High-Precision Large Diameter Machined Discs with Micron-Level Flatness and Semiconductor-Grade Finishes

As industry-leading experts in precision CNC machining, we specialize in resolving manufacturing challenges associated with large-format, high-tolerance, and thin-walled disc-shaped components. This series of precision indexing baseplates is custom-engineered for semiconductor manufacturing, precision robotics, and high-end automation systems, delivering exceptional structural stability and repeatable positioning accuracy—even within extreme industrial environments.

Leveraging over 15 years of precision machining expertise, we employ unique stress-relief techniques to ensure that our large-diameter baseplates maintain micron-level flatness following complex cutting operations, thereby meeting the most stringent industrial standards.

Utilizing advanced 4-axis and 5-axis CNC machining centers, we complete the machining of all complex hole patterns, cavities, and dowel pin bores in a single setup. This process eliminates cumulative errors at the source, consistently maintaining critical positional tolerances within ±0.01 mm while ensuring flatness meets rigorous assembly requirements.

For large-diameter components made from aluminum alloys and stainless steel, we combine specialized heat treatments with vibration aging processes to effectively eliminate internal stresses. Even under prolonged use or within semiconductor vacuum environments, our components exhibit minimal deformation, ensuring sustained stability and precision.

We offer surface finishing solutions that comply with Cleanroom standards, including:

• Hard Anodizing
• Electroless Nickel Plating
• Electropolishing

These finishes ensure that our baseplates possess high corrosion resistance, low outgassing rates, and superior surface hardness—meeting the exacting demands of the semiconductor and high-end automation industries.

Every baseplate undergoes comprehensive validation through CMM (Coordinate Measuring Machine) inspection, optical projection, and laser surface roughness testing. Each component features a unique serial number engraved on its edge, enabling full traceability of production batches and inspection data to guarantee the precision and reliability of every delivered part.
