Abstract

PURPOSE:To reduce the time required for preparation of working and further process a uniform and high quality cut surface by keeping a supply nozzle for cutting fluid and an attraction inlet for swarf at an optimal position at all times in relation to a cutter tip. CONSTITUTION:A cutter chip 11 is mounted on the tip end of a cutting tool shunk 10, and a supply path for cutting solution and an attraction path 13 for swarf are respectively provided on the side of a rake surface (lower part) 10A and the side of a relief surface 10B. A nozzle part 12a of the tip and an attraction inlet 13a are respectively opened to optimal positions near the cutter chip 11. Hereby, only joint pipes 14, 15 must be detached and attached in replacing the cutting tool to permit the time for preparation of working to be reduced.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a cutting tool for cutting, such as an AJ.

Diamond tool for cutting non-ferrous metal materials such as OXt.

The present invention relates to cutting tools suitable for precision cutting, such as OBN bits for cutting iron-based materials and iron-based materials.

[Background of the invention]

Conventional general cutting tools of this type are shown in Fig. 1.
Tool holding installed on table 5.

Attach tool 3 to stand 4 and install this tool.

A nozzle 1α attached to the tip of a cutting fluid supply pipe 1 and a suction port 2a of a chip suction pipe 2 are provided near both sides of the cutting fluid supply pipe 1, respectively.

The pipe 1 and the chip suction pipe 2 are connected to a magnetic stand 6cL on the table 5 and a magnet on the tool holder 4.

Each is held by a net stand 6b.

There is.

In a cutting tool with such a configuration, when replacing or reinstalling the cutting tool 3, the magnetic stands 6cL, 6
I have to adjust the position of 4.

There was some inconvenience.

In addition, as shown in Fig. 2, the cutting tool described in the catalog of PNETJMO has a suction port 2eL of the chip suction pipe 2 and a cutting fluid supply pipe at the upper and lower parts of the cutting tool 3 attached to the tool holder 4j. It consists of a structure in which one nozzle 1α is provided respectively.

In such a structure, if the holding position of the cutting tool 3 is changed, it is very difficult to set the suction ports 2a and 1a at the optimum positions. By the way.

However, the positions of the nozzle 1α and 1 pump D2α are on the cutting surface.

High-quality cutting has a great effect on the properties of the wood.

To generate the side surface, use the nozzle 1 cL and tll 1 port 2.
tL.

It is important to adjust the position to the optimum position.

Furthermore, when performing fly cutting processing.

The workpiece 7 is placed on a table as shown in FIG.

5 and send this table 5 in direction B.

(from) the tool holder 4 which is rotated in the input direction.

1. Machining the workpiece 7 using the attached cutting tool 3.

conduct. In this case, the table 5 has a nozzle 1α.

Chips having a cutting fluid supply pipe 1 and a suction port 2cL.

Even if the suction tube 2 is installed, the bite 3 is always in the same position.

Because of the change, use 3 bites for the entire cutting surface.

Because it cannot be held in the optimum position, the knee crop 7
It is impossible to obtain a high quality cutting surface over the entire surface of the machine.

[Purpose of the invention]

The present invention solves the problems of the prior art as described above, and allows setup by always keeping the cutting fluid supply nozzle and the chip suction port at the optimum position relative to the cutting tip.

The objective is to provide a cutting tool that can reduce cutting time and provide a uniform, high-quality cutting surface.

That is.

[Summary of the invention]

In order to achieve the above object, the present invention is a part-time job.

In the cutting tool, the cutting tool has a cutting tip attached to the tip of the shank for cutting a workpiece.

Cutting on the rake and flank sides of the shank.

The liquid supply path and the chip suction path are each provided at an angle of 1°, and the nozzle portion at the supply end and the suction port at the end of the suction path are each located near the cutting blade tip by 15140°.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 4 and 5 are a perspective view and a sectional view showing an embodiment of the cutting tool of the present invention.

In the same figure, 10 is a cutting tool shank, a cutting tip 11 is attached to the tip of the cutting tool shank 10, and cutting fluid is installed on the rake surface side (lower part) 10A and the relief surface side (upper part) 10B. A supply path 12 and a chip suction σ1 path 13 are provided, respectively. So.

The nozzle part 12cL at the tip of the cutting fluid supply path 12 and the chips.
The suction ports 13α at the tip of the suction path 13 are opened at optimal positions near the cutting blade tip 11°. 5 On the other hand,
Opposite to the nozzle portion 12a and suction port 13a.

A cutting fluid supply source and a vacuum source (not shown) are provided at each of the four ends of the cutting fluid supply path 12 and the chip suction path 13.

joint pipes 14. .

15 are connected to each other. j1 This embodiment has the structure described above.

When replacing the tool, use a joint pipe of 14.15.

Since it is only necessary to attach and detach the nozzle part 12α.

This is best because the position of the suction port 13cL does not change.

Can be kept in place. 1゜6th
The figure is a perspective view showing an embodiment in which the above-mentioned cutting tool T is applied to fly cutting processing. This embodiment is a joinper for supplying cutting fluid.

The pipe 14 and the joint pipe 15 for sucking chips are connected to the rotary joint 16, and a cutting fluid supply is provided inside each of the support shaft 17 and the tool holding table.

cutting through a channel and a chip suction channel (both not shown).

It is configured to communicate with each passage of the tool T.

In such an embodiment, the cutting fluid supply nozzle (not shown) and the chip suction port 19 provided on the cutting tool T
Since the blade rotates together with the blade, its relative position with the cutting edge is always constant, so the blade rotates over the entire surface of the workpiece 20 placed on the table 21.

Since cutting can be performed under optimal conditions, a uniform, high-quality 1° cutting surface can be achieved.

〔Effect of the invention〕

As explained above, according to the present invention, pie.

Cutting fluid supply nozzle and chip suction installed on the shank.

By always setting the pull mark at the optimum position relative to the cutting tip, there is no need to readjust the positions of the supply nozzle and suction port even when changing the position of the cutting tool or replacing the cutting tool, which makes setup easier. .

This can reduce the amount of time required.

Furthermore, when the cutting tool of the present invention is applied to 7-lie cutting processing, the cutting tool covers the entire surface of the workpiece.

Since it can be cut with the same precision, uniform high quality can be achieved.

It is possible to walk around the cutting surface.
