Lapping flat surfaces with forced dosing of abrasive suspension

Abstract

The issues concerning the finishing of flat ceramic seals are presented in the paper. The treatment requirements demanded from the elements of that type cause, that necessary is application of grinding-in in the technological process. Such a precise abrasive treatment of flat surfaces of that type, requires the use of an appropriate suspended matter or abrasive paste. Many factors connected with metal grinding-in shield, components of abrasive suspended matter and the treatment’s technological conditions, have an impact on the treatment’s result. The manner and intensity of the suspended matter’s proportioning in the grinding-in are, are also of decisive nature. A standard, free manner of proportioning, in a continuous manner most often dipping or dropping, results in big losses of abrasive material. A part of abrasive micro-grains is quickly removed from the operating grinding-in shield by the rotating rings leading separators with treated elements and does not take part at all in machine cutting. It considerably increases the tool costs and has an unfavourable impact on the natural environment. Implementation of the forced abrasive suspended matter’s proportioning at the time of the machine grinding-in, considerably reduces these losses.
