Machine tool with a turret and a system for minimum quantity lubrication

摘要

The invention relates to a machine tool having a drive motor (1) and a clamping system for a tool associated with the drive motor (1), having a system for minimum quantity lubrication, a first line (3) connected to a compressed air source and a second line (2) connected to a lubricant source ( 4). The clamping system is formed by a turret (2) with at least one Mehrspindelbohrkopf (7) or angle head with a plurality of work spindles (8) with associated tool holders, wherein the first line (3) and in one of the number of working spindles (8) corresponding Number of present second line (4) coupled into the turret (2) and through the turret hub (5) to one with the Mehrspindelbohrkopf (7) about the turret hub (5) rotatable distributor disc (9) are guided. On the distributor disc (9) for each Mehrspindelbohrkopf (7) a compressed air transfer line (10) and lubricant transfer lines (11) in a number of the second lines (7) corresponding number arranged and in the working position of Mehrspindelbohrkopfes (7) conductive with the first line (3) and the second line (4), wherein the compressed air transfer line (10) and the lubricant transfer lines (11) lead to a working spindle (8) associated mixing chamber (12) from which a mixing line (13) leads to the tool holder.
