The main characteristic of high chromium cast iron is that it has higher wear resistance than alloy steel, much higher toughness and strength than ordinary cast iron, and its thermal conductivity is poor, cutting force is large, cutting temperature is high, and ordinary tools are difficult to process.[url=]Precision Cold Drawn Seamless Steel Pipe With Bright Surface[/url]
For machining high chromium cast iron, there are three common tools: cemented carbide tool, ceramic tool and CBN cubic boron nitride tool. Machining high chromium cast iron with cemented carbide has rapid tool wear and can not be processed normally; The service life of cast iron tool is short, and the ceramic tool is easy to collapse.
Therefore, it is recommended to use CBN tool to process high chromium cast iron. Because of its high red hardness, it is more wear-resistant than ceramic tool materials. Higher cutting speed can be selected to obtain better machining surface quality.[url=]manufacture etched bronze mirror stainless steel sheet for kitchen utensils[/url]
For example, CBN cutting tools of bts2800 brand and sngn1608 model are used to process the pump shell of high chromium cast iron slurry pump. The recommended cutting parameters are VC = 80-150m / min, AP = 1-3mm, f = 0.25-0.5mm/r. Compared with a brand of ceramic blade, the tool life is increased by 2 times and the machining efficiency is increased by 1.5 times.[url=]cold drawn precision seamless carbon steel pipe astm sa106 gr.b[/url]
