ALMA's main business is the design and production of tailor-made components and systems for complex drive requirements that also include ultra-high vacuum engineering.
The product range covers high-precision vacuum components like rotary feedthroughs and direct drives e.g. for thin-film technology up to semiconductor, LED/OLED- and solar module production.
products: Vacuum screws
ALMA driving elements finishes ordinary screws by subjecting their surfaces to high-grade precision machining and modifying their “aerodynamics”.
With the perfection of their properties, they become very special ALMA vacuum screws.
The four main production steps in the finishing of a vacuum screw
1. High-precision drilling
2. Milled countersink
3. Superfine Post-Rolling of threads
4. Silver- and gold-plating
