Main Components Description

1. Heavy Cast Iron Bed

Constructed from high-grade cast iron with resin sand casting process, followed by two aging treatments to eliminate internal stress. The internal V-shaped reinforced ribs ensure high rigidity and minimal deformation during heavy cutting. The outer wall directly supports the guideways, providing strong resistance to vibration and ensuring stable machining.

2. Headstock

Driven by a 37 kW servo spindle motor, with 3 manual gears and stepless speed regulation. Equipped with a Φ400mm manual three-jaw chuck for reliable workpiece clamping. Gears are precision ground and high-frequency quenched for high strength and wear resistance.

3. Drill Box

Installed on the feeding carriage, powered by a 37 kW servo spindle motor. It drives the cutting tool for drilling and boring operations. The spindle is equipped with a tool shank connection sleeve and a chips removal bucket for efficient chip discharge.

4. Oil Pressure Head (Support & Clamping Unit)

Servo motor-driven axial movement for adapting different workpiece lengths and automatic tightening. It features a guide sleeve, cone disc for positioning, and an oil shield with push-pull structure for coolant recovery.

5. Coolant & Chip Removal System

Large-capacity (3900L) floor-mounted oil tank with high-pressure (2.5MPa) and high-flow (400L/min) coolant supply. Ensures efficient cooling, lubrication, and chip removal during deep hole processing.

6. Control & Operation System

Standard configuration: DELTA PLC with user-friendly operation panel. Optional upgrade to Siemens or FANUC CNC system for full automatic cycle programming and multi-axis interpolation control.
