TLS222B deep hole boring machine

Machine Tool Applications:

♦ This machine tool is a specialized machine designed for boring long and slender tubes.

Machining Process:

♦ It adopts a machining method where the workpiece is fixed, and the tool shank rotates while performing feeding motion.
♦ During boring, an oil feeder is used to supply cutting fluid, and the chips are discharged forward.
♦ The tool feed is controlled by an AC servo system to achieve stepless speed regulation.
♦ The headstock spindle utilizes multi-stage gear shifting, providing a wide range of spindle speeds.
♦ The oil feeder is secured, and the workpiece is clamped using mechanical locking devices.
