Problems solved by technology

[0005] But people can think of the following situation: the above-mentioned high-frequency current generated near the motor is conducted through the cutting machine body and the metal components on the side of the workbench supporting it, and then is conducted by a flat surface with a large area. Amplified by the workbench, etc., it becomes noise that adversely affects other surrounding electronic equipment

Embodiment Construction

[0021] The following is based on Figure 1 ~ Figure 4 Embodiments of the present invention will be described. figure 1 It is an overall side view showing the cutting machine 1 in the embodiment of the present invention. In the illustrated embodiment, as an example of the cutting machine 1 , a sliding circular saw as a desktop cutting machine is exemplified. It allows the cutting machine body 20 to slide back and forth. exist figure 1 , the user is located on the right side of the cutting machine 1. In the following description, the user side ( figure 1 The middle right side) is the front side, the side away from the user ( figure 1 Middle left) is the rear side. In addition, the left and right directions are based on the user. In a normal cutting operation, the user moves the cutter body 20 from the near side to the rear side to perform cutting. Therefore, the direction towards the rear side is also referred to as the cutting travel direction.

Abstract

In a cutting machine, such as a table-top circular saw having a table for placing thereon a workpiece, and a cutting machine body having a saw blade rotated by an electric motor, there may be caused a phenomenon in which a high frequency current generated in the vicinity of the electric motor is amplified on the side of the table to generate noises to the peripheral devices, and it is an object of the present invention to reduce such noises. It is configured to attach an insulation member (16, 16) to a tilt support shaft (15) that vertically movably supports a cutting machine body (20) relative to the side of a body support section (50) constituted mainly by a table, so that conduction of the high frequency current is blocked.

Description

technical field [0001] The present invention relates to a cutting machine, which is, for example, a stationary circular saw such as a desktop circular saw or a table saw, or a portable circular saw. Background technique [0002] For example, a technology about circular saws is disclosed in the following patent documents. For example, a desktop circular saw has: a workbench, which is used to place the material to be cut; a cutting machine body, which is supported above the workbench and can bob up and down. The cutting machine body has a circular cutting knife that is driven by a motor as a power source. The user can swing the body of the cutting machine downward to make the rotating cutting knife cut into the material to be cut for cutting. [0003] In the above-mentioned cutting machine, the workbench and related components are usually made of metal materials such as steel or non-ferrous metal materials such as aluminum alloy. Wherein, the cutting machine body with the m...
