摘要
圆弧刃天然金刚石刀具是加工各类复杂曲面零件的重要工具.在其刃磨过程中,机床主轴的端面跳动严重影响刀尖圆度和刃口半径,进而影响到加工表面的完整性.基于金刚石刀具研磨机床空气静压轴承的动平衡原理,通过现场动平衡实验,能够将主轴轴向振动的最大幅值控制在0.084μm以下,从而可以刃磨出满足超精密加工要求的高质量金刚石刀具.刃磨出的金刚石刀具刃口半径值可以达到0.05μm以下,刀尖圆弧圆度提高到0.2μm以内.
The natural circular are diamond cutting tool is an important cutting tool by which the complicated curved surface parts can be machined. In lapping process, the end face run-out of grinding spindle is the leading factor affecting the radius waviness and the radius of cutting edge, which are main parameters influencing the integrity of machining surface. Through analyzing the field dynamic balancing principle of aerostatic bearing, the field dynamic balancing experiment are proceeded, the maximal swing is controlled below 0. 084 gan, and finally the high-quality tools that meet the requirements of the ultra-precise machining have been obtained. The cutting edge radius of the tools is minimized less than 0.05 μm and the radius waviness of the tools is improved no more than 0.2 μm.
