Lapping is used in the production of components of the highest quality in terms of form finish accuracy and surface integrity. A number of precision manufacturing applications use lapping process as a critical technology to achieve thickness tolerance and surface quality specification. Because of required parts accuracy tool flatness is the key to the successful machining. To avoid its excessive thermal expansion, plate temperature research was taken. This work presents a part of results concerning temperature measurements conditions. Experiments were being conducted during flat lapping with use of ABRALAP 380 lapping machine and infrared camera V-20II produced by VIGO System SA. Firstly the influence of conditioning rings number on wheel temperature rise was investigated. It was proved that number of rings had a significant impact on temperature rise value and the highest were during machine working with all three rings. Then another test was made, to simulate the work during real 8-hours shift. The aim was to determine time of machine working after which temperature would stop rising. Temperature was measure during Al2O3 (95%) elements lapping with use of silicon carbide grains. Tests results showed that after five hours temperature fluctuated around a certain value. In future analysis temperature after five hours lapping will be taken into account.
