如何很好的利用固著磨料“高速，高效”這樣一種研磨特點?固著磨料研磨這種的加工方式主要被運用在對于納米級的零部件的研磨加工過程中。固著磨料的高速研磨與傳統(tǒng)的散粒磨料研磨所不相同的是，固著磨料的高速研磨的磨料密度分布是可以認(rèn)為控制調(diào)節(jié)的。
可以根據(jù)不同零部件的在磨具間的相對運動情況的密度分布，合理地設(shè)計機使用在磨具上磨料密度分布，這樣可以使得磨具在加工的過程中，所形成的一定磨損，對于磨具的形態(tài)精細(xì)程度沒有造成很大的影響，從而大大增加了工件的形態(tài)精細(xì)程度，并且避免了重新修理調(diào)整磨具的麻煩。這樣不僅可以起到降低成本的作用，而且還對產(chǎn)品質(zhì)量有了巨大的提升，提高了產(chǎn)品在行業(yè)中的競爭力，也給企業(yè)帶來了客觀的收益。在同一平面中，使用固著磨料研磨的過程中，以磨具的旋轉(zhuǎn)運動為主，而零部件的運動為輔。在大多數(shù)情況下，工件是以浮動的形式放置在磨具上，它的運動的形式是沒有規(guī)律可言的。所以，要對工件的受力情況進行進一步的分析，這樣才能尋找出它的受力狀態(tài)及運動規(guī)律。
為了保障研磨機的運轉(zhuǎn)的穩(wěn)定性及平穩(wěn)性，主機使用的驅(qū)動為調(diào)速電機驅(qū)動系統(tǒng)，并配備有大功率的減速系統(tǒng)和軟啟動、軟停止系統(tǒng)。在加工的過程中，通過上、下研磨盤，太陽輪與游星輪所組成的組件，形成四個方向、速度相互協(xié)作的研磨運動，這樣就可以達(dá)到組件與組件間，相互合作協(xié)調(diào)，使研磨運作更為高速，提高研磨的效率。下研磨盤可以升高，也可以降低，這樣的設(shè)計可以方便于工件安裝與拆卸。在研磨機上，氣動太陽輪變向這一裝置的安裝，可以使工件的不同平面的研磨精細(xì)程度和研磨的速率得到更為精準(zhǔn)正確的控制。

How good is the use of fixed abrasive" high-speed, high efficiency " of such an abrasive characteristics? Solid abrasive lapping the advanced processing method is mainly used in the nanoscale parts of grinding process. Fixed abrasive high speed grinding and traditional loose abrasive grinding are not the same, solid abrasives high-speed grinding abrasive density distribution can be thought to control regulation.
According to different parts in grinding of relative motion between the density distribution, the rational design of machine used in abrasive abrasive density distribution, this makes the grinding tools in machining process, the formation of a certain abrasion, abrasive form for fine degree did not cause a great impact, thus greatly increasing the workpiece to form fine degree, and to avoid the trouble adjusting tool repair. It can not only play the role of reducing cost, but also on the quality of products has a great promotion, improve product competitiveness in the industry, also bring objective income. In the same plane, using a fixed abrasive lapping process, the abrasive rotary motion, and parts of the movement as a supplement. In most cases, the workpiece is placed in the form of a floating abrasives, its motion form there is no law at all. Therefore, the workpiece force for further analysis, so as to find out its stress state and law of motion.
In order to ensure the grinding machine operation stability and smoothness, host using the drive for variable speed motor driving system, and equipped with high-power reduction system and soft starting, soft stop system. In the process, through the upper, the lower grinding disc, a sun wheel and planetary wheel is composed of components, to form a four direction, speed collaborative grinding motion, which can achieve assembly and components, mutual cooperation and coordination, so that the grinding operation for high speed, improve the grinding efficiency. The lower grinding disc can be raised, can also be reduced, so that the design can be convenient for mounting and dismounting the workpiece. In a grinding machine, pneumatic sun wheel turns to the installation, the workpiece can be of different planar grinding fineness and the grinding rate more accurately correct control.
