Fine-grinding parameter determinator and application thereof

The invention relates to a fine-grinding parameter determinator. The determinator adopts a speed adjustable motor, a sand wheel, a test sample, a loading lever with an adjustable cutter feeding amount and a water cooling system to form a device. By adopting the determinator, parameters such as grinding speeds, surface coarseness, precision and the like of different types of grinding sand wheels (metal-based combined diamond sand wheels, glass-based combined diamond sand wheels and the like) for Si3N4 materials, various ceramic materials or various ultra-hard alloys at different grinding speeds and under different grinding pressure can be rapidly determined in a short time. Meanwhile, the friction abrasion parameter of the surface of silicon nitride materials and other materials when in pairing friction movement can be determined. 本发明涉及种精磨加工参数测定仪。测定仪是利用可调速电机、砂轮、试样、带有可调进刀量的加载杠杆以及水冷系统组成的种设备。该测定仪可在短时间内快速测量出不同种类的研磨砂轮（金属基结合的金刚石砂轮、玻璃基结合的金刚石砂轮等）在不同的研磨速度，不同的研磨压力下对SiN材料及各种陶瓷材料或各种超硬合金的磨削速度、表面粗糙度及精度等参数。同时可以测定氮化硅材料与其他材料表面
