Three FA Builds

Engineering evidence, not stock imagery.

Each case study begins with the supplied engineering drawings, then shows the selected components and the 3D assembly. Click any 3D card below to load the STEP file in-browser.

01 / Automation

Multi-Station Indexing Mechanism

Five-station equal-pitch mechanism

Download STEP

A five-station indexing mechanism is designed around a synchronized pitch-transfer motion and a compact linear-guiding package. The supplied drawing set shows how the base plate, linkage, guide rail, pins, and locating hardware work together as a repeatable indexing assembly. The selected BOM combines PMI linear motion and standard locating components so the mechanism can be assembled, serviced, and scaled with a consistent component record.

02 / Material Handling

Material Tray Cyclic Lift

Download STEP

This cyclic material-tray lift combines an aluminum profile frame, belt conveyor, lifting module, guide shafts, and a compact pneumatic circuit. The supplied views document the full material path from the conveyor section to the raised work position and back again. Its BOM reflects the practical mix of standard motion, conveyor, profile, and locating parts needed to make a compact handling cell easy to procure and maintain.

03 / Assembly Automation

3-Axis Automatic Screw Fastening Machine

Download STEP

This three-axis screw-fastening cell coordinates a horizontal transfer axis, a vertical lifting axis, and a screw-driving head around a dual-workpiece fixture. The supplied drawing set shows the chuck, electric screwdriver, guide shafts, linear bearings, cylinders, sensors, and drag-chain supports arranged into a compact assembly. The 64-line BOM makes the integration boundary clear and gives procurement teams a practical starting point for component sourcing.
