drills, reamers, reamers, taps, dies and knurling tools can also be processed on the lathe. Lathe is mainly used for processing shaft, disc, sleeve and other rotating surface of the workpiece, is the most widely used machine tool processing type in machinery manufacturing and repair factory. The materials usually processed by the
lathe are free-cutting steel and copper. Free cutting steel contains high sulfur S and phosphorus P. Sulfur and manganese are present in steel in the form of manganese sulfide, which is present in the form of manganese sulfide.
The commonly used material for modern lathe processing is aluminum alloy material. The density of aluminum alloy material is much lower than that of steel material, the lathe processing difficulty is small, and the plasticity is strong. The weight of the product is greatly reduced, and the lathe processing parts are greatly shortened. Over time, the cost continues to decrease, making aluminum alloys the darling of the aerospace parts world.
1. It is easy to ensure the accuracy of each processing surface of the workpiece; during processing, the workpiece rotates around a fixed axis, and each surface has the same rotation axis, so it is easy to ensure the coaxiality requirements between the processing surfaces;
2. The cutting process is relatively stable; Except for intermittent surfaces, the lathe processing process is generally continuous, which is different from milling and planing. During one pass, the teeth are cut in and out many times, resulting in impact;
3, suitable for the finishing of non-ferrous metal parts; some non-ferrous metal parts, due to the low hardness and good plasticity of the material itself, it is difficult to obtain a smooth surface with other processing methods;
4, the tool is simple; the turning tool is the simplest tool, easy to manufacture, sharpen and install, this makes it easy to select a reasonable angle according to the specific processing requirements.
