Machine the cylinder head mating surface
The height (H) of the cylinder head cannot be lower the minimum value after grinding.
Grinding details: Rotation n = 1400/min (rpm) Longitudinal advance 800-1000 mm/min Vertical Advance (each pass-through) 0.03 mm Cutting speed Vs = 27 m/s Grinding wheel diameter d = 370 mm Sivat grinding wheel type 39C 36 F8 VK Norton 39C 36 F8 VK.
The rotation (n) is determined by the diameter (d) of the grinding wheel; n = (Vs. 1000 . 60) : (d . 3.1416).
