Abstract
A cutting tool includes a holder and at lest two first cutting inserts. The holder has a number of insert pockets in order to receive those cutting inserts. The cutting inserts are mounted in the holder such that their radially outermost portions lie substantially in an imaginary circle. The circle constitutes an effective diameter of the cutting tool. The cutting tool, in addition, includes at least one second cutting insert provided for a machining operation different from that of the first cutting inserts. The second cutting insert is spaced radially inwardly from the circle.
Claims14
Cutting tool for chip removing machining, comprising:
- a holder defining a center axis and having a plurality of insert pockets formed therein;
- at least two first cutting inserts mounted in respective ones of the pockets and configured for performing a first type of machining operation, wherein radially outermost portions of the first cutting inserts lie substantially on an imaginary circle;
- and
- at least one second cutting insert mounted on the holder and configured for performing a second type of machining operation different from the first type, the at least one second cutting insert spaced radially inwardly from the imaginary circle.
A holder for a chip removing machining tool, comprising a body defining a center axis and having a plurality of first insert pockets positioned such that radially outermost portions of the first insert pockets lie on an imaginary circle, and at least one second pocket spaced radially inside of the imaginary circle.
A holder for a chip removing machining tool, comprising a body having a center axis and a through-hole formed therethrough along the center axis, the through-hole defining an inner periphery of the holder, a first plurality of insert pockets formed around an outer periphery of the holder, and a second plurality of insert pockets formed around the inner periphery of the holder.
A method of machining a workpiece comprising the steps of:
- A) positioning, adjacent the workpiece, a cutting tool comprising a holder defining a center axis and having a plurality of first cutting inserts and at least one second cutting insert disposed thereon, the first cutting insert being configured differently from the at least one second cutting insert;
- B) performing a first chip forming machining operation on the workpiece by the first cutting inserts, while the at least one second cutting insert remains passive;
- and
- C) performing a different chip-forming machining operation on the workpiece by the at least one second cutting insert while the first cutting inserts remain passive.
