The present invention describes a chemically-assisted machining process that converts conventional lubricant chemistries to produce reactive oxygenated species that accelerate the formation of friction-reducing boundary layer lubrication during cutting operationstermed Ozonolytic Machining. The new type of cooling-lubricant chemistry is based on chemical reactions between unsaturated bio-based oils and alcohols, and other types of machining lubricants, containing carbon-carbon double or triple bonds, with ozone gas to form variously reacted or polymerized ozonidestermed super-oxygenated fluids, oils or alcohols, aldehydes or ketones, sulfurized ozonides and super-oxygenated gels.

Disclosed is an adjustable ultrasonic micro-jet nozzle array with minimal quantity lubrication, relating to cooling of machining. The array-type nozzle includes an inlet conduit, a recycle conduit and a cooling body having a microjet ejection assembly and a recycling assembly. The cooling body includes a microjet ejection chamber which is closed. The inlet conduit is provided at a top of the cooling body and communicates with the microjet ejection chamber.

A mist extraction system is provided that includes a plenum box having an inlet configured to be coupled in fluid communication with a machine tool enclosure. A blower is coupled in fluid communication with the plenum box and is configured to draw air into the plenum box from the machine tool enclosure via the inlet of the plenum box and exhaust the air back into the machine tool enclosure via an outlet of the blower. A baffle plate is arranged in the plenum box to redirect the air drawn into the plenum box through the inlet of the plenum box and a filter panel is arranged in the plenum box to filter the air redirected by the baffle plate prior to the air entering the blower. A collector arranged to collect mist from the air condensed on the baffle plate and the filter panel.

A MQL system for accurately measuring and controlling a volume and pressure of a lubricating fluid provided to a machining tool during minimum quantity lubrication machining operations. The MQL system can further include measuring and controlling a volume and pressure of air provided during machining such that atomization of the lubricating fluid with the air can be controlled. Use of a continuous volumetric flow pump provides a continuous flow of lubricating fluid to the tool during machining operations.

A thread tap includes a shaft and teeth. The shaft includes helical passages from the threading end to the base end of the shaft. Each passage opens through an aperture in the threading end. A second tap includes a cap and the shaft includes an axially extending passage.

A third tap includes teeth spaced apart by a plurality of linear flutes. The shaft includes a central passage and a plurality of flute passages. Each flute passage extends radially outward from a common location in the central passage to a corresponding one of the flutes. The central passage is closed to a terminal end of the threading end.

A holder for a cutting tool of the present disclosure extends from a first end toward a second end, and includes an inflow port, an outflow port located at a side of the first end, and a flow path extending from the inflow port toward the outflow port. The outflow port includes a first opening and a second opening. The flow path includes a first flow path extending continuously from the inflow port, a second flow path extending continuously from the first flow path through a first branch port to the first opening, and a third flow path extending continuously from the first flow path through a second branch port to the second opening.

A minimum quantity lubrication (MQL) system includes a controller, a lubricant module coupled to a tool spindle of a machining apparatus, and a pneumatic module coupled to the spindle. The lubricant module is configured to supply lubricant at pressure to the tool, as controlled by the controller. Likewise, the pneumatic module is configured to supply pressurized air to the tool, as controlled by the controller.
