BTA Deep Hole Drilling Machine

BTA deep hole drilling machines are specialized machines designed for large-diameter deep hole drilling and deep hole machining. BTA machines can create extremely deep and precise holes in a wide range of materials. Microdrilling BTA deep hole drilling machines integrate advanced technologies, including tool support, coolant pressure, and machine power, to precisely and efficiently handle deep hole drilling applications.

The BTA deep hole drilling machine series offers two options: the WR type and the TR type. The configuration is usually based on the size and shape of the workpiece, desired production rate, and accuracy specifications. During the drilling process, the chips are flushed out through the center of the BTA tool and then discharged through the drill tube and machine spindle, eliminating the need for interrupted feed or segmented drilling to remove chips. This greatly improves production efficiency.

Model: WR-120 x 3000 (Workpiece rotation)
