泊头北重直销铸铁工作台,T型槽铸铁工作台:铸铁工作台适用于各种检验工作,精度测量用的基准工作台. 铸铁工作台也用于机械工件检验测量中的基准面,检查零件的尺寸精度或行为偏差,并可作精密划线,在机械制造检验中是最不可缺少的平面基准量具。
铸铁工作台 材质为高强度铸铁HT200-300,工作面硬度为HB170-240,经过两次人工处理(人工退火600度-700度或自然时效2-3年)因此该产品的精度稳定,耐磨性能好。
精度:按国家标准计量检定规程执行,分别为00、0、1、2、3和精刨六个等级
铸铁工作台的使用:铸铁工作台在使用磨损后,可以重新修刮恢复其精度。
铸铁工作台可用涂色法检验零件平面度,具有准确、直观、方便的优点。在经过刮研的铸铁工作台上推动表座、工件比较顺畅,无发涩感觉,方便了测量,保证了测量准确度。
铸铁平板的铸铁质量和热处理质量对平板使用性能产生较大影响:或因残存较大内应力使工作面变形;或因不耐磨损使精度不能保持;或因刮削困难得不到数值小的粗
糙度。因此使用铸铁工作台必须注意铸铁材料的选择,采用时效处理等方法**铸铁平板的残余应力。
The cast iron surface plate
serves as the measuring basis, which is used for inspecting the machinery
parts`geometric tolerance such as flatness ,straightness ,etc.Also, it can be
used to the scribbling , abrasive machining equipment installation and more.
The raw material of the cast
iron surface table is the high -strength cast iron HT200-300 ,whose surface hardness is of HB170-240.After the two manual handing
such as600℃to700℃artificial annealing as well as 2 to 3
years of natural aging, the T-slot has plate perfectly resists abrasion and has
stable precision.
Precision accuracy:surface
plates shall be classified as Grade 00,Grade0, Grade 1.Grade 2.Grade3 ,and
finish polishing.
We can use the coloring
method to insepct the flatness ,which is accurate , direct ans convenient. |
