There are two kinds of common combinations of stone machine linear guide: the first is the combination of double three separation guide. The combination is the combination of open guidance. The maximum dimension α guiding the change of orientation performance of the triangle, the smaller the α, the better the orientation, but the reduced angle α guiding the equivalent friction coefficient, usually limits the greater the triangle railway top angle α to be 90 °. For heavy and large stone machinery, α = 110 ° ~ 120 ° can be taken due to large load. When the triangular guide surface is worn, the worktable will automatically sink to compensate for the wear. The rectangular guide rail has high rigidity, convenient processing and maintenance, but poor orientation. The double triangle guider has high directionality and accuracy retention ability, but it is difficult to process, detect and maintain because of over positioning. Due to the bad working environment of stone machinery, stone powder, water mist and diamond particles are easy to splash on the surface of the guide rail during the cutting process. Because sawing is a kind of heavy cutting, the wear on the surface of the linear guide rail is intensified. At present, some stone mechanical beams are still designed with double triangular guide rails, in order to compensate for the wear of guide rails, the following requirements should be met in the design and processing of linear guide rails.

　　(1)几何精度

　　(1) Geometric accuracy

　　直线运动导轨的几何精度一般包括:导游在垂直平面直线度(以下简称精度),和线性精密直线导轨在水平面(以下简称B项)准确、并行两直线之间的滑动表面也被称为畸变(C)的准确性,在A, B两个精密导轨直线度和指南中规定每米长度的直线度,精度在C语言中,规则在导轨和导轨长度在每米长度,两个导轨表面之间的畸变量在横向每米长度上的值。上述A、B、C的精度公差可参照机床精度检验的相关标准。

　　The geometric accuracy of linear motion guideway generally includes: the guide's straightness in the vertical plane (hereinafter referred to as the accuracy), and the accuracy of linear precision linear guideway in the horizontal plane (hereinafter referred to as item b) and the sliding surface between two parallel lines, which is also called the accuracy of distortion (c). The straightness of two precision guideways A and B and the straightness of each meter length are specified in the guide, and the accuracy is in C language, The rule is that the length of guide rail and guide rail is per meter, and the distortion between the two guide rail surfaces is per meter in the transverse direction. The accuracy tolerance of a, B and C mentioned above can refer to the relevant standards of machine tool accuracy inspection.

　　(2)接触精度

　　(2) Contact accuracy

　　导轨精度精度的精度的接触精度是根据2278-78的规定，用接触面占25×25 (mm)面积的百分比或接触点数来测量的。

　　The contact accuracy of precision of guide rail is measured according to 2278-78 by the percentage of contact surface in 25 × 25 (mm) area or the number of contact points.
