Keep Your Cylindrical Workpieces Running UNITED GRINDING

One of the biggest sources of roundness errors in cylindrical grinding involves the centers that hold your work in place. Like the small contact patches through which vehicle tires establish traction on a road, the centers that enable workpiece rotation make contact with the part through the small tips of a pair of cone-shaped metal points that match up with corresponding centers on the workpiece itself.

A quantitative analysis of roundness error in cylindrical

Jan 01, 1981· For the purpose of developing a system for on-line control of roundness in cylindrical grinding, it became necessary to establish the major causes of roundness error. Hence, the objective of this paper is two-fold : (1) to develop a new on-line technique to simultaneously measure the spindle error motion and the roundness of the ground component ; (2) to quantitatively

Cylindrical grinder Wikipedia

There are five different types of cylindrical grinding: outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, and centerless grinding. OD grinding is grinding occurring on external surface of an object between the centers. The centers are end units with a point that allow the object to be rotated. The grinding wheel is also being rotated in the same direction when it comes in contact with the object. This effectively means the two surfaces will be

Circularity & Cylindricity Quick Guide to understand GD&T

For example, Bearing design requirement is to be perfectly cylindrical. Meeting this manufacturing requirement during mass production becomes difficult with tight tolerance control all over the cylinder. If we introduce Cylindricity here, we can ease the size tolerance and then do the grinding to refine only the cylindrical surface.

Centerless Grinding: Not Magic! Modern Machine Shop

Dec 15, 2000· In cylindrical grinding, understanding the process is relatively straightforward. A workpiece, supported by centers or a chuck, is rotated against the grinding wheel, which is fed in a prescribed distance radially (plunge grinding) or traversed axially across the workpiece to create the desired OD dimension. Creating roundness from out-of

Workpiece roundness profile in the frequency domain: an

In grinding, most control strategies are based on the spindle power measurement, but recently, acoustic emission has been widely used for wheel wear and gap elimination. This paper explores a potential use of acoustic emission (AE) to detect workpiece lobes. This was achieved by sectioning and analysing the AE signal in the frequency domain. For the first time, the profile of the ground

Cylindrical grinder Wikipedia

The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.

8 Principles of Centerless Grinding Metal Cutting

Dec 08, 2016· In-feed grinding — also called plunge grinding — is used to grind cylindrical parts with notches or complex shapes, such as gear shafts. Here, the workpiece rest blade needs to be tooled to match the shape of the part, and the grinding and regulating wheels must be dressed to match the part’s desired profile cut.
