In CNC lathe machining parts, the process should generally be divided according to the principle of process concentration, and the processing of most or even all surfaces should be completed as much as possible under one clamping. According to the different structural shapes of the parts, the outer circle, the end face or the inner hole is usually selected for clamping, and the unity of the design basis, the process basis and the programming origin is guaranteed as much as possible. Next, Hongweisheng Precision Technology Co., Ltd. will explore the division of cnc CNC lathe processing procedures with you.
In mass production, the following two methods are commonly used to divide the process.
1. According to the machining surface of the parts. Arrange the surfaces with high positional accuracy requirements in one clamping to avoid the installation error caused by multiple clampings from affecting the positional accuracy.
2. According to roughing and finishing. For parts with large blank allowance and high machining accuracy requirements, rough turning and fine turning should be separated into two or more processes. Arrange the rough turning on the CNC lathe with lower precision and higher power, and arrange the fine turning on the CNC lathe with higher precision.
The division of CNC lathe processing procedures mainly considers the production program, the structure and technical requirements of the equipment used and the parts themselves. In mass production, if a high-efficiency machining center with multi-axis and multi-tool is used, the production can be organized according to the principle of process concentration; if it is processed on an automatic line composed of combined machine tools, the process is generally divided according to the principle of dispersion.
