Abstract

The invention relates to an off-resonance elliptical vibration cutting device, and belongs to the technical field of ultra-precision cutting and difficult-to-machine material cutting. A diamond cutter is fixedly connected with a cutter seat on the front portion of a base body through a fastening screw, and the tail ends of two piezoelectric stacks in the X direction are in contact with a lower wedge-shaped block. An upper wedge-shaped block and the lower wedge-shaped block are in contact to constitute a wedge-shaped block pre-tightening mechanism. A wedge-shaped block baffle is fixedly connected with a back plate of the base body through two fastening screws, a wedge-shaped block pre-tightening screw is in threaded connection with the wedge-shaped block baffle and is in butt joint with the upper wedge-shaped block. The free end of each piezoelectric stack is fixedly provided with a stainless steel spherical crown body, and the lower portion of the base body is connected with a wedge-shaped adjusting base through four fastening screws. The off-resonance elliptical vibration cutting device has the advantages that the best cutting performance of difficult-to-machine materials can be acquired, a driving part composed of the piezoelectric stacks and a flexible hinge is more compact in structure, the part, which achieves motion, of the cutter seat is smaller in size, a cutter can still achieve large displacement in the high-frequency cutting process, and the machining efficiency is guaranteed.

Description

Technical field

[0001] The invention belongs to the technical field of ultra-precision cutting and cutting of difficult-to-machine materials, and particularly relates to a non-resonant elliptical vibration cutting device. Background technique

[0002] Single-point diamond cutting is an effective machining method for creating precision and ultra-precision parts, with many advantages that are difficult to surpass. However, the limitation of this method is that the types of workpiece materials that can be cut are limited. Hard and brittle materials such as optical crystals, and ferrous metal materials such as hardened steel are widely used in precision parts and molds. However, these materials will cause problems during the cutting process. Severe diamond tool wear and defects such as cracks and pits on the machined surface are likely to occur. Current cutting methods are difficult to obtain satisfactory surface quality. In order to expand the range of materials that can be cut by ...
