Scraping research platform

Scraping and grinding platform,also known as scraping and grinding flat plate,is a flat reference tool used for workpiece detection or marking,mainly used as a benchmark for checking workpiece errors.The scraping and grinding platform is manufactured according to the GB/4986-85 standard,and the working surface is polished using a grinding process.It is used for grinding parts and repairing measuring tools.

Scraping research platforms are widely used in industries such as mechanical manufacturing,chemical engineering,hardware,aerospace,petroleum,automotive manufacturing,and instrument manufacturing.

Surface quality inspection of scraping and grinding platform:using color coating for inspection,there should be no less than 25 points for level 0 flat plates within a range of 25 millimeters per square meter,no less than 20 points for level 1,no less than 16 points for level 2,and no less than 12 points for level 3.

Technical requirements for scraping and grinding platform:

1.The working surface of the scraping and grinding platform shall not have defects such as sand holes,pores,cracks,slag inclusions,shrinkage,scratches,bumps,rust spots,etc.that seriously affect the appearance and performance.

2.The casting surface of the scraping and grinding platform should be sand shaped and flat,and the paint should be firm.

3.On a flat working surface with accuracy registered as level 0-3,sand holes with a diameter less than 15mm are allowed to be blocked with the same material,and their hardness should be less than that of the surrounding materials.There should be no more than 4 sand holes blocked in the working face,and the spacing between the sand holes should not be less than 80mm.

4.The scraping and grinding platform should be made of fine gray cast iron or alloy materials,and its working surface hardness should be 170-220HB.

5.Scraping technology should usually be used on the working surface of the scraping and grinding platform.The maximum allowable value of surface roughness Ra for a level 3 flat working surface processed by scraping is 5um.

6.The working surface of the scraping and grinding platform should undergo color matching inspection when using scraping technology.

Instructions for using the scraping and grinding platform:

1.Before use,use non corrosive gasoline,wash the working surface with rust proof oil,and wipe it clean with degreased cotton yarn before use.

2.Temperature changes can cause measurement errors and should be used within the range of 20±5℃.

3.Use a spirit level to adjust to the horizontal position,so that the fulcrums are evenly distributed on each fulcrum.

4.Be careful and avoid collisions when using.

5.After use,wipe clean,apply anhydrous and acidic rust proof oil,cover with paper,and store in a clean and dry place.

6.Weekly inspection period:The long weekly inspection period is one year.
