Model Selection Guidance
The DK77120 provides 1200 × 1600 mm X/Y travel, a 4500 kg table-load limit and a listed maximum workpiece thickness of 900 mm. Compare the DK77100 for a smaller 1000 × 1200 mm envelope, or the DK77160 for 1600 × 2000 mm travel and a 6000 kg table load. See all single-cut wire EDM machines.
Information Required for a Technical Quote
Please send the workpiece material, maximum X/Y dimensions, thickness and weight; target tolerance and surface roughness; required power supply and destination country; and any preferred control system or automation requirement.
