CNC carving and milling machine tool main movement scheme usually has two kinds:
1, adopt numerical control carving and milling machine tool spindle motor, the main use of motorized spindle is high frequency motor, communication is also called & quot; The high frequency spindle & quot; , with no intermediate transmission link, sometimes called it & quot; Direct drive spindle & quot; 。 Motorized spindle can be constant power or constant torque output, radial precision of 0 & quot; 01 ~ 0' ” 001 mm, the axial accuracy is less than 0 & quot; 003mm; Has a compact structure, light weight, small inertia, small vibration, low noise, and the advantages of fast response, and high speed, big power, simplify nc carving and milling machine tool design, easy to implement the spindle positioning, is an ideal structure of high speed spindle unit & quot; Motorized spindle defect is must with frequency inverter speed control device, the overall price expensive & quot;
2, USES the dc motor to drive the spindle organization. First, dc motor, wide speed range and the rotor speed can be adjusted in a range of continuous and stable operation, features a linear. Both mechanical properties and regulating characteristics are good linearity. Second, the dc motor price is very cheap, is especially suitable for economical engraving machine. Defect is low precision machine, mainly radial error is big, the general dc motor in high speed when the noise is big, and carbon brush wear easily, choose suitable bearing can improve the motor shaft radial accuracy and reduce the noise.
compared with CNC carving and milling machine boring spindle motor, dc motor drives the spindle organization scheme has higher cost performance, so the priority choose plan of dc motor to drive the spindle organization.
