Claims
- 1. Method for machining a workpiece, whereby chips are removed from the workpiece, comprising the following:
introducing a lubricant in a flowable state into at least one recess of the workpiece; solidifying the lubricant in the recess; machining the workpiece, whereby chips are removed from the workpiece, with at least one machining tool coming into direct contact with the lubricant and being lubricated by the lubricant, and the lubricant transforming from a solid to a liquid state during machining of the workpiece by the machining tool; transforming the lubricant remaining in the recess of the workpiece into a flowable state and removing the lubricant from the workpiece.
- 2. Method in accordance with claim 1, wherein the lubricant is introduced in the molten state into the recess of the workpiece.
- 3. Method in accordance with claim 1, wherein a lubricant whose solidification point is higher than approximately 60° C. is used.
- 4. Method in accordance with claim 1, wherein a lubricant which comprises a wax is used.
- 5. Method in accordance with claim 1, wherein the at least one recess comprises an opening for introduction of the lubricant and at least one further access opening which is closed by a closure element during introduction of the lubricant.
- 6. Method in accordance with claim 5, wherein the closure element is removed from the workpiece prior to machining of the workpiece.
- 7. Method in accordance with claim 5, wherein the closure element remains on the workpiece during machining of the workpiece.
- 8. Method in accordance with claim 1, wherein prior to machining of the workpiece, a portion of the lubricant is introduced into a recess of the workpiece, which is not machined during machining of the workpiece.
- 9. Method in accordance with claim 1, wherein the lubricant is introduced into the at least one recess of the workpiece in a lubricant filler station,
the workpiece is subsequently conveyed to a machining station, the workpiece is subsequently machined in the machining station, whereby chips are removed from the workpiece, the workpiece is subsequently conveyed to a lubricant recovery station, and the lubricant remaining in the workpiece is subsequently removed from the workpiece in the lubricant recovery station.
- 10. Method in accordance with claim 1, wherein the lubricant is removed from the workpiece by the workpiece being heated and rotated during the heating or rotated after the heating or rotated both during and after the heating.
- 11. Method in accordance with claim 10, wherein the workpiece is heated by being subjected to a heated fluid.
- 12. Method in accordance with claim 1, wherein a lubricant whose solidification point is higher than approximately 65° C., is used.
- 13. Method in accordance with claim 1, wherein a lubricant which comprises a paraffin wax is used.
- 14. Method in accordance with claim 10, wherein the workpiece is heated by being subjected to heated air.
- 15. Method for machining a workpiece, whereby chips are removed from the workpiece, comprising the following:
introducing a lubricant in a flowable state into at least one recess of the workpiece; solidifying the lubricant in the recess; machining the workpiece, whereby chips are removed from the workpiece, with at least one machining tool coming into direct contact with the lubricant and being lubricated by the lubricant; transforming the lubricant remaining in the recess of the workpiece into a flowable state by melting the lubricant, and removing the lubricant from the workpiece.
- 16. Method for machining a workpiece, whereby chips are removed from the workpiece, comprising the following:
introducing a lubricant in a flowable state into at least one recess of the workpiece, which comprises an opening for introduction of the lubricant and at least one further access opening which is closed by a closure element during introduction of the lubricant; solidifying the lubricant in the recess; machining the workpiece, whereby chips are removed from the workpiece, with at least one machining tool coming into direct contact with the lubricant and being lubricated by the lubricant; transforming the lubricant remaining in the recess of the workpiece into a flowable state and removing the lubricant from the workpiece.
- 17. Apparatus for machining a workpiece, whereby chips are removed from the workpiece, comprising:
a filler device for introducing a lubricant in a flowable state into at least one recess of the workpiece; at least one machining tool for machining the workpiece, whereby chips are removed from the workpiece, with the machining tool coming into direct contact with the lubricant during the machining and being lubricated by the lubricant, and with the lubricant transforming from a solid to a liquid state during machining of the workpiece by the machining tool; and a device for transforming the lubricant remaining in the workpiece into a flowable state and removing the lubricant from the workpiece.
- 18. Apparatus for machining a workpiece, whereby chips are removed from the workpiece, comprising:
a filler device for introducing a lubricant in a flowable state into at least one recess of the workpiece; at least one machining tool for machining the workpiece, whereby chips are removed from the workpiece, with the machining tool coming into direct contact with the lubricant during the machining and being lubricated by the lubricant; and a device for transforming the lubricant remaining in the workpiece into a flowable state by melting the lubricant and for removing the lubricant from the workpiece.
- 19. Apparatus for machining a workpiece, whereby chips are removed from the workpiece, comprising:
a filler device for introducing a lubricant in a flowable state into at least one recess of the workpiece; a closure element for closing an access opening of the recess in the workpiece during introduction of the lubricant through an opening in the recess for introduction of the lubricant; at least one machining tool for machining the workpiece, whereby chips are removed from the workpiece, with the machining tool coming into direct contact with the lubricant during the machining and being lubricated by the lubricant; and a device for transforming the lubricant remaining in the workpiece into a flowable state and removing the lubricant from the workpiece.
