The appropriate minimal quantity lubrication system, which is fastened with a fixing screw will fit all CNC milling machines. It can be operated with eg a small compressor, where a minimal air pressure of 2 bar is necessary. Fine tuning of amount and air pressure can be adjusted via nozzle as well as switch. All tubing is made of stainless steel and therefore resistant to corrosion. The suction side is equipped with a filter. If extensions are needed, ordinary plastic tubing or appropriate high pressure tubing can be used. An ordinary ‘biker drinking flask’ is sufficient to use as a vessel. The minimal quantity lubrication system will be used most when dealing with soft materials which are difficult to mill, such as aluminium in pure form or copper. These materials can not dispense a minimal lubricating system!
