Summary: The article is aimed at when machining, cutting tool is in use process contact for long with the workpiece that be added, bring about sex of cutting tool blade to drop, influence cut speed and quality this one problem, designed blade of a kind of mechanical cutting tool to wear device. This device is simple practical, cost is low, went to the lavatory greatly the cutting tool blade of personnel of operation of machine tool a gleam of grinds the job, the sharp edge blade that solved cutting tool well and cutting tool repeat recycle question. Keyword: Cutting tool; Cutting; Blade grinds device 　 the core part that 0 foreword cutting tool is cutting treatment machining complex, of cutting tool wear away or damaged can cause difference of workpiece surface quality not only, productivity is low, manufacturing cost is high, and serious when the breakdown of the functional be no longer in force that still can create a machine tool and whole system, accordingly, cutting tool blade grinds special key. Normally cutting tool blade grinds organic tool blade is ground and manual blade grinds two kinds, mechanical blade grinds efficiency angle of tall, geometry accurate, quality good, operation is convenient, conditional when should preferential use. Manual blade is ground more agile, inferior to grinding knife equipment to ask, this kind of blade grinds a method more commonly used. Traditional manual blade grinds a method is handlers normally hold cutting tool to undertake burnish on emery wheel, such operations are breakneck, once appear,error can cause very big person accident, because this article designs blade of a kind of mechanical cutting tool,grind device to undertake blade is ground assisting cutting tool. The article is aimed at content of 1, research in machining process, because cutting tool is long be contacted with the workpiece that be added and bring about blade sex to drop, affect the issue of cut speed and quality, be about to design a kind simple and practical, tear open outfit is agile, the cutting tool blade with high security wears device. Each equipment that in grinding a process through analysing cutting tool blade, requires, to add element of the scientific sex of the design, rationality, aggrandizement holds the use value of buy, all sorts of dangerous hidden danger that cogent consideration reduces the likelihood in actual unit process of cargo bandling to arise, designed following cutting tool blade to wear device. 2, structure comprises blade of mechanical cutting tool to if the graph is shown 1 times,wear device, its composition includes: Base 2, the underside of base is in installation to have damping quadrilateral 1, the installation on base has X axis workbench 11, y axis workbench is had on X axis workbench 10, have on Y axis workbench rotate workbench 9, x axis workbench, Y axis workbench, rotate workbench correspondence has emery wheel 5, emery wheel is secured in electric machinery on the take-off of 4, the two end of electric machinery have controller 3 with lighting installation 6. The whirl that blade of mechanical cutting tool wears device the working mesa of workbench is electro-magnet, rotate cutting tool chamfer is had on the working mesa of workbench 8, rotate workbench has transparent cover 7. To facilitate the job also is safe for the purpose of, blade of mechanical cutting tool ground device to still add lighting installation, include base among them, the join on base has coiled pipe coiler, join of top of coiled pipe coiler has chimney. Graph blade of 1 mechanical cutting tool grinds blade of cutting tool of machine of plant construction sketch map to grind device to pass 4 damping be linked together with total workbench, this structure facilitating installation and disassemble. Damping the structure is shown 2 times like the graph, include to go up join board 15 with next join board 12, join board is mixed on below mainstay is had between join board 13, pillar coat has spring 14, join board and base pass bolt join on, issue join board to be secured through bolt and total workbench. Graph 2 damping blade of cutting tool of machine of principle of 　 3, job grinds rigid structure sketch map when device is undertaking use and be operatinged, will whole blade grinds device to pass damping fixed go up in total workbench, secure through bolt make its more smooth. The cutting tool that need blade grinds is placed rotating inside the cutting tool chamfer of workbench. Because rotate,the working face of workbench uses electro-magnet, pass electro-magnet adsorption cutting tool, the method of so fixed cutting tool is very firm, won't produce the phenomenon that cutting tool breaks away from. Rotating at the same time the scintilla in transparent cover is being installed to be able to avoid to grind a process in blade on workbench is splashed shoot brought harm. Undertake through X axis workbench, Y axis workbench X axis and Y axis move, through rotating workbench undertakes angle adjustment, realize the cutting tool burnish of each azimuth, undertake through lighting installation smooth illume makes at the same time handlers can more clearly observation blade worries a situation. 4, note uses this device effectively for safety, grind in cutting tool blade the following respects should note in the process: When blade is ground, must take above all defend lens, handlers should stand in grinder flank by the requirement; Emery wheel should be checked to have before blade is ground without break, use emery wheel front to grind a knife; The lathe tool that should grind blade is in emery wheel is circumferential on or so shift, make emery wheel wear and tear even, do not appear groove, avoid the cutting tool of two flank kibble in emery wheel as far as possible, emery wheel of as a result suffers force to slant place, jumpy, broken even; Next, when in the light of different sort cutting tool blade is ground, what need a note to differ somewhat. When blade grinds hard alloy cutting tool, cannot cool in cooling fluid with preventing bit to contract suddenly disintegrate; When blade grinds high-speed steel cutting tool, need to have enough refrigeration, lest cutting tool passes because of grinding the temperature when the knife tall and anneal, weaken the cutting function of cutting tool; Finally, when still answering to grind an end in blade, conveniently shuts blade to grind device power source. Blade of this mechanical cutting tool grinds 5, epilogue device not only structure simple, operation is convenient, the setting of transparent cover and lighting installation also reduced the dangerous sex of the operation greatly. It is OK to adopt this device very good to wearing away cutting tool undertakes blade is ground, blade is ground shake in the process small, it is good that blade grinds the effect, went to the lavatory greatly the cutting tool blade of personnel of operation of machine tool a gleam of grinds the job.
