sector-focusing machine

During cutting gear sectors on this machine, the cutter performs vertical reciprocating motion only, while the workpiece ( gear sector) performs both rotary motion and variable speed tangential displacement, i. e. the cutting is performed by variable speed generating motion.

该机床在切削齿扇时，梳刀只作上下往复运动，工件（齿扇）既作圆周运动又作变速切向移动，即在变速范成运动中完成加工的。

Intermitten constuction of toothed sector conjugate cam ensures machine accurate and lower noise at high speed.

扇形齿轮共轭凸轮的间隙机构冲击小、刚性好、噪声低,确保机器在高速运转时的模切精度.
