Start an enquiry
Match the process to the geometry
Wire and spark erosion can be relevant where conventional tool access is limited or the component is already hardened. Suitability depends on material, geometry and the required surface condition; confirm the manufacturing route during technical review.
Treat finishing as part of the plan
Grinding, deburring and other finishing steps can affect the final dimensions and edge condition. Leave appropriate process allowances and identify surfaces that must remain protected. Any external processing should be included in the agreed route.
Close the loop with inspection
Identify which features are functionally important and how they will be verified after all operations are complete. A precise drawing and an agreed measurement approach make the acceptance decision clearer for both teams.
