[Industrial applications]

 The present invention relates to a disposable cutting tool tip that is used for cutting metal and is called a throw-away tip.

[0002]

[Prior art]

 There are various types of cutting tool chips (hereinafter referred to as chips), but each has a plurality of cutting edges. For example, in a chip having a triangular shape in plan view, three corners and three sides of one surface and three corners and three sides of the other surface are cutting edges.

[0003] Thus, this disposable tip should be completely used up and then discarded until at least six corners or six sides of the cutting edge are no longer usable, but in fact left a usable cutting edge. Often discarded as is. This is because the amount of wear of the unusable cutting edge is about 100 to 50 microns, which is very small and cannot be discerned by the naked eye. Even if the cutting edge discolors due to its use, the chips are This is because the change is extremely difficult to see due to dirt and the amount of lighting around.

[0004]

[Problems to be solved by the device]

 Therefore, the purpose of this invention is to provide a tip for a cutting tool that makes it easy for anyone to identify the used cutting edge and completely eliminates waste by completely using all the cutting edges. And

[0005]

[Means for Solving the Problems]

 Explaining the means for solving the above-mentioned problems, the structure is a cutting tool tip having a plurality of cutting blades, and a code for identifying each cutting blade is provided in the vicinity of each cutting blade by unevenness. It is characterized in that it is an attached cutting tool tip.

Further, the present invention is characterized in that the cutting tool chip has a non-use display film formed on each cutting edge portion, which drops off when the cutting blade is used.

[0007]

[Action]

 That is, according to the above configuration, in order to determine the used cutting edge, the code of the used cutting edge is recorded or stored, or the presence or absence of the unused display film is checked to determine whether the used cutting edge has been used. All you have to do is determine the cutting edge.

[0008]

[Effect of device]

 As a result of the above, the effect to be achieved by the present invention will be described. In the cutting tool chip according to claim 1, by recording or storing the sign of the cutting edge used, an unused cutting edge The blades can be easily discriminated regardless of chip dirt and lighting, and all can be used without waste.

Moreover, when the code is attached by engraving or the like during molding of the chip, it never disappears during use unlike printing and the like, and the cutting blade can be fully used.

In the cutting tool tip according to the second aspect, since the reference numerals are arranged so as to correspond to the order of the cutting blades to be used, the cutting blades can be used in order, and unexpected waste is avoided. Therefore, smooth full use can be realized.

In the cutting tool tip according to claim 3, since the order of the cutting blades to be used is indicated by the arrows, the replacement of the cutting blades may be performed sensibly according to the arrows. The effect achieved by the chip for use can be further promoted, and the complete use can be performed more smoothly.

In the cutting tool tip according to claim 4, since the reference numeral is attached to indicate the number of cutting edges of the cutting tool tip, it is indicated how many cutting edges the cutting tool tip to use has. And you can call attention to use until the end.

In the cutting tool tip according to claim 5, since the non-use display film that is removed by abrasion or peeling when used is formed by, for example, plating or coating of metal or synthetic resin, whether the cutting blade is used or not. It can be easily identified by looking at the cutting edge, regardless of chip dirt and lighting.

In the cutting tool tip of the sixth aspect, since the unused display film is formed by depositing a colored synthetic resin different from the background color, the background of different colors is largely exposed by peeling. Therefore, it is extremely easy to determine whether or not it is a used cutting edge.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. (First Embodiment) FIG. 1 is a perspective view showing a disposable cutting tool tip 1 (hereinafter referred to as a tip). This tip 1 is an example of other types of tips, and is shown in FIG. 2, for example. It is held by the holder 11 as described above, and the six corner cutting blades 2 on both upper and lower surfaces are used for cutting metal. Therefore, in the vicinity of each of the three cutting blades 2, ... On the upper and lower sides, reference numerals 3 ... For identifying the cutting blades 2 are attached.

When a side instead of a corner is used as the cutting blade 2, the reference numeral 3 may be attached in the vicinity of the side to be the cutting blade 2 ... Like the chip 1 shown in FIG. When it is necessary to attach a code to both the cutting edges and the edges, it is advisable to change the type of the code and attach each.

The holder 11 described above will be briefly described. In the figure, reference numeral 12 is a clamp screw, and by tightening the clamp screw 12, the lever 13 is attracted and the chip 1 placed on the deposit 14 is attached. Is fixed.

The above-mentioned reference numerals 3 ... May be anything that can identify a certain cutting edge 2, such as “○”, “Δ”, “#”, “*”, but like the numbers shown in the figure. It is preferable that the cutting blades 2 have an order because the signs can be matched to the order of use of the cutting blades 2 ... This is because only the reference numeral 3 of the cutting blade 2 used last needs to be recorded or stored. Further, in this case, if the order of use of the cutting blades 2 is set one by one from one cutting blade 2 on one side as shown in the drawing, the operation of changing the direction of the tip 1 is easy, It is possible to use all cutting blades 2 ...

As the code having the order, in addition to the above-mentioned numbers, for example, letters such as alphabets and kana, and the number of dots such as dice are considered.

Further, the attached positions of the reference numerals 3 ... May be, for example, side surfaces as long as there is no problem in the performance of the cutting blades 2 and the processing of the tip 1.

When attaching the reference numerals 3 ..., the reference numerals for identifying the other cutting blades 2 ... Do not disappear during the cutting operation using one cutting blade 2. If it is one, it may be printed, for example. Even if the reference numeral 3 for identifying the cutting blade 2 in use disappears, there is no problem because it can be determined that the cutting blade 2 is used.

The above-mentioned conditions are required for the attachment of the reference numeral 3 ... However, in reality, if they are formed by marking, they will not be accidentally erased, and the unevenness causes light Is refracted and its code becomes easier to read, which is desirable.

The above-mentioned engraving is carried out at the time of press molding the raw material powder in the manufacturing process of the chip 1. Thereafter, as usual, the coating may be performed by sintering and, if necessary, hardening the surface.

In order to use the tip 1 configured as described above, first, one of the six cutting blades 2 ... Place on 14 and fix. If the cutting edge 2 of "1" becomes unusable due to cutting work, change the direction of the tip 1 and then use the cutting edge 2 of "2". Similarly, the cutting edge 2 of "3" is used, and thereafter, the tip 1 is inverted and the cutting edge 2 of "4" is used. When the cutting blade 2 of "5" and the cutting blade 2 of "6" are used in this order, all the cutting blades 2 of the chip 1 have been used, and the tip 1 is ready to be discarded.

If the cutting work is interrupted or ended in the middle without using the cutting blade 2 of “6”, or the tip 1 is replaced, the cutting blade 2 which has been used or is being used is not used. It suffices to leave the code 3 in the record or the memory. When the cutting operation is restarted, the use may be started from the cutting blade 2 having the reference numeral 3 next to the used cutting blade 2 or the cutting blade 2 in use, based on the above-mentioned recording and memory. .

As described above, since the used cutting blades 2 and the unused cutting blades 2 can be easily discriminated by anyone, the tip 1 should be used completely without waste. You can

Moreover, since the reference numerals 3 ... Correspond to the order of the cutting blades 2 to be used and the order of the cutting blades 2 to be used is set in order from one cutting blade 2, the order is correct. It is possible to use the cutting blades 2 ..., and it is possible to realize smooth full use without unexpected waste.

Further, since the reference numerals 3 ... Are attached by engraving, they never disappear while the chip 1 is in use, and the cutting blades 2 ... Can be fully used.

It should be noted that the above-mentioned reference numerals 3 ... Are not limited to only one type of numeral if they are numbers, but in the case of the diamond 1 in plan view shown in FIG. 4, the reference numeral 3 depends on the cutting angle of the cutting blades 2. You can change the type.

Further, in the case of the small chip 1 as shown in FIG. 5, even if the numeral is a numeral, it is preferable to use Roman numerals as the numerals 3 ... Instead of the arithmetic numeral as described above. This is because there is a low possibility of misunderstanding such as “5” and “6”, and “3” and “8” of arithmetic numbers.

(Second Embodiment) The tip 1 shown in FIG. 6 changes the orientation of the tip 1 when the cutting blades 2 are changed in response to the reference numerals 3 ... It is configured by additionally providing arrows 4 and 5 that indicate the direction in which to perform and arrows 6 and 6 that indicate the time of reversal.

That is, for the reference numerals 3 ... which are arranged counterclockwise such as “1”, “2”, and “3” on the upper surface, the first arrow 4 indicating the opposite clockwise direction and the cutting blades 2 on the upper surface are all used. The second arrows 6 and 6 indicating the time of reversal at the part of the cutting edge 2 of “3” at the time of finishing the reversal, and the third arrow 5 that rotates the chip 1 clockwise after reversal similarly to the above-mentioned first arrow 4. Is attached. Since the second arrows 6 and 6 are formed on the two surfaces formed by the cutting blade 2 of "3", they are prominent regardless of the mounting posture with respect to the boulder 101.

In the chip 1 configured as described above, the order of the cutting blades 2 to be used is displayed with the arrows 4, 5, 6 and 6 shown side by side. , 6, the cutting blades 2 can be used more smoothly.

Third Embodiment The tip 1 shown in FIG. 7 is provided with a reference numeral 7 indicating the number of cutting blades 2 included in the tip 1 in addition to the aforementioned reference numerals 3 ... As shown in the figure, the reference numeral 7 may be the last one of the reference numerals 2 ... That identify the cutting blades 2, .. For example, the reference numeral 7 may be completely different, such as A type, B type, I type, and II type.

In the tip 1 configured as described above, since the reference numeral 7 indicating the number of the cutting blades 2 which the tip 1 has is provided, it is determined how many cutting blades the used tip 1 has. It can be displayed and alerted to use until the end.

(Fourth Embodiment) The chip 1 shown in FIG. 8 has an unused display film 8 formed on each of the six cutting blades 2 ... Where the cutting blades 2 fall off when used for cutting. ing.

The unused display film 8 ... Has heat resistance and is formed by painting, coating, plating or the like using a colored synthetic resin different from the background color, for example, a fluororesin such as Teflon. Put on.

In the chip 1 configured as described above, when the cutting blades 2 are used, the unused display films 8 formed at the positions of the cutting blades 2 fall off. It is extremely easy to determine whether or not. Therefore, it is possible to prevent the usable cutting blades 2 ... from being thrown away while leaving them, and to use the tip 1 completely without waste.
