我所在利用粉末冶金法制作耐腐蚀钦钼合金球阀时,为车制阀芯球体,研制了一种车制球体的自动回转刀架。这种刀架的结构简单、体积小、装拆和使用均较方便,可作为一种附件直接安装在普通车床上。用此刀架加工球体时,其工作效率、加工精度和工件表面光洁度都较用样板刀或手工剥圆法有显著提高。例如阀芯的图纸尺寸为球φ42±0.04mm时,实测得阀芯尺寸为球φ42±0.02mm;表面光洁度可达 7;工效提高5倍以上。且它采用普通车刀,易于修磨,车床也不
I am using the powder metallurgy law making corrosion-resistant Chin-molybdenum alloy ball valve for the car system ball, developed a car ball automatic rotary turret. This tool holder has the advantages of simple structure, small size, convenient assembly and disassembly and use, and can be directly mounted on an ordinary lathe as an accessory. With this turret processing sphere, its work efficiency, machining accuracy and workpiece surface finish than with a sample knife or hand stripping method has significantly improved. For example, when the size of the spool is ball φ42 ± 0.04mm, the measured spool size is ball φ42 ± 0.02mm; the surface finish is up to 7; and the work efficiency is increased by 5 times. And it uses ordinary turning tools, easy grinding, lathe is not
