Machine tool usage:
♦ Specialized in processing deep hole workpieces.
♦ Mainly using BTA method to process small diameter deep hole parts.
♦ Especially suitable for processing petroleum drill collars.
The biggest structural feature of this machine tool is:
♦ The front side of the workpiece is clamped with double chucks near the oil feeder end, and the rear side is clamped with an annular center frame.
♦ The clamping of the workpiece and the oil feeder is easily controlled by hydraulic pressure, which is safe, reliable, and easy to operate.
♦ This machine tool is equipped with a drill pipe box to adapt to different machining process requirements.
