MU3-P | Hoffmann | Dovetailers

Professional level, pneumatically controlled dovetail routing machine to rout a single dovetail keyway with each machining cycle. Heavy cast aluminum construction with large, ergonomically shaped table surface, precision linear bearings, galvanized steel motor carriage with integrated motor fine adjustment. For Dovetail Key sizes W-0, W-1, W-2, W-3 (W-4 with optional larger motor). This pneumatically controlled dovetail routing machine is the more automated version of the MU 3 and MU3-D models. Aside from the same attributes in terms of design and built quality, the machine features two pneumatic cylinders and a pneumatic foot pedal.One short stroke cylinder is used to clamp the material the instant the foot pedal is pressed, while a second, larger cylinder is used to move the router carriage up and down.The main benefits compared to the manual machines are faster and more comfortable operation, more consistent results due to set routing feed rates and the fact that both hands can remain on the material during the routing sequence. This is an important advantage when processing longer parts. The keyway location is adjusted by positioning the guided center fence plate on the machine table;the keyway length (routing height) is adjusted by setting a height-stop rod to the desired setting.
