Problems solved by technology

Therefore, the poor processability, low cutting efficiency and high tool consumption of high-alloy and high-hardness rolls have always been problems that cannot be solved by conventional dry turning processes. At the same time, dry turning also brings dust pollution to the production site.
In recent years, technicians have continuously explored and improved tools and cutting parameters, such as the development and application of ultra-high hardness alloy tools, ceramic tools, PCBN tools, FBN tools, etc., in order to improve tool durability and processing efficiency, but limited by the limitations of dry turning technology , and the particularity of the roll material, the improvement effect is not obvious

Embodiment Construction

[0011] The atomization cutting technology of the present invention mainly includes the design of the spray mode, the preparation of the cutting fluid, the atomization processing parameters and the special atomization device. The atomized cutting process is to mix the atomized cutting fluid with compressed air in the atomizing device to form a mist jet with a certain pressure, which is sprayed on the cutting area of ​​the tool. According to the processing characteristics, there are different spraying methods, such as rake face spraying method: this method is suitable for processing brittle materials such as high nickel chromium and high chromium iron, and the chip breaking condition is good, and the atomization will not be interfered by the chip breaking problem Nozzle spray of the device; flank spraying method: suitable for forged steel cold roll materials that are difficult to break chips. Because of the flank spraying method, chip breaking will not interfere with the nozzle o...

Abstract

The invention discloses a roller atomization cutting processing manufacture technique. Wherein, it uses a special atomization device to mix the cutting solution in compressed air and form spray jet with some pressure; when turning, the jet sprays on cutting zone to cool cutting tool, lubricate the friction, increase the durable property and cutting efficiency and avoid the dust. This invention is environmental friend.

Description

Technical field: [0001] The invention relates to a roll cutting process, in particular to a roll atomization cutting process and an atomization device. Background technique: [0002] The roll is a tool for rolling metal. In order to extend the rolling time on the machine and obtain a more ideal surface quality, high-chromium and high-alloy roll materials are being widely used. The hardness of the working layer matrix of the roll body is as high as HRC60- 70, and a large number of uniformly dispersed high-hardness carbides are distributed on the hard body, which has poor thermal conductivity, difficult processing, and low cutting efficiency. When the cutting speed is about 10m / min, the cutting temperature is as high as 800℃, the hardness of the tool decreases and the wear increases. Therefore, the poor processability, low cutting efficiency and high tool consumption of high-alloy and high-hardness rolls have always been problems that cannot be solved by conventional dry turn...
