Root cutting device for turbine machining

The invention provides an undercutting device for turbine machining, which comprises a cutter disc and a cutter holder, the cutter disc is movably connected with the cutter holder, and the device can comprehensively control the cutting depth and position during turbine machining, so that the design shape of a turbine and the undercutting position are not limited any more, the consistency of products is ensured, and the production efficiency is improved. The working efficiency is effectively improved, the turbine cut through the turbine root cutting method does not affect the power of a motor when working at the low wind speed, the rotating speed of the turbine can be reduced at the high wind speed, and therefore the risk that turbine blades are broken is reduced. 本发明提供了一种涡轮加工用根切装置，包括切刀盘、切刀座，所述切刀盘与切刀座之间活动连接，本装置在涡轮加工时能够对切割深度与位置做到全面控制，使得涡轮设计形状和根切的位置不再受到限制，保证了产品的一致性，有效的提高了工作效率，使用本涡轮根切方法切割后的涡轮，在低风速下工作不会影响电机的功率，高风速下能降低涡轮转速，从而降低了涡轮叶片断裂的风险。
