摘要： A cutting part (1) for a tool head (2) for a lathe (3) for machining a workpiece (4), having a cutting edge (5) for removing material from the workpiece (4) and having a rake face (6) for guiding away the removed material or cuttings. The problem of providing a cutting part (1) which can be realized in a simple manner and with which lead-free materials can also be machined is solved in that a flat structure (7) is formed in the rake face (6) of the cutting part (1) adjoining the cutting edge (5) for breaking the cuttings. A lathe (3) for machining a workpiece (4), having a tool head (2) is provided with at least one such cutting part (1).

摘要： A damper system for a cutting tool is provided having at least one damper body that is added to a cutter body of the cutting tool to help dampen a vibration when the cutting tool is placed in use. The damper body is supported by a damper ring. The damper ring is held in place between a central support boss or hub and an adjustable top cap. The adjustable top cap can be tightened or loosened by use of a fastener element to change the amount of pressure on the damper ring. By adjusting the tension placed on the damper ring, the damper system can be tuned to better suppress vibrations when the cutting tool is placed in use.

摘要： Cutting tool holders are disclosed that include vibration dampening elements. The vibration dampening elements may extend parallel to a longitudinal plane of the cutting tool holder. The vibration dampening elements allow the cutting tool holders to have a smaller width while still providing higher grooving depth.

摘要： A method for deburring an internally toothed workpiece includes providing a workpiece and a deburring tool. The workpiece has an inner toothing produced by hob peeling, with first and second tooth flanks. The deburring tool has a first cutting plate and a second cutting plate, diametrically opposed to the first cutting plate. The method includes rotating the workpiece in a first rotating direction and deburring the first tooth flanks with the first cutting plate while the deburring tool is not rotating. The method also includes shifting the deburring tool relative to the workpiece such that the first cutting plate and the second cutting plate do not contact the workpiece, rotating the workpiece in a second rotating direction, opposite the first rotating direction, further shifting the deburring tool relative to the workpiece, and deburring the second tooth flanks with the second cutting plate while the deburring tool is not rotating.
