A fluid sterilization apparatus includes: a flow passage for causing a fluid to flow; and a light source that irradiates the fluid flowing in the flow passage with ultraviolet light of a wavelength of 290310 nm. The fluid contains a cutting fluid for a cutting work or Japanese sake in the process of manufacturing.

The present invention provides a lubricant material for assisting machining process comprising a high molecular weight compound (A) having a weight average molecular weight of 5?10.sup.4 or higher and 1?10.sup.6 or lower, a medium molecular weight compound (B) having a weight average molecular weight of 1?10.sup.3 or higher and lower than 5?10.sup.4, and a carbon (C) having an average particle size of 100 ?m or larger.

A method of manufacturing a transmission case housing is provided wherein a minimum quantity of lubrication as a compressed air/oil mist is supplied as the housing is rough bored and face milled. The transmission case defines a plurality of transmission fluid drainage holes for draining transmission fluid from the transmission when installed in a vehicle. The housing is positioned with the fluid drainage holes below a central axis of the housing and a plurality of internal bores and faces are bored and face milled on the housing. The compressed air/oil mist is sprayed from the cutting head to cool and lubricate the boring and face milling tools. Machining chips are blown off the rough bored housing through the fluid drainage holes.

A device for mixing and supplying fluids comprises: a fixing unit provided with a first flow path through which a first fluid flows, a second flow path through which a second fluid flows, and a through-hole; and a rotating unit, which is rotatably provided on the through-hole so as to penetrate the fixing unit, and which is provided at the front end with a fixing hole into which a processing tool is inserted and fixed, and a communication part which communicates with the first flow path and the fixing hole, so as to mix the first fluid and the second fluid and supply the mixture to the processing tool.

Devices, systems, and methods are provided for controlling a quantity of cutting fluid dispensed for a cutting tool within a CNC or other machining system. The devices, systems, and methods may include controlling multiple fluids such that coolant, lubricant, or other fluids can be delivered at different locations, at different flow rates, have their flow rates changed independently, and/or have their flow rates changed dynamically during a machining operation. In some embodiments, a feedback loop or input may be provided to obtain and/or provide information regarding the machining operationsuch as cutting force, cutting temperature, cutting friction, machining operation, tool in use, work piece geometry, and/or materialand automatically and/or independently modify the fluid flow rates. The fluid may be atomized with air or other gases to minimize the quantities of fluid used. Components in the system may be modular to allow the system to be used with existing and new machining technologies.

A microlubrication system for a machining unit with a rotating spindle, the system having a rotary feedthrough via which compressed air and lubricant can be fed to the rotating spindle to combine them in a mixing chamber close to a tool, and a metering valve by means of which the amount of the fed lubricant can be dosed. In order to improve the monitoring and the control of the system, the rotary feedthrough and/or the metering valve are designed as smart components.
