The SZGH-540A small CNC milling machine is a compact, high-precision machining center designed to meet the needs of modern intelligent manufacturing. Developed by Shenzhen Guanhong Automation Co., Ltd. (SZGH) — a trusted brand in CNC automation — this model combines reliability, flexibility, and efficiency in a small footprint. Whether you are producing precision metal components, automotive parts, or custom prototypes, the SZGH-540A delivers exceptional performance and long-term stability.
With its mechanical BT30 spindle, high-speed servo system, and precision-grade linear motion components from Taiwan, the SZGH-540A offers the perfect balance between speed, power, and accuracy — making it an ideal choice for small workshops and large-scale production lines alike

Unlike traditional bulky machining centers, this mini CNC milling machine is engineered for compactness without sacrificing capability. The machine dimensions of 1300×1150×2030 mm allow easy integration into limited factory spaces, while its 1900 kg reinforced structure ensures vibration-free performance even during heavy metal cutting.
The workbench (500×400 mm) supports up to 200 kg, providing ample space for small to medium metal parts. This makes it suitable for applications in automotive, aerospace, electronics, and mold manufacturing industries, where precision and repeatability are critical.
At the heart of the SZGH-540A is a BT30 spindle driven by a 1.5 kW motor (optional 2.6 kW or 3.0 kW upgrade). The spindle reaches speeds up to 6000 rpm (optional 9000 rpm or 24000 rpm variable-frequency spindle for high-speed cutting), enabling both fine finishing and efficient metal removal.
