We can polish manually or mechanically up to values < 0.2 Ra or to achieve mirror finish quality.
Mechanical Polishing. For this we have 2 machines that are complementary to each other. Depending on the processing, the process takes 4 to 20 hours. This is a dimensionally stable operation.
Manual Polishing. We have several employees with golden hands who can polish what the machines can’t. e.g. holes Ø<3mm.
Diametal only uses grinding and polishing pastes without animal products. Our process water is filtered and reused.
