T-slot platform

Cast iron T-groove platform,also known as T-groove flat plate,is a type of cast iron flat plate with a T-groove on the surface,used as a measuring tool for assembling and debugging mechanical equipment.The cast iron T-groove platform,like the marking platform,strictly adheres to relevant industry standards.Using cast iron casting,not only is the accuracy stable,but also.

The cast iron T-groove platform is used as a benchmark for the assembly,debugging,welding,and riveting of power machinery equipment.Mechanical equipment can be fixed.The specifications can be manufactured according to user needs.

Precision of cast iron T-groove platform:According to the standard metrological verification regulation JJG117-91,it is classified as level 3 and precision planing.

Surface treatment of cast iron T-shaped groove platform:The working surface adopts scraping and grinding technology,and is inspected by color coating method to improve the flatness accuracy.The working surface generally has T-shaped grooves,and can also be processed with long or circular holes according to requirements.

Technical requirements for cast iron T-groove platform:

1.The use of scraping technology should undergo color comparison inspection.The ratio of the contact point area displayed after research is specified in Table 3,or the number of contact points in a 25mm x 25mm square area is specified in Table 3,and the number of contact points between any 25mm x 25mm should not exceed 5.

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

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 casting surface of the cast iron T-groove platform should be sandblasted and flat,and painted firmly.

5.There must be no defects such as sand holes,pores,cracks,slag inclusions,shrinkage,scratches,bumps,rust spots,etc.that seriously affect the appearance and performance.

6.The flatness tolerance of the working surface of the cast iron T-groove platform is specified in Table 2.

7.Scraping process should usually be used.The maximum allowable value of surface roughness Ra for a level 3 flat working surface processed by scraping is 5um.

Formula for calculating flatness:

Level 000:1 x(1+d/1000)Level 1:8 x(1+d/1000)

Level 0:2 x(1+d/1000)Level 2:16 x(1+d/1000)

Level 0:4 x(1+d/1000)Level 3:40 x(1+d/1000)
