Lapping generates flat surfaces (geometry refinement) with extremely fine finishes using lapping compound, where parts are processed between one or two large flat lap plates or platens. Lapping is a gentle surfacing process using low speeds (80 RPM) and low pressures. Compared to grinding and honing, lapping removes much less material.

Cylindrical grinding aluminum. I've been asked at work the feasibility of cnc cylindrical grinding some aluminum parts. Material is either 6061 or 7075 likely T6 temper (I was not given more details than that). The parts are about 113" long and the OD is a little over 5". The entire OD needs to be ground to 5.XXX" +/- .001".

Honing and Honing Alternatives. Honing is a high-precision process used to improve form characteristics such as cylindricity and surface finish. Honing is used to improve the geometry of a part, adjust the alignment of features such as holes or bores, and, in some cases, produce a specific surface finish on the interior bore.

B.E. Bore Grinding is a large and diverse area of manufacturing and tool making. It can produce very fine finishes and very accurate dimensions; yet in mass production contexts it can also rough out large volumes of metal quite rapidly. It is usually better suited to the machining of very hard materials.

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can

On its face, bore grinding seems like a simple operation. You send a spinning wheel inside a spinning part and oscillate it back and forth until the desired dimensions and surface finish have been achieved. Unfortunately to reach into the part, the wheel must be mounted on a quill (sometimes long…in essence, a cantilever).

Lapping is a sanding or polishing method used to create an accurate finish on a flat or domed surface of a part. Honing is a method of internal grinding used to achieve a precise surface finish and shape on the inside diameter (ID) of a tube, bore, or hole. The honing and lapping processes are both highly controlled.

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

These processes start with solid blocks, bars, or rods of metal, or plastic that are shaped by removing material through cutting, boring, drilling, and grinding. Unlike most other plastic manufacturing processes, CNC machining is a subtractive process where material is removed by either a spinning tool and fixed part (milling) or a spinning ...

Boring is a cutting process that involves the use of a single-point cutting tool or boring head to enlarge an existing hole in a workpiece. This is in stark contrast to drilling, which is performed to create an initial hole in a workpiece. Boring processes are typically performed using a lathe, milling machine or a horizontal boring mill.

Truing is the process of changing the shape of the grinding wheel as it becomes worn from an original shape, owing to the breaking away of the abrasive and bond. This is done to make the wheel true and concentric with the bore, or to change the face contour for form grinding. Truing and dressing are done with the same tools, but not for the ...
