Precision machinery parts processing from the breakthrough in the traditional method on stainless steel, heat-resistant steel, titanium alloy is hard processing material, because their material has many advantages, with the development of science and technology and industrial production, they are more and more applied in precision machining
industry, used to make all kinds of precision parts.
Under this situation, it puts forward higher requirements for machining technology.
Implementation machinery parts precision machining way basically has two kinds: one kind is using high precision machine tools, such as CNC lathe, CNC milling machine, precision machinery parts processing;
The other is on the basis of the traditional processing, explore new precision machining technology, in order to improve the material workability, thus improve the precision machinery parts processing precision and efficiency.
New methods mainly include error compensation control of ultrasonic vibration cutting technology, processing technology, etc.
In ordinary cutting, the cutting is done by the relative motion of the cutting tool and workpiece.
Chip and precision parts machined surface formation, nature is the extrusion by cutting tool, workpiece material produce elastic deformation and plastic deformation, make the chip and maternal separation process.
In this ordinary cutting, the cutting tool has not left the role of cutting tool includes two aspects: one is the role of the blade: one is formed on the surface of the blade of the knife.
Due to the blade to cut contact in the partial pressure is very big, so that the separation is cut.
Dao side while cutting is cut through crowded, promote this separation.
In ordinary cutting, accompanied by the formation of chip, due to the effect of extrusion and friction between chip and tool, will inevitably produce larger cutting force, high cutting temperature and tool wear and produce harmful phenomena, such as cutting vibration cutting vibration but also has its good side: cutting power under certain conditions can reduce 15
30%, chip to shrink significantly decreases, and improve the formation of cutting conditions, get broken off scraps, etc.
Based on this idea, a new method of cutting -
Vibration cutting, vibration cutting is to pass on the cutting tool on the vibration of a regular, controllable, result in periodic changes of cutting velocity, cutting depth, and special methods of cutting effect is obtained.
Changed vibration cutting tools and precision parts processed material space - between
Time existence conditions and change the mechanism of precision machining, to reduce the cutting force, cutting heat, to enhance the quality and efficiency of machining.
