To guarantee the longest possible tap life, outside oil quality, the most important factor is the means of delivery of the lubricant to the tap. Among the different techniques available, PRONIC has chosen a solution by micro-lubrication that, as well as guaranteeing the longest life possible, limits oil consumption, thereby lowering the price per part.
For certain applications (reinforced collets, for example), lubrication through the center of the tap gives the best performances and leads to parts being kept very clean, thus avoiding in certain cases the washing operation.
