Description
Vynález sa týká spósobu elektrochemického brúsenia tvarových súčastí z tažkoobrobiteíných kovových materiálov.The invention relates to a method of electrochemical grinding of shaped parts made of difficult-to-machine metal materials.
Doteraz sa tvarové súčasti z ťažkoobrobitelných kovových materiálov brúsili klasickými spósobmi korundovými alebo karborundovýml brúsnymi kotúčmi alebo elektrochemicky ocelovými kotúčmi. Sposob tvarového brúsenia korundovými alebo karborundoivými kotúčmi je málo produktívny, kladie vysoké nároky na kvalifikáciu a zručnost pracovníka, pričom u tohoto spóslobu sa nedajú vylúčiť povrchové vady, ktoré vzniknú od teploty pri brúsení. Sposob brúsenia elektrochemicky ocelovými kotúčmi má nevýhodu v tom, že vyžaduje dokoinčovanie tvaru z důvodu dosiahnutia požadovanej přesnosti a kvality opracovanej plo·chy. Brúsenie kotúčmi z kubického· nitridu bóru tvarových súčastí sa používá len klasickým spósobom, čím je tento- spósob menej prloiduktívny a vyznačuje sa nízkou trvanlivosťou tvaru brúsneho kotúča z kubického nitridu bóru.Up to now, shaped parts made of difficult-to-cut metal materials have been ground by conventional corundum or carborundum grinding wheels or electrochemically steel wheels. The shape grinding process with corundum or carborundum wheels is not very productive, it places high demands on the qualification and skill of the worker, and in this way surface defects that arise from the grinding temperature cannot be excluded. The method of grinding electrochemically with steel discs has the disadvantage that it requires the shape to be finished in order to achieve the desired precision and quality of the machined surface. Cubic boron nitride grinding of shaped parts is used only in the classical way, making it less prloidative and characterized by low durability of the cubic boron nitride grinding wheel shape.
Uvedené nedostatky odstraňuje spósob tvarového brúsenia podía vynálezu, jehož podstatou je, že sa tvar súčasti brúsi prostredníctvom tvarových ocelových kotúčov s pevne viazaným brusivom z kubického nitridu bóru.The above-mentioned drawbacks are overcome by the form grinding method according to the invention, which is based on the fact that the shape of the part is grinded by means of shaped steel wheels with firmly bonded cubic boron nitride abrasive.
Pri jednom upnutí sa brúsi najprv elektrochemickým spósobom a dokončuje sa abrazívnym spósobom, pričom pevne viazané brusivo z kubického nitridu bóru pri elektrochemickom procese znásobuje účinky a umožňuje celý tvar vybrúsiť na jeden úber, potom pri spatném pohybe, po vypnutí generátora elektrochemického procesu, prípadnom následnom nastavení minimálneho přídavku na dokončeme tvaru sa tvar dokončuje.In one clamping, it is abraded first in an electrochemical process and finished in an abrasive manner, whereby the firmly bound abrasive of cubic boron nitride in the electrochemical process multiplies the effects and allows the entire shape to be ground in a single removal. the minimum allowance to complete the shape is the shape is completed.
Účinky spósobu elektrochemického tvarového brúsenia tvarových súčastí sa vyznačujú vysokou produktivitou obrábania, vysokou presnosťou a kvalitou opracovaných tvarových plóch. Minimálně namáháme brúsneho kotúča, respektive minimálně přídavky na dokončeme zabezpečujú vysokú trvanlivost a rozmerovú stálost tvarového ocelového kotúča s pevne viazaným brusivom z kubického nitridu bóru.The effects of electrochemical shape grinding of shaped parts are characterized by high machining productivity, high precision and quality of machined shaped surfaces. We minimize stress on the grinding wheel, or at least the finishing allowances ensure high durability and dimensional stability of the shaped steel wheel with tightly bonded cubic boron nitride abrasive.
Týmto sposiobom sa dosahujú uvedené účinky najma pri výrobě tvarových súčastí z ťažkooibrobiteíných kovových materiálov, ako sú tvarové eústružnické nože z vysokovýkonných tažkoobrobiteíných oděli.In this way, the aforementioned effects are achieved, in particular, in the production of shaped parts from difficult-to-machine metal materials, such as shaped e-cutting tools from high-performance difficult-machine parts.
S výhodou je uvedeného spósobu možné použiť například pri brúsení tvarových sústružníckych nožov z rýchlorezných ocelí po tepelnom spracavaní, kde ocelový kotúč s pevne viazaným brusivom kubického nitridu bóru má protitvar noža a na jedno upnutie. noža a jeden pracovný cyklus sa vyrobí tvar noža na hotovo tak, že prvý úkon, hrubióvacie brúsenie tvaru sa robí elektrochemicky a pri vratnom pohybe obrobku, po dostaitočnom nastavení prídavkov pre obrábanie, sa tvar dokončí tým istým kotúčlom na hotovo abrazívnym spósoibloím.'Advantageously, the method can be used, for example, in the grinding of high-speed steel turning tools after heat treatment, wherein the steel disk with the firmly bonded cubic boron nitride abrasive has a knife counter-shape and for a single clamping. The shape of the knife is made ready for use in such a way that the first action, the roughing of the shape, is done electrochemically and when the workpiece is reciprocated, after the machining allowances have been sufficiently adjusted, the shape is completed with the same abrasive grinding wheel.
