Secure precision pre-machining in Hayward, CA

TCI Aluminum North offers you a seamless way to prepare your aluminum parts for final machining or fabrication. With our Precision Pre-Machining services, you reduce in-house labor and setup time significantly. Imagine the sound of tools being set down as your parts arrive ready-to-assemble, thanks to our edge milling, deburring, and custom profiles.

Precision Pre-Machining


Located in Hayward, CA, TCI Aluminum offers advanced Precision Pre-Machining services that help you eliminate setup time, reduce material handling, and minimize in-house machining operations. Our process delivers ready-to-machine aluminum blanks with superior accuracy, flatness, and squareness-so your parts go from stock to finished product faster.

With precision sawing, edge milling, and squaring to exact customer specs, we provide aluminum blanks that consistently hold tolerances as close as ±0.002" on thickness and squareness within .0005" per inch. That means less fixturing, less surface prep, and more time cutting chips.

Precision Pre-Machining


Our Precision Pre-Machining services are designed to meet your specific needs. We offer capabilities that make your production process smoother. Here's what you can expect:
  • High Accuracy - Cut to tight tolerances for flatness, thickness, and squareness, reducing the need for finish machining.
  • Large-Scale Capabilities - Our CNC-controlled plate saw handles aluminum up to 8" x 144" x 144", enabling precision cuts on even your largest jobs.
  • Automated Efficiency - Programmable control and automatic feed reduce material handling costs by up to 50%.
  • Ready-to-Use Parts - Blanks arrive deburred, pre-squared, and fully prepped for immediate use in CNC or manual machining.

Precision Circle & Ring Blanks - Fast, Accurate, and Cost-Effective

TCI Aluminum / North uses advanced single-turning trepanning technology to machine complex shapes in a single operation. We deliver precision circles and rings with counterbores, tapers, radii, steps, grooves, and countersinks-up to 50% faster than conventional methods. This reduces both lead time and the need for multiple setups.

Lower Costs Through Faster Production


Speed translates to savings. Our efficient cutting process minimizes shop time, lowers labor costs, and helps you get your parts faster-without sacrificing precision or quality.

Precision Capabilities for All Job Sizes


We produce high-accuracy ring and circle blanks in a wide range of sizes and materials:
  • Trepanning: Up to 30" diameter, 2" thick, in aluminum, stainless steel, and other metals.
  • Bandsaw Cutting: For larger blanks, we cut up to 84" diameter, 0.25" to 3" thick from single-piece plate.
  • Whether you need a single prototype or high-volume production, we're equipped to meet your specifications.


Tight Tolerances, High-Quality Finish

  • Dimensional tolerances: ±0.001"
  • Concentricity: ±0.001"
  • Surface finishes: Down to 32 Ra
