Abstract

The invention discloses a high-pressure cooling turning tool, relates to a turning tool, and solves the problems that when the conventional turning tool turns a difficultly-machined material, cutting fluid cannot be sufficiently sprayed to a cutting area due to insufficient cooling and lubricating capacity, and cut chip winds a workpiece and is difficultly broken off due to insufficient chip breaking capacity. The high-pressure cooling turning tool comprises a tool handle, a tool bit and a tool blade, wherein the tool bit is fixedly connected to the front end of the tool handle; the tool blade is embedded into the front end of the upper end surface of the tool bit; the tool blade is fixedly connected with the tool bit through a fastening mechanism; a threaded bind hole is formed in the lower end surface of the tool bit; the tool bit is connected with a high-pressure pipe head through the threaded bind hole; a plurality of cooling liquid passages are formed in the tool bit; one end of each of the plurality of cooling liquid passages is communicated with the threaded bind hole; the other ends of the plurality of cooling liquid passages are arranged towards the front end of the tool blade. The high-pressure cooling turning tool is used for turning a difficultly-machined metal material.

Description

technical field

[0001] The invention relates to a turning tool, in particular to a high-pressure cooling turning tool. Background technique

[0002] Using a reasonable cooling structure can make the cutting fluid fully play its role, which is very important to improve the cutting efficiency and product surface quality. With the conventional cooling method, the phenomenon that the chips are entangled in the workpiece and difficult to break, and the insufficient pressure makes the cutting fluid not sufficiently sprayed into the cutting area. If high-pressure cooling is used, under high pressure, the cutting fluid can accurately reach the cutting area between the rake face of the insert and the chip, which can effectively prolong the service life of the tool and ensure the reliability of the cutting process. The key to cooling during metal cutting is that there should be an intersection between the cutting fluid and the cutting area during machining. The smaller the number of...
