The rigidity of grinding machine is generally higher than milling machine, and its vibration signal is weaker than milling, so the signal processing method is required to have higher sensitivity,,, especially the grinding chatter is more difficult to detect when harmonic of forced vibration in the process of high-speed grinding mixing with ...
Belt grinding has become an important production process, in some cases replacing conventional grinding operations such as the grinding of camshafts. Belt speeds are usually in the range of 2,500 to 6,000 ft/min. Machines for abrasive-belt operations require proper belt support and rigid construction to minimize vibration.
For surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface.Higher values of any of them would result in a higher material removal rate, and therefore, a higher rate of generation of thermal energy.
Disadvantages of Grinding Operations: Required tool is high cost. Process is also a costly one. It cannot remove the high amount of material, it only removes a little amount. For removing the required amount from work it consumes more time. You should work carefully, because imperfect contact may lead to damages.
