TS21100/TS21100G/TS21160 heavy-duty deep hole drilling and boring machine
Processing technology
● 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.
