Problems solved by technology

[0004] However, in the wire saw of the fixed abrasive method, when the wire is repeatedly wound up and sent out by the reel, the fixed abrasive wire wound on the reel rubs against each other, and the abrasive grains or the bare wire of the wire are worn away. become a problem

no. 1 approach

[0063] Hereinafter, 1st Embodiment which actualized the wire saw is demonstrated.

[0064] Such as figure 1 As shown, the wire saw includes: a first wire reel 11 for storing unused wire 10 ; and a second wire reel 12 for recovering the used wire 10 . One end of the wire 10 is fixed to the first reel 11 , and the other end of the wire 10 is fixed to the second reel 12 . The first bobbin 11 and the second bobbin 12 are rotatably supported by a frame (not shown) at a distance from each other. An output shaft 17 of a reel motor 13 capable of forward and reverse rotation is connected to the first spool 11 via a power transmission mechanism 14 . An output shaft 18 of a spool motor 15 capable of forward and reverse rotation is connected to the second spool 12 via a power transmission mechanism 16 . The power transmission mechanisms 14 and 16 are clutches such as friction clutches and electromagnetic clutches.

[0065] In addition, between the first bobbin 11 and the second bobbin...

no. 2 approach

[0109] Next, refer to Figure 14 ~ Figure 24 , the second embodiment of the wire saw will be described focusing on the points of difference from the first embodiment. In addition, the basic structure of the wire saw of this embodiment is the same as that of 1st Embodiment, and redundant description is abbreviate|omitted.

[0110] Such as Figure 14 As shown, in the initial state of starting the preparation process, the second spool 12 has the cover 62 detachably attached to the spool body 50 , and the spool body 40 of the first spool 11 has no cover attached. In addition, when the preparatory process is completed, the cover 61 having the same structure as the cover 62 of the second spool 12 is also attached to the first spool 11 .

[0111] The output shaft 17 of the spool motor 13 is connected to the spool body 40 of the first spool 11 . Moreover, the output shaft 18 of the motor 15 for spools is connected to the spool main body 50 of the 2nd spool 12. As shown in FIG. In ...

Abstract

In a wire saw, an object to be processed is pressed against a wire (10), whereby the object to be processed is cut. This wire saw is provided with a first bobbin (11) having a wire reel surface on which the wire (10) is reeled before the wire (10) is used in cutting, a second bobbin (12) having a wire reel surface on which the wire recovered from the first bobbin (11) is reeled, and a rotation control unit (60) for controlling the rotation of the first bobbin (11) and the rotation of the second bobbin (12). The first bobbin (11) and / or the second bobbin (12) includes a bobbin body (40, 50) to which the wire reel surface is provided, and a cover (42, 52) to which is provided a cylindrical winding surface that surrounds the wire reel surface. The first bobbin (11) and the second bobbin (12) are controlled such that when the wire (10) moves in a reciprocating manner therebetween, the wire (10) is wound on the winding surface.

Description

technical field [0001] The present invention relates to a wire saw using a wire having abrasive grains fixed to the surface of the bare wire. Background technique [0002] The wire saw alternately repeats the operation of winding the wire sent out from the first reel with the second reel and the operation of winding the wire sent out from the second reel with the first reel , by pushing the workpiece to the wire, the workpiece is cut. [0003] A free abrasive wire saw supplies a slurry containing abrasive grains and a cutting fluid to a wire to cut a workpiece. On the other hand, the wire saw of the fixed abrasive method cuts the workpiece by using the fixed abrasive wire rod with abrasive grains such as diamond adhered to the surface of the bare wire, so it is more efficient than the wire saw of the free abrasive method. It is advantageous in terms of increasing the wire speed of the wire rod. [0004] However, in the wire saw of the fixed abrasive method, when the wire ...
