We designed the structure of this sheet router specifically to cut stacked sheets. A heavy steel plate supports the table and internal braces provide rigidity. Throughout the structure we have weight where it is needed to provide stability and help dampen vibration. The Paradigm router is a purpose-designed high speed aluminum cutting router, not a modified wood router.



We use the latest generation Siemens linear motors that accelerate with 1G force. These powerful motors take the machine from dead stop to top speed of 4000” per minute in 2/10’s of a second, a critical advantage in hole drilling. With linear motors there are no parts to wear out, so there is very little maintenance required.



Stackmaster’s patented Groundhog clamps act in less than one second. This allows us to secure the stack by opening and closing the clamps without hesitation, keeping the cutter path clear. These clamps greatly reduce the nest border, thereby saving thousands of dollars in material every week.



Our patented clamp is specially designed for our system and its durability eliminates repair and maintenance worries. See the clamp in action.



Our table top is a vacuum chuck, which allows us to cut a single sheet at up to 600” per minute. With this speed you can quickly make only the parts you currently need. Although these parts show tabs, no tabs are required if the parts have a sufficient surface area for the vacuum to hold them in place. We used “O” condition material for all our tests, both stack and single sheet.
