Abstract
Abstract In the operation of at least one machine tool having at least one cutting tool, at least one spindle and at least one slide, a fluid lubricant is fed to the spindle and to the slide. This fluid lubricant is a water-emulsifiable composition consisting essentially of a mineral oil together with an emulsifying agent capable of causing the mineral oil to form a stable emulsion with water. At the same time, there is fed to the cutting tool an aqueous emulsion consisting essentially of water, a mineral oil and an emulsifying agent that maintains the emulsion stable. The overflow or leakage of the fluid lubricant is mingled with the overflow of the aqueous emulsion, and the commingled fluids are collected. Then solids are removed from the commingled fluids to regenerate a clean aqueous emulsion, and the composition of the regenerated aqueous emulsion is adjusted by adding ingredients thereto, to bring the regenerated aqueous emulsion to substantially the same composition as the aqueous emulsion initially fed to the cutting tool, and the regenerated aqueous emulsion is recirculated to the cutting tool.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
A method of lubricating at least one machine tool having at least one cutting tool, at least one spindle and at least one slide, comprising the steps of (a) feeding to such Spindle and to such slide a fluid lubricant that is a water-emulsifiable composition consisting essentially of a mineral oil together with an emulsifying agent capable of causing the mineral oil to form a stable emulsion with water, (b) feeding to such cutting tool an aqueous emulsion consisting essentially of water, a mineral oil and an emulsifying agent that maintains the emulsion stable, (c) mingling the overflow of the fluid lubricant with the overflow of the aqueous emulsion, (d) collecting the commingled fluids, (e) removing solids from the commingled fluids to regenerate an aqueous emulsion, (f) adjusting the composition of the regenerated aqueous emulsion by adding ingredients thereto to bring the regenerated aqueous emulsion to substantially the same composition as the aqueous emulsion initially fed to the cutting tool, and (g) recirculating the regenerated aqueous emulsion to the cutting tool.
Claim 2
Independent Claim
171 words
A method of lubricating at least one machine tool having at least one cutting tool, at least one spindle and at least one slide, comprising the steps of (a) feeding to such Spindle and to such slide a fluid lubricant that is a water-emulsifiable composition consisting essentially of a mineral oil together with an emulsifying agent capable of causing the mineral oil to form a stable emulsion with water, (b) feeding to such cutting tool an aqueous emulsion consisting essentially of water, a mineral oil and an emulsifying agent that maintains the emulsion stable, (c) mingling the overflow of the fluid lubricant with the overflow of the aqueous emulsion, (d) collecting the commingled fluids, (e) removing solids from the commingled fluids to regenerate an aqueous emulsion, (f) adjusting the composition of the regenerated aqueous emulsion by adding ingredients thereto to bring the regenerated aqueous emulsion to substantially the same composition as the aqueous emulsion initially fed to the cutting tool, and (g) recirculating the regenerated aqueous emulsion to the cutting tool.
Claim 3
Dependent Claim
22 words
A method according to claim 1 wherein the fluid lubricant and aqueous emulsion are fed simultaneously to a plurality of machine tools.
Claim 4
Dependent Claim
67 words
A method according to claim 1 wherein the aqueous emulsion fed to the cutting tool is an aqueous emulsion of a composition that is substantially the same as the fluid lubricant fed to the spindle and to the slide, and deionized water is added to the regenerated aqueous emulsion to bring it to substantially the same composition as the aqueous emulsion initially fed to the cutting tool.
Claim 5
Dependent Claim
42 words
A method according to claim 1 wherein a hydraulic fluid that comprises a mineral oil together with an emulsifying agent that causes the mineral oil to form a stable emulsion with water is supplied to a hydraulic system in the machine tool.
