The present invention relates to a grinding device cutting the surface of a process object, specifically, with the aim of a smooth and precise movement of a transfer grip portion by minimizing friction between the transfer grip portion and a guide rail while the transfer grip portion moves on the guide rail of a table. In addition, the present invention can prevent an increase of production costs by embodying a friction reduction phenomenon between the transfer grip portion and the guide rail through a very simple structure. Moreover, the present invention enables the transfer grip portion to be more stable and precise by preventing foreign materials such as dust and the like which are stacked on the guide rail from being introduced into a gap between the transfer grip portion and the guide rail during the grinding process. |
