20090257835 | MULTI-CARTRIDGE CUTTING TOOL AND RAILWAY WHEEL BORING ASSEMBLY - A multi-cartridge cutting tool includes a body with a plurality of cartridge-receiving pockets, and a plurality of insert-receiving cartridges mounted to a respective pocket. A round cutting insert is mounted to each cartridge. The pockets are formed at predetermined distances from a central, longitudinal axis of the body to form a first group and a second group of cutting inserts such that the cutting edges of the first group of cutting inserts and the cutting edges of the second group of cutting inserts are located at different axial and radial distances from the central, longitudinal axis of the body to perform different machining operations. A third group of cutting insert(s) may exist for cutting tools with an odd number of cutting inserts. The different types of machining pockets allow for high feed rates, while greatly improving the life of the cutting insert as compared to conventional cutting tools. A railway wheel boring assembly is also disclosed. | 10-15-2009 |
20090263198 | METAL-CUTTING TOOL - There is provided a metal-cutting tool comprising a tool holder, a replaceable cutting plate, and an adjusting element which is attached by means of screw-fastening means elements and with which the position of the cutting plate on the tool holder can be adjusted. The screw-fastening means comprises a threaded element which interacts with the adjusting element and can be fixed in place in the tool holder. | 10-22-2009 |

20090290944 | CARTRIDGE ASSEMBLY FOR CUTTING TOOL - A cutting tool, such as a slotting cutter, includes a support disc rotatable in a predetermined direction on a central axis. The support disc is of a generally cylindrical shape has a plurality of cartridge-receiving pockets. A cartridge assembly is capable of being mounted to the pocket and includes a cutting insert with at least one cutting edge secured to each cartridge assembly. The cartridge assembly includes a tapered, threaded hole for receiving a tapered, threaded screw. The threaded hole is off-center to divide the lower portion of the cartridge assembly into two portions having different thicknesses and flexibility. A slot extends from the threaded hole to a bottom face of the cartridge assembly. The cartridge assembly expands as the tapered, threaded screw is received in the tapered, threaded hole to secure the cartridge assembly in the pocket. | 11-26-2009 |
20160136740 | NOVEL RIGID UNIVERSAL CARTRIDGE FOR HOLDING SYSTEM - In view of the foregoing, an embodiment herein provides a rigid cartridge for multiple and universal application of all machining processes. The rigid cartridge includes a cylindrical body, a guiding & locating body connected to bottom side of cylindrical body, and a combination screw having a left hand [LH] thread and a right hand [RH] thread, wherein the cylindrical body includes a flat for locking the cartridge with the cutter body by using a locking screw, wherein the combination screw is connected to the bottom end of said guiding & locating body. The LH thread can be provided in cartridge side and RH thread can be provided in cutter body side or vice versa. In the cutter body or boring bar, a slot and/or approach hole can be provided in the cutter body for enabling to rotate the combination screw in clockwise or anti-clockwise direction to move the cartridge in forward and backward direction. | 05-19-2016 |
