Definitions

the invention relates to a method and a device for dressing grinding wheels with profiled Work surface by means of a dressing roller, in which one Grinding wheel and dressing roller, the surface with Material of higher hardness than that of the dressing Grinding wheel is occupied, with the same peripheral speed can circulate and with high pressure compresses.
the diamond-set disc was subject to only one very little wear, which only came about that the contact between the grinding wheel and the Dressing roll was not punctiform, but on one radial line took place. Because the diamond coverage extended itself on both sides and across the peripheral surface the dressing roller rounded on its surface. As for the destruction of the binder bridges forces to be exerted on the wheel to be dressed the diamond-set dressing rollers were very high however, should be quite thin in order to get fine curves of the It turned out to be possible to edit the cross-section of the pane through the constant appearance of side forces Difficulties.
the diamond-set dressing rollers needed lateral support with a shorter radial Extension in the form of hard metal disks, which however the geometrical scope due to its dimensions and thus restricted the possible applications.
Disc-shaped diamond tools with a diamond coating an end face of a hard metal disc or between two faces of hard metal discs are from the EP 0 410 481 became known. Your area of application is that Grinding workpieces.
the invention avoids the disadvantages of the prior art Technology. It is the object of the invention with simple Means create a way of abrasion in the process of crushing mentioned at the beginning different surface speeds between Avoid grinding wheel and dressing roller and thereby to achieve long service life of the dressing tool.
the invention is that as a dressing roller used a circular flat carbide disc, the one face just covered with diamond material, that one grinding wheel and dressing roller to each other that between grinding wheel and dressing roller just an almost punctiform touch takes place and that the contact pressure between Select grinding wheel and dressing roller so high that on Point of contact the binder bridges between the break individual grinding wheels of the grinding wheel.
the punctiform contact ensures that the Contact forces do not need to be as high as in flat touch. That is also the reason why the necessary reaction forces due to the thin diamond coating be picked up without damage when pressed can.
This setting on point contact is turned on by the dressing roller determined the currently processed surface of the appropriate grinding wheel to be dressed reached angle. This can be automated by a control device respectively.
the targets are set up for crash use by making a hole centrally in these disks cuts to get a washer that one can then clamp in the tool holder.
the one with this Process step waste namely a Circular disc with a smaller diameter can be used for the Continue to use the stock of cutter bars and these Circular disc with a smaller diameter also in Split pieces.
the production of a dressing roll for the implementation is expediently carried out by placing it in a circular hard metal disc, one end for other purposes is just covered with diamond material, centrally a hole incorporated, and introduces a mandrel in this hole.
a device for dressing grinding wheels with profiled work surface consisting of a holder for the dressing Grinding wheel, a holder for the dressing roller and a drive device and a press device, through which the dressing roller and the Grinding wheel are pressed together
the dressing roller is a hard metal disc, one end face with polycrystalline diamond material is just coated and in which is a central hole that the Carbide disc is accommodated in a receptacle, which holds the carbide disc in one position which is just a point contact between the Carbide wheel and the grinding wheel to be dressed takes place and that the pressing device for a contact pressure designed between grinding wheel and dressing roller is so high that it is at the point of contact the binder bridges between the individual Break the grinding wheels of the grinding wheel.
This device can be made more effective that the layer thickness of the diamond coating of the dressing roller is reduced by electroerosion.
This device can have a particularly long life if the rotary movement of the dressing roller from the Rotational movement of the grinding wheel is derived.
This device can be used very effectively if the dressing roller on the diamond material Face a larger diameter than on the opposite side.
the desired punctiform touch of to be dressed Grinding wheels and dressing roller can be used with this Always adjust the device when the angle of attack the inclusion of the dressing roller is changeable.
the diamond coating is preferably a polycrystalline Layer.
PCD polycrystalline diamond discs
the dressing roller consists of a hard metal disc 1, which is coated on one side with diamond material 2.
the dressing roller has a hole 3 in the center, in order to Bracket for their rotatable storage can be clamped to be able to.
the Diameter of the dressing roller in the direction of the End face carrying diamond material can be fillets and the like Dress the shapes on the grinding wheel 4.
the PCD coating on the hard metal disc can be fixed on the hard metal carrier during the manufacturing process or can be applied as a thin layer using the CVD process.
the relative speed between diamond grinding wheel and diamond crushing roller is zero when these two roll on each other, rarely is it exactly zero due to the slip.
a great advantage of this "round design" according to the invention is the fact that the diameter can definitely decrease due to wear and the tool can still be used (eg centerless grinding, the crushing roller only has to be adjusted radially). The control therefore does not need to be adjusted in the axial direction according to the wear of the tool, but only radially. This leads to the possibility of using much simpler controls.
