The performance of grinding process is conditioned by a number of factors related to the characteristics of the workpiece, grinding wheel and its properties, cutting mode, cutting forces, heat output, etc. This paper aims to make a model of the grinding process of carbide drills for deep holes of small diameter.
In grinding process, ore grindability, feed particle size, product fitness requirement, ball mill specification and type, liner shape and grinding media are all influential factors. In ball mill, pulley and gear reduction mechanism is the key factors for cylinder rotating speed which is generally fixed.

Basic Principles of Deep Rolling. A workpiece can be deep rolled in one setting directly after machining. Setup and transportation costs can be eliminated. This process can be used with a wide variety of components to increase fatigue strength or enable lightweight design solutions.
Practical Roll Techniques: Grinding Balancing. Executive Summary. Consistent grinding and balancing of rolls is necessary for efficient operation and optimum paper quality. As an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment.
In highefficiency deepcutting grinding, the cutting depth is to 30 mm, the workpiece velocity is to 10 m/min, and the wheel velocity is 80 to 200 m/s [18,19]. High metal removal rate and high surface quality can be obtained with it.
However, even being the grinding process the most used in industry for obtaining high level of surface quality, it remains as one of the most difficult and least understood processes (Wang et al., 2005).
An abrasive belt grinding process is a variation of the longestablished grinding processes, where the tool is made up of the coated abrasive belt and rotating polymer contact wheel assembly as shown in Fig. 1.
Mill (grinding) Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material. For instance rock crushing or grinding to produce uniform aggregate size for construction purposes, or separation of rock, soil or aggregate material for the purposes of structural fill or land reclamation activities.

ME 383 Exam 3 CH 25: Grinding and Other Abrasive Processes. The mechanisms are (1) grain fracture, in which a portion of the grain breaks off during cutting; (2) attritious wear, in which the grains become dull during cutting; and (3) bond fracture, in which the grains are pulled out of the bonding material.
