装配平台HT200-300

检验平台

5 N( D+ q9 ^/ j( ]装配平台用途：应用于动力机械设备的装配及调试，表面带有T形槽，装配平台可以固定动力机械设备。工作面上可加工圆孔、U型孔或长孔。材质：优质高强度灰口铸铁HT200-250，工作面硬度为HB170-240，铸件经过两次人工退火600℃-700℃或自然时效2-3年，完全去除内应力，精度稳定，耐磨性能好。
, ]4 P4 N$ F: g装配平台包装：木制包装。包装前经防锈处理并妥善包装，避免因包装不善而在运输过程中损坏产品。平板经检定合格后，应附有产品合格证;产品合格证上应出厂日期和产品序号。
3 Z8 y" i6 p. Q' q0 i$ a装配平台是划线、测量、铆焊、工装工艺不可以缺少的工作台，也可以做机械试验平台等等。在装配平台的生产设计上采用箱体式、筋板式或其他结构型式。在装配平台的相对两侧面上，应有安装手柄或吊装位置的设置、螺纹孔或圆柱孔。
装配平台技术要求  1、平板工作面不得有严重影响外观和使用性能的砂孔、气孔、裂纹、夹渣、缩松、划痕、碰伤、锈点等缺陷。
2、平板的铸造表面应清除型砂且平整，涂漆牢固。

5、平面度公差见表2的规定。
Assembly plate are usually used to fit and debug the equipment.there are T-slot on the surface plate to fit the workpiece. Additionally, we can machine the round hole U-shaped, slot holes or other your desire on the surface plate.
5 R$ D9 f  k% b' ^! T9 u3 ^) jThe raw material of the cast iron assembly plate is the high -strength cast iron HT200-300 ，whose surface hardness is of HB170-240.After the two manual handing such as 600℃ to 700℃ artificial annealing as well as 2 to 3 years of natural aging, the T-slot has plate perfectly resists abrasion and has stable precision.
