With the in-feed method, the regulating wheel spins the part at one speed while pushing it towards the grinding wheel, which is spinning at a faster speed. The greater the difference in speeds, the faster the removal rate. 4. The choice of grinding wheel is critical. Another key factor in centerless grinding is the choice of grinding wheel.

The basic purpose of grinding coffee beans is to facilitate the extraction process by exposing more surface area to the hot water. Basically, the process of making coffee happens as roasted coffee beans are brought into contact with hot water that 'extracts' the flavour, ideally resulting in a delicious cup of brew.
