Classification of sawing machines

Circular sawing machine

The circular saw blade rotates for cutting, and simultaneously feeds with the saw box. The circular sawing machine is divided into three types according to the feed direction of the saw blade: horizontal (horizontal feed), vertical (vertical feed) and swing (swing feed around a pivot). In addition, there are various special circular sawing machines, such as the shaking head sawing machine used to cut the gating and riser of large castings; Saw drill combined machine tool for rail sawing and drilling.

Band sawing machine

The circular saw belt is tensioned on two saw wheels, and the saw wheel drives the saw belt to cut. There are mainly two types of band sawing machines: vertical and horizontal. The saw frame of the vertical band sawing machine is vertically set. When cutting, the workpiece moves to cut the curve contour of the sheet metal and formed parts. The saw band can also be replaced with a file chain or abrasive belt for filing or grinding. The saw frame of the horizontal band sawing machine is horizontally or obliquely arranged, feeding along the vertical direction or the direction of swinging around a fulcrum. The saw band is generally twisted by 40 ° to keep the saw teeth perpendicular to the workpiece. The horizontal type is also divided into scissors type, double column type and single column type band sawing machines; It can be divided into manual type (economical manual feeding and manual cutting) and automatic type according to the usage; According to the automatic program using the controller, it can be divided into manual type (semi-automatic manual feeding) and automatic type (automatic feeding and automatic cutting); According to the cutting angle requirements, it can be divided into angle sawing machine (capable of sawing angle of 90 ° 45 °), no angle, i.e. 90 ° vertical cutting.

Hacksaw machine

The saw bow with saw blade reciprocates and feeds by swinging the saw frame around a fulcrum. The machine tool is simple in structure, small in size, but low in efficiency. There are two kinds of motion tracks of the hacksaw blade: straight line and arc. When the arc moves, the saw bow swings a small angle around a fulcrum. The cut in amount of each saw tooth is large, the chip removal is easy, and the efficiency is high. Most new hacksaw machines use this method.
