随着对机床高速、高加速度和稳定驱动的需求不断增长，
直线电机在机床中的应用越来越多。另一方面，为了实现高质量，工业产品对镜面光洁度表面的需求也大大增加。本研究探讨使用线性马达开发高速精细抛光工艺，在小零件上实现镜面抛光表面。该过程的第一阶段包括开发抛光装置，该抛光装置由数控铣床、线性电机驱动器和抛光头组成。具体地，将连接到线性电机驱动器的抛光头与NC铣床的主轴耦合。一个小的线性电机驱动器的替代品是从市售剃须刀，而抛光头制成
丙烯。对抛光头的加工工艺、直线电机的驱动性能、研磨剂及

所提出的系统能够实现镜面状的精加工表面，（2）当与用超声波马达抛光相比时，所提出的系统的加工时间减少一半，（3）所提出的系统能够在3mm正方形的侧面区域上实现镜面状的精加工。
As high speed, high acceleration and stable drive on machine tools is constantly growing in demand, the use
of linear motors in machine tools has increased. On the other hand, in order to achieve a high degree of quality, the need for mirror-like finish surfaces on industrial products has also considerably increased. This research explores the use of linear motors to develop a high-speed fine polishing process that achieves a mirror-like finish surface on small parts. The first stage of this process consisted in developing a polishing device, which was composed of a NC milling machine, a linear motor drive and a polishing head. Specifically, a polishing head attached to a linear motor drive was coupled with the spindle of a NC milling machine. A substitute for a small linear motor drive was obtained from a commercially available shaver, while the polishing head was made
of propylene. The polishing head elaboration process, linear motor drive properties, lapping agent and
the optimum polishing conditions were investigated in several experiments. The evaluation consisted in the high-speed polishing of minute areas on flat surfaces using the selected optimum conditions. It is concluded that, (1)
the proposed system was able to achieve a mirror-like finish surface, (2) when compared to polishing with an ultrasonic motor, the machining time of the proposed system was reduced by half, (3) the proposed system was able to achieve a mirror-like finish on a 3 mm square sided area.
