Thin-Wall Enclosure Frame with Sealing Groove for Equipment Housings
A machined enclosure frame with an open window, a continuous sealing groove around the opening and a stepped mounting flange. The walls are thin relative to the opening, so the finishing passes and the clamping are planned to keep it flat after release.
Material
Aluminum 6061-T6
Tolerance
Flatness 0.05 mm after release
Process
CNC Milling
What This Part Does And What Matters On It
The function of the part, the features that carry the fit, and the requirements that decided how it was machined and checked.
A machined enclosure frame with a large open window, a continuous sealing groove running around the opening and a stepped mounting flange on the outer edge. The walls are thin relative to the size of the opening, which is what makes the part worth describing: the frame will move when the clamping load comes off if it is cut in one heavy pass.
The route used here is to rough the frame oversize, release it, and finish the walls, the flange and the groove with light passes and softer clamping. Flatness is measured on the granite plate after the part is free, and wall thickness is checked at several points around the opening rather than at one.
If you are specifying a similar frame, tell us the flatness you need after the part is unbolted, the groove's function (seal or clearance) and which face is the datum.

Send the drawing with the material, quantity, and the tolerances your inspection actually checks. Owen reviews it against how this part was run and comes back within 24 hours on business days with a price, a lead time, and DFM notes before you commit to anything.
How This Part Was Machined
Roughed oversize, released and finished with light radial passes and reduced clamping force so the thin walls stay flat after the clamps come off. The sealing groove is finished last with the frame free on the table.
How This Part Was Checked
Flatness on the granite plate after release, groove depth around the full perimeter, and wall thickness at several points around the opening.
Flatness of the flange face and groove depth after release
Wall thickness around the opening and step heights
Every Quote Comes With DFM Notes
Owen reads the drawing before pricing it: tolerances that add cost, features that need a second setup, finishes that change lead time. Send a STEP or PDF with the material and quantity, and the quote reflects what is actually machinable, within 24 hours on business days.
