🔧 What This Machine Does Best (Plain English)

This machine was built for deep-hole work on cylindrical and square workpieces.
The bed is rigid – really rigid – so it holds accuracy over years of use.
It handles large parts without breaking a sweat.
The spindle covers a wide speed range, so you can run different deep-hole processes.
The feed system uses AC servo motors – smooth, accurate, and efficient.
The oil dispenser uses servo control to tighten the workpiece. No guessing, no slipping.

1.3.2 Clamping the Workpiece – Holds Like a Rock

One end goes into the chuck on the headstock.
The other end gets clamped by the cone disc on the oil pressure head.

That's two ends secured. Zero vibration. True concentricity.

1.3.3 Control System – FANUC, Plain and Simple

X‑axis – Tool expand and retract
Servo motor → servo reducer → ball screw → core rod moves axially

Z‑axis – Drill box moves forward and back
Servo motor drives ball screw directly

W‑axis – Oil pressure head servo clamping
Servo motor drives ball screw for precise tightening
