Overview

The GF Machining Solutions AgieCharmilles CUT S 400 is the compact model in the CUT S performance series — GF's mid-to-upper tier wire EDM platform delivering Ra 0.08 micrometers surface finish capability with the UNIQUA HMI control. With X/Y/Z travels of 405 x 315 x 256 mm and U/V travel of 500 x 350 mm, the CUT S 400 offers a slightly larger cutting envelope than the CUT X 350 at a more accessible price point.

The CUT S 400 supports wire diameters from 0.05 to 0.30 mm (0.20 or 0.25 mm standard), giving it exceptional versatility from micro-detail work with ultra-fine wire to production cutting with standard brass wire. The 0.05 mm minimum wire capability is finer than most competitor machines and enables internal corner radii approaching 0.03 mm for micro-feature applications.

Maximum workpiece weight capacity of 1,000 kg significantly exceeds the CUT X 350's 450 kg limit, making the CUT S 400 well suited for heavy die blocks and mold bases. Taper angle capability of +/-30 degrees over 256 mm height, with optional 45-degree capability, handles aggressive taper requirements for stamping dies and extrusion tooling.

The UNIQUA control provides the same modern touchscreen interface as the CUT X series with integrated technology databases and automatic parameter selection. While the CUT S 400 lacks the CUT X's real-time AI discharge optimization, it delivers the same Ra 0.08 micrometers best surface finish through GF's proven multi-pass skim cut technology — making it the value choice for shops that need top-tier finish without the AI premium.

Strengths & Limitations

Strengths

Ra 0.08 micrometers surface finish matches the CUT X series at a lower price point
1,000 kg workpiece weight capacity handles heavy die blocks and mold bases
Ultra-fine 0.05 mm wire capability enables micro-feature cutting with corner radii approaching 0.03 mm
UNIQUA HMI provides modern touchscreen control with integrated technology databases
+/-30 deg taper with optional 45 deg covers aggressive taper requirements for stamping dies
405 x 315 mm X/Y travel slightly exceeds the CUT X 350 envelope

Limitations

Lacks the CUT X AI-driven real-time discharge optimization for variable-geometry cutting
Heavier 1,000 kg capacity comes with larger machine footprint than entry-level wire EDMs
0.05 mm wire option adds cost and requires careful setup and wire handling
Premium pricing relative to entry-level CUT E series for shops with simpler requirements

Best For

Die and mold shops requiring Ra 0.08 micrometers finish without the CUT X AI premium Shops cutting heavy die blocks up to 1,000 kg that exceed CUT X 350 weight limits Micro-feature applications requiring 0.05 mm wire for ultra-fine internal radii Production wire EDM departments needing the UNIQUA control with proven technology databases Stamping die shops requiring +/-30 deg or 45 deg taper capability

Frequently Asked Questions

01 How does the CUT S 400 compare to the CUT X 350?

The CUT S 400 offers larger X/Y travel (405x315 vs 350x250 mm), higher workpiece weight (1,000 vs 450 kg), and finer minimum wire (0.05 vs 0.07 mm) at a lower price point. The CUT X 350 adds AI-driven real-time discharge optimization for more consistent finish on complex profiles. Both achieve Ra 0.08 micrometers and use the UNIQUA HMI.

02 What is the finest wire the CUT S 400 can run?

With the optional fine-wire package, the CUT S 400 supports wire diameters down to 0.05 mm — finer than the CUT X 350 minimum of 0.07 mm. At 0.05 mm, internal corner radii approach 0.03 mm, enabling micro-detail cutting for watchmaking, medical device, and precision electronics applications.

03 Can the CUT S 400 achieve 45-degree taper?

Yes, with the optional 45-degree taper package. Standard capability is +/-30 degrees over 256 mm Z height. The 45-degree option is typically selected for stamping die clearance angles, extrusion die tapers, and other applications requiring aggressive angular features.

04 What surface finish quality can the CUT S 400 achieve?

The CUT S 400 achieves Ra 0.08 micrometers best surface finish using multi-pass skim cut technology — the same finish specification as the CUT X series. Achieving this requires clean dielectric, appropriate wire type, and 3-5 skim passes after the main cut.
