1.Single-stroke machines hone a bore in a single stroke instead of oscillating. Standard tools handle bores from 6 to 50 mm, although other sizes can be manufactured that are smaller or larger. An abrasive is plated on a split sleeve that fits over a tapered arbor. The position of the sleeve on the arbor determines the diameter to be honed and is initially mechanically set, usually with a threaded pilot.

Single-stroke machines are used chiefly on cast iron and powdered metal parts such as valve components or certain gears. Various types of steel, both hard and soft, are also single stroked successfully. The main advantages of single-stroke machines are high production rates with rotary table index machines and long tool life.

2.Multistroke machines use a single rotating spindle that carries one or more abrasive stones. Standard tools are used on diameters ranging from 1.5 mm to 60". Larger and smaller tools can also be made. The workpiece or the tool can be stroked. Materials from alnico to zirconium can be honed. Typical applications include gears, valve spools, drill bushings, die bushings, engine cylinders, and landing gear. Main advantages include removing large amounts of material quickly (as fast or faster than ID grinding) to a tightly controlled finished diameter size, cylindricity, and surface finish. Abrasive sticks continuously abrade during the multistroke honing process which exposes sharp abrasive grits throughout the life of the stone. Because of the multiple stroking action, a helical crosshatch pattern is generated within the bore which provides an ideal surface for lubrication between the bore and a mating part.
