CHMER Wire-Cut EDM Operation Manual W5F
19.
Avoiding water splash on floor at any time, that has potential dangers people
fall down or get electric shock.
20. The light from the work-lamp could generate high heat on the items
illuminated. Please be aware and keep fusible material such as plastic
cables away from being irradiated by work-lamp.
Safe operation and place for the personnel
1. Get rid of metal chips, water or oil is onto around the machine.
2. Operator puts on safe glasses and safe shoes.
3. When move in/ move out the work piece from working table, watch out the
fall down risk.
Checking points for safe dielectric cutting
1.Ensure work piece is fixed well by proper jigs and fixture ways on working
table.
2.Wire electrode is loading and traveling well by instructions.
3. Electrode cables / ground lines
a. Are they screwed properly
？
b. Cable coating in good conditions without any split
？
c. Upper/ lower nozzle distances are adjusted well won’t crash to each
other
Precaution of the use of stainless steel
1.The improper way of material conservation will shorten its life span.
Stainless steel tends to erode more rapidly after in touch with other materials.
2. The rust from other material could be passed to stainless steel if not properly
stored.
Checking points before cutting
1.Dielectric level is set properly (Submerged model)
？
2. Is dielectric level dropping down accidentally
？
3. Is work tank locked properly (submerge type)
？
.
4. Is Rubber Seal of tank door damaged
？
Checking points while cutting
1. Make sure no leakage of dielectric.
2. Upper/Lower flush pressure were adjusted to be coincident
？
