The Reasons and Solutions of the Bad Roughness During the Finish Cutting

1. The relative offset is too small-- increase it suitably.

2. The deformation leading to the finish cutting speed is not same--- try to control the deformation.

3. The EDM wire quality is bad—we suggest you change the good brand EDM wire.

5. The wire guiding parts are dirty—try to clean these parts.

6. The power feed contacts wear off too much—try rotate or change them.

7. Wrong machining parameters- select the right TEC.

8. The coolant condition is not good, like water pressure is weak, or water share is bad—check the upper and down water nozzles are broken or not.

9. Unstable wire running condition – please check the wire running system and adjust the pulleys.

Hope above information is helpful to you. For any more information about solutions of the wire EDM machines, please feel free to contact us.
