Combined with special servo driver and optimal control scheme, rare earth permanent magnet synchronous spindle and spindle motor’s excellent magnetic synchronous features will improve the processing efficiency to more than two times of domestic market mainstream miniature vertical machining center and drilling and milling center. Vertical machining center and drilling and milling center that using rare earth permanent magnet synchronous spindle and rare earth permanent magnet synchronous high - speed liquid - cooled spindle motor have combined drilling and milling center and CNC engraving and milling machine together, which has become a high-speed and efficient application scheme that integrates milling, engraving, tapping, grinding, drilling, boring, countersinking, reaming and expanding together.
● Less drive error
The main drive chain of machine tool is zero, and motor directly drives the spindle without any drive error, which has significantly decreased the spindle vibration and improved the workpiece surface roughness.
● Large power ratio and constant torque range, high response speed
The motor is rare earth permanent magnet synchronic motor with high power density and torque density;
Compared with the asynchronous motor, synchronic motor has extremely high response speed, large power density and constant torque range. And it’s a power level greater than asynchronous motor in the same volume.
● Built-in direct drive design, flexible power configuration
The motor is inside the spindle, the motor power can arbitrarily match spindle in thickness and length with a flexible constitution, meeting various spindle radial space limit applications;
● Wide speed regulation range
The motor can realize a very wide speed regulation range, and the stepless speed regulation can be realized from zero speed to the maximum speed;
● High productivity
The motor has excellent low-speed hard characteristics. under the permit of bearing rigidity and cutting tool hardness, it can carry out hard metal cutting with low-speed large engagement, or precision cutting with high-speed small engagement, which has greatly improved the production efficiency;
● High servo
All functions of digital servo spindle can be realized with special-purpose driver, such as: rigid tapping, quasi-stop positioning and motion control function, etc.
● Support flange, base installation method
