Grinding Ratio | ScientificNet

The maximum grinding ratio (1800) is equivalent to the average grinding ratio of the Japanese grinding wheel The grinding ratio is also maintained up to 26 cutting hours The good grinding surface was achieved with the average Ra of 25μm In addition, the bonding of cBN abrasive to the wheel body was observed with scanning electron ....

G-Ratio - an overview | ScienceDirect Topics

Mar 03, 2012· The grinding ratio G is defined as the volume of material removed divided by the volume of wheel wear (53) G = V m V s G ratio Example 52 After grinding a depth of 40 μm (or 00016 in) from a workpiece 1 m long (or 3937 in), the grinding wheel of 170 mm diameter (or 669 in) is found to have worn by a depth of 1 μm (or 0000039 in)...

A killer combination for ideal grinding conditions ,

Oct 31, 1998· In this equation, G is the grinding ratio, which is defined as the volume of material removed per unit volume of wheel wear G increases with less wheel wear and/or higher metal removal The higher it is, the better the grinding conditions, especially in terms of longer wheel life To determine G, one takes the equation: G = Vw/Vs...

What is grinding ratio (G) - Manufacturing Processes - 2

Aug 04, 2015· - The grinding ratio is defined as the ratio of the volume of material required to the volume of wheel wear G = (the volume of material required) / (the volume of wheel wear) - The value of grinding ratio is usually about 10 to 60 for fine grinding operations like horizontal surface grinding - Whereas, for rough grinding operation, the value ....

Grinding ratio | Article about grinding ratio by The Free ,

Grinding ratio (GR) is calculated as the ratio of weight loss of material to the weight loss of abrasive wheel for a specific grinding time Although it can be ground with pure silicon carbide wheels, the grinding ratio is very low and the material is easily damaged...

Grinding Ratio for Evaluating Grinding Wheel Performance ,

Grinding ratio is the quick method of evaluating the grinding wheel performance Grinding operation removes metal very delicately, leaving a finished surface of superior dimensional accuracy and good surface texture If it is carried out properly, there will be very less metallurgical damage due to the rise of pressure and temperature of the ....
