CNC tolerance describes the acceptable dimensional variation between the drawing requirement and the finished machined part.
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
- tight tolerance shafts
- precision pins
- bushings
- mating parts
- 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.
Common tolerance note
A tolerance such as ±0.01mm may be possible for some features, but it depends on geometry, material, part size, and inspection method.
