我厂为了自我武装,曾于1970年制造了一台y54 插齿机。在制造中发现让刀机构比较复杂,且有机械振动,撞击声大,易磨损,调正困难(让刀距离S=0.5毫米)等缺点。因此改用液压射流让刀。经过近两年使用证明,用射流让刀不但克服了上述缺点,而且工作可靠,工件加工精度与光洁度也有所提高 I plant in order to self-armed, had in 1970 manufactured a y54 gear shaper. Found in the manufacture of knife to make more complex institutions, and mechanical vibration, percussion sound big, easy to wear, adjust the difficulties (knife distance S = 0.5 mm) and other shortcomings. So switch to hydraulic jet to knife. After nearly two years of use of proof, with a jet knife not only overcome the above shortcomings, but also reliable, workpiece machining accuracy and finish has also been improved
