将需要加工的齿轮齿槽部份按置在卡盘上的圆柱体或球形体上(滚柱及滚珠),这些滚柱及滚珠可与齿顶曲线面箱接触,这样被加工孔与齿冠之间便可以保持同心状态。 如为正齿轮时,像这样的夹紧用圆柱头可以采用滚柱,如为斜齿轮或拿齿轮时,则可采用滚珠。 材料:20X号钢;渗炭,淬火,HRC=5 Will need to be processed gear cogging part of the press on the cylinder on the chuck or spherical body (roller and ball), these rollers and balls can be crest contact surface box, so that the processing hole and crown You can maintain a concentric state. In the case of a spur gear, a roller such as a cylinder head for clamping may be used, for example, a helical gear or a gear, a ball may be used. Material: 20X steel; Charging, quenching, HRC = 5
