Abstract
A power tool system comprises (i) at least one power tool, in particular a circular saw, having at least one tool support unit for supporting a tool during machining and at least one displaceably mounted tool guiding unit, and (ii) at least one power tool separation device which is arranged on the tool guiding unit. The power tool separation device comprises at least one cutting unit and at least one guide unit for guiding the cutting unit.
Claims17
A machine-tool system comprising:
- at least one machine tool including at least one workpiece-bearing unit configured to support a workpiece during machining, and a drive unit operably coupled to at least one movably mounted tool-guide unit, the tool-guide unit having a transmission unit arranged at least partially within a tool-guide rod of the tool-guide unit, the tool-guide rod slidably received within a tool-guide bearing block, the movably mounted tool-guide unit pivotably attached to the at least one workpiece-bearing unit and pivotable about a pivot axis which is perpendicular to a bearing surface of the at least one workpiece-bearing unit;
- and
- at least one machine-tool severing device removably arranged on the tool-guide unit, wherein the machine-tool severing device includes at least one cutting strand and at least one guide unit configured to guide the at least one cutting strand, the cutting strand having an internal circumference smaller than an external circumference of the at least one guide unit, such that the at least one cutting strand is retained on the at least one guide unit when the machine-tool severing device is removed from the tool-guide unit, wherein the at least one machine-tool severing device, in at least one operating state, is mounted such that the at least one machine-tool severing device is displaceably guided by the tool-guide unit at least essentially parallel to a bearing surface of the at least one workpiece-bearing unit.
A machine tool for a machine-tool system, comprising:
- at least one workpiece-bearing unit defining a plane and configured to support a workpiece during machining;
- a drive unit supported by a movably mounted tool-guide unit pivotably attached to the at least one workpiece-bearing unit and pivotable about a pivot axis which is perpendicular to the plane defined by the at least one workpiece-bearing unit;
- and
- at least one coupling device operably coupled to the drive unit and configured to couple directly to a machine-tool severing device having at least one cutting strand, a transmission element configured to drive the at least one cutting strand, the transmission unit arranged at least partially within a tool-guide rod of the tool-guide unit, the tool-guide rod slidably received within a tool-guide bearing block, and at least one guide unit configured to guide the at least one cutting strand with the at least one cutting strand having an internal circumference smaller than an external circumference of the at least one guide unit, such that the at least one cutting strand is retained on the at least one guide unit when the machine-tool severing device is removed from the tool-guide unit, the at least one coupling device configured to move in a straight line along a movement axis parallel to the plane, wherein the drive unit is configured to couple with the transmission element to transmit torque to the transmission element.
