一般平面研工件磨方法

发布时间：2019/1/14 23:21:00 来源：河北興創機械制造有限公司

一般平面的研磨是在平整的研磨平板上進行的。研磨平板分有槽和光滑的兩種。粗研磨時，在有槽研磨平板上進行。因爲有槽研磨平板能_工件在研磨時整個平面內有足夠的研磨劑並保持均勻，避免使表面磨成凸弧面。精研時，則應在光滑研磨平板上進行。研磨平板,平面研磨

一般平面的研磨是在平整的研磨平板上進行的。研磨平板分有槽和光滑的兩種。粗研磨時，在有槽研磨平板上進行。因爲有槽研磨平板能_工件在研磨時整個平面內有足夠的研磨劑並保持均勻，避免使表面磨成凸弧面。精研時，則應在光滑研磨平板上進行。

研磨前，先用煤油或汽油把研磨平板的工作表面清洗幹淨並擦幹，再在研磨平板上涂上适当的研磨剂，然后把工件需要研磨的表面（已去除毛刺并清洗过）合在研磨平板上。沿研磨平板的全部表面，以8字形或螺旋形的旋轉與直線運動相結合的方式進行研磨，並不斷變更工件的運動方向。由于周期性的運動，使磨料不斷在新的方向起作用，工件_能較快達到所需要的精度要求。

研磨時，要控制好研磨的壓力和速度。對較小的高硬度工件或粗研時，可用較大的壓力和較低的速度進行研磨。有時爲減小研磨時的摩擦阻力，對自重大或接觸面較大的工件，研磨時，可在研磨劑中加入一些潤滑油或硬脂酸起潤滑作用。

在研磨过程中，应防止工件发热，若稍有发热，应立即暂停研磨，避免工件因发热而产生变形。同时，工件在发热时所测尺寸也不准确。

In the first place, the corner house was already marked as the scene of one unsolved tragedy. For years it had been shut up, for years the boys of the locality had challenged one another to go down the area steps after dark, for years nobody had crossed the threshold. Then the door had been left open for the public eye to look on another tragedy. In a café, lower down, near the canal I saw a number of German soldiers, and was successful in having a chat with the inn-keeper, at the farthest corner of the bar. I asked him, of course, what they meant by burning the village, and he told me that the Germans had made a number of unsuccessful attacks on Fort Pontisse, until at last they reduced it to silence. They were now so near that they could open the final assault. They were afraid, however, of some ambush, or underground mine, and the Friday before they had collected the population, whom they forced to march in front of them. When they had got quite near they dared not enter it yet, and drove the priest and twelve of the principal villagers before them. That is how Pontisse was conquered. CHAPTER X "'6. I am convinced that on the whole the treatment of the wounded was generous and exemplary. But it is also a fact that the terrible hatred of the Germans against the British, encouraged by their military authorities (one has to think of the proclamation of Prince Rupert of Bavaria) and their scandalous comic papers, which disgust even decent Germans, induce to extravagances such as I witnessed at Landen. Did not a German officer explain to an editor of the Algemeen Handelsolad (evening issue of October 18th): "The unwritten order is to make everywhere as many French and as few English prisoners as possible; we don't try to wound, but to kill the British."'" A survey of the Socratic philosophy would be incomplete without some comment on an element in the life of Socrates, which at first sight seems to lie altogether outside philosophy. There is no fact in his history more certain than that he believed himself to be constantly accompanied by a Daemonium, a divine voice often restraining him, even in trifling matters, but never prompting to positive action. That it was neither conscience in our sense of the word, nor a supposed familiar spirit, is now generally admitted. Even those who believe in the supernatural origin and authority of our moral feelings do not credit them with a power of divining the accidentally good or evil consequences which may attend on our most trivial and indifferent actions; while, on the other hand, those feelings have a positive no less than a negative161 function, which is exhibited whenever the performance of good deeds becomes a duty. That the Daemonium was not a personal attendant is proved by the invariable use of an indefinite neuter adjective to designate it. How the phenomenon itself should be explained is a question for professional pathologists. We have here to account for the interpretation put upon it by Socrates, and this, in our judgment, follows quite naturally from his characteristic mode of thought. That the gods should signify their pleasure by visible signs and public oracles was an experience familiar to every Greek. Socrates, conceiving God as a mind diffused through the whole universe, would look for traces of the Divine presence in his own mind, and would readily interpret any inward suggestion, not otherwise to be accounted for, as a manifestation of this all-pervading power. Why it should invariably appear under the form of a restraint is less obvious. The only explanation seems to be that, as a matter of fact, such mysterious feelings, whether the product of unconscious experience or not, do habitually operate as deterrents rather than as incentives. did I, that Amasai and Carrie got married last May? They are still He came at length, a little dapper man, with a slight hump between the shoulders, a nose slightly crooked on one side. He appeared to take his warm welcome quite as a matter of course, he discarded a pair of grey suède gloves, and called for a bottle of champagne. The fog was thinning under them, blowing aside, swirling, shifting. That supported his decision that neither a single robber nor a band of miscreants had planned the affair. They would have taken all the real stones, and he believed that these were numerous. "I put them in this here book," he said, "betwixt the leaves, and then I put the book under my saddle and set on it. I don't weigh so much, but it works all right," he added, looking up with a na?ve smile that reached from one big ear to the other. "To-morrow," he told him later, "I'm going to ride over here to Tucson again. What way might you be takin'?" The one man at bay whirled round twice, with a bullet in his heart and an arrow through his neck. "Now!" he made one fierce effort to cry, as he staggered again and dropped on his face, to be trampled under forty feet. Cope maintained the order of battle arranged the day previous, except that he turned the men's faces towards the east instead of the west, to meet the new position of the enemy. His infantry was posted in the centre; Hamilton's dragoons were on the left, and Gardiner's with the artillery in front, on the right, leaning on the morass. The Highlanders no sooner saw the enemy than, taking off their caps, they uttered a short prayer, and pulling their bonnets over their brows, they rushed forward in their separate clans with a yell that was frightful. "What are you foolin' with the ole hayseed for?" said another teamster, coming up behind Groundhog. "Slap the old hawbuck over, snatch up the kittle and run with it. I'll do it if you don't." And human nature, he knew with terror, was about to be overthrown once more. "Don't come any further." HoME 朴妮唛各部ENTER NUMBET 0019cy-edu.com.cn
