lathe machining

Lathe processing is the 1 common metal processing method, which uses the lathe machine to fix the metal material on the machine tool and process it by rotating the cutting tool. Lathe processing has a wide range of applications, including aerospace, automobile manufacturing, electronic products, etc.

The process flow of lathe processing generally includes the 5 steps: workpiece clamping, coordinate system setting, process parameter setting, cutting processing, workpiece quality inspection.

Workpiece clamping is the first step in lathe processing, which determines the position and attitude of the workpiece in the processing process. There are many ways to clamp, the most common are elastic clamping and hard clamping. When the workpiece is clamped, it is necessary to ensure the stability and rigidity of the workpiece to avoid deformation or separation from the clamping table during processing.

Coordinate system setting is the second step of lathe processing, it is to determine the relative position and direction of the lathe coordinate system and the workpiece coordinate system. In the lathe processing, generally using rectangular coordinate system, in order to facilitate the calculation and control.

Process parameter setting is the third step of lathe processing, which includes the selection and setting of cutting speed, feed speed, depth of cut and other parameters. The choice of these parameters needs to be determined according to factors such as workpiece material, machining form and tool type. When setting the process parameters, it is necessary to pay attention to the reasonable collocation to ensure the stability and quality of the processing process.

Cutting is the core step of lathe processing, it is the use of cutting tools for metal cutting, cutting and trimming. Cutting tools are commonly used in: turning tools, milling cutters, boring cutters and drill cutters. The choice of tool depends on the shape of the workpiece and the processing requirements. The cutting process can be divided into 3 stages: rough cutting, semi-finishing cutting and precision cutting. The cutting requirements and machining accuracy of each stage are different.

Workpiece quality inspection is the last step of lathe processing, it is to check whether the processing quality meets the requirements. Workpiece quality inspection methods include visual inspection and precision measurement. Visual inspection is to judge the quality of the workpiece by observing whether there are scratches, burrs, cracks and other defects on the surface of the workpiece with the naked eye. Precision measurement is through the use of precision measuring tools such as micrometer, outside diameter gauge and other tools to detect the workpiece size accuracy, shape tolerance and other indicators.

Lathe processing has many advantages, such as: processing speed, high precision, high production efficiency, good repeatability. However, there are also some challenges in lathe processing, such as: difficult clamping of workpieces, tool wear, excessive cutting heat, etc. In order to solve these problems, it is necessary to reasonably select the tool and process parameters, and carry out the necessary cooling and lubrication.

All in all, lathe processing is the 1 important metal processing method, it is widely used, has many advantages. Through reasonable process flow and process parameter setting, high-quality metal processing can be achieved.
