Estimating the term…
A hand-held electric machine tool (1) with an at least partly rotary-driven tool receptacle (2) for a tool and a press switch (5) arranged at a handle (4) on the workpiece side for activating the connection of a power source (6) to an electric motor (7) connected to control electronics (10) which are connected to a force sensor (8), wherein the force sensor (8) is arranged between the tool receptacle (2) and the handle (4) and is designed for measuring a pressing force (F) of the hand-held electric machine tool pressing against a workpiece. In addition, an intuitive control process for the hand-held electric machine tool (1) is claimed.
A hand-held electric machine tool with an at least partly rotary-driven tool receptacle (2) for a tool and a press switch (5) arranged at a handle (4) on the workpiece side for activating the connection of a power source (6) to an electric motor (7) connected to control electronics (10) that are connected to a force sensor (8), wherein the force sensor (8) is arranged between the tool receptacle (2) and the handle (4) and measures a pressing force (F) of the hand-held electric machine tool pressing against a workpiece.
A control process for a hand-held electric machine tool (1) with a first at least partly rotary operating mode (I) for rotating a tool receptacle (2) for a tool, wherein the control is activated in a first step by actuating a press switch (5) arranged on the workpiece side of a handle (4) and, in a second step, the control controls the electric motor (7) depending upon a force measured by the force sensor (8), wherein the force is correlated with the pressing force (F) with which the hand-held electric machine tool (1) is pressed against the workpiece.
