UTENSILE AUTOMATICO AVENTE UN'IMPUGNATURA PER CONTROLLARE L'AVANZAMENTO DI UN UTENSILE TAGLIENTE COME UNA PUNTA DA TRAPANO E/O SIMILI

摘要

The power tool has a magnetic base with superimposed permanent magnet assemblies. The upper assembly can be moved relative to the lower assembly to shunt or reinforce the magnetic field. When the sensing probe is pushed into the base the electric motor can be switched on to rotate a spindle on which a rotary cutting tool is axially mounted. The tool feed is controlled by a handle which can be mounted on either side of the tool housing. A coolant reservoir on the base has a hose connected to a pump which is connected to a manifold supplying coolant to the interior of the cutting tool. The cutting tool is biased upwardly and pinches off the coolant when the tool is raised from the work.
