In-die solutions CENTROLUB Tap internal lubrication solution 0 The well-tested INTERNAL COOLANT SOLUTION for tap LUBRICATIONfor deep threading applications Improve the tap lifetime and reduce your lubricant consumption As part of our ongoing optimization of customer applications, Pronic is presenting his internal tap lubrication solution which is a substitute then to the external micro lubrication. As this technique is already used in machining operation, we did rely on our partner BASS GmbH (German tap manufacturer) for its expertise. Compared to the external tap lubrication, the internal lubrication provides a regular lubrication on the side of the extrusion. This is a key parameter when the extrusion height is: Moreover, the lubrication is sprayed accurately and locally, so that the part is less soiled. ADVANTAGES WITH INTERNAL COOLANT LUBRICATION: • Lubricant consumption optimization • Continuous coolant and lubricating film between the tap and the side of the extrusion • Accurate lubricant spray Increase of the tap Using tap with internal lubrication lifetime by 60% makes the Lubrication fiLm compared to the between the tap and the extrusion external lubrication side continuous.
