SLOW DOWN

SLOW JUMP

In non-Sodick die-sinking EDMs with inert and low-speed ball-screw drives, flushing is always a risk of FAILURE due to incomplete chips evacuation! The arrangement and method of flushing in each case depends on the shape of the electrode, the depth and direction of machining and cannot be standardised.

If the electrode is of a complex (complicated) shape, flushing does not solve the problem. If the operator is not a virtuoso and does not stop the process to redirect the nozzles, a DEFECT IS INEVITABLE!

Chip evacuation flaws lead to increased and uneven wear of the electrode, the occurence of short circuits, arc discharges, build-up on the electrode and the part, and slagging.

AS A RESULT – DEFECTS!

RAPID DOWN

RAPID JUMP

Linear servo drives in Sodick EDMs with powerful flat linear motors move the electrode at speeds up to 600 mm/s and accelerations up to 2.0G!

Dynamically and quickly moving up and down, the electrode works like a pump piston, evacuating electroerosion waste incomparably more efficiently than dielectric flushing!

Instead of dielectric flushing, the pumping effect of fast electrode movements is used! In other words, only relaxation (up-down reciprocation) movements and oscillations of the electrode itself are sufficient to wash out the chips for the first time.

Regardless of the experience of the operator, the complexity or depth of the work – always high-quality machining, EDMing without defects!
