Precision Surface Grinding Services
Precision surface grinding serves as the critical final phase in producing complex components that require superior geometric truth. When vertical and horizontal CNC cutting reaches its physical limits, our precision surface grinding in China delivers the high flatness, parallelism, and uniform thickness control required for demanding mating surfaces, hardened plates, and automation assemblies.
Integrated Machining and Grinding Workflow
Managing split orders across separate milling suppliers and secondary grinding shops introduces communication friction, shipping delays, and divided accountability. PRECI5 operates as a consolidated manufacturing partner, unifying multi-axis cutting with precise surface finishing under one roof.
Process Continuity
Our production engineering unifies 5-axis, 4-axis, and turn-mill operations directly with final finishing. Grinding stock allowances are systematically reserved during primary CNC toolpath programming to avoid material deficiency or excessive wheel wear.
Reduced Lead Times
Eliminating off-site transportation between milling facilities and third-party grinding shops removes administrative overhead, prevents shipping transit damage, and shortens the overall production schedule.
Single-Source Accountability
Handling both CNC machined parts grinding and rough machining in-house places complete dimensional ownership on PRECI5. We take full responsibility for print compliance from initial stock setup to final CMM verification.
Our Grinding Equipment and Capacity
Our machine fleet is optimized for repeatable accuracy across low-to-medium batch runs and high-precision tooling plates. We deploy dedicated Japanese surface grinding equipment alongside specialized cylindrical and honing assets.
| Capability | Main Equipment | Origin | Quantity | Travel or Capacity |
|---|---|---|---|---|
| Surface Grinding | Okamoto Surface Grinder | Japan | 2 units | 500 × 200 mm |
Secondary Processing Spectrum: In addition to planar surface grinding, PRECI5 manages external and internal cylindrical grinding, honing, and extrusion honing to accommodate complex part features, shafts, and bore profiles.
When to Utilize Surface Grinding Services
While standard CNC milling delivers efficient material removal, specific mechanical requirements mandate abrasive finishing. Review the primary engineering conditions below where grinding is essential.
Quality Control and Dimensional Verification
Precision grinding requires dedicated measurement systems to validate micrometer-level conformity. Our quality assurance protocol verifies geometric form, surface texture, and post-grinding integrity.
Surface Roughness Testers
Contact profilometers verify specified micro-inch finishes and Ra values across ground planes.
ZEISS CMM
Coordinate measuring machines confirm complex datums, parallelism limits, and positional true position.
Calibrated Micrometers
High-resolution digital micrometers and bench gauges provide multi-point thickness verification.
Coating Thickness Gauges
Ensures post-grinding surface treatments or plating layers remain within exact engineering limits.
