20Khz ultrasonic vibration milling transducer for metal cutting

Introduction:

Classical technologies of ultrasonic material processing allow one to obtain surface and subsurface nanostructures, but only auto-resonant technologies can ensure the stability of structuring and obtaining the desired properties of the surface and nanocrystalline structures with certain parameters.
Obtaining of specific and highly efficient (in terms of physical and mechanical properties) nanocrystalline structures at auto-resonant ultrasonic cutting steel copper and brass points to the importance of learning and developing of a method of ultrasonic cutting and smoothing of materials.

A number of other industrial auto-resonant ultrasonic devices have been elaborated.
• Pecialized equipment for surface hardening of work-pieces to improve the surface finish and
to harden the surface layer of the material.
• Wire drawing device to manufacture such delicate wires as thin filaments of precious metals.
• Ultrasonic apparatus for dimensional processing of holes and cavities of arbitrary shape in
brittle materials.
In parallel with the industrial auto-resonant ultrasonic equipment we also propose household
devices.
• Putty knife: intended for surface plastering and filling; eliminates putty sticking to the
instrument; allows obtaining thin layers of putty; provides its better adhesion to the working
surface. A similar device can be used to apply creams with cosmetic and medicinal purposes.
• Knife: intended for cutting products prone to crumpling, squashing and sticking (fresh bread,
cheese, cakes, etc.).
• Chisel: designed for wood carving and channeling in wood products, for example, sockets for
mortise locks.
• Kreytsmeysel: intended for cutting metal, for example, for engraving on metallic surfaces or
making moulds for precious metal jewelry.
• Blade sharpening device for knives and scalpels: sharpens blades simultaneously with
hardening of the material by plastic deformation (whetting) of the blades. It can be used, for
example, for whetting the scythe blades.
This list can be greatly extended, first of all, due to various vibration technological machines
operating in sub-ultrasound-frequency bands

The devices designed for turning enable one to perform the following:
1. Significantly reduce the cutting force;
2. Handle technologically nonrigid products not using supporting lunettes;
3. Create reinforced near-surface layers of the material;
4. Conduct superhard and brittle material turning;
5. Improve the accuracy of product processing;
6. Increase tool life;
7. Improve the surface finish and quality;
8. Eliminate the possibility of self-oscillation when cutting.
