Feed rate

Normally a feed cassette can define two different feed rates. By turning the feed cassette 180 degrees you can change the feed rates, as shown in the figure below. The feed rate of the drill must be balanced with the spindle speed. Select from the available combinations of feed rates in the table below to get the desired feed rate.
