Technical Field

The invention relates to the technical field of machining equipment, in particular to an efficient micro-vibration honing head.

Background

Honing is a cutting technology with wide prospect, and can effectively improve the dimensional precision, geometric shape precision and surface roughness of parts. When in honing, the honing head on the honing machine rotates and reciprocates, so that the processing surface forms a crossed spiral line cutting track. When the honing head rotates for one circle, the honing strip embedded on the cutter and the cutting track of the previous rotation have a section of overlapping length in the axial direction, so that the connection of the front and rear grinding tracks is smoother and more uniform. Compared with grinding, honing has the characteristics of capability of reducing physical labor of operators, high productivity, easiness in realizing automation and the like, so that the honing tool is widely applied to manufacturing industries of ships, bearings, war industries, engineering machinery and the like. The existing honing equipment mainly adopts a honing mode of reciprocating honing through oilstones, has low machining precision and dimensional stability when machining some miniaturized workpieces, and needs to repeatedly machine on a machining surface, so that the honing machining speed is low, and the production efficiency is low.
