A cnc double driller is a machine that cuts two profiles at the same time. These two profiles can be used to construct one polygon, or a whole range of shapes. This will help avoid any errors while constructing something with multiple parts that need to fit perfectly
An example of this is when you're making a mold for casting metal parts. In this case, you would have a profile for each part you want to make. You would cut out those profiles with a CNC router or milling machine and then use them as guides for your CNC router or milling machine to cut out the rest of your mold
This type of equipment is also helpful for cutting other types of materials besides metal like wood and foam board as well as plastic and composite materials like carbon fiber or kevlar etc..
