Title:
MACHINING COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/002451
Kind Code:
A1
Abstract:
[Problem] To provide a machining cooling device that can perform cooling properly even when machining with a tool progresses deep into a workpiece. [Solution] An outlet 13 of a direction changing part 11 is provided on a front surface of a projecting part 8. This makes it possible to place the outlet 13 in the vicinity of a tool 6 supported by a tool holder 5. Placing the outlet 13 in the vicinity of and adjacent to the tool 6 supported by the tool holder 5 allows a cooling oil 7 to be injected from the outlet 13 along an outer surface of the tool 6 and in parallel therewith so as to be close enough to come in contact therewith. Thus, even when machining of a workpiece 2 with the tool 6 progresses deep into the workpiece 2, most of the cooling oil 7 injected from the outlet 13 reaches, through a gap between an internal hole 23 of the workpiece 2 and the tool 6, a machined portion located deep in the workpiece 2 and defined by the workpiece 2 and a tip of a cutting part 18 of the tool 6, without being splashed by a front surface of the workpiece 2 facing a jet orifice part 10. As a result, the machined portion defined by the workpiece 2 and the tool 6 is cooled properly by the cooling oil 7.
