Key Highlights

Heavy Cutting Capacity: G800 handles 1.2-ton workpieces (e.g., engine blocks) in a single setup.

Multi-Material Compatibility: Processes 8+ materials, including carbon steel, titanium, and cast iron.

5-Axis Precision: Achieves ±0.015mm accuracy for impellers, with surface finish up to Ra1.6μm.

Customer Profile

A heavy equipment manufacturer serving new energy vehicle and aerospace sectors faced critical challenges:

1.Engine Block Machining: Required 3 setups (cumulative error >0.1mm).

2.Titanium Impellers: 6.5-hour cycle time, 45% tooling cost.

3.Complex Parts: 4+ hours for planetary gearbox setup changes.

Solution: Deployed G630/G800 dual production line for flexible heavy-part machining.

Challenges

Challenge Category	Specific Pain Points
Machining Accuracy	Traditional equipment required multiple repositioning, causing 0.08mm cylinder bore misalignment.
Hard-to-Machine Materials	TC4 titanium impellers generated >800°C cutting heat, leading to 35% abnormal tool wear.
Complex Surfaces	Flow channel R-angles <3mm caused vibration marks, reducing aerodynamic efficiency by 12%.
Rapid Changeover	Switching from carbon steel hubs to aluminum frames required full fixture replacement, losing 3.2 man-hours daily.

Solutions

1.Heavy-Duty Machining Package

G800 Configuration:

Ø160mm face mill

50kW high-torque spindle

Results:

3x faster wheel hub face machining

8,000mm/min feed rate for cast iron

Engine blocks completed in single setup.

2.Special Process Breakthroughs

Titanium Impellers:

7MPa high-pressure coolant suppressed heat.

Trochoidal milling extended tool life 200%.

Planetary Gear Deep Cavities:

Custom damped boring bars enabled single-pass machining.

3.Smart Production System

Material-Adaptive Modes:

Carbon steel: Aggressive roughing (2,000rpm, 1.2mm depth).

Aluminum: High-speed finishing (15,000rpm, 0.05mm depth).

RFID Quick-Change: Reduced setup time to 25 minutes.

Customer Benefits

Metric	Improvement	Business Value
Efficiency	Large-part cycle time reduced by 70%	Engine output increased from 15→40 units/month.
Quality	Impeller profile accuracy ≤0.03mm	99.3% aerodynamic efficiency compliance.
Cost Savings	Titanium part costs down 38%	Annual savings: ¥1.8M.
