Controlling Surface Roughness in Precision Hardware Processing

Advancing technology and societal development drive increasingly stringent performance and quality demands for precision machining products. Product performance and quality are determined by design and ensured through precision hardware processing, manufacturing, and assembly, encompassing both dimensional accuracy and surface quality. Surface quality stands as a critical indicator, particularly for part reliability under high-speed, high-temperature, and high-pressure conditions.

Machined surfaces transform blank dimensions, shape, and properties via precision machining to meet design specifications. However, turned cylindrical surfaces on precision parts are non-ideal: post-machining, a thin surface layer forms with characteristics distinct from the internal matrix. During precision metal processing, surfaces undergo elastic/plastic deformation under complex stresses (wedging, extrusion, fracture, friction). Combined effects of cutting forces, heat, and environmental media alter the workpiece's original geometric features and physico-mechanical properties.

"Surface quality" thus evaluates compliance of a part's surface layer with technical requirements across:

Geometric characteristics

Physical properties

Chemical properties

Engineering performance

Surface roughness – a key parameter – refers to micro-geometric features of peaks/valleys on machined surfaces, primarily formed by tool motion trajectories during precision machining. Its defining characteristic is a wave height-to-wavelength ratio typically exceeding 1:50.

Importance

Reasonable Temperature Control in Precision Hardware Processing
Precision parts processing adheres to stringent industry standards with varied processes (e.g., cutting in/out). Dimensional and accuracy requirements differ per product, though precision machining typically demands tolerances within 1μm (0.001mm). Significant dimensional deviations yield non-conforming products requiring reprocessing – a time/labor-intensive procedure risking material scrap, cost escalation, and part failure. These factors necessitate rigorous process controls.

Two primary machining forces impact precision:

Extrusion force

Rubbing force

Mitigation strategies include:

Equipment Preparation: Strict pre-machining inspections with immediate fixture adjustments to reduce force transmission

Friction Control: Routine equipment polishing to minimize friction from part-tool contact (e.g., machine tool interfaces), as friction intensifies during extended operation

Temperature Management:
Precision equipment exhibits temperature sensitivity – excessive heat or cold disrupts operational reliability. Implementation requires:

Coolant Application: Use cold-water cooling when operational speeds cause overheating
Example: High-speed grinding generates part-deforming heat during polishing, necessitating immediate cooling intervention
Maintaining optimal process temperatures remains critical for precision control.

Conclusion

5-Axis CNC Machining Process for Stainless Steel Parts
High-precision stainless steel part production using 5-axis CNC technology follows these steps:

Design & CAD Modeling
Part design initiates in CAD software, creating 3D geometry that incorporates required features, tolerances, and material properties. Finalized designs transfer to CAM programming for CNC toolpath generation.

Material Selection & Preparation
Select appropriate stainless steel grades (e.g., 304, 316, 17-4 PH) based on part specifications. Material undergoes cutting into machining-ready rough blanks.

CNC Setup
Load stainless steel blanks into the 5-axis CNC machine. Calibrate equipment, load CAM toolpaths, and secure workpieces for machining operations.

Machining Execution
The 5-axis CNC removes material using rotating cutting tools. Multi-directional workpiece manipulation enables high-precision feature creation with minimal manual intervention.

Inspection & Finishing
Post-machining, parts undergo rigorous QC using precision tools (CMM/laser scanners) to verify dimensional accuracy and surface finish. Additional finishing (polishing/grinding) is applied if required to meet specifications.

FAQ

• Q: Can I get a sample for a check?
• A: Yes, just need sample cost, we will return it back in mass production.

• Q: What tolerances can Crida achieve?
• A: There is no given set of tolerances that fits all processes and materials. In every case, the final tolerances on your part will depend on a number of factors, including but not limited to: Part size Design Geometry The number, type, and size of features Material(s) Surface finish Manufacturing Process Once your order is confirmed, we will review your design and provide a design for manufacturing review, pointing out any areas where we may not be able to achieve your desired tolerances. It’s helpful if you can specify which areas in your design have critical tolerances that must be met and which can be slightly modified if needed to reduce the time and costs involved.

• Q: What parts can you buy from Crida?
• A: CNC machining milling parts / turning parts, stamping parts, sheet metal fabrication parts, bending parts.

• Q: Is your organization committed to the concept of total quality management?
• A: Yes, no matter bending, laser cutting or CNC processing, workers will conduct the first sample inspection and random inspection during processing to ensure product quality.

• Q: After-sales service team
• A: If you have any problems after receiving the product, you can provide feedback through voice call, video conference, email, etc. within one month. Our team will provide you with solutions within a week.
