The MCZ series CNC machine is composed of two sections, bus punching unit and bending unit. It is developed by absorbing the features of the similar products abroad based on the actual situation concerning bus production in China. So far, the products have been put into use in a number of domestic enterprises, such as Beijing Switchgear Factory, Tianshui Great Wall Switchgear Factory, Xi' an High Voltage Switchgear Company Limited, Jiangsu Changjiang Electric Appliances Company Limited, Wenzhou Zhengtai Group, Shanghai Delixi Group, Shanghai Fuji Electric Motor and Guangzhou Baiyuan Electrics.

A. The punching unit can realize punching, channeling, edging, cornering, shearing and rouletting. It is equipped with six station tool box, simple in structure and convenient for removal. The die material is of alloy steel with long service life. The dies are aligned linearly, and the base is made integratedly by the processing center, thus ensuring the coaxiality of the die and enhancing their service life.

B. The different pneumatic clamps are optional based on the customers' requirement. The clamp travels along X Axis at one stroke of 1000mmm and maximum stroke up to 6000mm.

C. The bending unit can realize the horizontal bending, vertical bending, U bending and distorting of bus with powerful function, high accuracy and stable performance.

D. The bending unit adopts a unique electronic cavity die. The bending angle is measured and bending error compensated automatically with the measurement accuracy within 0.10 and bending accuracy within 0.30. The processing accuracy, especially repetitive accuracy is up to a very high standard.

E. The punching unit adopts the advanced CNC and drive system, with field and background programming, and graphic simulation functions. It also has RS232 standard port. The bending unit adopts the high level industrial control computer with color graphic simulation and automatic angle compensation for precise control of backguage.

F. The punching and bending units both utilize hydraulic main drive. The pneumatic, hydraulic and electric components are world famous brands, featuring reliable quality and stable performance.

G. The high precision ballscrew and linear guideway in the transmission system are world famous brands, featuring high positioning and moving accuracy.

H. Two machinery adopt different hydraulic and CNC systems, which can either be combined or controlled separately to meet different customer requirements.

J. The machine features high flexibility, adaptable to different products. Whether it is a small lot with a variety of products, or it is large batch production, the customer requirement can be easily met. It is now widely used in modern bus processing.
