Factors Affecting the Cutting Efficiency of Turning-milling Compound CNC Lathe

The cutting efficiency of turn-milling compound CNC lathe will be affected by human factors, environmental factors and the machine itself. Turning and milling composite CNC lathe manufacturers, what factors will affect the machine tool processing.

1. The frequency and location of the operation are unreasonable.

Turning-milling composite machine tools are used in mass production, especially in mass production. Under the premise of ensuring the processing quality, improving the processing efficiency and ensuring the stability of the processing process are the basis for obtaining good economic benefits. Choosing a simple tool change method is an effective way to reduce tool change auxiliary time, reduce machine tool wear and reduce processing costs when CNC turning batch processing. One of the effective attempts to achieve this goal is to improve the setting of the tool change point of the turn-milling composite machine tool. Therefore, it is necessary to carefully analyze, optimize and improve the design in terms of fixture selection, tool rail arrangement, tool row position and use sequence.

2. Unreasonable cutting amount

Reasonable cutting parameters can improve the machining efficiency of turn-milling compound machine tool. When the cutting speed is increased by 10 times and the feed speed is increased by 20 times, far beyond the "forbidden zone" of traditional cutting, the cutting mechanism has undergone a fundamental change. The results show that the metal removal rate per unit power is increased by 30-40, the cutting force is reduced by 30, the cutting life of the tool is increased by 70, the cutting heat remaining on the workpiece is greatly reduced, the cutting vibration is almost disappeared, and the cutting process has achieved an essential leap. According to the current situation of CNC turn-milling compound machine tools, increasing the feed per tooth can improve productivity and tool life.

3. Selection of cutting tools

The selection of cutting tools is an important link to ensure the processing quality and improve the processing efficiency. In order to improve productivity, CNC machine tools, especially turning and milling, are developing in the direction of high speed, high rigidity and high power. This requires the tool to have the ability to withstand high-speed cutting and cutting, performance to be stable. When selecting tool materials, when the processing conditions allow the selection of carbide tools, high-speed steel tools should not be selected. Conditionally select tools with better performance and wear resistance, such as coated tools, cubic nitride tools, ceramic blades, etc.
