Quality Control Standards

Measuring Facilities

At Grafar Technology, we are committed to delivering Zero-error work-holding solutions with uncompromising precision. Our in-house metrology lab is equipped with state-of-the-art measuring facilities, including CMM (Coordinate Measuring Machine), Contour Tester, Profile Projector, and Surface Tester. Every part assembled in our work-holding solutions undergoes rigorous inspection to ensure Flawless accuracy and reliability. With our advanced quality control processes, we guarantee perfection in every product we manufacture.

Co-ordinate Measuring Machine [Make TESA]

To maintain the precision our CNC lathe chucks and VMC, HMC, and VTL fixtures are known for, we use a high-accuracy CMM to inspect critical dimensions at every stage of manufacturing.

• Ensures perfect fit and alignment for high-performance work holding.

• Checks each part before assembly to eliminate dimensional errors.

• Verifies every component against CAD models and design tolerances.

• Reduces rework and downtime, improving efficiency and consistency.

• Backs our quality promise with reliable, data-driven inspection.

At Grafar Technology, every CNC chuck and fixture we manufacture is tested for surface finish to ensure proper function, durability, and accuracy in demanding machining environments.

• Ensures secure, vibration-free clamping with precision-finished contact surfaces

• Reduces friction and wear, increasing product lifespan and performance

• Prevents misalignment by maintaining surface flatness and consistency

• Supports high-quality coatings and treatments with controlled roughness

Profile Projector [Make Mitutoyo]

At Grafar Technology, we use high-precision profile projectors to verify the critical geometries of every chuck and fixture we manufacture — ensuring reliable, accurate performance on the shop floor.

• Inspects key profiles, angles, and radii to guarantee perfect fit and function

• Detects micro-level deviations invisible to standard inspection methods

• Uses non-contact measurement to preserve part integrity

• Confirms design accuracy against CAD drawings and tolerance specs

• Eliminates profile-related errors that can lead to misalignment or vibration

At Grafar Technology, we use precision contour testers to verify the critical profiles of every chuck and fixture we produce — ensuring flawless performance in CNC, VMC, HMC, and VTL applications.

• Checks complex profiles and contours to prevent misalignment and slippage

• Ensures uniform clamping surfaces for stable, vibration-free machining

• Detects micron-level deviations in curved and angular features

• Supports precise fit and interchangeability of multi-component assemblies

• Reduces rework and scrap by catching errors early in the process
