Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cutting apparatus for cutting a workpiece such as ceramics.
[0002]
[Prior art]
A cutting apparatus for cutting a workpiece such as ceramics is conventionally provided with a waiting area for a workpiece P such as ceramics by means of loading / unloading means B from inside a cassette C placed in a cassette placement area A as shown in FIG. The workpiece P is carried to the chuck table T by the conveying means E having a swivel arm and held on the chuck table T. After the chuck table T is moved and positioned by the alignment means F, the cutting with the rotating blade is performed. Cutting by means G.
[0003]
As shown in FIG. 5, the chuck table T is rotatably mounted on a moving table 4 that moves along a table guide 3 by a moving means 2 provided in the apparatus main body 1. A water cover 6 is attached to the periphery of the opening 5a, and the water cover 6 is formed to be movable along the edge of the opening 5a.
A drainage hole 5b is provided at an end of the bellows guide / waste liquid tray 5, and a drainage pipe 7 is connected to the drainage hole 5b so that the cutting waste cut by the cutting means G on the chuck table T is a cutting liquid. At the same time, it flows into the drain hole 5 b and is discharged out of the apparatus main body 1 by the drain pipe 7.
A waterproof bellows cover 8 (FIG. 4) is attached to both sides of the water cover 6 to cover the opening 5a and the like to prevent the cutting fluid and the like from entering the apparatus main body 1.
[0004]
[Problems to be solved by the invention]
When a workpiece such as ceramics having a high specific gravity is cut while supplying a cutting fluid, cutting waste having a high specific gravity is clogged in the drain holes 5b and the drain pipe 7, resulting in poor drainage. There was a problem of contaminating the surroundings.
The present invention is made in order to solve such a conventional problem, and provides a cutting device in which the drain hole 5b and the drain pipe 7 are not clogged by cutting waste having a large specific gravity from a workpiece such as ceramics. Is an issue.
[0005]
[Means for Solving the Problems]
As means for technically solving the above-mentioned problem, the present invention provides a cutting table including at least a chuck table for holding a workpiece such as ceramics and a cutting means for cutting the workpiece while supplying a cutting fluid. In the device
The outer periphery of the chuck table is provided with a settling tank for temporarily collecting waste liquid and precipitating cutting waste with a large specific gravity,
The settling tank is a cutting device in which drain holes are formed at intervals in a rising piece on the outer periphery of the bottom,
The sedimentation tank is provided with an engagement hole for fitting the chuck table in the center of the bottom part, an edge piece is formed upward at the peripheral edge part, and a mounting hole is provided at the important part of the bottom part. The gist of the apparatus is as follows.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings (the same members as those in the past are denoted by the same reference numerals).
In FIG. 1, reference numeral 1 denotes an apparatus main body. A cassette C is placed in a cassette placement area A as in the prior art, and a workpiece (not shown) such as ceramics is waiting from inside the cassette C by loading / unloading means B. In addition to being carried out to the region D, it is transported to the chuck table T by the transport means E, moved by the chuck table T and aligned by the alignment means F, and then the workpiece is cut by the cutting means G.
[0007]
The chuck table T is rotatably mounted on the moving table 4 as shown in FIG. 2, and is moved along the table guide 3 by the moving means 2 together with the moving table 4, and a water cover 6 is provided around the chuck table T. It is attached.
[0008]
Reference numeral 9 denotes a settling tank, which is formed in a rectangular tray shape as shown in FIG. 3, and an engagement hole 9a for fitting the chuck table T is provided at the center of the bottom, and an edge piece 9b is directed upward at the peripheral edge thereof. A mounting hole 9c is provided at the bottom portion, and a plurality of drain holes 9e are formed at intervals in the rising piece 9d on the outer periphery.
[0009]
In this settling tank 9, the chuck table T is fitted into the engagement hole 9a and placed on the water cover 6, and the set screw 10 is inserted into the attachment hole 9c and screwed into the screw hole 6a provided in the water cover 6. It is attached by wearing.
[0010]
In the cutting apparatus according to the present invention configured as described above, when a workpiece such as ceramics held on the chuck table T is cut while supplying cutting fluid by the cutting means G, the cutting waste is cut. The cutting waste having a large specific gravity is temporarily stored in the sedimentation tank 9 together with the liquid, and settles and separated at the bottom of the sedimentation tank 9, and the waste liquid is discharged out of the sedimentation tank 9 through the drain hole 9e. The discharged waste liquid flows into the drain pipe 7 through the drain hole 5b and is discharged out of the apparatus main body 1. Although the cutting waste having a small specific gravity is mixed with the waste liquid and discharged, the drain hole 5b and the drain pipe 7 are not clogged.
[0011]
Accordingly, the cutting waste having a large specific gravity does not flow into the drain hole 5b and the drain pipe 7, and the cutting waste becomes clogged as in the conventional case, or the drainage is poor, or the waste liquid leaks out and leaks around the inside of the apparatus main body 1 and the surroundings. It is possible to prevent inconvenience such as contamination. The cutting waste accumulated in the settling tank 9 can be taken out and removed as appropriate.
[0012]
The sedimentation tank may be provided integrally with the water cover. However, as described above, the sedimentation tank is formed separately from the water cover and is detachably attached with a set screw or the like, so that the deposited cutting waste such as ceramics can be removed. It is preferable to facilitate the treatment of the waste liquid containing.
[0013]
【The invention's effect】
As described above, the present invention provides a cutting apparatus including at least a chuck table for holding a workpiece such as ceramics and a cutting means for cutting the workpiece while supplying a cutting fluid. The outer periphery is provided with a settling tank for temporarily collecting waste liquid and precipitating cutting waste with a large specific gravity. The settling tank has drain holes formed at intervals on the rising piece on the outer periphery of the bottom. The settling tank is provided with an engagement hole for fitting the chuck table in the center of the bottom portion, and an edge piece is formed upward at the peripheral portion thereof, and is attached to a key portion of the bottom portion. Since a hole is provided, cutting waste is temporarily stored in the sedimentation tank together with the cutting fluid, cutting waste having a high specific gravity is settled and separated at the bottom, and waste liquid containing cutting waste having a low specific gravity is drained by a drain hole. As appropriate It is. As a result, cutting waste with high specific gravity does not flow into the drain hole and drain pipe, but only waste liquid containing cutting waste with low specific gravity flows into the drain hole and drain pipe. Contamination can be prevented in advance. In particular, since the settling tank is detachably attached to the water cover with a set screw or the like, there is an effect that it is possible to easily treat the remaining waste liquid containing the precipitated cutting waste having a large specific gravity.
