Case Study — Stainless Steel Precision Block for a European Machinery Company
A European customer required a stainless-steel block with multiple stepped pockets and a ±0.01 mm tolerance on mating surfaces. Traditional milling methods caused minor deformation and surface variation. Ruicheng’s engineers redesigned the fixturing approach and used optimized 5-axis toolpaths to control heat and cutting force.
The final batch passed 100% CMM inspection and reduced the client’s assembly adjustment time by 35%.
FAQs About CNC Milling for Metal Parts
Can CNC milling achieve tight tolerances for metal parts8?
Yes. With proper fixturing and advanced machines, metal parts can reach ±0.005–0.01 mm depending on geometry.
Ruicheng routinely maintains these tolerances for critical components.
Does Ruicheng support both small and large production runs?
Yes. Our company handles prototype orders, small batches, and mass-production programs.
Production flexibility is one of our major advantages.
What surface finishes are available for CNC-milled metal parts?
Anodizing, polishing, bead blasting, powder coating, brushing, passivation, and plating.
Finish options are selected based on durability, appearance, and corrosion resistance.
Can Ruicheng handle complex or multi-face metal parts?
Yes. Our 5-axis milling capability allows machining of complex components in a single setup.
This ensures higher accuracy and reduces machining time.
