T型槽平台价格，加工T型槽平台，T型槽工作台型号北重机械供应。
T型槽平台T型槽平台
材质：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度和自然时效2-3年）使用该产品
的精度稳定，耐磨性能好。
T型槽平台精度：按国家标准计量检定规程执行，分别为0、1、2、3四个等级。
技术要求①T型槽平台工作面不得有严重影响外观和使用的砂孔、气孔、裂纹、缩松、划痕、碰伤、锈点等
②T型槽平台的表面应**型砂且平整，涂漆牢固。
③精度等级为0级-3级的T型槽平台工作面上，直径小于15mm的砂孔允许用相同材料堵塞，其硬度应小于周围材料的硬度。工作面堵塞的砂孔应不多于4个，且砂孔之间的间距应不小于80mm。
④T型槽平台应采用优质细密的灰口铸铁或合金等材料制造，其工作面硬度应达到170-220HB。
⑤T型槽平台工作面通常应采用刮削工艺。对采用刮削加工的3级T型槽平台工作面，其表面粗糙度Ra的**允许值为5um。
⑥采用刮削工艺应进行涂色对研检验。对研后显示的接触点面积的比率见表3的规定：或者按25mm×25mm正方形面积的接触点数见表3的规定，且任意25mm×25mm中的接触点数之间应不大于5点。
T-slot plate are mainly used
as fitting workpieces. Which is the fadation plate of adjustng, assembling and
reparing equipments.
The raw material of the cast
iron T-slot 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:T-slot plates shall be
classified as Grade 0, Grade 1, Grade 2, and Grade 3.
Technical requirements of
T-slot Plate:
1.The working surface, when
inspected visually, shall be free from blowholes, sand holes, cracks, slag
inclusions scratches, porous patches and other visual flaws.
2.The working surface shall
be clean and uniform and the other sides shall be painted well.
3,the plugging of blowholes
or porous patches in the working surface whose accuracy is Grade 0- Grade 3
with material of a similar composition is permitted provided that such a repair
does not affect stability or accuracy.
4,The raw material of Cast
Iron Surface Plate shall be the close-grained cast iron whose hardness is of HB
170~220.
5, the surface plate are
usually adopted the scraping technology.
6, the surface plate after
scraping technology need coloring method for inspection. |
