What Precision Grinding Controls
A dressed abrasive wheel removes small, controlled amounts of stock to finish critical surfaces after machining or heat treatment.
- Improve flatness, roundness, parallelism and dimensional fit.
- Produce controlled roughness on functional and bearing surfaces.
- Finish hardened or wear-resistant parts with minimal cutting force.
Grinding Processes
Select the Process for the Surface
The correct method depends on workpiece geometry, datums, tolerance, finish target and production quantity.
표면 연삭
Flat faces, thickness, parallelism and controlled surface finish.
원통 연삭
External diameters on shafts, rollers, journals and precision spindles.
내부 연삭
Bores, bearing races, sleeves and internal cylindrical features.
센터리스 연삭
Repeat external diameters on pins, rods and tubes without center holes.
Creep-Feed Grinding
Deep profiles and difficult alloys using slow feed and controlled cooling.
수동 연삭
Deburring, weld blending, repair and localized low-volume finishing.

연삭 관련 자주 묻는 질문
Plan Your Precision Grinding Project
What determines precision grinding cost and lead time?
Material hardness, stock allowance, tolerance, surface finish, quantity and inspection requirements are the main factors.
How is batch-to-batch repeatability maintained?
We control the wheel, dressing cycle, machining parameters, coolant, workholding and inspection method.
What causes chatter marks during grinding?
Common causes include wheel imbalance, poor dressing, unstable clamping, spindle wear and unsuitable parameters.
How is grinding surface integrity verified?
Dimensions, geometry, roughness and visible burn are checked. Additional testing can be provided when specified.
What quality documents are available?
CMM reports, dimensional results, roughness records and material or heat-treatment certificates are available on request.
