How to use inverter to better use the internal machine tools?
At present, the inverter has a high price retio, therefore, the inverter is widely used in NC transformation of economical CNC and general internal grinding machine tools, and has these advantages: 1st, convenient debugging, 2nd, simplify the control line, 3rd, use frequency converter to change the cutting speed.
Most of the economic CNC Internal grinding can not automatically change the speed, when the speed need to be changed, we can only stop the machine, and then change manually. The main transmission system of the Multi-function CNC Internal grinding machine tools mostly adopts stepless speed regulation. At present, there are mainly two kinds of spindles, they’re variable speed spindle system and servo spindle system., usually adopt DC or AC spindle motor. The main shaft is rotated by a belt drive, or be driven through a reduction gear from the belt and the main shaft box (to obtain greater torque). Because of the wide range of spindle motor speed regulation and stepless speed regulation, the structure of the spindle box is greatly simplified. At present, due to the high cost performance of the inverters, there is very common usage in internal grinding machine tools.
