Dec 04, 2015 However, most CNC mill machines work with metal materials. Much like the processes of drilling and cutting, the appropriate CNC machine tools have to be chosen for each material being used. The density of the material at-hand, along with the rotation of the cutting tool, must be considered prior to starting the milling production process.
The hammer mill design is very robust and is used in many applications, from grain milling to heavy duty requirements such as rock crushing or waste grinding. Hammer mills are part of the impact mill family, which means that the milling effect is obtained thanks to the speed at which particles are impacted, here, by one or several rotors. 2.
