Document Type and Number:
Japanese Patent JP4656376
Kind Code:
B2
Abstract:
A miter saw including a base, a turntable, a support section extending from the turntable, and a circular saw unit supported to the support section and having a circular saw blade. A laser oscillator is disposed at one of the support section and the circular saw unit so as to irradiate a laser line on a surface of the workpiece mounted on the turntable. The laser line on the surface of the work-piece is located within a width defined between loci of opposite side surfaces of the circular saw blade, or immediately beside and along the width. A cut-marking line is drawn on the surface of the workpiece. By adjusting angular rotation of the turntable, the laser line can be aligned with a cut-marking line drawn on a top surface of the work-piece for angled cutting. By adjusting laterally tilting position of the circular saw unit, the laser line can be aligned with a cut-marking line drawn on an approximately vertical surface of the workpiece for slant cutting. An adjustment unit and a tilt amount fine control unit are provided for performing fine control to the rotation angle of the turntable and tilting angle of the circular saw unit, respectively.
