A kind of cutting edge processing technology

Abstract

The invention provides a tool edge processing technology. The tool edge processing technology comprises the following steps that 1, a left hand holds a tool, the tool is placed on a fixed base to enable a tool edge to be parallel to the horizontal datum line of the fixed base, and a right hand holds a file to machine the tool edge; 2, the tool machined with the file is placed in a polishing machine, wherein the revolving speed of the polishing machine is set as 45 r / s, the clockwise polishing time is set as 10 minutes, and the anticlockwise polishing time is set as 2 minutes; 3, a superfine velvet wheel brush is clamped to a wheel brush instrument, the tool is placed on a working table arranged under the superfine velvet brush to be subjected to finish polishing machining, and after machining is finished, the tool is taken down, wherein the revolving speed of the wheel brush instrument is set as 200 r / s, and the time is set as 1.5 minutes. After the tool is machined through the processes, sawtooth-shaped grain and small cracks of the tool edge are detected on an amplification detector, the grain and pits obviously become shallower, smaller and fewer, and some tools even can achieve a grain-free and pit-free state.

Description

technical field [0001] The invention relates to the technical field of tool processing, in particular to a tool edge treatment process. Background technique [0002] As customers' requirements for tool durability continue to increase, the requirements for tool wear resistance are getting higher and higher. For tools with high durability requirements, the wear resistance of tool raw materials, tool coatings, and The wear resistance of the cutting edge has higher requirements. The patent of the present invention has made obvious improvements to the edge treatment of the tool to improve the durability of the edge of the tool, thereby meeting the high durability requirements of customers. [0003] General tool edge treatment tools include files, whetstones, and polishing sand. The edge treatment methods are divided into processing with a single tool or a combination of multiple tools. The following are the specific situations of using several tools: [0004] 1. Only use a fil...

AI Technical Summary

Problems solved by technology

[0004] 1. Only use a file or oil stone for processing. After production, the cutting edge of the tool is detected on a magnifying inspection instrument. There are obvious jagged lines, the lines are very thick and deep, and the effect of improving the cutting edge cannot be achieved.

[0005] 2. Only use polishing sand for processing. After production, the cutting edge of the tool is detected on a magnifying inspection instrument. There are obvious small pits, and the pits are too large and too many, which cannot achieve the effect of improving the cutting edge.

[0006] 3. Use the combination of file and polishing sand, oil stone and polishing sand, file and oil stone and polishing sand to process. The jagged lines and small pits are slightly improved, but the jagged lines and small pits still exist, and they are still relatively thick. , deeper, more, larger, and after processing in combination, jagged lines and small pits exist at the same time, which reduces the wear resistance of the cutting edge

[0007] Combining the above forms, the cutting edge made by using the above tools is detected on the magnifying inspection instrument. The cutting edge is relatively rough, with obvious jagged lines and tiny pits. The powdery iron filings generated by the cutting tool during use will accumulate In the lines and pits, because the iron filings are in a high temperature state during processing, if they accumulate on the cutting edge, the cutting edge will be in a high temperature state for a long time, and small cracks will appear on the cutting edge, the cracks will continue to expand, and the cutting edge will chip. , resulting in the tool not being able to continue to be used, the wear resistance of the tool edge cannot be improved, and ultimately the durability of the tool cannot be improved
