Abstract:
1. A cutting device comprising: a table having a table surface for placing thereon a workpiece; a tool unit configured to support a cutting tool having a rotational axis; wherein the tool unit is laterally tiltably supported on the table, so that the rotational axis of the cutting tool can be inclined relative to the table surface, and a first positioning device comprising a first positioning member and a second positioning member that can interact with each other to position the tool unit at a plurality of laterally tilted positions; wherein at least one of the first and second positioning members can be moved to change the laterally tilted position that can be positioned by the first positioning device; wherein the at least one of the first and second positioning members is coupled to an operation member so as to be moved between a first position where the first and second positioning members interact with each other and a second position where the first and second positioning members do not interact with each other; a second positioning device configured to position the tool unit at a vertical position where the rotational axis of the cutting tool extends substantially parallel to the table surface; and a third positioning device configured to position the tool unit at a 45° tilt position where the tool unit is tilted laterally from the vertical position by an angle of about 45°; wherein the first positioning member and the second positioning member of the first positioning device are provided separately from the second positioning device and the third positioning device, and the plurality of laterally tilted positions being positioned between the vertical position and the 45° tilt position; wherein the first positioning member comprising a positioning lever pivotable in a plane perpendicular to a pivot axis of a bevel mechanism of the first positioning device is coupled to the first operation member so as to be moved between the first position and the second position, the positioning lever is capable of interacting with stopper members and can be finely adjusted; wherein the first positioning device further includes a first resilient member and a second resilient member each configured to bias the first positioning member toward the first position; and wherein the first resilient member and the second resilient member are attached to the first positioning member at different positions with respect to the moving direction of the first positioning member.
