Cast Iron Table

Cast Iron Table,also known as cast iron flat cast iron platform,is suitable for various inspection work and is a reference plane for measuring degrees.It is mainly used as a reference plane in mechanical workpiece inspection and measurement,to check the dimensional or behavioral deviation of parts,and can be used for marking lines.It is an indispensable flat reference measuring tool in mechanical manufacturing inspection.

The material of the cast iron workbench is high-strength cast iron HT200-300,with a working face hardness of HB170-240.After two manual treatments(manual annealing at 600-700 degrees or natural aging for 2-3 years),the product has stable hardness and good wear resistance.

1、Thickness requirements:mainly including the thickness of the working surface on the platform,the thickness and height of the side panels,as well as the thickness,height,and density of the bottom gluten board.

2、Material requirements:High strength cast iron HT200-300,hardness:HB170-240。

3、Artificial annealing:After high-temperature annealing and aging treatment at 600-700 degrees Celsius in a tempering kiln.

4、Natural aging:According to the national standard,it should take 2-3 years for natural aging.Due to the long process time,it is no longer possible for cast iron platform manufacturers to wait for such a long time due to the impact of capital turnover.Therefore,vibration exciters are often used as a substitute for vibration aging.Although the effect of this process is not yet clear,it has been widely used both domestically and internationally.

5、Trachoma and stomata:Levels 0 and 1 platforms are not allowed to have stomata and trachoma,while levels 2 and 3 can be filled with solid materials of the same material as the platform to fill stomata and trachoma.Attention:The hardness of the filling material must be lower than the hardness of the platform itself.

6、Scraping process:Manual scraping is an important process in the processing of cast iron platforms,which determines the flatness error of the cast iron platform and the number of touchable points on the working surface.The 0-level board platform shall have no less than 25 points within a range of 25mm square on each side;The first level platform shall have no less than 20 points within a range of 25mm square on each side;The second level tablet platform shall have no less than 16 points within a range of 25mm square on each side;The 3-level tablet platform shall have no less than 12 points within a range of 25mm square on each side.After the scraping is completed,the four edges of the platform become dull.

7、Cleaning and painting:The bottom surface of the platform should be cleaned and sprayed with red anti rust paint.The side should be leveled before painting,usually with basket paint or green paint.

8、Packaging requirements:Mainly wooden packaging,try to use thick wood to cover the working surface on the platform,and sometimes do fully enclosed packaging.Rust prevention measures must be taken for the working surface of the platform before packaging.9、Transportation requirements:After loading on the platform,check if there is any suspension.If there is any suspension,it should be padded to avoid vibration.Do not stack the platform too high to avoid deformation due to compression.

10、Accessory selection:The main focus is on the selection of brackets,which are made of square steel and angle iron with a wall thickness of 1.5-2mm.The welding density and structure should be reasonable,and the adjusting bolts should rotate smoothly.

11、Installation and debugging:Generally,a frame level is used to level it first,and then an optical or electronic image level is used to measure the flatness error again.If there are any problems,the cast iron platform manufacturer can be requested to scrape and restore the flatness on site.

12、Correct use:The cast iron platform can be used after debugging is completed.The room temperature should be controlled at 20±5℃.When testing workpieces on the table,they should be placed and moved gently.Do not concentrate on using one area,and try to use the entire cast iron platform evenly.

Cast iron workbench degree:

According to the standard metrological verification regulations,there are six levels:00,0,1,2,3,and planer.
