When selecting the cutting amount for CNC vertical lathes, we must fully consider the various factors that affect the cutting, correctly choose the cutting conditions, and determine the reasonable cutting amount, so that the machining quality and output can be effectively improved. Tool setting and tool setting are very important and very difficult basic tasks in vertical lathe processing. The quality of tool setting and tool setting will directly affect the programming of the processing program and the dimensional accuracy of the parts. Only by mastering the tool installation and tool setting technology can the processing quality be guaranteed. Knife setting is generally divided into two categories: manual tool setting and automatic tool setting. At present, most of the machine tools adopt manual tool setting, and the commonly used method is the trial cutting tool setting method, which can obtain more accurate and reliable results.
The conditions that affect the cutting efficiency of CNC vertical lathes mainly include:
1. The rigidity of the vertical lathe bed, cutting tool and workpiece;
2. Cutting speed, cutting depth, cutting feed rate;
3. Workpiece accuracy and surface roughness;
4. Tool life expectancy and maximum productivity;
5. Types of cutting fluids and cooling methods;
6. The hardness and heat treatment of the workpiece material;
7. The number of workpieces and the life of the machine tool.
