🇺🇸 U.S. Automation Systems Integrator | High-Precision CNC Machined Aluminum Baseplates for Robotic Transport Modules

Project Background

In early 2025, we were approached by a U.S.-based automation systems integrator that specializes in high-speed transport systems used in semiconductor packaging and electronics final assembly, particularly focusing on cnc machined aluminum baseplates.

Benefits of Using CNC Machined Aluminum Baseplates in Automation

The client was preparing to launch a new generation of linear shuttle-based conveyors with modular installation frames. The cnc machined aluminum baseplates required for this system had to meet tight flatness and parallelism specs, while also accommodating various threaded inserts and alignment dowels. Their existing supplier struggled with consistency across batches, resulting in assembly gaps, vibration issues, and field rework.

After reviewing our CNC aluminum capabilities via our website and LinkedIn portfolio, the client initiated a technical review and submitted a trial PO for 8 cnc machined aluminum baseplates.

Client Requirements

Material: 6061-T6 aluminum, with material certs per ASTM B221
– Part Size: 420 mm × 285 mm × 16 mm

 

  – Flatness ≤ 0.05 mm across surface
  – Threaded inserts (helicoils) for M4, M6 fasteners
  – Press-fit dowel holes with location accuracy ±0.01 mm
  – Symmetrical chamfers on all edges
– Surface Finish: Clear anodized (Type II) with masked grounding pads
– Quantity: 8 pcs prototype → 150–200 pcs monthly forecast
– Lead Time: ≤ 10 working days (including anodizing)
– Documentation: CMM inspection, insert torque tests, anodizing cert, packaging photos

Key Technical Challenges

  1.  Maintaining Flatness Over Large Surface
  2. Post-Machining Insert Installation
  3.  Masked Anodizing with Electrical Ground Points
  4.  Consistency Across Batches

Challenges & Solutions

Precision Fixturing & Machining

 Custom vacuum fixture designed for 420 × 285 × 16 mm plate.
– Toolpaths generated in PowerMill with adaptive roughing and high-feed finishing strategies.
– Machining done in temperature-stabilized room (23°C ±0.5°C).

Installed all inserts using depth-limited pneumatic drivers.
– 100% verified with torque test and surface flushness gauge.
– Failed or angled inserts were scrapped before proceeding to anodizing.

 Created 3D printed masks based on DXF layout for copper pad regions.
– Anodizing done with clear finish Type II, Class 1 (no dye), followed by resistivity check.

Created inspection template and CMM report standard for every batch.
– Part serialization added with laser marking on back side.
– Provided packaging photos, anodizing cert, and material lot trace for each delivery.

“Every plate fit right into the frame without adjustment. The ground pads tested perfect, and the inserts were spot-on.”

Future Collaboration

The prototype run of 8 plates was delivered in 9 working days. The client passed their internal assembly test and approved the fixture configuration for ongoing production. As of April 2025, we are delivering 150+ plates per month in full kits.

The client has also invited us to support new vertical panel brackets and cable tray bases in their upcoming line expansion.

The client especially recognized our strengths in

– Consistent flatness and hole-to-hole accuracy
– Proper insert installation and quality control
– Fully documented anodizing and torque data
– Fast response and clean packaging

Project Summary

This project highlights our strength in:
– Precision CNC machining of medium-to-large aluminum parts
– Insert installation and specialty anodizing coordination
– Reliable short-turnaround delivery with documentation

We don’t just machine to spec—we build long-term process consistency.
