cutting is a kind of mechanical processing, and it can be divided into turning, drilling, boring, milling, planing, ploughing and broaching. Cutting is a machining process that uses a cutting tool to cut off the redundant material from the workpiece to obtain the geometry, size and surface quality that is in line with the requirements of the drawing.
cutting is one of the important methods of mechanical manufacturing. It is the main means to improve the dimension precision and surface quality of the parts. It occupies a very important position in the machinery manufacturing industry, accounting for the 40%-60% of the total mechanical manufacturing quantity. The cutting process is generally not limited to the shape and size of the parts. It can be machined, such as the outer circle, the inner circle, the cone, the plane, the thread, the tooth surface and the space surface.
turning refers to the machining method of turning the main part of the workpiece and turning the tool into feed. Turning processing is mainly used to process the rotary surface and can process the plane, and the two kinds of surfaces are most widely used in the mechanical parts. Therefore, turning is the most common processing method
used in the machining method.
because of continuous machining process, the cutting layer has a constant cross section of the cutting layer, the cutting force is not changed, the cutting process is stable, so the machining precision is higher. And the turning processing can be processed out of the outer round surface, the inner circle surface, the cone surface, the step surface and the end face. Therefore, the precision of the machining surfaces can be ensured by the precision of the lathe itself.
the turning machining is always in contact with the workpiece in the general condition, and there is no impact phenomenon. It can be cut with very high cutting parameters, so the productivity is high. Moreover, turning processing is suitable for many kinds of materials, various surfaces, large size ranges and Accuracy grades. Therefore, the processing range is wide.
