Slurry pump, as one of the main equipments in the mining, electric power, metallurgy, coal and other industries, is commonly used to transport slurry containing corrosive solid particles, which is required to have high wear resistance and corrosion resistance.
Casting-formed slurry pump parts have casting defects on the surface of the blank, and the slurry pump impeller is an interrupt cutting condition, which requires higher performance of the cutting tool.
When the conventional carbide tool processing slurry pump, there are often problems such as severe wear, frequent tool change, which affects production efficiency and product quality. At this time, Halnn solid CBN tool is selected, which not only can rough turning slurry pump blank with large allowance, but also has long tool life, reduce the frequency of tool change and improve production efficiency.
The following is a detailed introduction to the CBN grade and cutting parameters of the Halnn CBN tool processing slurry pump.
