Figure 8 Servo Transition Flange Plate in 6061/7075 Aluminum, CNC Machined
Figure 8 transition flange plate in 6061-T6 or 7075-T6 aluminum: center distance held to plus or minus 0.02 mm, bearing bore coaxiality 0.015 mm, silver anodized. CMM checked 100 percent. Quote in 24 hours.
General Industrial Components
One piece flange plate that joins a rotary bearing or servo motor mount to a rectangular sensor or display module. The two centers are machined in one setup so the 0.02 mm center distance survives assembly.

About This Part
This plate carries two different mounting worlds on one body: a circular end that accepts a servo motor flange or bearing seat, and a rectangular framed end that hosts a vision sensor, display, or cable module. The two centers are positioned at a controlled distance of plus or minus 0.02 mm, and both are cut in a single clamping on a four axis machining center, so second op error never enters the equation.
The circular end carries a precision turned through bore for the motor or bearing fit, surrounded by a ring of counterbores, helicoil ready threaded holes, and mounting holes arranged on the bolt circle. The rectangular end is milled with a square through window for cable or optical access, with four symmetric counterbored fixing holes around it. M2.5, M3, and M4 threads across both faces hold position within 0.03 mm.
Machining runs from plate blank through both face milling, bore and window work, high speed drilling and tapping, then micro deburring before bead blast and silver anodize. The bearing bore coaxiality is held at 0.015 mm and face parallelism at 0.02 mm. Every plate is measured on the CMM for center distance and hole position before shipment, because these two numbers are what the assembler actually feels.

Common Questions
Why machine both cores in one setup?
The 0.02 mm center distance is a stack of two positions. A second op flip introduces fixture error that eats most of that band, so the controlled features are cut before the part leaves the first clamp.
Will the anodize change my hole sizes?
Anodize builds a few microns per surface. Threads and the bearing bore are either masked, or final tapped and reamed after anodize, so mating hardware still fits.
