About This Part
This long thin plate is a panel workhorse: 133.70 plus or minus 0.05 mm width pairs, 19.25, 25.00, and 30.75 plus or minus 0.05 mm feature bands, end radii at R6.75 and R4.75 plus or minus 0.05, and 3.00 mm plate thickness. The drawing carries a 50 plus or minus 0.1 dimension across a 144.2 mm span direction.
The hole field mixes three fits: M3 tapped through holes, M3 x 4 press holes for pins, and M2.5 countersunk holes for flush hardware. A central square boss with a square window adds stiffness and a locating feature without giving up the thin section.
Process is CNC milling of outline and datum edges, radius and slot work, drilling and tapping of the hole field, deburring, then anodize per drawing. Inspection runs caliper and micrometer, CMM on hole positions, thread gauges, and appearance.

Common Questions
Why mix tapped, press, and countersunk holes on one plate?
Each fit has a job: threads for removable hardware, press holes for located pins, countersinks for flush heads. One plate, three kinds of fastening, all held to position.
How does the plate stay flat at 3 mm?
Stress relieving passes and symmetric machining, plus the boss which doubles as a stiffener across the span.
