Wire-EDM Cutting
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.
Finecut FAW300
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.
CONCLUSIONS
Already without considering the pre-piercing required for the W-EDM the operational time reduction is 87% based on using the Finecut system.
Finecut Advantages
- Quick CAD/CAM preparation
- Simple fixturing
- Piercing and cutting in one set up
- Good surface – no finishing operation required
