Hoffmann Dovetail Jointer MS35SF
(Combination Double-Mitre-Saw, and routing unit the latest generation of this particular mitre saw)
The MS35SF helps to improve the quality of the joint, by cutting and routing each joint simultaneously. Thereby reducing handling time and increasing production.
Pneumatically operated with 2no. saw-motor units and 2no additional router-motor units. Simultaneous production of two exact mitre cuts followed by routing of either one or two dovetail slots in each side of the cut mitres.
to function only as a double-mitre-saw.
to function as a double-mitre-saw and dovetail router.
two dovetail positions
position one (single dovetail)
position two (single dovetail)
All options are selected by the switch positions on the control panel.
Changes of the dovetail slot, within the mitre cut are made manually. Digital clocks on each adjustment position determine exact positions. Thereby simplifying changes and reducing set-up time.

Description of operation.
After positioning the square end of the profile into the machine and operating the dual-hand control, the material is clamped and then cut from above in an exact 45° mitre. The tables open, to allow the router units to cut one or two router slots in the cut face of the profile. The profile is then passed through the machine to a fence-stop (digitally positioned), the machine is again activated, material clamped, double saw cuts made, router slots cut and material released. Each cycle of the machine produces a section with a mitre on each end with router slots made for Hoffmann Keys.
