Vacuum flanges and interface components
CF, KF and ISO-K flanges and interface parts machined to drawing, with manufacturing and inspection focused on knife edges, O-ring grooves, face flatness and mating fits.
Requirements we can discuss
- CF knife-edge flanges, KF and ISO-K flanges, blanks, centring rings and adaptors made to drawing
- Review of knife edges, O-ring grooves and sealing faces against the mating flange
- Delivery as single parts, pairs or assemblies, with the same leak-test readiness as the chamber
Review first, then agree the process
Drawing review defines the material, turning sequence and mating relationship. Knife edges and sealing faces are turned in one setup, grooves are machined to drawing, and where the drawing is silent the mating standard part is measured and cross-checked. Welded parts receive sealing-face finishing and re-check after welding; leak testing follows the agreed scope.

What to include in your enquiry
- Flange size or drawing, plus mating part details
- Material grade, sealing-face and surface requirements
- Quantity, delivery form (single, pair or assembly) and leak-test requirements
If you do not yet have a formal drawing, start with a non-confidential outline. Drawings and sensitive materials can be exchanged separately.
