Lathe process—One Kind Of CNC Machining Process

Lathe processing is a part of mechanical processing, and there are two main processing forms: one is to fix the turning tool to process the unformed workpiece in rotation; the other is to fix the workpiece, and through the high-speed rotation of the workpiece, the turning tool (tool holder) ) horizontal and vertical movement for precision machining.
On the lathe, drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with revolving surfaces, and are the most widely used type of machine tool in machinery manufacturing and repair factories.
The materials commonly used in modern lathe processing use aluminum alloy materials. The density of aluminum alloy materials is greatly reduced compared to the density of iron and steel materials, and the lathe processing difficulty is low, the plasticity is strong, the product weight is greatly reduced, and the lathe processing parts are greatly shortened. The time comes with the reduction in cost making aluminum alloy the darling of the aviation accessories field.
Lathe process:
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 axis of rotation, so it is easy to ensure the coaxiality between the processing surfaces;
2. The cutting process is relatively stable; except for the interrupted surface, the lathe machining process is generally continuous, unlike milling and planing, in the process of one pass, the cutter teeth are cut in and out many times, resulting in shock;
3. It is suitable for the finishing of non-ferrous metal parts; for 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 by other processing methods;
4. The tool is simple; the turning tool is the simplest kind of tool, and it is very convenient to manufacture, sharpen and install, which makes it easy to select a reasonable angle according to specific processing requirements.
