Surface quality

Surface quality describes the quality, uniformity and roughness of a machined surface. It is crucial for the appearance, function and further processing of a workpiece.

What influence does the grinding process have on the surface quality?

• Fine surfaces require multiple grinding steps
• Each grinding step affects the next
• Abrasives must work evenly

Typical problems concerning surface quality:

• Visible grinding marks
• Marking/shading
• Grinding marks from previous steps

What must be kept in mind with regard to surface quality?

• Follow a strict grit size order
• Consistently maintain grinding direction
• Change the abrasive in good time
