Grinding

Our precision internal and external cylindrical grinding and centerless grinding services deliver exceptional roundness and cylindricity for shafts, sleeves, and rotary components. Utilizing high-precision grinding spindles and closed-loop feedback control technology, we achieve machining capabilities with diameter tolerances of ±0.002 mm and roundness within 0.001 mm, along with excellent surface finish. This process effectively eliminates heat treatment distortion, significantly improving bearing fit accuracy and fatigue life, making it ideal for critical applications such as aerospace drive shafts, medical devices, and precision motor rotors.

Micron-Level Roundness and Cylindricity

Roundness as tight as 0.0005 inches and cylindricity controlled within 0.001 inches significantly improve bearing fit accuracy.

Machining of High-Aspect-Ratio Shafts

Utilizing centerless through-grinding technology, the machine effortlessly processes slender shafts with aspect ratios exceeding 10:1, preventing bending and deformation.

Quick Changeovers and Batch Efficiency

Automatic grinding wheel dressing and an in-line measurement system reduce setup time, enabling efficient production for medium to large batches.

Usage Advantages

Our precision grinding process offers significant advantages for industrial applications with stringent requirements for surface finish, flatness, and dimensional stability.

Enhanced Precision Capabilities

Precision grinding utilizes high-rigidity grinding machines and online compensation systems to achieve sub-micron control over flatness, roundness, and cylindricity, ensuring consistency between surface quality and geometric accuracy.

Adaptability to Complex Structures

Grinding technology can process complex structures such as thin plates, slender shafts, internal and external conical surfaces, and stepped shafts, providing precision solutions—unattainable with traditional processes—for hydraulic valve spools, precision bearings, and medical implants.

Optimized Production Efficiency

Through automatic dressing compensation and centerless through-grinding technology, we significantly reduce the processing cycle per part while minimizing setup changes and manual intervention, providing customers with efficient and stable delivery capabilities.

Precision Grinding Support for Surface and Dimensional Refinement

TaiMachining's grinding support is useful when machined components require additional surface refinement, fit-related finishing, or dimensional control beyond the primary milling or turning operation.

Where grinding fits

Grinding is often discussed for flat, round, mating, sliding, or sealing surfaces where surface condition and dimensional refinement matter. It may be used after milling or turning when the drawing calls for a more controlled final surface.

Typical ground components

Typical grinding RFQs may include plates, spacers, shafts, sleeves, tooling-related parts, and components with surfaces that need careful contact, alignment, or fit in an assembly.

Material and finish discussion

Grinding requirements should be tied to the drawing rather than assumed. Surface finish expectations, heat treatment state, material, and functional surfaces should be identified before confirming the manufacturing route.

Quality and inspection considerations

For grinding work, inspection planning usually focuses on critical surfaces, thickness, diameter, flatness-related requirements, and how the ground features interact with mating components.

RFQ guidance

For a grinding quote discussion, send the drawing, material, quantity, finish notes, and clear identification of the surfaces or dimensions that require grinding.

Prepare a drawing-based RFQ discussion

Share drawings, material, quantity, finish expectations, and inspection notes so the team can review the manufacturing route and discuss the next step.
