Problems solved by technology
However, the scale may be covered with cutting debris generated during cutting, reducing the visibility of the scale
[0005] In addition, in the case of manually rotating the rotary table to the desired scale position will cause inevitable errors
For example, it would be very difficult to precisely set the rotational position of a turntable at a rate of 0.1 degrees
[0006] In addition, in order to ensure cutting stability for cutting wood blocks with a relatively large cross-sectional area, it is necessary to increase the size and weight of the miter saw
As a result, it becomes more difficult to precisely set the turntable at the desired angle within 1 degree or less
Therefore, positioning the turntable precisely at the desired angular position of rotation is time-consuming and requires skill

Embodiment Construction
[0061] The following will refer to Figures 1 to 31 , 46 and 47 illustrate a miter saw according to a first embodiment of the present invention. Such as figure 1 As shown, a miter saw 1 includes a base portion 2 mounted on a stand or on the ground for fixing a workpiece such as wood thereon, a circular saw unit 4 for cutting the workpiece, and a supporting circular saw portion 4 pivotally movable to and from A support portion 3 remote from the base portion 2 and inclined laterally relative to the base portion.
[0062] Such as figure 1 As shown, the base part 2 includes a base 11 as a floor part, a turntable 21 and a protective plate 12 . The turntable 21 is supported on the base 11 and rotates relative to the base 11 around its axis. The turntable 21 supports a workpiece such as a block of wood together with the base 11 . The protective plate 12 extends laterally on the base 11 and is supported on the base 11 . The shield 12 has a laterally extending abutment surface an...

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. An adjustment mechanism is provided between the base and the turntable for performing fine-adjustment to the rotation angle of the turntable relative to the base. The adjustment mechanism is located at a front side of the turntable, and a digital display is provided near the adjustment mechanism for displaying the rotation angle.
Description
technical field [0001] The present invention relates to a miter saw, and more particularly, to a miter saw capable of performing an angled cut in which a side surface of a circular saw blade extends obliquely with respect to a guard plate. Background technique [0002] In a conventional desktop circular saw, a workpiece such as a block of wood is fixed on a base portion, and the workpiece is cut by a circular saw unit vertically movable on the base portion. If the workpiece is to be cut obliquely, the orientation of the workpiece on the base portion must be changed. Therefore, workability is lowered. [0003] Japanese Patent Application Laid-Open Application No. 2000-254817 discloses a miter saw including a base portion, a support portion, and a circular saw unit. The base part includes a base and a turntable fixed on the base and rotating around its axis. The workpiece is fixed on the rotary table. The support portion extends upward from the turntable and slopes sideway...
