摘要:
Gegenstand der Erfindung ist ein Honwerkzeug zur Feinbearbeitung von Zahnrädern. Erfindungsgemäß ist vorgesehen, dass die Verzahnung (2) quer zur Erstreckungsrichtung der Zähne unterbrochen ist. Die erfindungsgemäße Gestaltung ermöglicht eine ruhige, vibrationsarme Bearbeitung mit einer besseren Kühlmediumzufuhr.
摘要:
A surface treating apparatus for treating an inner surface of a bore containing a shaft may include a body connectable to a drive apparatus and configured to movably receive a shaft extending through a bore, and at least one surface treating member connected to and movable with the body relative to the shaft, the at least one surface treating member sized to be inserted within an annular gap formed between the shaft and an inner surface of the bore and to bear against the inner surface of the bore when the shaft is received by the body.
摘要:
An apparatus, system, and method using an elastic biasing element in combination with an encoder arrangement for precise control of force or torque applied to a moving object, is applied for controlling a feed force applied to an abrasive element of a bore finishing tool, to respond to changes in the feed force such as can arise from contact with a workpiece bore surface and variations therein, such as tapers, hourglass shapes, barrel shapes, and the like. The elastic biasing element can include a single or multiple springs in one or more sets, and the feed force can be selected to have a constant value or vary as a function of time, position, or other variables or conditions.

Disclosed is a drill head for finishing workpieces, a spindle equipped with a drill head of said type, and a method for machining workpieces using a drill head of said type. The drill head includes a solid joint which is actuated by a piezo actuator and on which a tool blade is mounted. According to the invention, the lift of the piezo actuator corresponds to the feeding movement of the tool blade.
摘要:
A tool (1) for mechanochemical treatment comprises a shaft (10), a number n of working ledges (20), n≥1, and a force application arrangement (2). The force application arrangement (2) is configured for applying a working force (F) on the working ledges (20). The working ledges (20) comprises wear-resistant material with a Vickers number above 800 HV and a Young modulus above 200 GPa. Each working ledge (20) has a contact surface (22) facing away from a main axis (11) and having a surface roughness Ra below I μm. The contact surface (22) has a convex curvature which has a radius of curvature that is at most equal to a closest distance from that point to the main axis. A width of the contact surface (22) is less than r/2n. The working force applied on each working ledge (20) is at least P−L−r/2n, where P=107 Pa and L is the contact surface length.
