MEASUREMENTS OF LAPPING PLATE TEMPERATURE

Journal Title: Journal of KONES - Year 2014, Vol 21, Issue 3

Abstract

Lapping process is commonly used for ultra-precision machining of various materials. An essential role during lapping plays flatness of the wheel-working surface because workpiece surface takes mirror image of it. Due to its applications requiring extreme size accuracy, straightness and concentricity, it is very important that working surface remains flat in the course of machining. Getting out of flatness can be caused by uneven wear or heating. To prevent nonuniform wear of lapping plate surface, conditioning rings should be suited appropriate. Lapping machines producers and researchers makerecommendations about proper rings position during machining. To provide constant temperature of the wheel, cooling systems are applied in modern machines, but not in all of them. Therefore, wheel temperature problem is significant one, and it should be known. This paper presents results of authors work on choosing proper measurement method of lapping plate temperature. During lapping process wheel is rotating. Maximum velocity value for ABRALAP 380 lapping machine is 65 rev/min.Mainly for this reason, contactless infrared method was selected. Because getting an accurate temperature of an object using this method is difficult, during experiments temperature rise not exact value were analysed. There were also presented results of experiments which goal was to find lap plate emissivity.
