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。
