缸套平顶珩磨是在精加工以后,加入珩磨剂和油,用磨条再进行精加工,将上道工序所留下的毛刺去掉,产生一种细小的网纹,以利贮油和减少初期磨合时间。 平顶珩磨大多是先用金属粘结剂的金刚石磨条(粘结粒度为125/100)进行初珩磨,以形成微观的表面不平度,即贮油槽,然后利用粒度更小的(250/200)金刚石磨条对顶部进行平整。该磨条采用含橡胶的弹性粘结剂P11,这种粘结剂磨条,具有一定限度的弹
Cylinder flat-top honing is finishing after adding honing agent and oil, and then finishing with the grinding process, leaving the burr on the procedure removed, resulting in a fine mesh to facilitate oil storage and reduce Initial run-in time. Flat top honing is mostly performed by initial honing with a metallic binder diamond bead (125/100 bond size) to create a microscopic surface roughness, the sump, and then using a smaller particle size (250/200 ) Diamond bars smooth the top. The mill uses a rubber-containing elastic binder P11, this binder mill, with a limited amount of bombs
