VISIT US TO DISCUSS YOUR NEXT PROJECT. LET'S BUILD PRECISION TOGETHER.
Carbon steel CNC machining is a robust precision fabrication method tailored for carbon steel’s outstanding hardness, tensile strength and low cost. Optimized cutting parameters and rigid cutting tools enable one-setup production of intricate parts ranging from thick-wall mechanical brackets to transmission shafts with varied threaded and block geometries. By controlling cutting vibration and minimizing repeated clamping, this process delivers tight dimensional accuracy and premium surface finish for machinery, automotive, hydraulic and engineering manufacturing sectors.
Custom stainless steel CNC machining is our specialized metal processing service, producing rust-proof, corrosion-resistant stainless steel precision components for medical, food, marine and electronic global clients. Equipped with full set of 3/4/5-axis multi-axis CNC equipment, we process 303, 304, 316 stainless steel for rapid prototypes, small custom runs and mass production. Certified ISO 9001:2015, our stainless steel parts feature tight tolerances, smooth surface and stable anti-corrosion performance.
Our automated CNC production converts your CAD, STEP, IGS, STL drawings into finished stainless steel components efficiently. We solve the processing difficulty of stainless steel work hardening and thin-wall deformation. We deliver one-stop stainless steel machining solutions including material matching, DFM optimization, precision cutting, custom surface finishing and strict quality inspection for all custom stainless steel parts.
