Lining

This is usually caused by setting error in POS 1 – 2 and 3.

1. Verify the correct stock removal of the metal wheels, verify the stock removal from the polish wheels
2. Reduce the Feedrate for POS 3 and/or POS 4 to around 25% of the value

Orange Peel Effect

This is usually caused by excessive pressure applied to the polishing tools, POS 4 - 6. It can also be caused by heterogeneous material which have different elements inside with varying degrees of hardness.

1. Reduce the pressure of POS 4 by decreasing the stock removal value to the minimum setting
2. Increase feed rate up to 1500mm/min
3. Reduce stock removal setting to minimum on POS 5
4. Use POS 6 as normal

Insufficient Polish Quality

This is usually caused by an issue with the setting of the polishing tools, POS 4 - 6.

1. Increase stock removal to 0.05mm on POS 6 and /or reduce the Feedrate for POS 6 (and eventually on all polishers)

Please be aware that increasing the pressure of the polishing tools will apply more polish, but will decrease their lifespan.
