电磁吸盘平面磨削方法对比

发布时间:2018-03-11 16:24编辑:河北悍将电磁吸盘厂家浏览次数:

        电磁吸盘根据需要调整进给 磨削平面速度,磨削可停机,以较精确检查尺寸。
    平面磨削方法有两种,一种端磨法,用砂轮端面进行磨削,因其接触面大,易发热,且冷却液难以浇到工件易发热变形,因而磨削精度较低,但生产率较高。另一种周磨法。刚好端磨法相反,它磨削效率较低,但加工精度较高。 电磁吸盘有的时候也采用粘结磁体的方式,这其中有利有弊,利大于弊,采用这种方式的优点是什么呢? 
   1)形状自由度大 容易制成形状复杂的磁体或薄壁环、薄片状磁体。注射成形时还能嵌入其他零件一起成形。
  2)电磁吸盘尺寸精度高,不变形烧结磁体的收缩率为13%~27%,而粘结磁体的收缩率只有0.2%~0.5%。不需要二次加工就能制成高精度的磁体。
    Grinding plane, generally with a plane as the positioning datum, grinding another plane, if the two planes are required to grinding, can be the basis of repeated grinding. According to the need to adjust the feed speed, grinding can be stopped, to check the size of the more accurate.There are two kinds of plane grinding method, an end grinding method, grinding wheel surface, because of its large contact surface, easy to heat, and the cooling liquid to pour into the workpiece heat deformation, thus grinding accuracy is low, but higher productivity. Another grinding method. On the contrary, the grinding efficiency is low, but the machining precision is high. Sometimes the magnechuck bonded magnets, the advantages outweigh the disadvantages, the There are both advantages and disadvantages., what are the advantages of this approach?1 the degree of freedom of the shape is easy to be made into a magnet with a complex shape or a thin wall ring and a thin sheet magnet. Injection molding can also be embedded with other parts forming.27%. The high precision of the electromagnetic chuck, the shrinkage rate of the sintered magnet is 13% ~ ~ ~ (2), and the shrinkage rate of the bonded magnet is only about 0.2% ~ 0.5%. High precision magnets can be made without two machining.
