Precision Quality Control System
for CNC Machined Parts
From drawing review and material verification to in -process inspection, CMM measurement and final shipment checks, Tik Precision helps reduce quality risks before precision parts reach your production line.
- Quality Control Process
Quality assurance at Tik Precision
Our standard machining tolerance is 0.05 mm. Depending on geometry and material, precision-grade components can be held to 0.002 mm. Every part goes through CMM inspection, optical measurement and surface analysis before it ships.
Tolerance range
Achievable tolerance depends on part geometry and material.

Quality Control -End-to-End Inspection & Verification
- CRITICAL FEATURES INSPECTION
Focus: Fit, Function & Cosmetic Critical Features
Precision component failures usually stem from non-conformance on critical features, not bulk geometry. We verify tolerance zones, hole location accuracy, functional mating surfaces and cosmetic regions that directly impact assembly performance, end-use function and customer quality acceptance criteria.
Tight Tolerances
Critical dimensions, hole positions, flatness, perpendicularity and profile requirements can be reviewed according to drawings and inspection notes.
Hole Location & Hole Feature Inspection
We inspect hole positions, hole spacing, bore size, counterbores, countersinks and hole perpendicularity to ensure accurate pin fit, fastener assembly and fixture alignment.
Surface Finish
Machined surfaces, sealing faces, contact surfaces and roughness requirements can be checked when Ra or finish requirements are specified.
Cosmetic Surfaces
Visible surfaces for anodizing, plating, polishing and coating are visually inspected to eliminate scratches, dents, stains and coating non-conformities.
- Inspection Equipment
Precision Metrology - for Dimensional, Geometric & Surface Validation
Inspection equipment is selected based on part geometry, tolerance class, drawing specifications and customer-specific requirements. We perform dimensional measurement, GD&T verification, surface roughness evaluation and thread inspection to validate part conformity before shipment.
