About This Part
Equipment covers look simple until the hole pattern counts. This rear cover is turned and milled from 6061-T6 to a 53.50 mm outside diameter with an R26.25 profile and nine R1.50 scallops around the rim, then drilled and tapped for 2X M2-6H through threads plus a ring of positioned holes from 1.60 up to 5.0 mm that seat the sealing strip and mounting hardware.
Chamfers run C0.2 at the hole mouths, and the tolerance defaults follow GB/T 1804-m for dimensions and GB/T 1184-K for form. The cover gets clear anodize after machining for corrosion resistance with the natural aluminum look kept, which suits front of equipment housings.
Laser marking is part of the route, not an afterthought: the cover carries material code, supplier, production date, and serial number text under RoHS requirements, so every unit in the field traces back to its batch. Final checks cover dimensions with caliper and micrometer, threads with plug gauges, hole positions with pin gauges, and the marking content against the drawing.

Common Questions
Why clear anodize instead of black?
Clear keeps the natural aluminum appearance, which suits covers visible on the equipment exterior. Black is available on the same route if your housing design calls for it.
What does the laser marking contain?
Material code, supplier identity, production date, and serial number, per the RoHS traceability requirement on the drawing. Content is set per your part numbering scheme.
Is the sealing strip seat machined or formed?
Machined. The positioned hole pattern and seating surfaces are cut in the CNC operations, so the strip seats repeatably without hand fitting at assembly.
