Overview

The Sodick AL400G i Groove+ Edition is the standard-tier linear motor wire EDM in the 400mm X-travel class, offering 400 x 300 x 250 mm (15.75 x 11.81 x 9.84 in) X/Y/Z travel with a 500 kg (1,102 lb) flushing workpiece capacity. The AL400G shares the same rigid machine platform and four-axis linear motor drive system as the premium AL400P, but uses the Digital HF control generator rather than the Smart Pulse unit.

The four-axis linear motor drive system on X, Y, U, and V axes is identical to the premium AL400P. High-performance linear motors provide zero-backlash, frictionless positioning with no mechanical wear path. Glass scale feedback on all axes delivers closed-loop positioning. The 10-year positioning accuracy guarantee applies equally.

The Digital HF control delivers excellent surface finish quality and reliable cutting performance across materials and thicknesses. For many shops, the speed difference between the G and P generators is minutes per part.

The i Groove+ corner control and taper compensation system is standard. The +/-25 degree taper capability, 150 x 150 mm U/V travel, and 0.05-0.30 mm wire diameter range are identical to the AL400P.

Pricing typically falls in the USD 95,000-140,000 range, representing meaningful savings over the AL400P.

Strengths & Limitations

Strengths

Linear motor drives deliver same zero-backlash accuracy as the premium AL400P, backed by 10-year positioning guarantee
i Groove+ corner control is standard with no compromise on accuracy versus premium models
Lower entry price provides full linear motor accuracy at a more accessible price point
Digital HF control delivers reliable cutting performance across standard materials
Three-sided rise/fall work tank provides fast workpiece loading access
Wire diameter range from 0.05 to 0.30 mm covers fine detail and standard production

Limitations

Digital HF generator does not match Smart Pulse peak cutting speeds
Z-axis travel limited to 250 mm for shops cutting tall parts
North American dealer network smaller than Mitsubishi MC Machinery in some regions
Control interface not as modern as latest touchscreen HMIs from GF or Mitsubishi

Best For

Job shops needing reliable linear motor accuracy without paying for the fastest generator Mold and die shops where long-term accuracy retention is the primary purchase driver Shops upgrading from older ball-screw wire EDMs wanting linear motor advantages Progressive die work where i Groove+ corner accuracy is critical Budget-conscious operations where lower acquisition cost provides better TCO

Frequently Asked Questions

01 Difference between AL400G and AL400P?

The AL400G uses the standard Digital HF generator, the AL400P has Smart Pulse for faster cutting. Both share identical linear motor drives, i Groove+, travel, and capacity.

02 Accurate enough for precision mold work?

Yes. Same four-axis linear motor system and glass scales as the AL400P. Positioning accuracy is identical with the same 10-year guarantee.

03 Digital HF vs Smart Pulse?

Digital HF delivers reliable performance. Smart Pulse provides 10-20% faster roughing and improved multi-pass consistency.

04 Linear motor maintenance?

Essentially maintenance-free. No ball screws, no way guides, no wear components. Standard maintenance is dielectric fluid, wire guides, and power feed contacts.
