What surface finish is achievable on P20 Mold Steel with CNC Boring?
Surface finish on P20 Mold Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What is CNC Boring P20 Mold Steel and how is it done?
CNC Boring P20 Mold Steel refers to boring enlarges and finishes existing holes to precise diameter, roundness and surface finish. Applied to P20 Mold Steel — mold-grade, polishable and hardenable — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What material thickness or size range suits CNC Boring P20 Mold Steel?
Turned P20 Mold Steel parts are produced from bar or chuck stock across a wide diameter range.
How clean are the edges produced by CNC Boring 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.
