CNC Grinding Machine for Precision Surface Finishing
A CNC surface grinding machine designed for achieving high-precision flat surfaces on metal workpieces. For machinery importers, distributors, and EPC buyers who require tight flatness tolerances and consistent surface finish quality on components such as machine bases, guideways, mold inserts, and precision fixtures.
Typical Applications
- Machine tool components: Base plates, guideways, column slides requiring flatness within 0.005 mm/300 mm
- Mold and die components: Insert surfaces, parting lines, and core plates requiring mirror finish
- Precision fixtures: Workholding plates, datum surfaces, and inspection tooling
- Hydraulic and pneumatic components: Valve plates, cylinder end caps, and manifold blocks
- Automotive components: Brake caliper mounting surfaces, transmission housing mating faces (IATF 16949 context)
Grinding Capabilities
| Parameter | Specification |
|---|---|
| Work table size | Configurable based on workpiece dimensions |
| Max workpiece weight | Depends on table capacity and magnetic chuck |
| Grinding wheel speed | Adjustable, matched to material and wheel specification |
| Surface finish (Ra) | Typically 0.4 to 0.8 micrometer; finer finishes achievable with appropriate wheel and parameters |
| Flatness tolerance | Typically 0.005 mm/300 mm; tighter tolerances subject to drawing review |
| Axis control | CNC-controlled X/Y/Z with programmable feed rates and plunge depth |
| Coolant system | Flood coolant with filtration, directed at grinding zone for thermal control |
Note: Exact specifications depend on the machine configuration and workpiece requirements. Parameters above are typical industry values for this class of equipment; specific capabilities should be confirmed during inquiry based on your drawings.
Why CNC Grinding Matters for Your Project
Flatness and surface finish on mating surfaces directly affect machine tool accuracy, sealing performance, and component longevity. For export machinery orders, EPC contractors and distributors increasingly require documented dimensional inspection of ground surfaces -- not just a surface finish callout, but measured flatness data and roughness readings traceable to the workpiece.
At ChunTian, every grinding project starts with a drawing review and tolerance risk assessment. The grinding process is documented through our pre-production workflow: sample gate approvals, in-process inspection with surface roughness testers and dial indicators, and final dimensional reports included in the QC photo pack.
Company Capability
Zhuhai ChunTian Machine Technology Co., Ltd. has specialized in precision sheet metal fabrication and CNC machining since 2009. Our IATF 16949:2016-certified facility supports projects from drawing to delivery, with a structured pre-production workflow that includes drawing review, tolerance risk assessment, sample gate approvals, FAT records, QC photo packs, and shipment checklists.
