owned joint-stock companies, also spend a lot of foreign exchange to import precision spindle year.

Our country from the beginning of this century, a large number of high-speed application processing technology, which for the machine tool spindle proposed a more stringent technical requirements, to date, only the use of hydrodynamic bearings precision grinding machines, its rotation accuracy can be achieved in one-thousandth mm standard, even with international quality brand precision bearings, rolling bearing mounted spindle not yet reached the level of precision hydraulic slide bearings. Analyze the causes, the problem is not out of the bearing itself, mainly our face in processing and installation of bearings and bearing does not reach the precision of fit, including design unscientific mounting structure is a very important aspect. On such issues, this blog will serve as case studies, but also hope that the domestic counterparts valuable advice.
