在磨削加工中,钛及钛合金与镍基、铁基合金大不相同。不同牌号、不同加工状态的钛合金,其磨削的难易程度也不同。一、钛的磨削加工特性在磨削钢时,砂轮的孔隙会被金属的磨屑和砂轮破碎下来的微粒全部堵塞,因而磨粒变钝。但是磨削钛时,因为钛的导热率低,局部温差很大,产生的热应力较大。尤其是平面磨削,砂轮与工件的接触面大,热量不易散发,
In the grinding process, titanium and titanium alloy and nickel-based, iron-based alloy is very different. Different grades, different processing state of titanium alloy, the degree of difficulty of grinding is also different. First, the characteristics of titanium grinding Grinding steel, the wheel of the pores will be metal debris and grinding wheel all the particles broken down, and thus abrasive particles dull. However, when grinding titanium, because of the low thermal conductivity of titanium, the local temperature difference is large, resulting in greater thermal stress. In particular, surface grinding, grinding wheel and workpiece contact surface, heat is not easy to distribute,
