The traditional multi-spindle drilling machine, commonly known as multi-spindle, multi-hole drilling or multi-spindle drilling, is a machine tool equipment used for drilling and tapping in the mechanical field. It has a history of more than 30 years. Because it is not long in China, the traditional multi-axis device has certain limitations and defects in rigidity and accuracy, which many enterprises have never heard of. At the end of 1990s, in order to solve the limitation of multi-spindle, multi-spindle machine tool with rectangular guide rail and multi-spindle combined drilling machine were introduced from Japan. Good rigidity, suitable for all kinds of aperture processing, widely used in automobile industry, motorcycle industry, valve industry, pump industry and other batch processing industries. At present, the domestic multi-spindle drilling machine has been developed to process 1 to 50 holes at the same time, and the maximum aperture can process 4 φ50 holes at the same time. On the basis of multi-spindle drilling machine, multi-spindle combined machine tool and multi-spindle drilling and tapping combined machine tool are extended, which can process multi-station or multi-surface at the same time. There are power head simple combined machine tools, turntable combined machine tools, slide rail combined machine tools, etc.
Zhejiang Handa Machinery Co., Ltd. invested a lot of R&D energy in developing multi-spindle drilling machines and modular machine tools, and obtained 17 patents, becoming one of the largest manufacturers of multi-spindle drilling machines in China.
