Specializing in custom metal cutting and precision machining services.
At Shenzhen Hongsinn Precision Co., Ltd. we specialize in manufacturing custom components, performing precision metal cutting jobs, and delivering custom precision metal machining services. Our advanced facility combines cutting-edge technology with engineering expertise to serve aerospace, medical, automotive, and industrial sectors.

CNC (Computer Numerical Control) machine tools are highly efficient automated equipment consisting of mechanical components and numerical control systems for machining workpieces of complex shapes. It is equipped with a tool library with automatic tool change function, so the workpiece can complete multiple machining operations after one setup.
The CNC system can automatically control the machine tool to perform different metal processing procedures, including automatic tool replacement, spindle speed selection and feed speed adjustment. Therefore, the workpiece can be completed continuously through drilling, boring, milling, reaming and tapping processes, greatly improving the processing efficiency and accuracy.
CNC metal machining significantly reduces auxiliary setup time such as workpiece clamping, measurement and machine tool adjustment, and is particularly suitable for processing parts with complex shapes, high precision requirements and strict repeatability requirements. This efficiency makes the production process faster and more precise.
