Cleaning of tool and machine parts via CO2-particles
Pages: 40 - 45
So far, the cleaning of tools in wood-machining industry has been an expensive process, in which the tool has to be removed from the machine and has to be cleaned separately. A deterioration in machining-quality is caused by adhesions consisting of resin and dust resulting from the machining. Thus, the cleaning and therefore the removal of the tool is indispensable although the cutting edge is still sharp and normally it would not have been necessary to remove it for sharpening. This process causes, besides machine downtimes due to the tool removal, additional tool costs. Once the tool has been removed, it is not only cleaned but also sharpened at the same time in order to avoid further machine downtimes. To find a solution which makes it possible to clean tools while being integrated in the machine, CO2 snow-jets for the cleaning of tools have been the subject of research. The main aim was the development of a process-integrated cleaning procedure via CO2 snow-blasting which additionally cools the tool.
