Winberg’s own in-house 8 step micro polish is a fully mechanical polish – there is no chemical etching of the part. Processed and developed by Winberg Crankshafts, this polish is unique from all other polishing processes available for crankshafts.
By developing this process themselves, they are able to maintain a finish finer than any other process on the market, based on in house testing of major critical surfaces. Testing of critical ground surfaces yielded an average of less than 1 Ra; equivalent to 0.020 µm of variation. The results are reduced parasitic losses, reduced oil foaming and increased oil shedding.
