Embodiment Construction

[0009] in figure 1 In the process, the machining part 1 and the machining tool 2 are cut in an environment with low oxygen content created by the vacuum pump 3 and the cutting area 5, and the enclosed space 6 is isolated from the environment 4. The corresponding suction port 7 of the vacuum pump and the machining surface 8 of the corresponding part are continuously evacuated quantitatively to maintain the corresponding vacuum low oxygen state.

[0010] in figure 2 In the illustrated embodiment, during the cutting process of the machining tool 2 on the machining part 1, the oxygen content index of the cutting area 5 and the enclosed space 6 is high and low, which affects the service life and cutting force of the machining tool 2 and the quality of the machining surface 8 Obviously. The present invention has tested the cutting of steel materials through two implementation methods:

[0011] Use non-alloy steel C45 as the processing material, super alloy P (10…30) as the tool materi...

Abstract

Traditional metal cutting is carried out in air, the local oxygen-content index of a cutting area has greater influences on the service life and the cutting force of a machining tool, and oxygen is the main factor of tool and part oxidative wear, so that the oxygen is quantitatively controlled in the local cutting area. The invention provides a method for prolonging the service life of the tool and reducing the cutting resistance in metal cutting. A cutting environment with the low oxygen content is manufactured in the cutting area through a vacuum pump, a low-oxygen environment for metal cutting is manufactured by reducing the oxygen in the state of local high temperature generated in cutting, the life cycle of a cutting tool is prolonged by more than ten times in the low-oxygen environment (the oxygen content is 10 percent of the usual oxygen content of the air) through a closed space or a semi-closed space, the machining precision is improved, and the negative influence on the surface of a cutting workpiece is reduced.

Description

Technical field [0001] The present invention relates to "a method for improving tool life and reducing cutting resistance in metal cutting processing". Background technique [0002] As we all know, in the metal cutting process, cooling and lubricating aids, such as lubricating oil, coolant, and liquid carbon dioxide (liquid or gas) are usually injected into the machining area to reduce cutting force, improve machining accuracy and cutting tool life. Liquid or gaseous auxiliary substances, such as air, gaseous nitrogen, oxygen or carbon dioxide, metal cutting cooling lubricants, etc., act on the actual cutting area from different directions in the form of atmospheric pressure or high pressure. There are usually some uncertain negative effects, such as: auxiliary substances cannot act on the cutting area in a timely and accurate manner, and chemical reactions between auxiliary substances and cutting tools and cutting objects will cause contamination to cutting tools, cutting object...
