Precision CNC Milling Custom Aluminum Housing, Cavity Shell for Special Automation Equipment OEM

Product Introduction

This precision CNC milled cavity housing is fully machined from solid billet aluminum block. We select high-grade aluminum alloy as primary raw material to guarantee excellent strength, lightweight property and dimensional stability. Adopting 5-axis CNC milling process, the complex multi-cavity structure, step holes and mounting features are formed in one setup. Strict tolerance control and hard anodizing surface treatment greatly improve wear resistance and corrosion resistance. We support custom manufacturing with a wide range of metal materials for different industrial automation requirements.

Core Advantages & Features

1. High-performance solid billet aluminum material We machine from whole solid aluminum block instead of casting. No casting pores or sand holes. The internal metal grain remains continuous, so the housing has much higher structural strength and reliability, suitable for high vibration & heavy-load automation equipment.

✍ Key note: Cast housing has hidden defects; billet CNC machined parts can withstand long-term cyclic load.

1. Complex multi-cavity 5-axis CNC machining capability Multi cavities, stepped holes and irregular outer profiles are finished in single clamping. Ensures concentricity and position accuracy of multiple hole groups.

✍ Key note: Eliminates repeated re-clamping error for complex multi-chamber structure.

1. Diversified material selection for custom demand Besides 6061 &7075 aluminum, we can process stainless steel, brass, copper, POM, peek and other engineering plastics. You can choose materials based on weight, anti-corrosion, conductivity or cost requirements.

✍ Key note: One-stop machining service for metal & high-performance plastic materials.

1. Controllable surface treatment & strict quality inspection Hard anodizing, sandblasting, passivation, powder coating are optional. Each workpiece is inspected by CMM and caliper before delivery.

✍ Key note: Full dimensional inspection report can be provided on request.

Application Scenarios

• Special automation equipment transmission cavity
• Automated fixture & positioning base
• Precision fluid control valve housing
• Robot joint & actuator housing
• Custom high-precision test equipment housing

✍ Key note: Suitable for equipment requiring high precision, lightweight and long service life.
