Much of what is produced by human activities currently being done on machine tools or with machines manufactured by using such machines. Their range is very wide – from grinding machines with manual operation to computerized systems and robotizovannyh. Almost all types of machines are available with manual control, and in the form of CNC. The cutting tool of a particular type (blade, cutter, etc.) does machined (metal, plastic, ceramic) chips products in much the same as it is to clean the potatoes with a knife. Cutting tool material should be much more solid and durable, than the material of the workpiece. Cutting machines for metal cutting and are designed for cutting of long products (rods, angles, channels, beams). Cutting tools are segmented circular saw, abrasive wheels or saw blades. The main motion – the rotation of the disc or reciprocating saw blade.
Automatic stamping machines for metal working at different speeds, are equipped with devices workpiece and the periodic systems of two-coordinate control of the desktop. Saber saw – a metal-cutting machine split, the working body of which is the saw blade. Used for cutting (cut) pieces perpendicular or at an angle to its axis. Reciprocating saw blades drive the majority – from the electric motor through a mechanical transmission. Distinguish reciprocating saws and vertical stankigorizontalnym working body, with a rotating frame. On modern machines, manufactured in Europe as a tool increasingly used circular band saws (such machines are called cut-off band saw machine column or the pendulum types).
Manual band saws are used for procuring small volumes of production in machine shops small and large businesses, as well as repair and installation workshops. As a rule, they are characterized by hand in a vise clamping machine, a hand saw frame by reducing the initial upper position, manage the process of sawing by hand. Bandsaws this group can be equipped with optional electronic control system speed bandsaw blade on pulleys, coolant spraying device and roller tables. In the event that the customer is required sawmill, which will run continuously during the entire shift, producing a cut every few minutes, it is recommended to purchase semi-automatic.
