At JYH CNC Precision Machining, we specialize in producing high-accuracy motor housing components designed for demanding industrial, automation, and robotics applications. Each part is engineered with uncompromising attention to detail — from raw material selection to precision CNC machining, advanced hard anodizing, and full QC inspection.
Our motor housings are designed to deliver maximum structural rigidity, corrosion resistance, thermal stability, and extended operational life—making them ideal for motors that operate in high-load or high-temperature environments.
Product Overview
These custom-engineered aluminum motor housings are manufactured using multi-axis CNC machining, ensuring tight tolerances, excellent concentricity, and repeatable quality across every batch. The matte dark-grey finish results from a 50 µm Hard Anodized coating (MIL-A-8625 Type III), providing superior surface hardness, wear resistance, and enhanced protection against corrosion.
