划线平台
是检验机械零件平面、平行度、直线度等形位公差的测量基准，也可用于一般零件及精密零件的划线、铆焊研磨工艺加工及测量等，是测量中不可缺少的必备工具。The face plate is the examination machine parts plane, the parallelism, the straight line equiform position common difference measuring basis, may also use in the general components and the precise components lineation, the rivet welding attrition craft processing and the survey and so on, is in the survey the essential necessary tool. 精固诚量具公司位于铸造名城河北泊头，东临京沪铁路、104国道，西临106国道，交通运输极为便利，地理位置优越，公司主要产品、研磨平板、研磨平台、、T形槽平板、检验平台、划线平板、划线平台、铆焊平板、铆焊平台、、焊接平板、焊接平台、T形槽平台、方箱、磁性方箱、Ｖ型铁、磁性Ｖ型铁、Ｖ型架、平尺、桥型平尺、直角尺、方尺、机床专用角度尺、弯板、阶梯垫铁、等高垫铁、偏摆检查仪、齿轮跳动仪花岗石平尺、花岗石方尺、花岗石方箱、机床检验棒、机床可调垫铁、机床防震垫铁、特种扳手等；花岗石类：花岗石平台、花岗石Ｖ型块等。
划线平台按JB/T7974-1999标准制造,产品制成筋板式和箱体式,工作面有长方形、正方形或圆形。划线平台工作面的精度可以保持使用2年以上，精度降低时可以通过调试或刮研工艺恢复，划线平台本身的使用寿命可以达到50-100年，在使用划线平台的过程中要注意不要在潮湿，有腐蚀、温度环境过高和过低时使用，否则影响划线平台的使用寿命。测量时为了防止划线平台发生变形，要将支承支在主支点处。支承时，尽量将划线平台的工作面调整到水平面内。检验完毕或划线完毕后，要把工件卸下来，不得长时间放在平板上。使用完毕，要及时清理划线平板的工作面，然后涂上一层防锈油。如果比较长时间不用，{zh0}涂上一层黄油，然后铺一层白纸防止灰尘污染。严禁水滴在平板上,做到定期检查。The face plate according to the JB/T7974-1999 standard manufacture, the product makes the muscle beat and the box writing style, the working surface has the rectangle, the square or the circular. The face plate working surface's precision may maintain uses above 2 years, the precision reduces when may or blows through the debugging grinds the craft to restore, face plate's service life may amount to for 50-100 years, must pay attention in the use face plate's process do not in moist, has the corrosion, temperature environment Gao He is low when to use, otherwise influence face plate service life. When survey to prevent the face plate to have the distortion, must supporting in the main pivot place. When supporting, as far as possible face plate's working surface will adjust in the horizontal plane. After the examination finished or the lineation finished, must the work piece unload down, do not the long time place on the plate. The use finished, must clean up the streak plate promptly the working surface, then spread pickling oil. If the quite long time does not use, best spreads butter, then spreads a white paper to prevent the dust pollution. Refuses the waterdrop on the plate, achieves the periodic inspection.
划线平台材质HT200-300。使用环境温度（20±5）℃。
