【Abstract】 A new type high speed precision grinder is designed and manufactured with PMAC (Programmable Multi-axis Controller) -PC Open NC system as its central controller. The servo control technology of linear motor and design and manufacture of electric spindle units are discussed. The dynamic performance of the whole machine is analyzed based on the high speed grinding experiments. Elliptical workpieces have been machined on this new type high speed precision grinder, thus providing solutions to precision machining of non-circular cross section workpieces and promoting the development of high speed grinding technology.更多还原
