Question 1

When to pick 5-axis vs 3-axis for Industrial Automation valve body & coupling, and how fewer setups cut error and cost for buyers.

Accepted Answer

Buyer's short answerFor most Industrial Automation valve body & coupling with seal seat flatness & pressure hold, a 3-axis center is enough and cheaper. Choose 5-axis only when the part has multi-side features, deep cavities or tight concentricity that would need several setups. More setups = more stack-up error and higher cost.Why it matters to youFewer setups → better concentricity and shorter lead time.LusterControl runs 60 CNC machines including 5-axis and turn-mill composite in-house.We recommend the lowest-cost process that still meets your print — we do not up-sell axes you don't need.White-label oem and reliable re-export lead times.
