Used to remove material from internal cylindrical surfaces to improve part geometry or produce a finer surface finish, honing is performed at a much slower speed than is typically used in Precision Grinding.
The cutting action is achieved by a rotating hone, or stone, which is bonded with a very fine abrasive grit and mounted on a metal mandrel. Rather than being clamped in place, the workpiece is fixed to allow floating and prevent distortion that would result in an oval rather than round hole.
The hone is rotated in a controlled path over the surface of the part. In some cases, a machinist might move the workpiece back and forth over the rotating hone, ensuring that the part is floating rather than being pressed against the hone - again, to avoid an oval hole.
With a horizontal honing machine, the workpiece may be held in a self-aligning fixture while the machine controls the speed and length of the stroke. The hone is hydraulically or mechanically expanded until the desired hole diameter is achieved.
In addition, a cutting fluid must be used. The purpose is threefold: to clean small chips from the work area, to cool the workpiece and hone, and to lubricate the cutting action.
Lapping is used to achieve surfaces that are very flat and smooth, as well as to finish round work, such as precision plug gages, to very tight tolerances.
The lapping process is more gentle than honing and removes much less surface material. Therefore, the workpiece should be as close as possible to final size - achieved, for example, through double-disk grinding - because lapping typically removes only 0.0005" to 0.005" (0.0127 mm to 0.127 mm) of material.
Unlike honing, lapping uses fine-grained, loose abrasive particles suspended in a viscous or liquid base rather than a bonded abrasive stick or stone. The lapping process involves passing the workpiece between one or two large, very flat lap plates along with the abrasive suspension.
With lapping, close attention is paid to controlling every detail. This includes the speed of the plate(s), the pressure on the workpiece, the size and type of abrasive used, the feeding method, and the plate temperature.
