| 20110020072 | SHIM FOR A CUTTING INSERT AND CUTTING INSERT-SHIM ASSEMBLY WITH INTERNAL COOLANT DELIVERY - A cutting insert-shim assembly that has a cutting insert with a bottom surface and a plurality of interior coolant passages wherein each interior coolant passage has a coolant inlet in the bottom surface of the cutting insert. The shim has a first side surface and a second side surface and contains a cavity, which communicates with the coolant conduit. The cavity defines a first opening in the first side surface and a second opening in the second side surface. When the shim is in a first condition, the first side surface contacts the bottom surface of the cutting insert and the first opening provides a first level of coolant communication to the interior coolant passages in the cutting insert. When the shim is in a second condition, the second side surface contacts the bottom surface of the cutting insert and the second opening provides a second level of coolant communication to the interior coolant passages in the cutting insert. | 01-27-2011 |
| 20110020073 | CUTTING INSERT ASSEMBLY AND COMPONENTS THEREOF - A cutting assembly that is useful in an operation for chipforming removal of material from a workpiece. The cutting assembly includes a holder having a seat and containing a coolant delivery passage. A locking pin, which has a longitudinal locking pin bore, is affixed to the seat so the longitudinal locking pin bore is in communication with the coolant delivery passage. A cutting insert has a rake surface, a corner cutting edge region, a central cutting insert aperture, and a radial coolant trough with an orientation toward the corner cutting edge region. At least a portion of the locking pin is within the central cutting insert aperture. A clamp assembly attaches to the holder and engages the cutting insert. The clamp assembly has a diverter plate, which has a bottom surface defining a diverter bowl and a diverter channel. The longitudinal locking pin bore opening to the diverter plate whereby coolant flows into the diverter bowl and through the diverter channel into the radial coolant trough toward the corner cutting edge region. | 01-27-2011 |
| 20110020075 | METAL CUTTING SYSTEM FOR EFFECTIVE COOLANT DELIVERY - A metal cutting system with a tool holder, a shim, an insert with a top depression, a top piece and a clamp. A rake face cooling channel for fluid delivery is formed between the top piece and the depression in the insert. A primary discharge slot at the end of the rake face cooling channel delivers fluid from below the cutting edge of the insert. A second cooling channel for delivery of fluid to the flank face is formed between the insert and the shim or is formed between the shim and the tool holder with a portion of the cooling channel passing through the shim. | 01-27-2011 |
| 20110020076 | METAL CUTTING SYSTEM FOR EFFECTIVE COOLANT DELIVERY - A metal cutting system with a tool holder, a shim, an insert with a top depression, a top piece and a clamp. A rake face cooling channel for fluid delivery is formed between the top piece and the depression in the insert. A primary discharge slot at the end of the rake face cooling channel delivers fluid from below the cutting edge of the insert. A second cooling channel for delivery of fluid to the flank face is formed between the insert and the shim or is formed between the shim and the tool holder with a portion of the cooling channel passing through the shim. | 01-27-2011 |

A rake face cooling channel for fluid delivery is formed between the top piece and the depression in the insert. A primary discharge slot at the end of the rake face cooling channel delivers fluid from below the cutting edge of the insert. A second cooling channel for delivery of fluid to the flank face is formed between the insert and the shim or is formed between the shim and the tool holder with a portion of the cooling channel passing through the shim. | 02-03-2011 |
| 20110027023 | MILLING CUTTER AND MILLING INSERT WITH COOLANT DELIVERY - A cutting insert for use in chipforming and material removal from a workpiece wherein coolant is supplied to the cutting insert from a coolant source. The cutting insert includes at least one discrete cutting location and at least one distinct internal channel that corresponds to the cutting location. The internal channel has an inlet to receive coolant and an outlet to exit coolant. The outlet is proximate to the cutting location, and the inlet is radial inward of the outlet. | 02-03-2011 |
