Influence of Custom Fixture Design on Precision in Precision Machining

Fixtures are the foundation of precision machining. Improper clamping causes extrusion deformation and positioning errors, which is a major reason for out-of-tolerance of precision parts, especially thin-walled and complex special-shaped components.

Processing Difficulties: Universal fixtures hardly fit non-standard special-shaped workpieces. Uneven clamping force leads to displacement during machining and failure of geometric tolerances such as position degree.

We design custom fixtures according to product structure of customers, optimize positioning reference, reduce positioning errors caused by clamping and lower extrusion deformation of workpieces, ensuring stable geometric tolerances such as position degree and parallelism for complex parts.

Fixtures are verified by trial production to confirm stable positioning before formal machining.

We customize fixtures for non-standard precision parts in semiconductor, medical and aerospace industries to guarantee machining precision.
