Vacuum Chamber Machining

Build-to-print machining of stainless and aluminium vacuum chambers: bodies, doors, viewports and electrode ports, with precision sealing faces and controlled weld distortion.

Finished 304L stainless steel vacuum chamber with flange ports and door frame — 304L stainless steel chamber: body, flange ports and door frame machined to drawing, leak-tested before protective packing.

Layout of top, side, door and bottom ports on a vacuum chamber — Port layout: viewports, feedthroughs, pumping and gauge ports confirmed together with structural strength and cleanability.

Scope

Chamber Bodies & Doors

Fabricated and machined bodies in square, cylindrical or custom shapes, including doors, hinge mounts and locking structures.

Viewports & Electrode Ports

Viewport flange faces, electrode lead-through seats and feedthrough mounting holes, with bore size and position controlled to your interface standard.

Internal Supports & Shields

Target holders, substrate carriers, shields and internal supports, with flatness and assembly clearance controlled.

Process Capability

Machining — 3-axis and 5-axis CNC milling and turning; maximum part size and in-process inspection assessed per job.
Welding — TIG welding of 304/316L stainless and aluminium welding, welded symmetrically to limit thin-wall distortion.
Surface finishing — polishing, passivation, electropolishing and blasting, selected to your cleanliness requirement.
Sealing faces — flange faces and O-ring grooves machined to the roughness and flatness stated on the drawing.

Quality Control

Sealing-face roughness (Ra) and flatness measured and recorded part by part.
Bolt-hole position and viewport / electrode-port concentricity verified before assembly.
Post-weld distortion and chamber opening dimensions re-measured; out-of-tolerance parts reworked and re-inspected.
Deburring, cleaning and rust prevention before dispatch; vacuum packing on request.
Mill certificates and key-dimension inspection records supplied, to support your own leak test and acceptance.

To be clear: we deliver chamber parts and structures, not assembled systems or vacuum integration. Leak testing is performed by the equipment builder or integrator; we can supply matching blanks and fixtures to your test-jig requirements.
