1. A sliding cutting machine comprising:
a turntable configured to support a workpiece while the workpiece is being cut;
a main body support arm that is pivotable relative to the turntable about a tilt pivot axis,
a first slide bar and a second slide bar extending from the main body support arm, the first and second slide bars having an elongated shape and a longitudinal axis spaced from and parallel to the tilt pivot axis, each of the longitudinal axes lying in a first virtual plane;
a slide base slidably mounted on the first and second slide bars; and
a cutting-machine main body mounted on the slide base such that the cutting-machine main body is movable in an up-down direction relative to the slide base and the first and second slide bars;
wherein the cutting-machine main body comprises:
an output shaft extending in an axial direction that is orthogonal to the first virtual plane;
a cutting tool mounted on the output shaft; and
an electric motor having a motor shaft, an entirety of the electric motor being disposed between the cutting tool and the first and second slide bars, as viewed along the longitudinal axes of the first and second slide bars while the cutting tool is vertical,
the first slide bar is arranged above the second slide bar in the up-down direction when the cutting tool is vertical,
the first and second slide bars and the main body support arm are tiltable about the tilt pivot axis relative to the turntable to change a bevel cut angle of the cutting tool, and
the cutting tool and the electric motor are entirely located on a same side of the first virtual plane.
