Question 7

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.Spare-part reproducibility and rework assurance.

Question 10

Ra 0.2 µm mirror finishing on Semiconductor manifold & wafer clamp: why smoothness matters and the proof a buyer should request.

Accepted Answer

In plain buyer termsRa is roughness. Lower Ra = smoother, cleaner, less friction and easier to sterilize or seal. LusterControl reaches Ra 0.6 μm (standard), up to 8K mirror Ra 0.2 μm on stainless. For Semiconductor manifold & wafer clamp where ultra-clean passivation & particulates, that smoothness is often the difference between a seal that holds and one that weeps.What to ask your supplierRequest the Ra value on the print, not just "polished".Ask for a surface-profile trace, not a photo.Confirm electropolishing is done in-house so lead time stays short.Lock moq, unit price curve and on-time delivery.
