What applications commonly call for honing?

Engine cylinders and cylinder sleeves require honing for proper piston ring sealing. Diesel engine fuel system components are often honed because honing enables tighter control of the clearance between the bore and its mating part. The resulting higher fuel system pressure means more fuel is atomized and less unspent fuel is used, resulting in improved fuel efficiency and engine performance as well as lower carbon emissions.

What bore conditions can honing help?

Quite a number, including bore diameter size, bellmouth, waviness, taper, rainbow, barrel shape, reamer chatter, boring marks and out-of-round holes. The improved shape of the bore after honing almost always results in mating components operating more quietly and efficiently. Honing can correct errors caused by previous machining processes because it does not require chucking or alignment and is indifferent to bore length.

What types of surface finishes can honing achieve?

Surface finish, texture and appearance can be precisely controlled. The angle of the crosshatch pattern can be adjusted by varying the spindle speed and stroke speed of the honing tool. Some applications call for a steep crosshatch angle in the bore, while others require a shallow angle. The depth or roughness of the crosshatch pattern depends on the relative size of the abrasive grit in the honing stone. The larger the grit, the rougher the finish. A mirror finish with almost imperceptible surface texture can be achieved with very fine grit abrasives.

What is involved in establishing an effective, consistent honing process?

Like CNC machining, a number of questions must be answered when developing an optimized honing process. What is the part material, size and shape? What is the production volume? How much material needs to be removed? What are the finished workpiece bore tolerances and surface finish requirements? Answers to those and other questions determine the proper machine, fixtures, tooling, abrasives and honing oils or coolants, as well as honing process parameters such as spindle and stroking speeds and feed rate. The honing stone is selected based upon the type of material to be honed, tolerances to be achieved and the amount of material to be removed. There are as many types of abrasive honing stones available as there are types of milling or turning cutters, differentiated by grit material, grit size and bonding agent.

How does lubrication affect honing?

Honing oils and water-based coolants provide needed lubrication, washing away cut material and bringing new abrasive grit to the surface of the stones to maintain optimum cutting action. Quality oils, saturated with surface active agents, provide the necessary lubricity to increase honing pressure and use harder abrasives at faster cutting rates. Similarly, lubricity agents combined with sulfur extreme-pressure additives prevent workpiece welding and tearing while keeping stones clean, resulting in a very consistent surface finish.
