Description

A kind of aerial blade cutting tool

Technical field

The utility model relates to cutting tool technical field, is specifically related to a kind of aerial blade cutting tool.

Background technology

Aerial blade processing requires higher to lathe and cutter, it is the typical difficult process component of present mechanical processing industry, it is complex-shaped, material difficulty processing and its accuracy of manufacture requires high, needs to be equipped with some cutters according to its operational characteristic and multiple working procedure is processed, and can not ensure good precision and profile tolerance, cause a lot of product rejection, operating efficiency is not high, and product quality can not ensure, the frequent tool changing of work in-process.

Cause the not high reason of frequent tool changing and machining accuracy to be greatly, wearability and the non-oxidizability of the existing dedicated tool for machining aerial blade are low, and in the cutting of height, tool wear is comparatively large, and chip removal has some setbacks, by the precision of low processing.Tool for cutting machining wearing and tearing are divided into three phases: 1) the initial wear stage: this phase wear is very fast, this is because there is asperity in the tool surface of new milled, and blade is sharper, cutter and workpiece real contact area less, compression is comparatively large, makes rear knife face occur rubstrip very soon; 2) normal wearing stage: this phase wear speed slows down, wear extent increase in time evenly increases, and cutting stable, is effective working stage of cutter; 3) sharply wear stage: cutter rust after normal wearing stage, as continued to cut, temperature will increase severely, cutting force increases, and tool wear sharply increases, in this stage, can not ensure crudy, cutter material consumption is also many, even tipping and completely lose cutting power.

For addressing this problem, the way adopted at present is, at cutting tool surface deposition one deck high-wearing feature and anti-oxidation coat, with significantly improve cutting-tool's used life and meet at a high speed, the severe processing conditions needs such as efficient.And TiAlN coating and laminated coating thereof are owing to having good hardness and antioxygenic property and comprehensive serviceability, it is current widely used coating material.In recent years, some recent studies ons show in TiAlN coating system, add the hardness or the antioxygenic property that promote coating as the elements such as Si, Zr, Cr, Nb, Ta, W, B are all right further.In Ti-Al-N coating, add the nano composite structure wrapping up TiAlN nanocrystal by the Si3N4 phase of amorphous that Si element formed also show super-hardness effect while the antioxygenic property improving Ti-Al-N coating and heat endurance, thus be subject to the extensive concern of cutter coat researcher, and be industrially applied gradually.But this type of hard coat is due to higher with the coefficient of friction of rapidoprint, increase cutting resistance and tool surface glues bits degree, at the exigent manufacture field of some Surface Qualities and airtight processing environment, and lubrication and chip removal are required that higher occasion exists certain familiar lacunas.And the mode of its deposition of existing TiAlN coating is too simple, cause the normal wearing stage coating consumption of cutter in machining serious, although play the effect slowing down tool wear, the service time of normal wearing stage is comparatively of short duration, finally affects it and cuts application.
