　　石材機(jī)械直線導(dǎo)軌常見的兩種組合:種是雙三分離導(dǎo)軌組合。組合都是開放的指導(dǎo)相結(jié)合,指導(dǎo)三角形的取向性能變化的尺寸α,α越小解取向,越好,但減少的角度α指導(dǎo)等效摩擦系數(shù),通常限制三角形鐵路頂角α越大是90°,重型、大型石材機(jī)械,由于大負(fù)荷,可取的α= 110°~ 120°。當(dāng)三角導(dǎo)軌面磨損時(shí)，工作臺(tái)會(huì)自動(dòng)下沉以補(bǔ)償磨損量。矩形導(dǎo)軌鋼度高，加工、檢修方便，但定向差。雙三角導(dǎo)向器具有較高的方向性和精度保持能力，但由于過度定位，使加工、檢測(cè)和維護(hù)困難。由于石材機(jī)械惡劣的工作環(huán)境，在切割過程中容易有石粉、水霧和金剛石顆粒飛濺在導(dǎo)軌表面。由于鋸切是一種重型切削，直線導(dǎo)軌表面的磨損加劇。目前部分石材機(jī)械梁仍采用雙三角導(dǎo)軌設(shè)計(jì)，目的是為了補(bǔ)償導(dǎo)軌的磨損，在設(shè)計(jì)加工直線導(dǎo)軌時(shí)應(yīng)滿足以下要求。

　　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.

　　直線運(yùn)動(dòng)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(jiǎn)稱精度),和線性精密直線導(dǎo)軌在水平面(以下簡(jiǎn)稱B項(xiàng))準(zhǔn)確、并行兩直線之間的滑動(dòng)表面也被稱為畸變(C)的準(zhǔn)確性,在A, B兩個(gè)精密導(dǎo)軌直線度和指南中規(guī)定每米長(zhǎng)度的直線度,精度在C語(yǔ)言中,規(guī)則在導(dǎo)軌和導(dǎo)軌長(zhǎng)度在每米長(zhǎng)度,兩個(gè)導(dǎo)軌表面之間的畸變量在橫向每米長(zhǎng)度上的值。上述A、B、C的精度公差可參照機(jī)床精度檢驗(yàn)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) 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(cè)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.
