Surface finish affects appearance, friction, sealing, assembly fit, and corrosion performance of CNC machined parts.
How it works
The drawing is reviewed first, then the suitable turning, milling, drilling, threading, or finishing process is selected. Material, tolerance, surface finish, and quantity all affect the production route.
Applications
- turned shafts
- connector faces
- sleeves
- precision mating components
- custom metal parts for industrial equipment
Why it matters for buyers
OEM buyers need clear communication before production. A realistic supplier should confirm manufacturability, tolerance risk, lead time, and inspection method before accepting an order.
Buyer note
If a specific Ra value is required, it should be shown on the drawing. General visual finish requirements should also be communicated before quotation.
