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.
