在针织机的针桶上铣槽在是针织机生产中的关键问题之一。主要的困难是每只φ700×300毫米的45号钢针桶的圆周上要铣出宽0.69毫米,深5毫米的针槽2088条。目前使用高速钢铣刀每片只能铣槽200条左右,通常至少要消耗10片以上铣刀才能加工一只针桶。并且用高速钢铣刀的切削速度低,铣一只针桶往往要一个星期。用硬质合金铣刀代替高速钢铣刀的主要困难在于铣刀的直径为70毫米,厚度仅0.7毫米左右,因此刀 One of the key issues in the production of knitting machines is the grooving of needles in knitting machines. The main difficulty is that 2088 needles of 0.69 mm in width and 5 mm in depth are machined on the circumference of the 45 # needle barrels of φ700 × 300 mm each. The current use of high-speed steel milling cutter can only mop about 200 each, usually consume at least 10 or more milling cutter to process a needle barrel. And high-speed steel milling cutter cutting speed is low, milling a needle bucket often takes a week. The main difficulty of replacing a high speed steel cutter with a carbide cutter is that the cutter has a diameter of 70 mm and a thickness of only about 0.7 mm,
