Problems solved by technology

However, the disadvantage of this method is that CAD model compensation of the insert may still be required to obtain the desired inclination of the lower surface of the insert, and this compensation may be difficult to perform correctly because different cemented carbide powder grades act differently during sintering. effect, and thus may require different compensating
Moreover, the contact between the blade and the bottom surface of the sipe is obtained in a restricted area of ​​the blade, thereby having a negative impact on the stability of the blade in the sipe and on the durability and life of the blade

Embodiment Construction

[0042] exist figure 1 A milling tool 1 according to an embodiment of the invention is shown in . The tool comprises a tool body 2 having six seats or pockets 3 each receiving a double-sided cutting insert 4 releasably secured thereto. The tool body 2 comprises a front end 5 and a rear end 6 between which a central axis of rotation C1 extends, about which the tool is rotatable in a direction of rotation R. The sipe 3 is formed in the transition between the front end and an envelope surface 7 extending between the front end and the rear end of the tool body.

[0043] figure 2 A cutting insert 4 is shown that is included in the milling tool and is double-sided or reversible, meaning that its top and bottom have the same design, but are shown as upper sided in the case of the orientation of the insert in the figure That side will hereinafter be referred to as the top, although it may just as well be the bottom or underside of the blade. Accordingly, as seen in this figure, th...

Abstract

A tool body (2) of a cutting tool comprising at least one insert sipe (3) having a bottom surface with a support surface configured to treat Support is provided by the lower surface of the insert (4) received in this sipe and having at least one cutting edge (11) formed on the top surface and connecting the lower surface and the top surface Surfaces are connected between the side surfaces. The bottom surface of the sipe has a counterbore central portion (15) surrounded by a peripheral bottom surface portion (16) configured to form the The bottom surface is the sole support surface of the lower surface of the insert to be received in the sipe.

Description

technical field [0001] The invention relates to a cutting tool comprising a tool body and at least one cutting insert, a tool body for such a cutting tool and a method for producing such a tool body. [0002] The invention relates in particular to cutting tools for milling and for this reason will be mainly discussed and shown below for this particular application, but the invention is not at all restricted thereto. The tool can also be used only for other types of chip-removing machining, such as turning or drilling. Examples of conceivable milling processes are face milling, profile milling, shoulder milling, trimming and interpolation. [0003] Such milling tools typically have a plurality (eg, six) of flutes to which cutting inserts are releasably secured for enabling indexing of the cutting inserts to change the cutting edge for chip removal machining. It is extremely important for the result of the machining and the life of the cutting insert that the insert received i...
