Definitions

  • the invention relates to a grinding machine for grinding circumference, clearance angles and protective chamfers in workpieces, preferably workpieces made of steel, hard metal, ceramic, cermet, CBN and PCD, the material processing by means of a, preferably roughly dish-shaped, grinding wheel takes place, and the workpiece in a, advantageously designed as a ram tensioning device, workpiece spindle is held during machining, wherein the grinding machine has at least four axes, of which at least two axes are formed as rotary axes and at least two axes as linear axes. In this case, the axes are usually aligned at least approximately orthogonally with respect to at least one other axis.
  • the disadvantage here is that only one workpiece can be processed simultaneously, whereby the efficiency of the grinding machine is limited.
  • the efficiency is also limited by the non-productive time due to the removal of a first workpiece after the processing and by attaching a subsequently machined workpiece before it is processed.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a grinding machine with which an improved use of the grinding wheel is made possible.
  • This object is achieved in a generic grinding machine in that at least one further, independently movable workpiece spindle is provided for the synchronous or asynchronous machining of at least two workpieces by the grinding wheel, wherein the Workpiece spindles are provided with respect to the grinding spindle in different relative positions, that the workpieces of the two workpiece spindles are machined simultaneously without collisions by the grinding wheel.
  • the workpiece spindles are provided with respect to the grinding spindle in different relative positions, that the workpieces of the two workpiece spindles are machined simultaneously without collisions by the grinding wheel.
  • the grinding spindle can be arranged stationary, and advantageously rigidly mounted, and the required relative movements between grinding wheel and the respective workpiece are realized by a displacement of the corresponding workpiece spindle.
  • the grinding wheel may be formed as a face grinding wheel or a peripheral grinding wheel or a combination thereof, so that a variety of grinding tasks can be handled easily.
  • At least two workpiece spindles can be provided, each of which is each provided on a separate turntable, each of these turntables in turn being arranged on a separate, advantageously designed as a linear slide, displacement device.
  • a plurality of linear slides can be arranged on a common linear guide.
  • a turntable is understood to mean a rotary displacement device whose axis of rotation is aligned orthogonally to the axis of rotation of the grinding wheel and orthogonally to the displacement device of the respective guide carriage.
  • at least one turntable and / or at least one linear slide may be preferably CNC-controlled, wherein a common control or a separate Control can be given.
  • one turntable may be controllable in a range of about -100 ° to about + 45 °
  • another turntable may be controllable in a range of about -45 ° to about + 100 °, for example.
  • At least two displacement devices can be formed as linear slides, which are arranged on separate linear guides or on a common linear guide.
  • the linear slides may in each case in each case be arranged on a linear guide, which is provided on a displacement device likewise designed as a (further) linear slide, which are arranged on separate (further) linear guides or on a common (further) linear guide.
  • two workpiece spindles may be provided aligned in opposite directions, wherein the two workpiece spindles are completely or at least substantially mirror-inverted and are each arranged away from each other with their larger projection away from each other. If one looks from the front onto the grinding wheel, thus, for example, a first workpiece spindle can be provided at the "3 o'clock” position, with its larger drive side being provided pointing to the right. On the other hand, a second work spindle may be provided at the "9 o'clock" position, with its larger drive side provided to the left.
  • At least two workpiece spindles may be formed at least partially, preferably completely, identically and / or at least two workpiece spindles may be at least partially, preferably completely, mirror-inverted.
  • two workpiece spindles can each be equipped with different, different machining operations also of identical workpieces enabling clamping systems, so that simultaneously different steps can be carried out.
  • machining of the edge of a workpiece on the first workpiece spindle and machining of the chipbreaker in a vertical clamping on the second workpiece spindle can take place.
  • At least one workpiece spindle can be equipped with a measuring system, and preferably both workpiece spindle can be equipped with separate measuring systems.
  • a measuring system preferably both workpiece spindle can be equipped with separate measuring systems.
  • At least two synchronously or asynchronously controllable systems for dressing and / or pressing the grinding wheel can be assigned, so that the corresponding processing of the grinding wheel are possible independently and without corresponding non-productive times.
  • At least one handling or robotic system may be provided for loading and / or unloading at least one workpiece spindle, preferably for loading and / or unloading at least two or all workpiece spindles, so that the loading or unloading can take place from one spindle during the other workpiece spindle is used for grinding a workpiece.
  • At least one workpiece spindle can be removable and exchangeable with another device for different mechanical machining operations.
  • at least one workpiece spindle not removable and thus not be exchanged for another device for different mechanical machining operations.
  • a third CNC-controlled axis of rotation between the workpiece spindle and the turntable be mounted, which may be preferably aligned orthogonal to the axis of rotation of the turntable and the axis of rotation of the workpiece spindle.
  • the workpiece spindles can be movable with their respective axes depending on each other.
  • z. B. only one workpiece spindle be equipped with a measuring system and serve as a "master” for another, designed as a "slave” workpiece spindle.
  • FIGURE shows a grinding machine 1 for grinding workpieces 2, wherein the material processing takes place by means of an approximately bowl-shaped grinding wheel 3.
  • two independently movable workpiece spindles 4 are provided for the synchronous or asynchronous machining of at least two workpieces 2 by the grinding wheel 3.
  • the workpiece spindles 4 are provided in different relative positions relative to the grinding wheel 3 (as well as the grinding spindle not shown in the figure) such that the workpieces 2 of the two workpiece spindles 4 can be processed simultaneously without collisions by the grinding wheel 3.
  • the grinding wheel 3 (as well as the grinding spindle not shown in the figure) is arranged stationary and rigidly mounted.
  • the required relative to the machining of the workpiece 2 relative movements between the grinding wheel 3 and the respective workpiece 2 are realized by a displacement of the corresponding workpiece spindle 4.
  • the two workpiece spindles 4 are each provided on a separate turntable 5, wherein each of these turntables 5 in turn each on a separate, designed as a linear slide 6 displacement device is arranged.
  • the two linear slides 6 are in turn each arranged on a linear guide 8, which is provided in each case on a likewise designed as a linear slide 7 displacement device.
  • the orientation of the linear guides 8 and thus the displacement direction of the linear slide 6 is in each case aligned parallel to the axis of rotation of the grinding wheel 3.
  • the two linear slides 7 are in turn arranged on a common linear guide 9.
  • the orientation of the linear guide 9 and thus the displacement direction of the linear slide 7 is aligned orthogonal to the orientation of the displacement direction of the linear slide 6.
  • the respective axis of rotation of the turntables 5 is oriented in each case orthogonal to the axis of rotation of the grinding wheel 3 and orthogonal to the displacement direction of the respective linear slide 6 and orthogonal to the displacement direction of the respective linear slide 7.
  • the turntable 5 shown in the figure on the left may be controllable in a range of about -100 ° to about + 45 °
