Definitions

  • the invention relates to a method for profiling the circumference of a workpiece, in particular for producing an Archimedean relief grinding curve on a milling cutter or tap.
  • the invention is based on the task of generating a predetermined geometric shape with a complicated course, such as an Archimedean relief grinding curve on milling cutters and drills, with the highest possible machining speed with high contour accuracy and surface quality.
  • a complicated course such as an Archimedean relief grinding curve on milling cutters and drills
  • the translatory movement cycles are eliminated during the grinding process, as a result of which grinding speeds of 60 m / s and higher are made possible.
  • the use of electronic gears also enables the coupling and uncoupling of axes assigned to one another without the interdependency relationships being lost. As a result, the roughing or power grinding and the finishing or quality grinding can be carried out under the optimal conditions and with high accuracy.
  • the grinding wheel 1 is provided on its periphery with the relief grinding curve adapted to the workpiece 2 to be ground (tap).
  • the relief grinding curve of the grinding wheel 1 is generated by the diamond dressing roller 3.
  • the diamond dressing roller 3 is brought into the desired position in relation to the rotating grinding wheel by means of appropriate drives, the synchronous operation being ensured by an electronic control.
  • the respective stroke movement H of the dressing roller 3 corresponds to the convex relief curve desired on the circumference of the grinding wheel.
  • the relief grinding curve can be mapped once or several times on the circumference of the grinding wheel. In Fig. 1 the 2-time figure is indicated, while the tap has four relief grinding curves over its circumference.
  • the dressing roller 3 executes a lifting movement in addition to the rotor movement.
  • the grinding wheel 1 and the workpiece 2 rotate synchronously about the fixed axes of rotation 4 and 5, and the grinding wheel 1 executes a relative movement to the workpiece axis due to the convex profile of its circumference.
  • ⁇ 1 a safety area is indicated, while ⁇ 2 indicates the safety area including the grinding section and ⁇ 3 including the groove section. In the grooved section, the relief curve is returned to the starting point A S.
  • a first step (rough grinding), the thread is now ground into the workpiece 2.
  • the relief grinding does not have to be done yet.
  • the motors M1 and M2 for workpiece movement and M8, M3 for the grinding wheel movement as well as the associated sensors WM1, WM2, WM8 and WM3 are now also in a defined relationship brought.
  • M1 and M2 When dressing the grinding wheel and grinding the workpiece, the M5 and M8 motors must also be in synchronization with M1 and M2 and the M4 motor must be activated.
  • the grinding wheel can be dressed using the diamond dressing roller after or during rough grinding.
  • the thread is finish-ground in a further operation by finish grinding with the single or multi-start grinding wheel including relief grinding.
  • the motors M2, M1, M3 and M8 and the assigned sensors are brought into a defined relationship and there is synchronization between the motors M1, M2 and M8.
  • the workpiece After finishing grinding, the workpiece is changed, and the rough grinding of the new workpiece can be carried out essentially without a previous dressing process.
