磨具硬度是磨具质量的重要指标之一。喷砂硬度计是当前国内最常用的磨具硬度检查仪器。它虽然是属于静态测量,不能反映出磨具在磨削过程中的动态情况,但是目前它仍然是一种比较理想的测示仪器,它基本上能反映“磨具中磨料与结合剂间的结合强度和磨料与结合剂本身的强度”;经正确的调整后,它具有一定的测量精度和重复性,且能反映出磨具硬度的不均匀性,适用于测定16~#—150~#粒度,直径大于30mm,厚度不小于10mm,硬度为软1～超硬的陶瓷与树脂结合剂砂轮。
Abrasive hardness is an important indicator of abrasive quality. Sandblasting hardness tester is currently the most commonly used abrasive hardness testing equipment. Although it belongs to the static measurement, it can not reflect the dynamic state of the abrasive in the grinding process, but it is still an ideal measuring instrument at present, which basically can reflect “the abrasive in the abrasive and the binding agent Combined with the strength and strength of the abrasive and the binding agent itself ”; after the correct adjustment, it has a certain degree of measurement accuracy and repeatability, and can reflect the unevenness of the abrasive hardness, suitable for the determination of 16 ~ # -150 ~ # Particle size, diameter greater than 30mm, the thickness of not less than 10mm, the hardness of soft 1 ~ super-hard ceramic and resin bond wheel.
