What material thickness or size range suits CNC Surface Grinding P20 Mold Steel?
We machine P20 Mold Steel across a broad size range; share your part envelope for confirmation.
What is the typical lead time and minimum order for CNC Surface Grinding P20 Mold Steel?
CNC Surface Grinding prototypes for P20 Mold Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Surface Grinding P20 Mold Steel?
Achievable tolerances for P20 Mold Steel grinding depend on the alloy, geometry and feature size. Grinding routinely holds single-micron tolerances on diameter, flatness and parallelism. Exact figures are confirmed against your drawing callouts.
How clean are the edges produced by CNC Surface Grinding on P20 Mold Steel?
Machined P20 Mold Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on P20 Mold Steel with CNC Surface Grinding?
Grinding can take P20 Mold Steel to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
