北京cnc機械加工廠之模具抛光

QQ截图20180325085827.jpg

抛光在模具制作加工过程中是很重要的一道工序，也是收尾之作，随着塑料制品的日溢广泛

應用，對塑料制品的外觀品質要求也越來越高，所以塑料模具型腔的表面抛光質量也要

相應提高，特別是鏡面和高光高亮表面的模具對模具表面粗糙度要求更高，因而對抛光

的要求也更高。抛光不僅增加工件的美觀，而且能夠改善材料表面的耐腐蝕性、耐磨性

，還可以方便于後續的注塑加工，如使塑料制品易于脫模，減少生産注塑周期等。

　　目前常用的抛光方法有以下幾種：

　　㈠机械抛光机械抛光是靠切削、材料表面塑性变形去掉被抛光后的凸部而得到平

滑面的抛光方法，一般使用油石條、羊毛輪、砂紙等，以手工操作爲主，特殊零件如回

轉體表面，可使用轉台等輔助工具，表面質量要求高的可采用研抛的方法。

　机械抛光基本程序要想获得高质量的抛光效果，最重要的是要具备有高质量的

油石、砂紙和鑽石研磨膏等抛光工具和輔助品。而抛光程序的選擇取決于前期加工後的

表面狀況，如CNC機械加工、電火花加工，磨加工等等。

"And so here you are in this awful fix." "Those letters--to the newspapers?" "Yes! oh, yes, yes!" His eyes danced, and a soft laugh came, as happy as a child's. "The surgeon is yonder, he will tell you." The man laughed silently, horribly, his body twisting as if set on wires. Then, two and two, carrying on their shoulders heavy trays piled with presents, women mount the steps of the house, the bridegroom standing at the bottom. The bride's mother comes forth to meet them in a dress of pale-coloured China crape covered with a fine white saree. She waves her closed hand three times over the gifts, and then, opening it, throws rice on the ground. This action[Pg 16] she repeats with sugar and sweetmeats, and finally with a coco-nut. And each time she empties her hand a naked boy appears from heaven knows where, gathers up what she flings on the ground, and vanishes again, lost at once in the shadows of the garden. “Have you brought him back?” "Old Manuel he told me. You don't know him. It's an old Greaser, friend of mine. He don't want no one to tell he told, they'd get after him. But it's so, all right. There's three of them." BY the time Shorty had gotten the boys fairly tented, he was ordered to take a squad and guard some stores at the Division Quartermaster's. Si, instead of going on camp-guard, had to go out to the grand guard. When he came back the next morning the Orderly-Sergeant said to him: "What do you mean, good care of him?" she said. But Albin was gone, into the main body of the party, a melee confused enough so that he was lost in twenty steps. Greta turned back almost hopeless eyes. "Of course," the voice said. "We can prepare—as I am doing. There is nothing else for us, not any more. Idealism has taken over, and what we are and what we've done can go right on down the drain. Norma, you're a bright girl—" "But I heard what the doctor said to you." "F?ather's after our land," said Tilly, and shuddered. "My friend," said Manlove; "it matters little now whether you agree with your brethren or not, the woman is at this moment dying! The verdict is, therefore, of little moment to her—she can never be brought into court to receive judgment—guilty or innocent, the law can have nothing to do with her; but I would advise you to look to yourself, you will not be released till she is dead. Your brethren are accustomed to fasting, but you look ready to drop from your seat: and, if the woman linger many hours, you will certainly be guilty of felo de se."
