Honing is a type of abrasive process typically used to finish the interior of a cylinder. Rather than using an abrasive wheel as in grinding, a hone uses several flat stones arranged around a mandrel that moves in and out of the hole. For vertical or horizontal honing, the tool reciprocates through the hole, while in a single-pass finishing ...Web

1 – Taper. Whether it is an I.D. or O.D. operation, taper is one of the most common problems in grinding and finding the cause can be tough. In some cases, it is as simple as adjusting the oscillation stroke to be longer or shorter to compensate. In others, dressing a reverse taper into the wheel may be the best way to handle things.Web

Machines used for cylindrical grinding – a process used to finish off the outside or inside diameter of a cylindrical part – are a mainstay of many metalworking shops. With cylindrical grinding, both the workpiece and the grinding wheel are constantly rotating, as the grinding wheel is fed towards and away from the piece.Web

Alternatives to Bore and Face Grinding. However, for parts with smaller diameters and relatively deep bores (length-to-diameter ratio of 2:1), honing has a real advantage in speed of material removal. For bores with a length-to-diameter over 5:1, deflection of the grinding spindle will cause the bore to taper. If a finer, bearing like …Web

Mastering the Art of Cylinder Bore Honing. 38.
