Tight tolerance machining refers to producing features that hold dimensional limits well beyond standard shop practices—often critical for mold fits, assembly interfaces, and functional mating surfaces. Achieving these tolerances requires stable machines, controlled environments, and disciplined measurement routines.
Tolerance targets should be tied to function, not specified tighter than necessary. Over-specification increases cost without improving product performance. Process capability reviews, tool path strategy, and post-machining grinding or EDM can all influence final results.
RIXIN supports tight tolerance machining for mold components and industrial parts with CNC milling, wire EDM, EDM, and precision grinding. Documented inspection and quality systems help export customers validate critical dimensions before parts move to assembly or molding.
