Custom 5 Axis CNC Machined Aluminum Bearing Block Machine Positioning Connection Flange

Product Overview

This 5-axis CNC milled aluminum alloy machine bearing seat is a high-precision customized mechanical positioning connection flange, specially developed for automation equipment, precision machine tools, and industrial mechanical transmission systems. Different from ordinary stamping and casting parts, this product adopts integral CNC five-axis one-time forming technology, with no welding and no secondary splicing, which perfectly ensures the overall structural stability and positioning accuracy of the part.

Core Material Advantage Highlight: We adopt high-grade 6061-T6 aviation aluminum alloy as the base material, which is the most widely used high-precision aluminum material in the mechanical industry. It integrates light weight, high rigidity, corrosion resistance, and excellent machinability, completely solving the problems of heavy weight, easy rust, and poor precision of traditional iron and steel bearing seats. It is the preferred material for high-end automation precision connecting parts.

Product Basic Parameter Specification (Estimated Standard Size)

All dimensions are standard customized conventional sizes, and full-size non-standard customization is supported according to customer drawings and samples.

Core Processing Technology Characteristics

As a professional CNC custom manufacturer, we adopt five-axis linkage precision milling process for this bearing seat, which is far superior to ordinary three-axis processing in structural precision and three-dimensional fitting degree:

1. Integral One-piece Forming: The whole part is milled from a whole aluminum bar, no assembly gap, effectively avoiding positioning deviation and structural looseness caused by splicing processing.
2. 360° Full-dimensional Precision Machining: Five-axis equipment realizes one-time clamping and full-structure processing of holes, grooves, cavities and chamfers, with repeated positioning accuracy up to ±0.01mm, meeting high-precision equipment assembly standards.
3. Fine Deburring & Smooth Cutting Texture: All hole walls and groove surfaces are finely polished, no burrs, no tool marks, ensuring smooth bearing rotation and precise equipment docking.
4. Structural Optimization Milling: On the premise of ensuring structural rigidity, the hollow cavity and arc groove structure are optimally milled to reduce the self-weight of the part, reduce equipment operation load, and improve mechanical operation efficiency.

Key Product Advantages (Core Selling Points)

Highlight 1: High Rigidity & Anti-deformation 6061-T6 tempered aluminum material has stable molecular structure, high overall hardness, and strong pressure resistance. It will not deform or displace during long-term high-frequency operation of the equipment, ensuring long-term accurate positioning of the connecting flange.

Highlight 2: Lightweight & High Efficiency Compared with traditional steel bearing seats, aluminum alloy material reduces 35% of self-weight, effectively reduces the overall load of automation equipment, reduces equipment energy consumption, and improves operation stability.

Highlight 3: Excellent Corrosion & Oxidation Resistance The aluminum alloy itself has natural oxidation resistance. Optional anodizing treatment further enhances surface wear resistance and corrosion resistance, adapting to various complex working environments such as workshop humidity and oil pollution.

Highlight 4: High-precision Positioning & Strong Versatility Strict tolerance control of mounting holes and bearing holes, precise docking with mechanical bearings and equipment flanges, suitable for positioning connection of various precision machine tools and automation equipment.
