In order to satisfy market demand and scientific skills, in order to reach the modern skills of numerical control skills in high demand, NC continues to open in the future, based on the sixth-generation PC, high speed and high precision, intelligent direction.
CNC engraving and milling machine is a polishing and milling to CNC machine tool, its primary feature is the use of small tools and high-speed electric spindles forengraving and milling processing. Meanwhile, spindle speed usually in the 20000~60000r/min of the job, up to a maximum of 100000r/min per cent, spindle workwhile running at no load and demand should be steady, speed error is necessary to ensure that the practice is less than 10. In the course of work of electric spindlebearing temperature and temperature rise should be at a lower plan; reverse accuracy, low speed is usually around 2m, 20000r/min or more often 10m. CNC engraving and milling machine is mainly used for processing of small commodities, in thepractice of electric spindle on machining cutting load, CNC engraving and milling electric spindle power is small, usually just a few kilowatts, to be much simpler thanthe BT40 spindle of high speed. Perfectly satisfied with high speed and high precision machining needs.

Motorized spindle for CNC engraving and milling machine, but also for processing intermediate support spindle and lay a solid foundation. Prepared for processing spindle made in supporting good enough conditions. The future, strong skills, quality reliable, high brand awareness of electric spindle manufacturers in machine tool profession make broad space.
