Honing creates a precise crosshatch pattern on cylinder walls that retains oil for piston ring lubrication. The pattern angle (typically 22-32° included angle) is critical for oil retention, ring seating, and engine longevity. Every automotive engine cylinder is honed.

Honing uses abrasive stones that conform to the bore surface, correcting roundness, taper, and bellmouth. Grinding uses a rigid abrasive wheel. Honing produces a characteristic crosshatch pattern ideal for lubrication. Grinding produces a unidirectional finish. Honing is specifically for bores; grinding is more versatile.

Honing is a finishing process that typically removes 0.001"-0.010" of material per diameter. For production work, 0.002"-0.005" stock removal is common. Honing is not designed for bulk material removal — boring or grinding should bring the bore close to final size first.

The crosshatch angle is determined by the ratio of rotation speed to stroke speed. Engine cylinders typically use a 22-32° included angle. Steeper angles (45°+) provide more oil retention. Shallower angles provide better ring sealing. The optimal angle depends on the application.
