Apr 07, 2015 What is Ra? According to an article in Modern Machine Shop written by George Schuetz, director of precision gages at Mahr Federal, Ra is calculated by an algorithm that measures the average length between the peaks and valleys and the deviation from the mean line on the entire surface within the sampling length. Ra averages all peaks and valleys of the

The grinding precision of the cylindrical grinding machine is generally roundness does not exceed 3m, surface roughness Ra 0.63 0.32 m high precision cylindrical grinding machine can reach roundness 0.1 m and Ra 0.01m respectively.
Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min 1, although in high-speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface grinding.
Belt grinding and polishing are very flexible machining processes with undefined cutting edges that use a large number of cutting particles. Depending on the abrasive belt selected, extreme high stock removal rates (1 mm and more per pass ) or super fine finishes can be achieved (Ra 0,1 m and better).
Jun 30, 2009 Surface Roughness Produced by Different Manufacturing Process. Knowing what manufacturing process can produce surface finishes that desired on a surface can be an added advantage while making the designs. Here is a table showing maximum and minimum Ra values can produced on each production methods. Elect. Discharge Machining. Perm. Mold
The grinded surface using a coarse dressed grinding wheel was improved from Ra 0.072 m to Ra 0.042 m after magnetic abrasive finishing. The surface roughness after grinding using a fine dressed grinding wheel showed a roughness of Ra 0.035 m and could not be improved after the MAF-process. However, a new surface topography was produced.
Vertical grinding takes the principles of traditional grinding and turns it on its side. In this process, the workpiece is fixed to the bottom of the machine and the grinding wheel moves down to grind the piece. The wheels are also capable of axial rotation, which means they can rotate and grind lips and bevels.
