Straightness problems on a wire EDM?

Question

what is a common solution to straightness problems on a wire EDM

Answer 1

You should if possible try the spark method of checking for vertical, instead of the gizmo they give you with the machine. Make sure you check for vertical with every detail you cut right on that very same detail, also make sure you use low voltage settings( ie: low on time, high off time while doing your spark check.

Other factors may include, bad flushing nozzles, incorrect wire tension, or a host of others.

Look in your manuel, it should explain everything. If not then call the dealer where you bought the machine from.

Good luck.

Answer 2

It depends on what is causing it not to cut straight.  It could be wear in the XYZ mechanisms positioning the wire guides.  It could be the tension in the wire.  It could be the shape of the wire (if the wire is badly scratched or mis-shapen).  It could be the flood coolant (if it is not adequately removing the cut debris from the kerf).  It could be something in the material itself.
