铸铁平板与铸铁平台有区别吗?

铸铁平板又名铸铁平台,是用于工件检测或划线的平面基准量具,是机床、机械制造、电子生产等行业不可缺少的基本装备,其中以重工业使用最为普遍。铸铁平板一般用于各种检验工作,如精密测量用的基准平面,各种机床机械的检验测量,检查零件的尺寸精度、行位偏差,并作出精密划线。在机械制造中铸铁平板也是不可缺少的基本工具。泊头市恒迅机床铸造量具有限公司位于天津以南的泊头市,是生产工具、量具的专业公司。我公司主要生产各种调整、划线平板、防震机床垫铁、千斤顶,也可根据客户需求定制各种型号的机床垫铁。量具系列有平尺、方箱、真角尺、弯板、V型架(铁)、偏摆检查仪和“00”级岩石(大理石)平板、量具量仪等。

铸铁平板设计技术要求一般根据《中华人民共和国机械行业标准》JB/T 7974—2000设计,按国家GB4986-85标准制造平板精度等级有00、0、1、2、3、级及精刨,平板制成筋板式和箱体式,工作面有长方形、正方形或圆形。工作面采用刮削工艺,工作面上可加工V形、T形、U形槽和圆孔、长孔等。

铸铁平板工作面的平面度是指包容平板实际工作面且距离为最小的两平行平面间的距离,其值可按对角线法、环线法的检定结果进行“基面变换”求得。平板工作面的平面度是衡量平板质量的主要精度指标。按平板工作面平面度的公差允许值确定出平板准确级别,因此必须重视平板工作面平面度的检定。平板平面度检定的准确度是平板使用质量的保证。 材料:由高强度铸铁HT200-HT300制造,工作面硬度:HB170-240.


Cast iron plate and cast iron platform, is used to name workpiece inspection or of the following benchmark measuring tools, machine tool is the plane, the manufacturing of machinery and electronic manufacturing industries essential basic equipment, of which the most common use of heavy industry. Cast iron plate are used for various inspection work, such as precise measurement of the plane, with the benchmark all sorts of machine tool of the mechanical measuring and testing, check the size accuracy, the line parts a deviation, and to make the precision crossed. In the mechanical cast iron plate is indispensable in the basic tools. Botou constant newsletter machine tool measuring tools Co., LTD is located in tianjin casting south of botou production tools, measuring tools, is the professional company. I company produces all kinds of adjustment, flat, shock machine crossed mat iron, jack, can also according to customer demand customize various types of machine tools mat iron. Measuring tool series with the leveling ruler, square box, really square rule, curved plates, V type rack (iron), partial put checking and "00" level rock (marble) flat, measuring devices such as quantity.

Cast iron plate design technical requirements general according to the law of the People's Republic of mechanical industry standards "JB/T 7974 2000 design, according to the national GB4986-85 standard manufacture precision grades have flat, 0, 1, 2, 3, level and fine plane, flat steel plate is made and the type, face a rectangle, square or circle. The working process, the work can be on the scraping processing V, T shape, u-shaped slot and round hole, long hole, etc.

The cast iron plate flatness refers to the actual distance and inclusive flat face is the smallest distance between the two parallel plane, the value that can press diagonal method, the verification of the circle line method "the face transform" seek. The flatness is flat plate of the main measure quality precision index. According to the flat face the value of flatness tolerance to determine the exact level, and therefore must be flat plate face on the verification of plane degree. Flat plane degree of accuracy verification is flat use quality guarantee. Material: by the high strength cast iron HT200-HT300 manufacturing, mining face: 240. HB170 hardness
