Enterprises need to use green manufacturing technology in the production with the increasingly demanding of environmental requirements. Cryogenic minimum quantity lubricant(CMQL), a new green cutting technique meeting the requirements of green manufacturing, is widely use in production. a pneumatic-control hydraulic system which used in CMQL was introduced,in which minimum quantity lubrication and vortex tube cooling technology were used.Designing pneumatic, hydraulic and electrical subsystem,a sample was finished and some relevant experiments were made. The experimental result is helpful for the advance of minimum quantity lubrication device.
