How do you control thin-wall deformation on Coffee Machine tamper & portafilter lug?
The buyer's problem
Thin-wall Coffee Machine tamper & portafilter lug where food-contact stainless & mirror polish warp the moment clamping force or heat beats the stiffness. LusterControl controls it with 5-axis and turn-mill composite (fewer setups, less stack-up), sharp tooling, and carefully tuned coolant and feeds on 60 CNC machines.
What to specify
- Call out wall thickness and flatness explicitly.
- Ask for a first-article with the thinnest feature measured.
- Confirm the shop uses vacuum or soft jaws, not hard clamping.
Low-moq prototyping and a fast path to first articles.
