Chassis (AISI 5140)

Material: Alloy Steel
Surface Treatment: Polished / Phosphate Coating / Oxidation
Tolerance: 0.005mm
Technology: CNC Machining
Certification: ISO9001 & ISO14001

Crafted from AISI 5140 alloy steel, this precision-machined chassis serves as a rugged structural backbone for heavy-duty industrial automation, test equipment, and high-load machinery.

With years of specialized experience in producing high-performance steel chassis and structural components, we focus on machining AISI 5140 and other alloy steels to meet the rigorous demands of industrial environments.

Our multi-axis CNC machining ensures exact tolerances and superior flatness. The precision-finished surface can be enhanced with optional treatments like black oxide or phosphate coating to boost corrosion resistance.

Every critical dimension, from mounting holes to guide rail channels, is verified with our CMM inspection process, ensuring strict adherence to your 0.005mm tolerance requirements and delivering reliable alignment and consistent performance over extended use.
