Grinding is possible at multiple gradations of roughness. The roughness value of the product surface is indicated by a number. Generally, the average roughness is considered for this purpose, indicated with 'Ra'. The desired roughness is related to the application of the product. Whether it should be free from attached micro-organisms ...

To achieve this, ANCA has developed a process on its MX7 Linear machine that applies a series of grinding, honing and final buffing operations. The result is surface finish on the ball of <0.01µm Ra and part roundness under 3µm. Figure 2: surface finish measurement of finished ball is <0.01micron Ra.

The wet end felt rolls of a paper machine typically have an Ra value between 30-50. These rolls are used to support the rotating wet felt, which carries paper pulp into the press section. Having the rolls between 30 Ra and 50 Ra gives enough roughness for the felt to drag along the roll without causing slippage.

Ra values were very close to each other in every part of the ground workpieces. According to the modeling results, the spindle speed had the highest effect on Ra, followed by the depth of cut and the type of grinding wheel. GMASRA is also very cost effective and can be adapted to most milling machines and CNC milling machines.

Grinding machine-related factors can affect the workpiece surface finish. These include: Wheel/hub assembly balance: If the grinding wheel assembly is not balanced to an acceptable level, it can result in chatter and/or poor surface finish. Balancing can be carried out using equipment such as a static balancer, dynamic/manual balancer, or an ...

Vertical grinding takes the principles of traditional grinding and turns it on it's 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.
