CNC Grinding Parts
CNC grinding applies computer numerical control to a process that was historically dependent on operator skill. It is used as a finishing operation where a machined part needs closer tolerance, a better surface finish or a hardened surface brought back to size after heat treatment.
Product Overview
CNC grinding applies computer numerical control to a process that was historically dependent on operator skill. It is used as a finishing operation where a machined part needs closer tolerance, a better surface finish or a hardened surface brought back to size after heat treatment. Parts are ground to the customer drawing, including intricate grinding work that is difficult to carry out manually.
Key Benefits
- Closer tolerance and better surface finish than machining alone can give
- Hardened parts brought back to size after heat treatment
- Computer control makes results repeatable rather than operator dependent
- Intricate grinding tasks handled that manual grinding cannot hold
- Supplied as a finishing stage alongside turning and milling
Problems It Solves
- Surface finish not good enough for a seal or bearing to run against
- Hardened parts out of tolerance after heat treatment
- Manual grinding results that vary between operators and batches
- Tolerances that turning and milling alone cannot reach
Where It Is Used
Applications And Buyers
Application Scenarios
- Finishing bearing journals and seal diameters on shafts
- Sizing hardened components after heat treatment
- Producing flat and parallel faces on tooling
- Correcting distortion introduced during hardening
Who It Is For
- Machine builders with parts running in bearings or seals
- Tool and die makers
- Manufacturers of hardened wear components
- Buyers whose current supplier cannot hold the finish specified

How It Is Made And Checked
Materials Process And Quality Control
Manufacturing Process
- CNC grinding
- Turning
- Milling
- Heat treatment
Quality Control
- Specification agreed in writing before production starts
- First article or sample approved against the agreed specification
- Goods inspected and photographed at the factory before loading
- Inspection report sent to you before the container sails
Customisation Options
What Can Be Varied
- Ground features and tolerances specified per drawing
- Surface finish specified where it matters
- Grinding after heat treatment where the part needs it
- Material free issued by you or supplied by us
- Single parts or production batches
Compared With The Alternatives
| Hard turning | Hard turning is faster on some hardened parts; grinding remains the route where the finest surface finish and tightest size control are required. |
|---|---|
| Manual grinding | Manual grinding depends on the operator's skill; CNC grinding repeats the same result across a batch. |
Use Guide
- Specify grinding only on the features that need it, since it is a finishing cost
- Allow grinding stock on the machined part before heat treatment
- State surface finish in a measurable value rather than as a description
- Send hardness requirements along with the drawing
Questions
Questions Buyers Ask About This Product
When should a part be ground rather than machined?
When the tolerance or surface finish is beyond what turning or milling can hold, or when a hardened part has to be brought back to size.
Can you grind after heat treatment?
Yes, and that is the usual sequence for hardened components, provided grinding stock was left on the part.
Do you handle intricate grinding work?
Yes, CNC control is what makes intricate grinding geometry repeatable.
Do you supply the material?
Either. Material can be supplied by us or free issued by you.
What quantities do you accept?
From single parts to production batches.
