Internal grinding machines. Internal (cylindrical) grinding machines are used to create consistent and accurate internal radii. They work using roll-shaped grinding bodies. The internal grinding machines available today feature computerised numerical control (CNC) and can thus achieve the strictest of tolerances.
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
THREAD GRINDING-Produce very accurate threads on hardened materials-Three basic methods are used. 1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ).

29.3 Internal grinding machine This machine is used to produce internal cylindrical surface. The surface may be straight, tapered, grooved or profiled. Broadly there are three different types of internal grinding machine as follows: 1. Chucking type internal grinder 2. Planetary internal grinder 3. Centreless internal grinder
When the area of contact in grinding operation is large, total grinding pressure is distributed over a larger area and the pressure per unit area is less and hence a softer wheel is needed for it. Thus for internal grinding where arc of contact is more, softer wheel is used and for external grinding, harder wheel. Condition of Grinding Machine:

Internal grinding is an abrasive process that removes material on the inside diameter (ID) of tubes or the ID of part features such as bores or holes. Along with honing, ID grinding is used to create smooth surface finishes and tight tolerance on IDs.
Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
