检测平台外形：按JB/T7974-1999标准制造，产品制成筋板式和箱体式，检测平台工作面有长方形、正方形或圆形。检测平台(平板)材料：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°--700°和自然时效2--3年）使该产品的精度稳定，耐磨性能好。检测平台(平板)用途：适用于各种检验、检测工作，精度测量用的基准平面用于机床机械检验测量基准，检查，并作精密零件的尺寸精度或行为偏差，并作精密划线，在机械制造中也是不可缺少的基本工具。
Cast Iron Inspection Plate
Cast Iron Inspection Plate
can be made into rib type and box type and the working surface are typically
square, rectangular or round and are allowed to machined V, T or U-shaped
grooves and round holes or other holes.
Material:
The material of Cast Iron
Testing Plate is high-strength cast iron HT200 and HT250. After two times’
artificial heat aging treatment( Artificial annealing temperature600℃to700℃or 2-3 years natural aging) the internal stress
was totally eliminated, so the surface plate have stable accuracy and good
wear-resisting performance.
Usage:
Cast Iron Testing Surface
Plate is always used as the datum for measurement of the machinery parts’
geometric tolerance,such as flatness, parallelism, straightness and more. It is
also can be used for precision inspection, marking out (layout), and tooling
setup. It is an indispensable basic equipment in most mechanical
manufacturing industries. |
