The development direction of CNC carving and milling machine tool

Because of CNC carving and milling machine tool nc software need PC as control platform, and the numerical control software stepper motor output pulse frequency of 25 ~ 40 KHZ, aimed at professional CNC carving and milling machine tool processing efficiency is low and the shortage of the huge inconvenience mobile, can design a dedicated motion controller to replace the PC hardware, explain and processing code, while greatly improve efficiency, also increase the CNC carving and milling machine tool machine is compact and mobility. With CNC carving and milling machine is widely used in various industries, its toward networking intelligent control, automatic tool change, high speed engraving, multi-axis and flexible direction, so choosing design, the development direction of nc carving and milling machine tool, should be considered for CNC carving and milling machine tool room function extension and upgrade. In design, CNC engraving machine engraving head adopts two schemes, scheme 1 is directly USES the dc motor USES the taper coordinate installation of small precision chuck program, scheme 2 is using dc motor to drive the spindle assemble ER11 tool scheme, by contrast, plan 1 structure is simple, the precision of 0. 1 mm or so, suitable for carving nonmetallic material, can satisfy the precision is not high occasions, the use of low cost. As the cause of the low accuracy is mainly due to the dc motor output shaft, the axial and radial force generated by beating and motor shaft wear at the same time, can't maintain relatively high precision for long. Scheme 2 structure through the experiment, has great improve accuracy, satisfy the requirement of the design target, the disadvantage is the use of a dc motor noise is big, can use instead of brushless dc motor, relatively high cost.
