Shaft CNC Machining Parts: 12 Quality Inspection Processes
Learn how VMT's quality control team maintains strict quality standards by conducting dimensional and cosmetic inspections of each order during production. If there is any problem, we will communicate and solve it as soon as possible, or solve it in your way.
DFM Analysis
Before CNC machining, engineers conduct a DFM analysis to identify and resolve potential issues in advance. This ensures optimized designs for efficient manufacturing, minimizes defects, and reduces machining costs.
Dimensional Tolerance Determination
Check whether the parts meet the specified dimensional tolerances, ensure the technical feasibility of the tolerance design, and optimize the production process to meet your quality requirements and cost-effectiveness.
Material Testing
We have long-term stable partnerships with material suppliers for decades and can provide third-party inspection reports from organizations such as SGS, CTI, and TUV.
CNC Machining Production
We have a dedicated team to track order progress, maintaining detailed records for each production run. Photos and videos are transparently shared with customers, keeping you informed about the machining process.
FQC Detection
During the machining production process, dimensional tolerance inspections are conducted every two hours, and the first article is inspected to ensure it meets design and quality standards. This guarantees process stability, product consistency, and improved production efficiency.
SPC / CKP
Implement statistical analysis to monitor and control the manufacturing process and provide inspection reports.
Problem Found
If any deviations, defects, or non-compliance issues are discovered during the machining process, an immediate meeting is held to address the problem.
Problem Solving
Respond within 30 minutes, provide solutions within 2 hours, and resolve within 1 day.
OQC Detection
Before CNC parts leave the factory, 100% dimensional inspection is conducted according to customer drawings. Inspection reports are provided before proceeding to the next processing step.
Surface Finishing
In addition to conventional surface treatments, there are a variety of special surface treatments. We have a full-time SQE to follow up and control each process in the surface treatment factory. After returning to our workshop, the product appearance will be 100% inspected.
Full Inspection
QC specilists will check the parts at every step with testing equipments accordingly,like 3D / 2D project, height/thread /roughness gauge. Offering inspection report with full dimensions for each part.
