Surface adhesion cooling micro-machining tool for minimum quantity lubricant system

Abstract

The invention discloses a surface adhesion cooling micro-machining tool. The surface adhesion cooling micro-machining tool is suitable for a minimum quantity lubricant system. The tool comprises a cutter blade part and a cutter clamping handle, wherein the cutter blade part is axially arranged at one end in an axial direction, the cutter clamping handle is arranged at the other end, at least one inner cooling channel is formed in the tool clamping handle, and the cutter clamping handle is provided with a convex part which protrudes out of the cutter blade part in the radial direction; at leastone inner cooling outlet is formed in the convex part in the axial direction, the inner cooling outlet communicates with the inner cooling channel, and the inner cooling outlet points to the cutter blade portion; and the minimum quantity lubricating oil mist is sprayed from an inner cooling channel to a machining area through the inner cooling outlet, the mists does not scattered, the effects ofcooling, lubricating, chip punching and chip removal are achieved. In particular, the surface adhesion cooling micro-machining tool has better cutting machining performance than a common tool, so thatthe tool is particularly suitable for deep hole machining; and the damage to the appearance of a machined part and the tool due to the high heat during in the high-speed machining of the surface adhesion cooling micro-machining tool is reduced, and a high-speed and high-efficiency deep hole machining tool is brought to the machining industry.

Description

technical field [0001] The invention belongs to the technical field of machining tools, and in particular relates to a veneer cooling micro-machining tool for deep hole machining, suitable for micro-lubrication systems, capable of cooling, lubricating, flushing and removing chips. Background technique [0002] Minimal Quantity Lubricant (MQL) cutting technology is a new type of lubrication method for metal processing, that is, semi-dry cutting is also called quasi-dry cutting, which refers to mixing and vaporizing compressed gas with an extremely small amount of cutting oil to form Micron-sized droplet particles are sprayed into the cutting area at high speed to effectively lubricate the processing part between the tool and the workpiece. [0003] At present, micro-quantity lubrication technology has been widely promoted in various mechanical processing fields. One of the purposes of micro-lubrication is to improve tool life, but most of the structures of existing tools have...

AI Technical Summary

Problems solved by technology

Compared with shallow hole machining, deep hole machining has many difficulties, such as too long chip removal channel and small diameter, making it difficult to remove chips. Failure to remove chips in time will lead to the generation of chip edge, which will scratch the workpiece and easily damage the tool. At the same time, it is difficult to dissipate heat. , the tool is prone to aggravate the wear rate of the tool and reduce the surface accuracy of the workpiece due to the high temperature in the hole
