Method for removing cold welded aluminium on cutter and aluminium chips in cutting channels

Abstract

The related method to remove cold-welded aluminum and aluminum bits on cutting channel comprises: (1) selecting 18-20% HCl and the container with section maximal line between opposite anlges larger than the target section about 8-10mm, and the height of HCl in container should over the cutter 1-1.5mm; (2) putting the part with aluminum into HCl solution for 5-15min; (3) every 1-2min, taking out the cutter for look, if the residual aluminum loose, taking out the cutter to sort and clean in water. This invention can remove the aluminum on paths of cutter and handle with low cost and no damage to cutter or human.

Description

technical field [0001] The invention relates to a method for removing cold welded aluminum on a cutting tool and aluminum chips in a cutting channel. Background technique [0002] When machining aluminum workpieces, it is often necessary to use tools, such as boring tools, drills, turning tools, etc. In the process of processing, if the cooling is not enough during cutting, such as: the cutting fluid cannot reach the cutting part, or the state of the tool is poor, such as: blunt blade, rough surface, improper selection of tool speed, etc. The cold welded aluminum formed under the pressure adheres to the cutting edge and the inverted fixture, and the aluminum chips block the cutting fluid channel. The production of cold welded aluminum will reduce the service life of the tool or make it unusable. The cutting fluid channel in the tool holder is blocked so that the tool cannot be used, resulting in the scrapping of the tool holder handle and boring tool bar worth 30,000 to 40,...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: 1. It can only remove very slight cold-welded aluminum on the tool and a small amount of aluminum chips in the cutting fluid channel of the drill bit, and it is generally not easy to remove and unclean; 2. The surface of the tool is not smooth after cleaning; 3. .The removal efficiency is very low (generally about 2 hours); 4. It is easy to damage the surface

For the groove of the blade pressing screw head on the tool holder, the reference hole of the thimble, the complicated corners on the tool holder, more aluminum chips in the through hole in the cutting fluid, thicker cold welded aluminum on the surface of the tool holder, etc. etc., the above method cannot clear
