Both standard brush-style router motors have been replaced with production-duty High-Frequency Router Motors for extended service life, reduced maintenance and higher production levels. Production-duty, freestanding two-head dovetail routing machine with solid cast aluminum table and heavy steel frame. Machine is designed to rout a single dovetail keyway into two work-pieces with each machining cycle. For Dovetail Keys sizes W-0,W-1, W-2, W-3, and W-4.
Large work surface is designed to be at a comfortable working height, the router motors are controlled by a contactor and a 4” dust collection port is located at the back for connection to a central dust collection system.
The keyway locations are adjusted by positioning the guided center fence plate on the machine table; the keyway lengths (routing heights) are adjusted by setting a height-stop rod to the desired setting.
Routing height adjustment road with scale
Pressing the pneumatic foot pedal starts the machining cycle:
Pneumatic clamps secure both work-pieces and motors are switched on
Router heads advance until pre-set height is reached
Router heads return to home position and motors are switched off
Pneumatic clamps release work-pieces
Output is approx. 16 routing strokes per minute, which translates into 4 completely processed rectangular frames. These numbers include material handling, but obviously depend on routing depth, feed speed, material flow and operator performance as well. Flow control valves on the main pneumatic cylinder allow the operator to adjust the upward and downward feed rate independently, depending on the material being processed. A 4″ diameter dust collection port in the back is used to connect a central dust collection system.
The supplied router bits are solid tungsten carbide, made to exacting specifications. Depending on the routing depth and the material to be routed, the useable cutter life is approx. 10,000 strokes, often times even more. Every machine is shipped with a tool kit and set-up jig, which allows a router bit change in only minutes.
