Advantages
Sodick ALC400G Premium
- Tighter positioning accuracy at 0.001 mm (0.00004 in) for precision-critical work
- Superior max taper angle at 30° (at 100 mm thickness) vs +/-25° at 130 mm height
- Backed by Sodick's dealer and service network for parts and support
- Precision mold and die shops cutting tool steel, carbide, and PCD components where sub-micron surface finish eliminates hand polishing and directly impacts mold quality
Sodick ALC600G
- Greater x travel of 600 mm (23.62 in) accommodates larger workpieces
- Greater y travel of 400 mm (15.75 in) accommodates larger workpieces
- Greater z travel of 350 mm (13.78 in) accommodates larger workpieces
- Superior max workpiece weight at 1,000 kg (2,205 lb) vs 500 kg (1,102 lb)
- Superior surface finish at Ra 0.20 um (8 uin Ra) vs Ra 0.08 µm (multi-pass)
Verdict
The Sodick ALC600G edges ahead on specifications in this comparison, particularly in X Travel and Y Travel. However, the Sodick ALC400G Premium remains competitive and may be the better choice depending on price, dealer support in your area, or specific workholding and tooling considerations. Both are capable machines — the best decision comes from running your actual parts and evaluating total cost of ownership including tooling, training, and service.
