spark erosion / cnc wire cut edm / wire cut edm machine
X/Y/Z/U/V axis travel: 750 / 450 / 320 / 160 / 160 mm

(1) Features of the mechanism

A cast-iron rugged design and introduce FEM analysis on ribs’ allocation to achieve thermal balance.
To increase the distance between linear ball ways on the basement is the foundation stone of high precision.
Use C1-class ball screw.
Each axis uses an AC motor with high efficient dialog response.
Linear ball way use Swiss, or Japanese made with new technologies ball retailer, which decreases friction at 90% compared with the conventional type.
Worktable with heat treatment classes at HRC 50.
Low-arm use a low expansion cast-iron and water cycling in order to reduce thermal effect.
Lubrication by means of computer control and the machine can be oiling at good timing and quantity.
Float sensors on the work tank control automatically water level.

10. Standard water cooling system reduces temperature influencing on workpiece to increase

machining accuracy.
