This system of lubrication provides HSS and carbide tools with the correct quantity of lubricant. This allows to extend the life time of these tool bits. It can supply lubrication points precisely and irrespective of temperature. The dispensing times can be set individually. It can be used either with the cutting and beveling PROTEM machines (ranges TTNG, TTLW, MF…) or with any other type of such machines The system of micro-lubrication is completely independent of the machine with which it can be associated.
