To the above problem, the utility model aims at providing a can follow the deformation of work piece along with the flexible CBN emery wheel of type burnishing and polishing, improve machining efficiency greatly, and long service life.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a flexible CBN grinding wheel comprises a circular base body, an elastic steel sheet, a CBN grinding material layer and an elastic filling body; elastic steel sheet is including connecting inner and arc outer end, first through-hole is seted up to the side of arc outer end, and is a plurality of elastic steel sheet evenly arranges the outer circumference of circular base member, each elastic steel sheet connect inner inlay in on the outer peripheral face of circular base member, each adhere to on the outer terminal surface of elastic steel sheet's the arc outer end CBN abrasive material layer, adjacent two set up in the first through-hole on clearance between the elastic steel sheet and each elastic steel sheet the elasticity obturator.
In some embodiments, the inner end of the connecting inner end is formed by bending the inner end of the elastic steel sheet to one side, the formed bending angle is an obtuse angle, and an oblique notch matched with the connecting inner end is formed in the outer peripheral surface of the circular base body.
In some embodiments, the cross section of the arc-shaped outer end is formed by splicing a rectangle and a semicircle, and the cross section width of the arc-shaped outer section is larger than that of the connecting inner end.
In some embodiments, the elastomeric filling is filled with a polyurethane rubber.
In some embodiments, a second through hole is formed in the center of the circular base, and the circular base is made of a metal material.
The utility model discloses owing to take above technical scheme, it has following advantage: the utility model discloses a plurality of elastic steel sheets are arranged to outer circumference equipartition at circular base member, elastic steel sheet's connection inner is inlayed on circular base member's outer peripheral face, adhere to CBN abrasive material layer on the outer terminal surface of elastic steel sheet's arc outer end, set up the elastic filling body in the through-hole between the two adjacent elastic steel sheets and on the elastic steel sheet, both guaranteed the structural strength of whole emery wheel, hardness and wearability, make the emery wheel have flexibility and deformability again, can follow the deformation of work piece along with the type burnishing and polishing work piece, guarantee work piece surface quality and profile precision and uniformity, the utility model provides a problem that exists among the prior art can be overcome to the emery wheel, has machining efficiency height, advantages such as long service life.
