摘要:
A machine for determining dynamically a residual unbalance in a workpiece having a conical surface is provided with a plurality of support elements, such as roller elements, that communicate with the workpiece at the conical surface thereof. The roller elements are arranged circumferentially equidistant about the workpiece and may have cylindrical or conical configurations. Further support elements, such as roller elements, can be applied against an annular surface of the workpiece, such as on a flange portion thereof. At least one of the support rollers that communicates with the conical surface is arranged to rotate about an adjustable axis of rotation that can be oriented with respect to the workpiece to achieve good rotative communication therebetween. The rollers are arranged to rotate at different speeds from the workpiece, whereby an unbalance signal associated with the workpiece can readily be isolated from a composite signal having unbalance information related to a residual unbalance of the workpiece combined with residual unbalances of the rollers.

The invention relates to a cutter head having a substantially cylindrical main body and a plurality of replaceably cutting elements disposed at the periphery of said main body and having at least one cutting edge in the axial and/or radial direction of said main body. For achieving a reliable three-dimensional adjustment of the cutting members within extremely close tolerances, each cutting member is mounted on a carrier member itself mounted on said main body and adapted to be radially and axially adjusted relative to the main body by means of separate adjustment means disposed between said main body and said carrier member, and to be fixed relative to said main body with the aid of clamping means.
摘要:
A numerically controlled machine tool with optimum adaptive control mechanism capable of properly altering the cutting section area and stopping of the cutting operation by selfcorrection of the commands from pre-arranged reference program upon detection of a signal indicating a cutting force exceeding the reference limits and representing an abnormal pocket pressure and being derived as an electric output from a mechano-electric transducer during continuous checking of the pocket pressures of a hydrostatic bearing which support the cutting force being applied to the cutting tool throughout its cutting operation.
