    • A rotary disc cutter for cutting workpieces, especially gears and the like. The rotary cutter comprises a plurality of cutting blades arranged about the periphery of a rotary disc cutting body with at least a portion of the blades being roughing blades comprising a tip and two sides with each side having first and second side portions. The first side portion along with the tip defining a cutting surface of the blades while the second side portion is relieved such that a clearance is formed between the second side portion and the surface of the workpiece. The clearance being of a dimension to allow the flow of coolant therethrough thereby improving the cooling of the cutting surface and enhancing the flow of chips away form the vicinity of the blades. The invention further includes a substantially reduced number of blade segments. Alternative blade tip configurations are also disclosed.
    • 一种用于切割工件,特别是齿轮等的旋转盘式切割机。 旋转切割机包括围绕旋转盘切割体的周边布置的多个切割刀片,其中至少一部分刀片是粗刀片,其包括尖端和两侧,每侧具有第一和第二侧部。 第一侧部分与尖端一起限定叶片的切割表面,同时第二侧部被释放,使得在第二侧部和工件的表面之间形成间隙。 该间隙具有允许冷却剂流过的尺寸,从而改善切割表面的冷却并且增强切屑从叶片附近的流动。 本发明还包括大量减少数量的叶片段。 还公开了替代的刀片尖端配置。
