Description
- The object of the invention is an apparatus and method for deburring and roller-burnishing machine parts.
- Progress in machining technology has produced an increasing demand for methods that can provide burr-free machine part surfaces with high abrasion resistance and low surface roughness. Conventional methods aiming at satisfying this demand are deburring, burnishing and roller-burnishing technologies.
- Deburring methods can be known from Deburring and Edge Finishing Handbook by La Raux K. Gillespie (ASME Press, New York, 1989) and from Handbuch Entgrattechnik by Hans-Michael Beier (Carl Hauser Verlag, München-Wien, 1999) which describe more than a hundred different manual and machine methods for deburring. The most widely known methods include mechanical machining technologies such as lathing, boring, grinding, abrasive grinding, sandblasting, thermal machining (laser, electron beam, gas jet), chemical and electrochemical technologies.
- However, the above sources equivocally put an emphasis on the fact that mechanical machining (cutting) technologies cannot fully succeed in completely removing burrs, especially when working with ductile materials, because after each cutting operation some kind of burr remain there on the surface, even if the remaining burrs are extremely small and can be characterised as micro-burrs. The only place where an "edge roiling" technology is mentioned in the above sources is on page 370 of Deburring and Edge Finishing Handbook by La Raux K. Gillespie, where the process is described as rolling burrs back on the surface of the workpiece, avoiding thereby any further cutting and thus the occurrence of micro-burrs.
- Sources that present burnishing and roller-burnishing technologies (e.g. Gépipari megmunkálások by Gribovszky László, Tankönyvkiadó, Budapest, 1977) include both methods in the group of mechanical finishing technologies, their aim being changing the surface quality, roughness, hardness, or residual stress condition by local (surface) mechanical working, without removing any material. Known methods apply special devices having shaping bodies of spherical shape (rollers, balls) that are sufficiently harder than the material of the workpiece. These bodies are mechanically pressed against the surface of the workpiece, with the tool being moved about the surface of the work while either the tool or the workpiece itself is rotated. These movements result In that the shaping bodies are rolled or, in case of (non-roller) burnishing, slid along the surface.
- Existing roller-burnishing technologies that are more closely related to the present invention can be applied for machining inner or outer cylindrical surfaces, flat or spatial surfaces of revolution, and threads.
- Such methods can be known from the page www.fette.de. A special method is described on the homepage of Hegenscheidt HFD GmbH, www.hegenscheidt-mfd.de, the method providing that pre-rolling fine cutting and roller-burnishing itself can be carried out in a single step.
- The German company mentioned above has been granted several patents and has also filed numerous patent applications in the field.
- One of these is patent description
HU 267 962 - Patent description
HU 267 475 EP 146 9972 , while patent descriptionEP 145 2272 discloses a process of roller burnishing crankshaft surfaces. - Common characteristics, and common disadvantages, of the above methods are that they can be utilised only for working continuous surfaces of revolution, flat or helicoid surfaces, that they require complicated equipment and precise machine tools, and that they cannot be applied for deburring. Tensioning force of the roller tools is provided using hydraulic means, and there is no possibility for force adjustment/correction during operation.
- Remarkable solutions are discussed in patent documents
RU2077416 RU2077417 - It is the aim of this invention to provide an apparatus that generates rolling force by a magnetic field that is freely adjustable during operation, and that is capable of roller-burnishing continuous and non-continuous rotationally symmetrical and asymmetrical surfaces (flat surfaces, general spatial surfaces) as well as rolling edge burrs produced at the edges formed at the connection of these surfaces.
- The inventive apparatus should be mountable on conventional and CNC-machine tools.
- The invention is based on the recognition that with suitably configured means it is possible to produce magnetic fields for pressing the magnetisable roller balls against the surface of the workpiece with the desired force, and so mechanical tool tensioning is not needed. The balls are flexibly pressed against the surface so that they can follow minor surface irregularities and edge cracks. Compression force can be adjusted during the process if desired.
- The aim of the invention can also be realised by utilising a powerful permanent magnet that is preferably placed over the work to be machined such that the roller balls remain pressed against the surface of the workpiece, and follow it.
- A further aim of the invention is to provide a method that has the steps of pressing the magnetisable roller balls against the surface of the workpiece by means of magnetic field and performing the desired surface smoothing operation by moving the balls along the surface in a way determined by the possibilities of the given machine tool.

claim - The method according to the invention is disclosed in
claim 8. - A preferred embodiment of the inventive apparatus and the inventive method is explained in detail with reference to the attached drawings where
-
Fig. 1 is the side view of the embodiment of the inventive apparatus that comprises an electromagnet and can be applied for roller-burnishing and deburring workpieces with plane or general spatial surfaces, -
Fig. 2 shows the sectional view of the embodiment comprising a permanent magnet, -
Fig. 3 shows a magnified view of the working zone of the apparatus shown inFigs. 1 - and 2, and
-
Fig. 4 is the front view of the apparatus shown inFig. 1 , taken while machining a cylindrical-surface work. -
Fig. 5 is the over-view of the workpieces shown inFig. 4 . - The apparatus of
Fig. 1 can be utilised for machining aworkpiece 2 having plane or general spatial surface, with theworkpiece 2 being held on a table of a milling machine and moved in a transverse direction while it is being machined. The inventive apparatus essentially consists of a rotatable magnetic arbour 4 surrounded by amagnetic coil 3 and an adjustable-currentDC power supply 5 that is connected to themagnetic coil 3. The apparatus further comprisesroller balls 1 "sticking" to the magnetic arbour 4 and performing the machining action, and anoil feed nozzle 6. During the machining operation theroller balls 1 are pressed against the outer surface of theworkpiece 2 by the collective action of the tapered-end magnetic arbour 4 and themagnetic coil 3, and rotate with the same rpm n as the magnetic arbour 4 along the surface of theworkpiece 2, providing rolling action. Theroller balls 1 are disposed in seats formed in the conically shaped (tapering) surface of the magnetic arbour 4. The number and size of theroller balls 1 depend on the size and degree of complexity of the surface to be machined. For extended surfaces it is recommended to use a greater number of bigger-sized balls, whereas for complex surfaces fewer and smaller-diameter roller balls 1 may be applied. When roller-burnishing complex spatial surfaces, the magnetic arbour 4, being held in the main spindle of a CNC-machine tool, can track the surface (in a manner similar to the cutter of a milling machine), with the distance between the end of the magnetic arbour 4 and the surface of theworkpiece 2 being kept at a minimum in order to minimize magnetic resistance. During the machining operation oil is fed from anozzle 6 to the working zone in a minimal quantity by means of high-pressurized air, reducing friction and with the oil spray removing material that may have chipped off the surface. Theroller balls 1 are preferably hard, magnetisable, polished-surface bearing balls that are coated with TiC-TiN coating to increase abrasion resistance. The non-magnetisable micrometer-thick coating also reduces the adhesivity of magnetisable contaminants, making more effective the operation of thenozzle 6. -
Fig. 2 shows the sectional view of another embodiment of the inventive apparatus. This embodiment contains apermanent magnet 12. - The
permanent magnet 12 is disposed inside atubular extension piece 11 made of non-magnetisable material, together with a connecting piece 9 that is connected to a rotatingarbour 8 located above thepermanent magnet 12. Bores are disposed in the skirt surface of thetubular extension piece 11 near the end thereof that is proximate to the connecting piece 9, with fasteningscrews 10 being disposed in the bores securing thetubular extension piece 11 to the connecting piece 9. - The connecting piece 9 and the
arbour 8 are connected with detachable or undetachable connection.Fig. 2 shows an embodiment with detachable connection. Theroller balls 1 "stick" to thepermanent magnet 12 and to thetubular extension piece 11 by virtue of the magnetic force exerted by thepermanent magnet 12. The apparatus illustrated inFig. 2 is placed during the machining operation above theworkpiece 2 movably attached to the table of a milling machine (not shown in the drawing) in such a way that theroller balls 1 touch the surface of theworkpiece 2. Thearbour 8, chucked on a driving apparatus not shown here, is rotated with an rpm n, while theworkpiece 2 is moved about the table of the mill in a transverse direction. The machining process of theworkpiece 2 is essentially the same as has been described above referring toFig. 1 . After the machining operation has been completed, the rotation of thearbour 8 and the movement of the table of the milling machine are stopped, and thearbour 8 is withdrawn by lifting it in a direction perpendicular to the plane of the table. Because of the application ofpermanent magnet 12 the magnetic force exerted onroller balls 1 remains there after the machine has been stopped, and thus theroller balls 1 remain "stuck" to thetubular extension piece 11 and to thepermanent magnet 12 and so they can be removed from theworkpiece 2 together with thearbour 8. - As it is shown in
Fig. 3 ,roller ball 1 effectively rolls back edge burrs that are about to come off the top surface of theworkpiece 2. -
Fig. 3 is a magnified view of a portion ofFig. 1 , showing unfinished (freshly milled), rolled-burnished and deburred surfaces. It can be easily seen that, due to the roller-burnishing action burrs either get torn off or are transferred to adjacent surface parts that are less important for the future operation of the machined piece, with the relatively rough surface produced by the tearing off of burr pieces by the first ball being roller-burnished by the next roller ball and the torn-off burr piece being removed by the high-pressure spray coming fromnozzle 6. -
Fig. 4 shows elements of an apparatus that is applied for roller-burnishing a cylindrical surface, at the stage when theroller balls 1, pressed against the surface bymagnetic jaws 7 that are moving in a direction parallel with the axis of theworkpiece 2, are rolling edge burrs produced at the edge located at the connection of the flat end surface and the cylindrical surface of theworkpiece 2. The apparatus can be mounted on a turning machine, themagnetic jaws 7 placed on the saddle can be magnetised by a uniform magnetic field, and theworkpiece 2 can be placed in a chuck and rotated with the desired speed, while contaminations that might be produced during roller-burnishing are removed by the high-pressure spray flowing fromnozzle 6 that contains a small quantity of oil conforming to the method of minimal-quantity lubrication. - Major advantages of the inventive roller-burnishing, deburring apparatuses are that they can be produced simply, can be adapted to be mounted on conventional machine tools, and can be easily operated.
- With the application of the method according to the invention the surfaces and burred edges of machine parts can undergo a single-stage roller-burnishing operation, which increases productivity and reduces per unit costs, while also reducing the environmental load of the operation due to minimal-quantity lubrication used in the inventive method.
