Product Overview

As a specialized provider of high-precision CNC machining services, we are dedicated to resolving the complex challenges associated with deformation and tolerance control during the machining of large-diameter, thin-walled components. This precision baseplate is specifically engineered for applications in the semiconductor, optics, and precision automation sectors; it ensures ultra-high flatness while achieving high-precision positional accuracy for complex hole patterns.

Leveraging 15 years of industrial manufacturing expertise, we are capable of processing a wide array of materials—including aerospace-grade aluminum, stainless steel, and specialized alloys—to deliver customized baseplate solutions that meet the world's most rigorous industrial standards.

Core Technical Advantages

Exceptional Flatness and Parallelism Control
Deformation is the primary concern when machining large-diameter, disc-shaped components. We employ unique stress-relief machining processes and vacuum-chucking techniques to ensure that our products maintain micron-level flatness even after machining is complete, thereby meeting the exacting demands of precision assembly.

High-Precision Positioning for Complex Hole Patterns
Utilizing advanced 4-axis and 5-axis CNC machining centers, we complete the machining of all precision holes and slots in a single setup. This fundamentally eliminates the cumulative errors typically associated with secondary setups, ensuring positional tolerances remain within ±0.01 mm.

Semiconductor-Grade Cleanliness and Surface Treatment
We fully understand the stringent requirements placed on components within semiconductor environments. We offer a comprehensive range of surface treatments—including hard anodizing, electropolishing, and Teflon coating—to ensure that components exhibit extremely low outgassing rates and exceptional corrosion resistance.

Fully Digitalized Quality Traceability
Every single baseplate undergoes 100% inspection using a Coordinate Measuring Machine (CMM). Through unique positional markings applied directly to the component's surface, you can easily and precisely cross-reference specific parts with their corresponding production batches and inspection data.
