五金數控鑽孔機對于機加工來說操作簡便，更加有效率與精度高。數控CNC的自動打孔操作，循環水箱冷切液的冷卻使鑽頭高速運轉的時候，降低鑽頭與工件接觸面熱度與變形。每一個傳動軸均要軸向、經向定位，合理配置主軸的軸承，對于提高主軸部件的精度和剛度、降低支承溫升、簡化支承結構有很大的作用。

五金數控自動鑽孔機要求的精度與效率可以利用滾珠絲杆的摩擦損失小，傳動效率高。在功率消耗只相當于普通絲杆的四分之一，發熱小可實現高速運轉。利用數控鑽孔可對五金部件進行加工，比如：絲杆導軌、五金、金屬零件等。

"And she--ah, yes. I see; and I see, too, that in all she ever said or did or seemed, before, she never made herself such a treasure to be longed for and fought and lived for as in the way in which she--" He paused. But Bruce knew nothing of this change of things. He was utterly puzzled. As he walked home he could make nothing of it. Hetty's story was too circumstantial to be anything but absolutely true. There must have been some strong reason for this change of part. Perhaps Lawrence could throw some light on it. He might even know the man Maitrank. At any rate he was on very friendly terms with Isaac Isidore, who would be sure to have the names of all the European capitalists at his fingers' ends. Lawrence read over the letters carefully, there was less here than he expected. They were all full of vague schemes of making money by various shady ways, and all bewailed the fact that the writer could not obtain the necessary capital to start. Really the letters were hardly worth reading. For loading and unloading carts and waggons, the convenience of the old outside sling is well known; it is also a well-attested fact that accidents rarely happen with sling hoists, although they appear to be less safe than running platforms or lifts. As a general rule, the most dangerous machinery for handling or raising material is that which pretends to dispense with the care and vigilance of attendants, and the safest machinery that which enforces such attention. The condition which leads to danger in hoisting machinery is, that the power employed is opposed to the force of gravity, and as the force of gravity is acting continually, it is always ready to take advantage of the least cessation in the opposing force employed, and thus drag away the weight for which the two forces are contending; as a weight when under the influence of gravity is moved [65] at an accelerated velocity, if gravity becomes the master, the result is generally a serious accident. Lifting may be considered a case wherein the contrivances of man are brought to bear in overcoming or opposing a natural force; the imperfect force of the machinery is liable to accident or interruption, but gravity never fails to act. Acting on every piece of matter in proportion to its weight must be some force opposing and equal to that of gravity; for example, a piece of iron lying on a bench is opposed by the bench and held in resistance to gravity, and to move this piece of iron we have to substitute some opposing force, like that of the hands or lifting mechanism, to overcome gravity. that I have partially discharged that debt--besides, I suppose I could After bathing, during their long prayers to the gods of the river, almost as sacred here as it is at Benares, the pilgrims threw grain to the half-tame fish. Steering vigorously with their tails, the creatures turned and rolled, making eddies of light in the water, and hurrying up to the falling grain occasionally upset the equilibrium of some old woman still taking her bath. At the top of the bank, in the blazing sunshine, two fakirs, squatting in the dusty road, remained unmoved by all this turmoil, seeing nothing, hearing nothing, absorbed in a fixed thought which concentrated their gaze[Pg 297] on an invisible point. The fall of an old woman into the Ganges, with all the shouting that such an incident entails in India, left them quite indifferent; they did not stir, did not even glance at the river as the woman was taken out unconscious. The members all looked up in astonishment. "So I understand," Dr. Haenlingen said. "And you talked. And—whatever his situation—you managed to increase his tension rather than understand or lessen it." "But I d?an't want you to waste your money."
