This machine is a deep hole processing machine that can complete the drilling, boring and trepanning of large-diameter heavy parts. During processing, the workpiece rotates at a low speed, and the tool rotates and feeds at a high speed. When drilling, the BTA internal chip removal process is adopted, and when boring, the cutting fluid is supplied from the boring bar to discharge the cutting fluid forward (head end) to remove the chips.
