This precision CNC-machined assembly comprises two purpose-built components—the Front-End Extension Frame (Part-001) and Main Chamber Housing (Part-002)—engineered as a seamless, modular core structure for high-end industrial equipment.

The Front-End Extension Frame features an open, weight-optimized skeleton design (with 4 long-strip weight-reduction windows) paired with a precision-machined circular datum interface. This balances exceptional structural rigidity with lightweight performance, while providing a coaxial connection point to align upstream system components.

Complementing it, the Main Chamber Housing is a closed-cavity structure with 4 precisely arrayed internal chambers—serving as the primary mounting base for critical equipment components. Its tight-tolerance assembly face (Ra 1.6μm flatness) ensures perfect alignment with the Front-End Frame, forming a unified skeleton post-assembly.

Crafted from 6061-T6 aluminum alloy via multi-axis CNC milling (with >75% material removal rates), both parts undergo natural anodization/sandblasting for durability. When assembled (via torque-controlled M5 bolts), the unit achieves ≤0.03mm overall coaxiality, supporting rated static loads of ≥50kg along the axis direction. It is ideally suited for precision motion modules, high-end testing instruments, and custom automated systems.

Its modular design also accommodates tailored adjustments (dimensions, hole patterns, surface finishes) to match unique equipment specifications, making it a reliable, cost-efficient solution for integrating load-bearing, component mounting, and alignment functions in high-performance industrial setups.
