Stainless steel is a high-alloy steel, which usually contains elements such as chromium, nickel, and molybdenum. These elements give stainless steel excellent corrosion resistance and high-temperature strength. However, these characteristics also make stainless steel cutting particularly difficult. Stainless steel has a high hardness, and the tool wears quickly during cutting, requiring frequent tool replacement, which increases the processing cost. Stainless steel has poor thermal conductivity, and the heat generated during the cutting process is difficult to dissipate quickly, which can easily lead to tool overheating and thermal deformation of the workpiece, affecting the processing accuracy. Stainless steel has a large cutting force and is prone to vibration, which further aggravates the problems of tool wear and workpiece deformation.

In view of these cutting characteristics of stainless steel materials, the long-shaft milling and turning composite processing machine tool has been optimized in design to ensure extremely high stability and precision during high-speed cutting.

High-precision, high-rigidity spindle system: The spindle system of the long-axis milling and turning composite processing machine tool adopts high-precision bearings and precise transmission mechanisms to ensure the stability and precision of the spindle under high-speed operation. At the same time, the high-rigidity design of the spindle system can effectively resist the vibration and deformation generated during the cutting process, ensuring the stability and precision of the processing process. This design not only extends the service life of the tool, but also reduces the surface damage of the workpiece caused by vibration and improves the processing quality.
Advanced cooling and lubrication system: In order to cope with the heat generated during the cutting process of stainless steel, the long-axis milling machine is equipped with an advanced cooling and lubrication system. The system can take away the heat in time during the cutting process, reduce the temperature of the tool and the workpiece, and prevent thermal deformation and overheating of the tool. At the same time, the lubrication system can also reduce cutting force and friction, further extend the life of the tool and improve processing efficiency.
Intelligent tool management system: The long-axis milling machine integrates an intelligent tool management system, which can automatically select the appropriate tool according to the processing material and process, and automatically adjust the cutting parameters according to the tool wear. This intelligent tool management not only improves the processing efficiency, but also ensures the consistency and stability of the processing process, and avoids the decrease in processing accuracy due to tool wear.
Online monitoring and adaptive control: The long-axis milling machine is equipped with high-precision sensors and adaptive control systems, which can monitor various parameters in the processing process in real time, such as cutting force, vibration, temperature, etc. When an abnormal situation is detected, the system can automatically adjust the processing parameters to ensure the stability and accuracy of the processing process. This online monitoring and adaptive control enables the long-axis milling machine to maintain extremely high processing quality and efficiency when facing difficult-to-process materials such as stainless steel.

In the automotive manufacturing industry, stainless steel precision parts such as engine cylinders, crankshafts, transmission gears, etc. have extremely high requirements for processing accuracy and surface quality. Long-axis milling machine tools have been successfully applied to the processing of these parts with their high-precision, high-rigidity spindle systems and a series of advanced technologies. For example, in the processing of engine cylinders, long-axis milling machine tools can complete the precision processing of cylinder holes, water channels and oil channels at one time, ensuring the dimensional accuracy and surface quality of the cylinder body and improving the performance and reliability of the engine. In the processing of crankshafts and transmission gears, long-axis milling machine tools can accurately control the tool's motion trajectory and cutting parameters, ensuring the gear tooth profile accuracy and surface roughness, and improving the gear shifting smoothness and power transmission efficiency of the transmission.

As the manufacturing industry develops towards intelligence, efficiency and greenness, long-axis milling machine tools will play an increasingly important role. In the future, long-axis turning-milling machine tools will pay more attention to technological innovation and intelligent development, such as introducing technologies such as artificial intelligence and big data to achieve intelligent optimization and predictive control of the machining process. With the continuous emergence of new materials and new processes, long-axis turning-milling machine tools will also continue to upgrade and improve to meet more complex and diverse machining needs.
