Quality Control & Dimensional Inspection Standards
Every precision gear leaving our production floor undergoes rigorous dimensional verification against the approved technical drawing. We enforce strict in-process logging and final metrology controls to ensure complete geometric accuracy, tooth profile integrity, and total reliability in heavy-duty applications.
Our Inspection Protocol
A controlled verification process from technical drawing review through final reporting and shipment release.
Technical Data Verification
Before the first cut is made on our machines, our engineering team thoroughly reviews your 2D drawings and 3D CAD data to verify tolerance feasibility, module specifications, and material heat-treatment limits.
In-Process Machining Inspections
Dimensional checks are performed systematically during the blank turning, milling, and gear-cutting stages. This ensures that every gear remains within the specified geometric boundaries throughout the manufacturing cycle.
Final Metrology & Verification
Post-production and after heat treatment, every batch is subjected to final inspection. We verify tooth thickness, pitch alignment, runout tolerances, and surface roughness parameters against your engineering requirements.
Inspection Documentation
We provide detailed dimensional inspection reports and material test certificates with your shipment upon request. Your internal quality management team receives fully traceable documentation.
Our Inspection Instruments
To maintain strict geometric tolerances, our quality assurance team utilizes calibrated precision measuring instruments.
Precision Micrometers & Calipers
High-accuracy digital calipers, external and internal micrometers, and vernier gear tooth calipers for direct dimensional tracking.
Bore & Thread Gauges
Specialized plug, ring and bore gauges to ensure exact shaft fitments and internal spline accuracy.
Surface Roughness Testers
Digital profilometers used to verify required surface-finish Ra values after machining or grinding.
Hardness Testing
Verification of surface and core hardness values, including Rockwell HRC and Brinell HB, following heat-treatment processes.
