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)幾何精度

　　(1) Geometric accuracy

　　直線運(yùn)動導(dǎo)軌的幾何精度一般包括:導(dǎo)游在垂直平面直線度(以下簡稱精度),和線性精密直線導(dǎo)軌在水平面(以下簡稱B項)準(zhǔn)確、并行兩直線之間的滑動表面也被稱為畸變(C)的準(zhǔn)確性,在A, B兩個精密導(dǎo)軌直線度和指南中規(guī)定每米長度的直線度,精度在C語言中,規(guī)則在導(dǎo)軌和導(dǎo)軌長度在每米長度,兩個導(dǎo)軌表面之間的畸變量在橫向每米長度上的值。上述A、B、C的精度公差可參照機(jī)床精度檢驗的相關(guān)標(biāo)準(zhǔn)。

　　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)接觸精度

　　(2) Contact accuracy

　　導(dǎo)軌精度精度的精度的接觸精度是根據(jù)JB2278-78的規(guī)定，用接觸面占25×25 (mm)面積的百分比或接觸點(diǎn)數(shù)來測量的。

　　The contact accuracy of precision of guide rail is measured according to jb2278-78 by the percentage of contact surface in 25 × 25 (mm) area or the number of contact points.
