Description

technical field [0001] The invention relates to a vibrating tool holder, in particular to a high-rigidity medium-frequency vibrating tool holder for hole making, which belongs to metal cutting processing and metal cutting equipment components. Background technique [0002] Under the current technical conditions, hole processing, especially deep hole processing, has problems such as difficulty in chip removal, poor rigidity of the process system, and unsatisfactory cutting effect. Vibration hole making technology has good technological effect in the processing of deep holes and difficult-to-machine materials: vibration drilling can significantly reduce drilling force, improve drilling surface quality, improve hole straightness, reduce exit burrs, etc.; vibration reaming It can improve the surface quality, achieve the effect of reaming, and improve the processing efficiency; vibratory reaming can suppress the built-up edge generated in low-speed processing and improve the surf...

AI Technical Summary

Problems solved by technology

The electromagnetic axial vibration device has the advantages of simple structure and high vibration frequency (can be adjusted within tens to hundreds of Hz), but the power of the electromagnetic exciter is small, and it is only suitable for small hole processing

In addition, the existing vibration devices generally use structures such as springs to generate elastic recovery force, resulting in poor rigidity of the process system during vibration cutting, making it difficult to meet the conditions of theoretical vibration cutting, which limits the application range of vibration hole making technology
