2. Description of the Related Art Conventionally, for example, the perforation of a printed circuit board used in a computer or a communication device is due to the nature of the printed circuit board during processing, and the residual oil and water may deteriorate the quality of the finished product. Since it causes a large amount, it is generally performed by dry processing without using cooling oil or the like.

In the case of this dry machining, there is a technique in which a cover (pressure hood) for sucking the discharged machining waste is attached around the machining blade to perform machining while pressing the machining material.

However, when the processing method using this cover is applied to the processing of other metal materials, resins, etc., the above-mentioned cooling oil or the like must be used for cooling the cutting heat generated. .

When processing metal, resin or the like with a machine having this cover, it is necessary to apply a processing agent such as cooling oil, but no countermeasure has been taken.

[0006] However, in some cases, the operator sprays the cooling oil from the outside of the cover body or uses an external device, but this work is performed automatically by the NC processing machine body. However, since the worker must always spray the processing machine with the machine, the objectives of complete automation, labor saving, and labor saving cannot be achieved.

Further, even if the cooling oil is sprayed from the outside of the cover, the cooling oil cannot be directly sprayed on the processing blade or the processing portion.

[0008] In particular, the processing dust generated in the drilling process remains on the surface of the processing material and inside the drilled hole, which causes a large number of troubles and hinders the work in the post process. It had a problem such as.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an article processing apparatus and method according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral A denotes an article processing apparatus, which employs a machine tool having a rotating main spindle. A machining blade is attached to the main spindle, and the article processing apparatus A allows metal, synthetic resin, carbon, Capable of drilling holes in ceramics, wood, stone, glass, etc., end mills, and milling.

The article processing apparatus A is basically composed of the processing blade 1, the cover 2, the jetting means 3, and the discharging means 4. In the present embodiment, the workpiece is processed. Hole b1 for the synthetic resin processing material b which is
A drilling machine that performs the machining will be described.

The machined blade 1 is a drill having a predetermined diameter rotatably supported by a main shaft 5 suspended from the machine body 4, and a table 6 is provided by a feeding means (not shown) provided in the machine body 4.
It is designed so that it can move back and forth with respect to the processing material b placed on it.

The cover 2 is attached to the machine body 4 and surrounds the processing blade 1 and the processing portion so that a predetermined processing space 7 is formed.
It is possible to prevent the scattering of the processing waste of the processing material b due to the above, and the diffusion of the processing agent 3a by the jetting means 3 described later.

The upper part of the cover 2 is a body 4
It is inserted in a vertically movable column 8 so as to be able to move up and down, and is mounted so as to be normally urged downward by a fluid cylinder such as air or a bullet 9 such as a spring.

Further, the lower side of the cover 2 is formed in a funnel shape and is squeezed so that it can surround the vicinity of the processed portion of the processing material b, and the lower side is opened. At the same time, it has flatness so as to uniformly contact the upper surface of the processing material b and obtain airtightness at the time of contact.

Therefore, the processing space 7 for the processing blade 1
Is in a state of being cut off from the outside of the processing (outer peripheral portion).

It should be noted that this lower side portion does not necessarily have to come into contact with the processing material b during processing, and it is also possible to cope with a close state.

The above-mentioned jetting means 3 is provided in the cover 2 so that its discharge hole 10 faces the inside of the cover 2 and jets out the processing agent 3a.
Is connected to the discharge hole 10.

The processing agent 3a is for suppressing heat generation and cutting resistance generated when drilling the processing material b.
The type is appropriately selected according to the properties of the processing material b such as water, cooling oil, or air, and the ejection from the discharge hole 10 is preferably in the form of a mist in terms of efficiency. Further, as the processing agent 3a, those encapsulated in microcapsules can be used, and the processing agent 3a is ruptured when it collides with the jetting pressure or the processing blade 1 and the workpiece b, and the processing agent 3a is exposed to a predetermined extent. It may be one that exerts an effect.

The processing agent 3a can be jetted in a liquid state, a bubble state, or a granular state other than the mist state.

Further, the discharge holes 10 are provided at one place or a plurality of places in the cover body 2, and as shown in FIG. 1, they are jetted toward the processing portion of the processing blade 1 and the workpiece b. Or, although not shown,
On the inner peripheral surface of the cover 2 excluding the suction holes, which will be described later, a large number of them are provided at predetermined intervals, or the injection angles thereof are different.

Further, the injection time and injection amount of the processing agent 3a are
It is appropriately controlled by a control means (not shown) depending on the processing state and the member to be processed, and continuous or intermittent ejection is performed.

The discharging means 4 described above is provided on the cover body 2,
It is for sucking the processing dust with the suction hole 12 facing the inside of the cover 2 and the sprayed processing agent 3a. The suction hole 12 is a dust collector provided with a blower or a filter having a predetermined suction force 13 is connected, the used processing agent 3a is separated in a predetermined manner, and the usable processing agent 3a is the injection device 1
It is returned to the No. 1 tank and recycled.

Further, the suction holes 12 are provided at one or a plurality of locations on the inner peripheral portion of the cover body 2, and the attachment position thereof can be an arbitrary position such as an upper portion, an intermediate portion or a lower portion of the cover body 2. It is also possible to form a ring,
It is opened so as to be in harmony with the discharge hole 12 described above.

In the embodiment of the present invention constructed as described above, the drill 1 is fixed to the main shaft 5 of the drilling machine, the drill 1 is rotated at a predetermined speed, and the injection means 3 and the discharge means 4 are operated. Then, when the machine body 4 is lowered toward the processing material b, the cover 2 attached to the machine body 4 comes into contact with the upper surface of the processing material b, and when the machine body 4 is further lowered,
The cover 2 holds the processing material b with a predetermined pressing force by the bullet 9 and a predetermined processing space 7 is formed around the drill 1 by the cover 2.

In this state, if the drill 1 is fed out by the feeding means and stuck to the processing material b, the drill 1 is made a predetermined hole b1 by its rotation and feeding.

At this time, the processing agent 3a is ejected from the discharge hole 10 of the cover 2, and the processing agent 3a is used for the drill 1.
Since it is sprayed in the form of mist on the machining site on the surface of the machining material, or on the hole b1 in the middle of drilling, the cutting resistance by the drill 1 is reduced and the heat generated by cutting is suppressed.
The hole is smoothly and favorably drilled, and the outer edge of the hole b1 is free from corner drops, burrs, and the like.

Further, deeper hole drilling can be performed as compared with the case where this device is not used.

Further, by simultaneously operating the discharging means 4 provided on the cover 2, the scraps scraped off by the drill 1 and the used processing agent 3a are forcibly sucked from the suction holes 12 and can be used in the dust collector 13. The processing agent 3a is collected,
It is returned to the tank of the injection device 11.

Therefore, the discharging means 4 prevents the processing agent 3a and the processing waste from remaining on the surface of the processed processing material b, the inside of the perforation b1, or the vicinity thereof. It should be noted that, when a hole is drilled in the processing material b, step processing is performed in which the spindle 5 is moved up and down, so that the processing agent 3
Penetration of a into the hole b1 is improved, and the cutting dust discharging effect is promoted.

[0038]

According to the present invention configured as described above, in the predetermined processing of the member to be processed by the processing blade, the processing and the supply of the processing agent at the time of the processing are performed in the cover body surrounding the processing blade. Since it is carried out, the processing waste and the processing agent are all collected without scattering to the outside, and clean processing can be performed.

Since the working agent can be directly applied to the working blade or the member to be processed, high cooling efficiency and lubrication efficiency can be obtained, and a high quality working member can be processed.

Since the processing agent is jetted out within the narrow volume of the cover, the processing agent does not scatter and the processing agent spreads instantly and evenly in this processing space, so that a small amount of processing agent can be used. In addition, it is economical with no waste, and the supply and recovery device of this processing agent is downsized.

Cooling, lubrication and the like are performed by injecting the processing agent onto the member to be processed, so that the processing speed can be made faster than before, the processing time can be greatly shortened, and the processing efficiency can be increased. . It has unique effects such as.
