Honing for machining hardened steel

General cutting

GA Honing : General machining
GS Honing : Vibration and burr control
GN Honing : If the crater wear is large.
GH Honing : For depths of cut of .006 inch or greater

Continuous cutting, stable cutting

FS Honing : General machining
FA Honing : For improved biting compared to FS
FN Honing : if the crater wear is large.

Medium and heavy interrupted cutting, unstable cutting

TA Honing : General machining
TS Honing : Vibration and burr control
TN Honing : If the crater wear is large.
TH Honing : For depths of cut of .006 inch or greater

Honing for machining sintered alloys

Continuous cutting, stable cutting

FS Honing : Continuous cutting, General machining

Medium and heavy interrupted cutting, unstable cutting

GS,TS Honing : If fracturing occurs at the blade edge during interrupted cutting

Focus on high-precision cutting, dimensional precision, and surface roughness

SF Honing : Focus on finished surface roughness
SE Honing : If chipping occurs
