华北地区T型槽平台**新价格
T型槽平台用途：主要用来固定工件，是钳工工人用来调试设备，装配设备，维修设备的基础工作平台。 T型槽平台的生产过程为 ：做型&**sh;铸造&**sh;机床加工&**sh;刮研&**sh;检验&**sh;包装&**sh;发货或入库。 平台在生产的过程中需要经过两次回火处理，然后上机床加工，**后人工刮研。经过两次回火后平台的精度更加稳定，**性能更好，人工刮研可以使铸铁T型槽平台达到理想的精度。
T型槽平台T型槽平台 材质：**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，**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、锈点等缺陷。
②T型槽平台的表面应清除型砂且平整，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**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**大允许值为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 wo**ng surface, when inspected visually, shall be free from blowholes, sand holes, cracks, slag inclusions scratches, porous patches and other visual flaws.
2.The wo**ng surface shall be clean and uniform and the other sides shall be painted well.
3,the plugging of blowholes or porous patches in the wo**ng surface whose accuracy is Grade 0- Grade 3 with material of a similar **position 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-grai** 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.
