Abstract

PURPOSE:To prevent a cutting edge from breaking and perform good cutting, by setting a cutting edge flank angle to a positive degree of 20 deg. or more further applying chamfer honing at a degree of the flank angle or more to an edge point of the cutting edge. CONSTITUTION:A cutting edge 5, being constituted by a main cutting edge 5a and a subcutting edge 5b, sets a flank angle TN of a flank 4 for the main cutting edge 5a to a 20 deg. positive angle. Also the subcutting edge 5b is given a flank angle TN1 of 25 deg. positive angle. A crossing part of a rake face 2 with the flank 4 applies a chamfer honing 6, and a honing angle H is set to 20 deg. or more. Accordingly, a throw away tip, excellent in its wearing resistance, is obtained by reinforcing strength of the cutting edge and enabling an easily breaking disadvantage of ceramic to be covered.

In order to shorten the machining time, increasing the machining speed,
It is essential to extend the life of cutting tools used in machining, and of course, indexable tips used in cutting tools are also required to have higher machining speed and longer life. , a ceramic indexable tip has been produced and is attracting attention.

``Problems to be Solved by the Invention'' However, conventional indexable ceramic inserts have the problem of being prone to chipping and breakage of the cutting edge, even though they are negative inserts. To prevent this problem, the thickness of the tip should be increased to about 1.5 times that when using cemented carbide, or the use should be limited to bit use, or the cutting conditions should be limited to finishing use. countermeasures were necessary.

This invention was made to solve the problem of multiple connections,
This overcomes the disadvantage of ceramics, which is that they easily chip, and therefore there is no need to increase the thickness of the insert or limit the application or cutting conditions, making it possible to maximize the characteristics of ceramics' excellent wear resistance. The purpose is to provide ceramic indexable tips.

``Process that led to the invention'' With negative inserts, the rake angle of the insert is set to a negative value, so the friction with the chips during cutting is large, and as a result, the cutting resistance becomes large. There is a disadvantage that a large amount of cutting heat is easily generated, and the cutting edge portion of the chip is easily softened by this cutting heat.

The applicant presumed that the main cause of problems such as chipping and chipping in conventional ceramic throw-away depths was due to the drawbacks of the negative tip itself, and developed ceramics with a clearance angle of about 10 degrees. A cutting test was conducted using a positive tip manufactured by the company. However, the expected effects were hardly achieved.

As a result, since the strength of the cutting edge was low, chipping occurred at an early stage and the chipping progressed to chipping, so that the cutting edge was hardly usable.

However, it has been found that even in cases where the relief angle is 20 degrees or more, such as in the case of a double chain, if the cutting edge portion is honed, chipping due to a decrease in the strength of the cutting edge and resulting damage can be prevented. Moreover, the rake angle is 1
You can set it to a relatively large value, such as setting it to 0 degrees, so
Cutting heat and cutting resistance were significantly reduced, allowing for good cutting.

``Action'' With this configuration, as mentioned in Moe's ``Process leading to the invention,'' the rake angle of the cutting edge can be set to 1 square.
You can set it to a relatively large value, such as setting it to 0 degrees, so
Cutting heat and cutting resistance can be significantly reduced, and the strength of the cutting edge can be reinforced by chamfer honing. Therefore, the drawback of ceramics being easy to chip can be overcome without taking measures such as increasing the thickness of the depth or restricting the application or cutting conditions.
This makes it possible to make the most of ceramic's excellent wear resistance.

This indexable tip 1 is attached to a indexable cutter for face milling, as shown in Fig. 1 (A).
As shown in FIG. 2, it is formed into a flat plate having a substantially square shape when viewed from above, and its upper surface is set as the <0 surface 2, and its lower surface is used as a mounting surface 3 for mounting on a chip seat. The side surface existing between the rake surface 2 and the mounting surface 3 is used as a relief surface 4, and a cutting edge 5 is formed at the intersection of this relief surface 4 and the rake surface 2.

Since the tip 1 is used for face milling, the cutting edge 5 is composed of a main cutting edge 5a and a sub-cutting edge 5b, and the clearance angle TN of the clearance surface 4 with respect to the main cutting edge 5a is the first. As shown in Figure (B), the angle is set to 20 degrees, and the secondary cutting edge 5b is also set to a square angle of 20 degrees as shown in Figure 1 (C).
A clearance angle TN of 5 degrees is given.

Further, the cutting edges of the cutting edges 5a and 5b, that is, the intersection of the rake face 2 and the flank face 4, are chamfer honed 6 as shown in FIG. The width α of this chamfer honing 6 along the rake face 2 is 0.
The honing angle I] is set to be approximately 1 mm to 0.2 mm, and the honing angle I] is set to 20 degrees or more in accordance with the clearance angle 1''N of the main cutting edge 5a.

The honing width α was set as 0.1 as described above.
This is because if it is smaller than 0.2 mm, the strength of the cutting edge portion cannot be sufficiently improved, while if it is larger than 0.2 mm, the increase in cutting resistance cannot be ignored. Further, the reason why the honing angle H is set as described above is to set the rake angle of the honing 6 to around -10 degrees when it is attached to a cutter body 7, which will be described later.

In order to confirm the effect of the above embodiment, the cutter body 7
was attached to a face milling cutter and a cutting test was conducted, and the results were good.
No chipping or damage occurred. When used for face milling in this way, cutting becomes interrupted cutting,
The operating conditions are more severe than those used for conventional cutting tools and finishing tools, and the fact that good results were obtained under these conditions is highly commendable.

Regarding the above-mentioned ceramic indexable tip 1, if round honing is applied to the tip 6a (see Fig. 2) after chamfer honing 6, chipping will be less likely to occur and the effect will be even more effective. can be increased.

Further, in the above embodiment, the sheet member 8 can be omitted by providing a flat hard sheet member 8, as shown in FIG. However, according to the results of the cutting test, the use of the sheet member 8 seemed to be more effective in preventing chipping and chipping.

この場合の理由としては、次、のように考察した。The reasons for this case were considered as follows.

In other words, chipping is caused by high vibration of the cutter body 7 or the workpiece. It is thought that the chipping occurs due to the development of a small crack due to -C cutting edge cracking, ttrg stiffness, and chipping, but the flatness and hardness of the chip seat 7a have a large influence on the chatter vibration. Therefore, by interposing the flat sheet member 8 as described above, the effect of mitigating the chatter vibration itself is produced, and the effect of preventing chipping and chipping may be improved.

Further, the inclination angle of each surface of the chip seat 7a is preferably set according to the relief angle TN-TN of the chip l, etc.
For example, if the surface clearance angle TN is larger than that in the example, it is preferable to increase the true rake angle T accordingly, and the clearance angle ON of the chip l's clearance angle 4 is It is preferable to minimize it to the extent possible in order to prevent damage.

"Effects of the Invention" As is clear from the above explanation, the ceramic indexable insert of the present invention has a cutting edge clearance angle set to a positive angle of 20 degrees or more, and a surface marking on the cutting edge of the cutting edge. With a configuration in which chamfer honing is performed at an angle greater than the relief angle, the rake angle of the cutting edge can be set to a relatively large value, such as a square 10 degrees, which significantly reduces cutting heat and cutting resistance. Furthermore, the strength of the cutting edge can be reinforced by chamfer honing. Therefore, it is possible to overcome the disadvantage of ceramics, which is that they are easily chipped, and to maximize the excellent wear resistance properties of ceramics without having to take measures such as increasing the thickness of the insert or restricting the application or cutting conditions. It will be possible to pull it out.
