The cooling of the micro-lubrication machining mainly relies on the fluidity of the compressed air to remove the heat, which is weaker than the cutting fluid, and therefore requires the chips to quickly leave the processed area. To achieve this goal, there are several things to note: En Flanges,Carbon Welding Neck Flange,Welded Flange,Forged Steel Flanges Zhangqiu Xinhao Machinery Parts Factory , https://www.xhflange.com
1. Ensure that the compressed air pressure is stable. <br> The change in compressed air pressure leads to a decrease in the quality of the lubrication. It also reduces its auxiliary cooling effect and reduces its effect of helping the chips to leave the processing surface. Where it is not suitable for purging, a method of assisting compressed air evacuation may be employed.
2, reduce the problem of long chips in the process <br> The shape of the chip is a problem that needs to be paid attention to under the condition of micro-lubrication, it is to achieve short chips, debris, and avoid long chips. Specific measures include keeping the cutting edge sharp, researching and using a blade shape suitable for chip breaking. In the roughing process, a large amount of cutting is used to form thick short chips, and high-speed rotation is used in finishing, and a small cutting amount is obtained to obtain a good surface quality.
Principle: The heat generated by the machining will cause the temperature rise of the chips, the tool and the workpiece. The accumulation of the chips will increase the temperature rise of the tool and the workpiece. More than 80% of the heat can be quickly discharged from the workpiece through short chips and debris, which is a key factor affecting the success of quasi-dry machining.
