Quality Assurance

One of the essential workhorses for product verification is our Coordinate Measuring Machine(CMM). We use it every day to qualify rapid prototypes and machined parts that have complex geometries with tight tolerances.

At Present, we have two ZEISS CMMs-MMZ G large bridge CMM and ACCURA II bridge CMM, and one laser tracker Leica AT901.

Our quality assurance program is focused on providing confidence that quality requirements will be fulfilled, both by our internal staff and through our clients’ expectations.
