TS21 Series Petroleum Drill Collar Special Machine Tool

♦ Specifically designed for machining deep-hole workpieces.
♦ Primarily utilizes the BTA method for machining small-diameter deep-hole components.
♦ Particularly suitable for machining oil drill collars.

The most notable structural features of this machine tool are:

♦ Dual chuck clamping is employed on the front side of the workpiece, near the oil feeder end, while an annular center rest is used for clamping on the rear side.
♦ Hydraulic control is easily adopted for the tightening of the workpiece and the clamping of the oil feeder, ensuring safety, reliability, and convenient operation.
♦ The machine tool is equipped with a drill spindle box to accommodate different machining process requirements.
