In order to ensure the main axle39。s localization checking device should be installed. In this way, making use of the electrical main axle39。s accurate localization is to be realized, As soon as the numerical control system sends the instruction signals. The frequency conversion and alternating current motor is substituted with step less speed regulation to the main drive. Rotation speed of lower grade is 1583r/min and higher grade834500r/min.Step less speed regulation can be realized within all the grades. Compared to the mechanical structure of the original upright milling Machine, it is suppleness, because the function of speed conversion is taken mainly or all by main axle motor39。s speed conversion structure. The main drive system is a system of alternating current and frequency conversion controlled by open loop, whose speed regulation is done by software. The numerical system is a data control system designed by model block based on single chip microputer The single chip microputer of smaller volume is adopted to realize the plicated logical function, Making full use of the interrupt and the second functional entrance to make the usage of the entrance to the highest degree and the whole structure easier. As a whole, the system can be divided into manmachine interface model block, the serial munication model block, the hydraulic system, the cooling system, the lubrication system and the main control model block based on the 89C58 single chip microputer. Overing the traditional economy numerical control system39。 through the keyboard and the display model, it has realized the procedure edition and the display。s design, it has realized the machine function39。國際市場的競爭歸根到底是各國制造生產(chǎn)能力及機械制造裝備的競爭。目前,國內(nèi)、外數(shù)控機床正
