The quasi-dry cutting technology combines the compressed gas with a very small amount of lubricating fluid and then ejects it into the processing area to effectively lubricate the processed part between the tool and the workpiece. It can greatly reduce the friction between “ tool -workpiece†and “ tool -chipâ€, which can suppress the temperature rise, reduce the tool wear, prevent the adhesion and improve the processing quality of the workpiece. The lubricating fluid used is very small, but the effect is very Significantly, it not only improves work efficiency, but also does not pollute the environment. This is why it is getting more and more people's attention. Quasi-dry cutting uses very little lubricant, typically 0.03 to 0.2 L/h, while a typical machining center uses up to 20 to 100 L/min of cutting fluid for wet cutting. Moreover, as long as the MQL technology is used properly, the processed tools , workpieces and chips are dry, avoiding the later processing, eliminating the need for a cutting fluid recovery device, and the clean and clean chips can be recycled after being compressed, completely non-polluting. surroundings.
Application of quasi-dry cutting system (MQL) in copper and aluminum processing
First, the main application:
1. Aluminium factory copper factory aluminum rod, copper rod cutting sawing
2. Various specifications of aluminum and copper ingots (saw cutting)
3. Various types of ingot milling (single and double-sided milling)
4. Profile cutting (saw cutting) after extrusion
5. High-gloss cutting of all kinds of precision alloy parts (after heat treatment ), turning, drilling, tapping.
Second, the advantages:
1. Copper and aluminum scraps are dry and free of impurities, and can be directly smelted and smelted, eliminating many expenses. Eliminate many post-processing steps, equipment, such as cleaning, baking chips, eliminating the need for crumbs, and reducing the amount of burning energy consumption
2. Tool life is extended by more than 2-3 times, reducing tool cost and forming a super-lubricating oil film on the cutting edge. The chip does not stick to the knife, the cutting edge and the workpiece are directly contacted and the friction is reduced to a minimum, and the tool basically maintains the room temperature during the cutting process.
3. The processing efficiency is increased by more than 50%, and the speed and feed can be greatly improved. Reduce tool change and maintenance time and increase cutting speed
4. Environmentally safe and harmless to the human body. Greatly improve the original environment of the site, reduce the dry cut of copper and aluminum chips, and eliminate the health problems caused by the wet processing of emulsions, such as splashing, evaporation, odor and allergies.
Third, the principle of action
The micro-lubrication system uses high-speed jetted compressed air to precisely spray the super-lubricating vegetable oil-based cutting oil on the cutting edge and the friction-generating part, forming an oil film between the tool and the workpiece to minimize stress concentration deformation. And the heat generated by friction, in addition, high-speed compressed air blows away some of the heat and debris. High-speed compressed air blows out the oil without atomization, so the oil and gas mixture does not spread into the production environment. The oil film has super strong adhesion and will not be thrown away by the centrifugal force of high-speed rotation.
