Product description

Parameters

Machine tool usage:

♦Drilling, boring and nesting processing of large diameter and heavy parts can be completed.

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.
