    Circular sawing machine
    Circular saw machine, also known as circular saw machine, is divided into fully automatic and semi-automatic. The circular saw blade undergoes a rotating cutting motion while also following the feed motion of the saw blade box (see figure). Circular saw machines are divided into three types according to the feed direction of the saw blade: horizontal (horizontal feed), vertical (vertical feed), and pendulum (swing feed around a pivot point). In addition, there are various specialized circular sawing machines, such as the shaking head sawing machine used for cutting large casting sprues and risers; Saw and drill joint machine tool for rail cutting and drilling.
    Band saw machine
    The circular saw belt is tensioned on two saw wheels and is driven by the saw wheel for cutting. There are two main types of band sawing machines: vertical and horizontal. The saw frame of a vertical band saw machine is vertically set, and the workpiece moves during cutting to cut the curve contour of the sheet metal and formed parts. The saw belt can also be replaced with a file chain or sand belt for filing or polishing. The saw frame of a horizontal band saw machine is arranged horizontally or obliquely, feeding in a vertical direction or swinging around a pivot point. The saw band is generally twisted 40 ° to maintain the saw teeth perpendicular to the workpiece. Horizontal sawing machines can be divided into scissor type, double column type, and single column type; According to usage, it can be divided into manual type (economical manual feeding and manual cutting of materials) and automatic type; According to the automation program using the controller, it can be divided into manual type (semi-automatic manual feeding) and fully automatic type (automatic feeding and automatic cutting)
    Hacksaw machine
    The saw bow equipped with a saw blade moves back and forth, feeding by swinging the saw frame around a pivot point. The machine tool has a simple structure, small volume, but low efficiency. There are two types of motion trajectories for the saw blade of a hacksaw machine: straight and curved. When moving in an arc, the saw bow swings around a pivot point for a small angle, and each tooth has a larger cutting amount, which makes it easy to remove debris and has higher efficiency. This method is mostly used in modern hacksaw machines.
