1 大工件金相制样用抛光头将抛光织物裁成12mm宽的条带,将条带的一端嵌入图1中φ4端的1mm的缝隙内,φ4端朝上,类似于做圆黑板擦织物条带紧紧的缠绕在φ4小柱上,当缠绕的直径接近φ40时,将外圆用橡皮套固定,这样一个抛光头即制成。将抛光头用水浸润后涂上金刚石研磨膏卡在手电钻上即可进行抛光。此抛光头可长期使用,脏了用板刷刷洗即可。 1 large workpiece metallographic sample with a polishing head will be polished fabric cut 12mm wide strip, one end of the strip embedded in FIG. 1 φ4 end of the 1mm gap, φ4 end up, similar to the round blackboard to do the fabric strip With tight winding φ4 small column, when the diameter of the winding close to φ40, the outer ring with a rubber sleeve fixed, such a polishing head that is made. The polishing head with water immersion coated with diamond polishing paste stuck in the flashlight can be polished. This polishing head can be long-term use, dirty with a brush can be scrubbed.
