Chips and pull outs on parts
1.Chips or pull outs of up to 0.5mm are cceptable but will be dressed if necessary, to avoid crack propagation.
2. Chips measuring 0.5mm – 1.0mm will be inspected and a concession will be requested from the customer.
3. Any parts with chips over 1.0mm will be rejected.
Sharp edges
Sharp edges will be dressed as necessary with a break edge, radius of up to 0.5mm.
surface Finish
Unless specified otherwise, the surface finish of all hard machined faces will be 0.8 µm Ra or better.
Cracks
All parts will be supplied free from cracks, parts will typically be inspected by the following methods:
1. Visual inspection
2. Light penetration: Bright light will be used to inspect parts for cracks.
Cracks can be identified by shining a light through the wall thickness of the part. We can also use a UV lamp for crack detection.
3. Dye penetration: A red dye will be used on parts where light penetration is not able to pick up cracks.
Standard tolerances
If there is no special requirement, we refer to DIN ISO 2768-mK for dimensional tolerances of our products. About positional tolerance, we will conform to 0.1mm positional tolerance unless otherwise specified.
