For compressor processing enterprises, CBN tools with low production cost and high processing efficiency have become the main choice to replace cemented carbide cutting tools. However, when processing compressors, due to the wide variety of compressor components, CBN tool manufacturers are uneven. , The selection of CBN tools has become a difficult problem for many companies. Today, the author will combine his own research data and feedback from processing compressor companies to talk about how to choose the most efficient CBN tools when processing various gray iron castings for compressors.

As the most important part of air conditioners, processing compressors has always been the top priority of manufacturers, especially sealing plates (flanges) that require mass production, which will generate a lot of cutting during high-speed, high-volume processing In addition, the gray cast iron material often has defects such as hard spots, sand inclusions, and pores, and the working conditions are slightly complicated. Although CBN tools rely on their high hardness, high heat resistance, and high A series of advantages such as chemical inertness perfectly make up for the shortcomings of cemented carbide tools. However, due to differences in the manufacturing process and raw material quality of CBN tool manufacturers, the life of CBN tools is also different.

After investigation, the tool life of CBN tool BNK25 tool is significantly improved under the same working conditions, which should be the reason why the CBN tool is popular in the market for processing gray iron castings for compressors.

BNK30 grade CBN tools can process gray iron castings at a high speed at a cutting speed of 600-2000m/min, and can still work normally at a high temperature of 1000°C, especially in the field of finishing. The life and stability of BNK30 grade CBN tools 50% higher than homogeneous products, or even higher.

As the mainstream CBN tool for processing gray iron castings of compressors, Hualing BNK series tools stand out from the crowd of CBN tools with a series of excellent performances, occupying the field of processing gray castings such as compressor cylinders, upper bearings, and sealing discs. There is a huge market, but Valin is still working hard on the solution of machining the compressor's overall tool.

Speaking of this, when processing gray iron castings for compressors, how to choose the most efficient CBN tool, I think everyone has a simple understanding. The processing cylinder can be selected with CBN tool BNK30 grade, and the processing of upper bearings and sealing plates (flanges) can be selected. BNK25 can help you improve processing efficiency and reduce production costs in minutes.
