● The workpiece rotates at low speed during processing, and the tool rotates and feeds at high speed. ● Drilling process adopts BTA internal chip removal technology. ● When boring, the cutting fluid is supplied from the boring bar to the front (head end of the bed) to discharge the cutting fluid and remove the chips. ● The nesting adopts the process of external chip removal, and it needs to be equipped with special nesting tools, tool holders and special fixtures. ● According to processing needs, the machine tool is equipped with a drilling (boring) rod box, and the tool can be rotated and fed.
