Condition of surface
Pattern class N • Typ 4
Surface cutted at the smallest possible feed on the turning machine.
Feed grooves are visible and sensible.
Pattern class Q • Typ 3
Marks and structures of the grinding-wheel are recognizable and visually perceptible.
Pattern class H • Typ 2
A structure such as is caused by the turning machine.
Slight grinding and feed marks may be visible but not sensible.
Pattern class P • Typ 1
Grinding and feed marks and scratches are not visible to the eye.
Individual abrasive Commas are allowed.
Not all materials can be produced in this quality.
Pattern class • Typ S
Roller surface with a specially agreed structure.
