Definitions
- the invention relates to a dressing roller for grinding wheels according to the claim 1.
- dressing is the fine machining of a rotating grinding wheel Understood.
- the purpose is to manufacture or restore the surface geometry and / or the grinding ability of the coating of the grinding body or tool.
- Grinding tools the coating of which has hard material grains or CBN (boron nitrite) grains, are mostly machined with diamond-coated dressing tools.
- CBN boron nitrite
- a disadvantage of such dressing rollers is that the minimum radius that can be achieved is relatively large. It is therefore difficult to dress grinding wheel profiles with small radii satisfactorily. In principle, this could also be done with a single diamond become. However, single diamonds wear out relatively quickly. The frequent replacement the single diamond in the body causes a lot of time.
- gear wheels are not made with precisely dressed grinding wheel geometries the required geometric shape is ground on the gear profile not reached. Additional vibrations can develop, which are undesirable Noise in the gearbox can cause teeth to break.
- the grinding achievable precision naturally depends on the precise grinding surface and this in turn from a suitable dressing tool.
- the invention has for its object a dressing roller containing diamonds to create, in particular for dressing CBN grinding wheels that have a high Tool life is suitable for working very small radii and with the Covering surfaces can be precisely finished.
- the dressing roller according to the invention consists of at least three parts, namely a circular disk, which has radial receiving slots on the circumference, elongated diamonds that are received in the receiving slots and at least one support disc on at least one side of the receiving disc.
- Monocrystalline (MKD) or polycrystalline (PKD) diamonds come as diamonds into consideration, which are then inserted into the receiving slots.
- the Diamonds are preferably designed to be pinched from the receiving slots be included.
- the dimensions of the diamonds are one certain tolerance range. By appropriate selection it is achieved that of the receiving slots can be received by clamping. Better adaptation to that Tolerances of the diamonds can be obtained by dividing them into Clearances on the circumference of the disks between adjacent receiving slots radial compensation slots are formed, which with an excess of diamonds allow the intermediate segments to yield. With the help of the compensation slots the occurring tolerances e.g. with rod-shaped Diamonds to be caught.
- the attachment of Holes in the area of the compensation slots which receive screws with which the segments adjacent to the compensation slot move more or less apart can be used to generate a clamping force on the in the receiving slots inserted diamond.
- the diamonds are cut at the outer end so that a predetermined one Geometry, e.g. Radius can be obtained. So that a small radius is used , it is advantageous if the support disc is close to the diamond in axial Direction has only very small dimensions, preferably is conical, so that a very acute angle can be obtained. With the help of such Dressing roller it is therefore possible to dress predetermined radii on grinding tools.
- Geometry e.g. Radius
- the diamonds are mechanically attached, so they can be replaced if this is necessary.
- Through a variety of single diamonds on the scope of the Dressing rollers increase the service life compared to e.g. a single diamond significantly.
- the lifespan of the dressing roller can be reground frequently extend.
- the dressing roller Due to the structure of the dressing roller (modular structure of the individual parts) produce the dressing rolls reproducibly and precisely.
- the individual parts can be prefabricated become.
- the individual diamonds are mechanically in the receiving slots curious; excited.
- One embodiment provides for improvement of the uniform clamping the invention that the receiving slots extended radially inward Have sections whose width is preferably less than that of the receiving slots, whereby bendable between the receiving slots in the plane of the disc Segments are formed.
- the segments are preferably shaped so that in the event of a bend, the surfaces of the receiving slots, each of which is a diamond clamp, be moved approximately parallel to yourself, so that independent an approximately flat clamping is guaranteed by the degree of clamping.
- a better bendability is obtained if the inner ends of the elongated Slit sections open into a hole.
- the elongated slot sections extended slot areas can be provided. In this e.g. the top of one Screwdriver are inserted to bend the adjacent segments apart. This enables a diamond to be removed and inserted.
- the support disks are preferably tapered at the edge, preferably with a very small angle on the circumference.
- the support disks preferably consist of a hard material that can be ground together with the diamonds. The Grinding the diamonds requires a special grinding surface, e.g. for support washers steel would smear the material.
- a hard metal, Cermet, ceramics or a steel coated with a hard material Preferably a hard metal, Cermet, ceramics or a steel coated with a hard material. This material also has the advantage of being subjected to a corresponding load Diamonds to be flexurally stable.
- the receiving disc and the at least one support disc are axially against each other clamped, preferably by a suitable screw connection. Because of the Thickness of diamonds also tolerances, it is advantageous if after an embodiment of the invention, a leveling layer between the receiving disc and the support disc is provided.
- the compensation layer can be made of plastic, a casting alloy, a solder alloy pulp, galvanically deposited Metal or the like exist. Become two or more recording disks A compensating layer can be clamped between two almost identical supporting discs can also be arranged between the pick-up disks.
