Machine tool having a spindle, the back and forth movement of which actuates a lubrication pump

摘要

The tool has a driving mechanism i.e. positive feed drill, for driving a tool-bearing spindle (6) simultaneously in rotation and in translation. A lubricating system lubricates a piercing tool e.g. cutter. The lubricating system has a lubricant intake module (44) for connecting a lubricant inlet (40) to an internal lubricant pipe. The module forms a lubricant pump for aspirating the lubricant from the lubricant inlet and supplying the aspirated lubricant to the pipe. The forward and backward movements of the spindle along an axis (A) activate the pumping of the lubricant through the module. An independent claim is also included for a method for machining a material using a machining tool.
