Abstract: A toolholder includes a cutting tool mounted to a head attached to a collar at a first end of the toolholder. A shank is located at a second, opposite end of the toolholder. A central cavity extends inwardly from the first end toward the shank. A viscous fluid inertia mass damper is disposed within the central cavity. The viscous fluid inertia mass damper includes an absorber body having a first end, a second end opposite the first end, a fluid reservoir formed in the damper body for containing a viscous fluid, and a plurality of apertures formed in the damper body for allowing the viscous fluid to flow from the fluid reservoir and through the apertures to suppress vibration of the toolholder. A method for suppressing vibrations in a toolholder is also disclosed.

Abstract: A rotary cutting tool has a central, longitudinal axis. One or more internal balancing features are disposed within a cavity of the rotary cutting tool. Each internal balancing feature includes a balancing mass suspended within the cavity by a spring-like element, and an adjusting screw for effecting radial movement of the balancing mass. Each internal balancing feature can be integrally-formed with the rotary cutting tool using a 3-D printing technique. The rotary cutting tool can be any rotary cutting tool, such as a milling cutter, a boring bar, and the like. The internal balancing features are arranged at predetermined locations within the rotary cutting tool to enable static and/or dynamic balancing of the rotary cutting tool.

Abstract: A cutting head is formed for insertion into a support in a modular rotary tool, in particular a drill. It has a coupling pin onto which outer cover surfaces and torque surfaces are formed as clamping surfaces. The coupling pin has a particular circular groove, which divides the cutting head into a front pin part and a rear pin part. Stop surfaces for an axial pullout safety are formed in the transition area between the two parts. The torque surfaces and the clamping surfaces are arranged in different pin parts. The torque surfaces are preferably formed in the rear pin part.

Abstract: A tuned or tunable boring tool includes a boring bar defining an elongated cavity therein. A distal end of the boring bar is configured to support a tool or cutting insert. The boring tool further includes a dynamic vibration absorber inserted within the elongated cavity of the boring bar. The dynamic vibration absorber includes a mass that vibrates in conjunction with vibration of the boring bar. The mass has a proximal end and a distal end. The dynamic vibration absorber further includes at least one resilient proximal support positioned adjacent to and supporting the proximal end of the mass and at least one distal resilient support positioned adjacent to and supporting the distal end of the mass. The at least one proximal support and at least one distal support have a different stiffness.

Abstract: A tool holder for carrying a cutting insert wherein the cutting insert is useful for the removal of material during a material removal operation. The tool holder includes a tool holder body. The tool holder body includes a pocket adapted to carry the cutting insert, a coolant inlet in communication with a pressurized source of coolant, a coolant chamber having a central region, an upstream coolant passage having a central longitudinal upstream coolant passage axis, and a downstream coolant passage having a central longitudinal downstream coolant passage axis. The upstream coolant passage opens into the coolant chamber. The upstream coolant passage has an orientation relative to the coolant chamber so that the central longitudinal upstream coolant passage axis is offset from the central region of the coolant chamber whereby coolant flows into the coolant chamber in a tangential fashion.

Abstract: A toolholder includes an absorber mass externally mounted to a body portion of the toolholder. A spacer is disposed within one or more recesses formed in a bottom wall of the absorber mass. One or more resilient members are disposed between the body portion and the absorber mass, and one or more resilient members are disposed between the absorber mass and the spacer. A clamping bolt passes through each spacer, through the absorber mass and is threaded into the body portion of the toolholder. A rigidity of the one or more resilient members can be selectively adjusted by the clamping bolts so as to tune the absorber mass for optimum dampening of vibration of the toolholder.
