Metal band saws are fully automatic band saws integrating mechanics, electricity, and hydraulics. They are used for sawing various profiles of ferrous and non-ferrous metals with large diameters. They have a reasonable structure and beautiful appearance. CNC lathes can be divided into two main categories: horizontal and vertical. Horizontal lathes are further divided into those with horizontal guideways and those with inclined guideways. Higher-end CNC horizontal lathes generally use inclined guideways. Based on the number of tool posts, they can be classified into single-tool-post CNC lathes and double-tool-post CNC lathes; the former uses two-axis control, and the latter uses four-axis control. Double-tool-post horizontal lathes mostly use inclined guideways.

Band saws use hydraulic cylinders, linear scales, or stepper (servo) motors to drive lead screws and racks for feeding. This allows for automatic measurement of the feeding length and calculation of the number of feeds. When the set number of sawing operations is reached, the band saw automatically stops. Automatic feeding is suitable for mass production, offering advantages such as high speed, stable sawing length, and the ability for one person to operate multiple band saws. It significantly reduces manual operation and improves production efficiency. Automatic band saw feeding machines operate automatically according to specified requirements and predetermined programs; the operator only needs to define the control requirements and program, without direct manual operation of the feeding mechanism.
