Wuhan Huazhong Numerical Control Co., Ltd (HCNC) is a high-tech enterprise dedicated to CNC

research, development and production. It has a staff of 280. Our technology is supported by the

National Research Center of CNC Technology at Huazhong University of Science & Technology

(HUST), Our annual production capacity is five thousand sets of CNC controllers.

Our leading product Century Star series CNC controller, is well-known for its open architecture and

cost-performance. It has has been widely applied in both industry and education in China. We also

produce servo drives and motors to offer a complete industry solution for our users worldwide. A

National Standard quality test center ensures the quality of our products. We were awarded the

ISO9001:2000 in 2000. Every controller is extensively tested before they are shipped to our users.

We are also actively engaged in global competition. We have conducted two International Workshops

on CNC technology for Developing Countries. Our international market includes Thailand,

Vietnam, Pakistan, Malaysia and Argentina.
