Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cutting device for cutting, for example, stone materials.

(Prior Art) Conventionally, as a cutting device of this kind of stone material, as shown in FIG. 10, columns 81 and 82 are erected correspondingly on a base 80, and both columns 81 and 82 are provided. A guide rail 84 is horizontally installed between the slide boxes 83 that are vertically movable in the
The slide box 83 is provided with an elevating device installed in the columns 81 and 82, for example, a female screw (not shown) that is screwed into a screw rod that is rotated by a motor 85 is interlocked, and the guide rail 84 is horizontally moved by the rotation of the screw rod. The guide rail 84 has a cutter
The 85 is mounted so as to be movable in the horizontal direction. The moving body 86 of the cutter portion 85 has sliding surfaces 84a, 84b of the guide rail 84.

A cutter driving motor 88 is mounted on the cutter shaft 89, and a cutter shaft 89 is rotatably supported in a lower portion of the moving body 86 in a direction orthogonal to the guide rail 84. One end side of the cutter shaft 89 is, for example, a belt device or the like. Is connected to the drive motor 88 by
A cutter 90 is detachably attached to the other end of the cutter shaft 89. The cutter portion 85 thus provided is moved along the guide rail 84 by pushing and pulling the manual handle 91 attached to the moving body 86.

(Problem to be solved) However, in this conventional cutting device, since the cutter portion 85 is moved along the guide rail 84 via the moving body 86, in the cutting process of the stone material, the cutter 90 is used.
It cuts while pouring water to the cutting part by the water injection device 92, but since the rotation speed of the cutter 90 is high, the cutter part
Although the cover 93 is attached to the 85, the vertical scatters in the state of containing cutting chips, and these are attached to the sliding surfaces 84a and 84b of the guide rail 84 to form cutting chips. During the movement of the sliding body 86, it adheres to the rotator 87 and penetrates into the bearing portion of the sliding body 86, causing wear and backlash, and the sliding surfaces 84a and 84b of the guide rail 84 also wear and cutting by the cutter 90. There was a problem that the accuracy of the surface went wrong and maintenance was time-consuming.
