Abstract
A rotary tool, in particular a high-speed milling or boring tool, has at least two balancing rings (17, 18) with a variable mass around their circumference mounted on the tool holder or tool body (1). Two concentric balancing rings (17, 18) whose position in relation to the axis of rotation (6) of the tool (1) may be adjusted are releasable mounted in the tool holder or in the tool body (1) and are supported in the radial direction (14) in the tool holder or tool body (1). A short rotary tool (1) is thus obtained with a simple support of the balancing rings (17, 18) in the radial direction.
Claims19
A rotary tool, in particular a high-speed milling or boring tool, having at least two balancing rings with a variable mass around their circumference mounted on the tool, the rotary tool having an axis of rotation,
- characterized by the fact that two concentric balancing rings, whose position in relation to each other and in relation to the axis of rotation of the tool may be adjusted, are releasably mounted in the tool and are supported radially adjacent one another.
A rotary tool having an axis of rotation and comprising:
- at least two balancing rings with a variable mass around their circumference, each of the balancing rings being adjustably positioned in relation to each other and in relation to the axis of rotation, and each of the balancing rings being releasably mounted radially adjacent each other in the tool;
- and
- at least one of the balancing rings has a clamping force provided thereto by a clamping member through radially adjustable clamping elements as the clamping member is adjustably positioned in the respective balancing ring.
A rotary tool having an axis of rotation and comprising:
- a tool body for receiving a machine tool, the tool body including an annular groove therein that is substantially radial to the axis of rotation, and the groove including an innermost surface, an outermost surface and a base surface;
- an innermost balancing ring adjustably positioned along the innermost surface and in relation to the axis of rotation;
- and
- an outermost balancing ring adjustably positioned along the outermost surface and in relation to the innermost balancing ring and in relation to the axis rotation, whereby the balancing rings are radially adjacent one another along the axis of rotation.
