Problem solving: measuring the hardness gradient of the surface of large works and the crystallity of the product.

The client is currently having problems: testing with another miller, which can have different sides from grinding to polishing. By grinding the heads and grinding plates in the same direction or in the opposite direction, the pressure is down, and the turn is down.

Reason: The sample is too mosaic, 40 mm in diameter, the sample has a large grinding and eject, and the edge of the sample is very hard, requiring a high degree of mosaic. If the pressure at the centre of the grinder is uneven, the sample will have a high- and down-to-surface jump during grinding and multiple-faced.

Fuyun solution: adjust the centre pressure to even it.

Grinding: Fuyun gold sandpaper 240#-600#-1200#    

Shine: Fuyun Xin  

Machine: Full automatic grinder

The following are the results:
