Are there any German products called K44 which are imported into cemented carbide materials? I am machining hole, K44 is better than domestic material K30?
K44 never heard of it! All I know is K40.K40 is better than K30, but almost stiff.K40 is suitable for rough machining, and K30 is suitable for finish machining.It's better to process K40 holes in general.
Germany never heard of K44, I know K40 is the international organization for standardization as the equivalent of the national standard YG-10H, the hardness of about 1300HV, used for processing softwood or hardwood and nonferrous metal; K30 is equivalent to the national standard YG-8, the hardness of about 1400HV, suitable for low hardness of grey cast iron, low tensile strength steel and compressed wood.Compared with the two, K40 has higher toughness, but its wear resistance is lower.
Yes, K44 is a German cobalt collar carbide material.German cobalt collar is the world's third largest rotating cutter manufacturer, with more than 100 years manufacturingCobalt collar: metal hole cutting tool history, including in the United States, Britain, Brazil, Japan, Korea, Czech and other nineteen countries set up factories. The main production, sale and repair all kinds of metal hole cutting tools, all of its main equipment imported from germany. At present, the tool grinding, grinding and grinding center has a modern five axis CNC intelligent cutting tool grinder,The automatic coating equipment and precision universal cutting tool measuring equipment which can be coated with many kinds of coatings, is mainly responsible for grinding, grinding and grinding all kinds of high speed steel and grinding hard alloy milling cutters and hole cutting tools.
