GF AGIE CHARMILLES Wire Cut mod. CUT20

year: 2009

Technical Specifications: EDM wire cutting uses a metallic wire (electrode) to cut a programmed contour in a workpiece. Extrusion dies and blanking punches are very often machined by wire cutting. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode). The wire can be inclined, thus making it possible to make parts with taper or with different profiles at the top and bottom. The wire is usually made of brass or stratified copper, and is between 0.02 and 0.33 mm diameter. Travel on X axis 350 mm Travel on Y axis 250 mm Travel on Z axis 250 mm Travel on U axis 90 mm Travel on V axis 90 mm Taper angle/heigh ±25°/80 Workpiece dimensions (Length x Width x Height) 900 x 680 x 250 mm Max. workpiece weight (without bath) 400 Kg Volume of dielectric 400 l Available wire diameters (Standard) 0.30-0.15mm Best surface finish (Standard) <0.25µm

 

GF AGIE CHARMILLES Die Sinking mod. FORM20

year: 2009

Technical Specifications: EDM die sinking reproduces, in a metallic workpiece, the shape of a tool called electrode. The shape given to the electrode is that of the object that is going to be molded. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode). There is never any mechanical contact between the electrode and workpiece. The electrode is usually made of copper or graphite. Travel on X axis 350 mm Travel on Y axis 250 mm Travel on Z axis 250 mm Travel on U axis 90 mm Travel on V axis 90 mm Movement measurement system resolution 0.5µm Worktank size (Width x Depth x Height) 955 x 540 x 350 mm Worktable size (Width x Depth) 630 x 400 mm Max. electrode weight 50 Kg Max. workpiece weight 200 Kg Max. workpiece size (Width x Depth x Height) 800 x 500 x 265 mm Min./Max. distance between table and chuck 230/480 mm Dielectric System: Filter type 2 built in paper cartridges with a reservoir capacity of 270 l Generator type APG FORM Standard machining current 72 A Best surface finish Ra copper-steel 0.2 µm
