The main operating parameters of the sand mill. Sand mill flows: It affects product fineness, output, and particle size distribution. Flow rate and output are two different concepts. In the continuous grinding process, the absolute value of the two is equal. In cyclic grinding, the output is 1/n of the flow rate (n cycles).

operations. Facing is used for machining a large flat area, typically the top of the part in preparation for other milling operations. A face mill is a solid body that holds multiple carbide inserts that can be replaced as they wear out. The more inserts, the faster the metal removal rate. Cutters with a 45 lead angle are used most frequently.

During contour milling we recommend a lateral infeed of approx. 25 % of the end mill diameter while applying 100 % immersion depth. The immersion depth is conditional to the milling motor, the structure and the stability of the machine. This means a reduction of the values is required, when using a less powerful and / or lighter milling motor.
