Machine tool having internally routed cryogenic fluid for cooling interface between cutting edge of tool and workpiece

This machine tool is utilized for cutting super alloys. The tool is associated with a source of cryogenic coolant which is routed internally through the tool. The coolant is discharged from the tool at a precise angle such that the stream of the coolant at the interface between the tool cutting edge and the workpiece is such that the chip cutting from the piece does not interfere with the coolant stream. The coolant passage is insulated to prevent boiling of the coolant until it reaches the cutting edge to obtain maximum heat dissipation.

Temperature management for a cryogenically cooled boring tool

A cryogenically cooled boring tool design reduces the effect of cryogen coolant on a workpiece caused by coolant leakage and coolant exhaust. A tool body has a cartridge for holding a cutting tool insert and a coolant supply path through the tool body and the cartridge for supplying cryogenic coolant to the tool insert. A feed transfer tube connects the coolant supply path in the tool body to the coolant supply path in the cartridge. Insulating tubes line portions of the coolant supply paths in the tool body and the cartridge. The shrinkage rates of the feed transfer tube and the insulating tubes cause the press fit of the insulating tubes to tighten the seal between the insulating tubes and the feed transfer tube when cryogenic coolant flows through the supply path. The exhaust ports on the tool for boiled-off cryogen remains outside of a workpiece bore.

Rotary cutting tool with an internal cooling cavity

내부에서 극저온 유체에 의해 냉각되는 회전 절삭 공구는 대략 원통 모양의 외형을 갖고 있다. 적어도 하나의 플루트가 절삭 공구에 형성되고, 절삭날이 소재의 절삭을 위해 플루트의 외측 선단에 형성된다. 극저온의 냉매를 위한 내부의 저온 흐름 전달 경로는 절삭날에 근접하여 있다. 냉매 캐비티는 내부의 저온 흐름 전달 경로에 극저온의 냉매를 공급하도록 절삭 공구 내에 형성되고, 극저온의 냉매를 위한 복귀 경로가 저온 흐름 전달 경로의 하류에 있다. 배출구가 극저온의 냉매를 대기로 배출하기 위해 복귀 경로에 연결된다. 배출구는 절삭날로부터 멀리 떨어져 있어, 극저온의 냉매가 절삭날과 소재로부터 멀리 배츨됨으로써, 극저온의 냉매가 소재를 냉각하고 강화시키지 않게 된다. The rotating cutting tool, which is internally cooled by a cryogenic fluid, has an approximately cylindrical shape. At least one flute is formed in the cutting tool, and a cutting edge is formed at an outer tip of the flute for cutting the workpiece. The internal cold flow delivery path for the cryogenic refrigerant is close to the cutting edge. A refrigerant cavity is formed in the cutting tool to supply cryogenic refrigerant to an internal cold flow transfer path, and a return path for the cryogenic refrigerant is downstream of the cold flow transfer path. An outlet is connected to a return path for evacuating the cryogenic refrigerant to the atmosphere. The outlet is far away from the cutting edge so that the cryogenic refrigerant is vented away from the cutting edge and the material, so that the cryogenic refrigerant does not cool and harden the material.
