In this case we have compared the Finecut system with W-EDM for 1 millimeter shims.
|Data for comparison|
|Dimensions||301 mm x 169 mm|
|Detail cutting distance||3 351 mm|
|Tolerance requirement||±0.02 mm|
Cutting 10 sheets at the same time takes 1 hour 53 min for piercing and contour cutting with wire-EDM cutting. Hole making in separate machine, i.e. two set-ups.
Erosion based cutting with a cut width of 0.3 mm. No heat impact. Hole piercing is done automatically.
Feed rate of maximum of 469 mm/min and minimum 182 mm/min in the corners gives a total cutting time, including piercing time, of 9 minutes and 52 seconds. With the Finecut system the surfaces does not require any after treatment.
The price for individual details with an operating cost of 15 Eur/h is 2.47 EUR/component.
Already without considering the pre-piercing required for the W-EDM the operational time reduction is 87% based on using the Finecut system.
