AUTOMATICALLY CONTROLLED APPARATUS FOR FEEDING CUTTING FLUID TO CUTTING ZONE Russian patent published in 2001 - IPC

FIELD: metal working, namely apparatuses for feeding vaporized cutting fluids to cutting zone of metal cutting machine tool. SUBSTANCE: automatically controlled apparatus for feeding cutting fluid to cutting zone includes feeder and steam generator joined with feeder, thermostatically controlled electric heater built in steam generator and branch pipe for discharging steam. Apparatus also includes control system with microprocessor for controlling processes of preparation and feed of cutting fluid to cutting zone, locking device with servodrive connecting feeder and steam generator. Feeder is provided with pickup for detecting lower liquid level. Vapor generator is provided with pickup for detecting pressure of vaporized cutting fluid and pickup for measuring temperature of heat generating electric heater. All above mentioned pickups are connected with respective information inlets of control system having microprocessor. Control outlets are connected with servodrive of locking device and with thermostatic controller of electric heater. EFFECT: enhanced reliability of apparatus for feeding vaporized cutting fluid to cutting zone due to improved design of apparatus and use of microprocessor in control system. 4 dwg
