Dual Spindle Machining Center

In high-speed dry cutting, due to the lack of lubrication, cooling, and chip removal effects provided by cutting fluids, the following issues may arise:

1. Without the lubricating effect of cutting fluids, the cutting force in high-speed dry cutting significantly increases, and the vibration between the tool and the workpiece intensifies, leading to poorer machining performance of the workpiece, accelerated tool wear, and reduced tool life.

2. The absence of cooling from cutting fluids causes a large amount of heat to be generated instantaneously during high-speed dry cutting. This heat is primarily concentrated in the cutting zone, affecting the formation of chips. Excessive high temperatures can result in the formation of long, entangled chips that wrap around the tool, impeding subsequent cutting and exacerbating tool wear. If the heat is not promptly dissipated from the main structure of the machine tool, it can cause significant thermal deformation of the machine, compromising machining accuracy and reducing the workpiece's process performance.

3. When cutting certain materials (such as graphite electrodes) in high-speed dry cutting, a large amount of dust is generated. If not promptly removed, this dust can harm the health of operators and, additionally, fine particles can infiltrate critical machine tool components such as ball screws and bearings, increasing wear on the machine tool and affecting its machining accuracy and reliability. Due to the differences in the cutting processes between high-speed dry cutting and high-speed wet cutting, to ensure stable cutting operations, the cutting parameters originally used for high-speed wet cutting must be relatively adjusted and fine-tuned for application in high-speed dry cutting. To address the aforementioned issues and achieve processing quality and tool wear resistance in high-speed dry cutting that are comparable (or even superior) to those of high-speed wet cutting within the required time frame, it is necessary to comprehensively consider and weigh all aspects of the processing system, including the machine tool, tool, workpiece, and cutting parameters, and adopt corresponding processing methods to compensate for the shortcomings of high-speed dry cutting.
