Electrodeposited diamond coating with protection by diamond micron powder in a dressing tool. Part 2. Tool performance
Autor: M. N. Sheiko, A. P. Maksimenko, P. I. Bologov
Publikováno v: Journal of Superhard Materials. 39:203-209
The paper compares the results of tool life testing of dressing rollers with conventional electrodeposited diamond coating (EDC) and with protected EDC. The protection of EDC by diamond powder is demonstrated to extend the effective tool life (for th

Diamond electroplated coating with protection by diamond micron powder in a dressing tool. Part 1. Coating deposition conditions
Autor: V. N. Skok, M. N. Sheiko
Publikováno v: Journal of Superhard Materials. 39:134-142
The authors put forward a method of protection of diamond electroplated coating in a dressing tool made by the electroforming process. The method consists in using diamond micron powder in the surface layer of the nickel bond in order to protect the

On theoretical substantiation of the choice of effective grain profile shape in modeling of diamond layer in dressing tools. Part 2. Electroforming
Autor: M. N. Sheiko
Publikováno v: Journal of Superhard Materials. 39:57-66
The paper describes, from the statistical standpoint, the mechanism of formation of spherical shape of the averaged cross section of scratches produced by flat faces of diamond grains in abrasive material of grinding wheels during their dressing with

Grain shape as a factor governing the parameters of diamond electroplated coating of dressing tools. Part 3. The simplest 3D model of a diamond grain—'A barrel made of parabolic and circular staves'
Autor: M. N. Sheiko
Publikováno v: Journal of Superhard Materials. 38:207-215
The paper addresses the simplest 3D model—a barrel made of parabolic and circular staves—for a diamond grain in the electroplated coating of dressing tools. It is shown that the proposed concepts of a diamond grain shape provide, on the one hand,

Grain shape as a factor governing the parameters of diamond electroplated coating of dressing tools. Part 2. Actual grain–graphite form contact area and related characteristics as input data for calculating the conditions of diamond electroplated coating application by electroforming method
Autor: O. O. Pasichnyi, M. N. Sheiko, V. N. Skok
Publikováno v: Journal of Superhard Materials. 38:47-50
The paper gives experimental data on the actual contact area between grains and the graphite form used in the process of deposition of a diamond coating onto a dressing tool by the electroforming method. Also, the authors provide the results of deter

Quasi-infeed dressing of abrasive wheels as express test method for diamond form dressing rollers. Part 1. Recording of dressing forces
Autor: P. I. Bologov, O. O. Pasichnyi, V. N. Skok, M. N. Sheiko
Publikováno v: Journal of Superhard Materials. 31:260-266
A test procedure for complex-form rollers is put forward; it involves the so-called quasi-infeed dressing scheme that simulates the real infeed dressing. The procedure requires no specialized expensive equipment but can be implemented on universal eq
