<P>PROBLEM TO BE SOLVED: To provide an indexable milling insert and a corresponding basic body, intended for use in milling tools of small diameters, foremost in rotary shank-end mills for the machining of metallic workpieces, and also to provide a milling tool having indexable milling inserts detachably mounted in a basic body. <P>SOLUTION: The milling insert is mounted in the basic body without fastening members, which considerably facilitates the mounting of the milling inserts for an operator who should handle the milling tool. An interface is created between the milling inserts and the basic body, which guarantees that the milling insert is kept in place at the correct position during the milling operation, without a fastening member needing to be used. The milling insert is fitted tangentially obliquely down into the body from the side by means of a key and is locked in all directions using a lock means of the milling insert and the basic body, respectively. The lock means consists of locking surfaces and coupling means, and the interface created by the lock means provides the milling insert a satisfactory stability. <P>COPYRIGHT: (C)2012,JPO&INPIT |
