 The main advantage of PCB milling is the quick turn around time, hence milling is best used for rapid PCB prototyping.
+Currently the machine is not set up for: Special operating conditions or heavy work pieces may require that the machine is encapsulated. A protection cover is available
+as an option. Also additional work piece clamps will need to be made/purchased.
