Definitions
- Milling device for milling out a pocket-shaped recess in a furniture panel to accommodate a furniture fitting
- the present invention relates to a milling device for milling out a pocket-shaped recess in a furniture panel for receiving a furniture fitting, comprising:
- the at least one chain cutter has at least one chain guide, on which at least one cutter chain is arranged circumferentially with a predetermined pretension.
- WO 2020/232484 A1 shows a furniture drive for moving furniture flaps, the housing of the furniture drive being designed to be accommodated in a mounted state within a recess in a furniture panel.
- the recess is designed in the form of a blind hole, with the housing of the furniture drive being accommodated completely within the blind hole and completely within a material thickness of the furniture panel in an assembled state.
- a compact arrangement of the furniture drive is possible, with the space available inside the furniture body not being restricted.
- the furniture drive is hardly noticeable in an assembled state, an overall visual impression can also be improved. For example, a visually appealing, uniform and intact surface finish of the furniture board can be made possible on its inside and outside.
- the production of the recess in the furniture board is associated with a number of challenges.
- the object of the present invention is to specify a milling device of the type mentioned at the outset while avoiding the disadvantages mentioned above, the number of manual clamping processes being able to be at least reduced.
- the milling device has at least one compensation device, by means of which a deviation of the pretensioning of the milling chain from the predetermined pretensioning can be at least partially, preferably completely, compensated.
- the milling device has a compensation device which automatically corrects the pretensioning of the milling chain to a predetermined pretensioning during operation.
- This has the particular advantage that wear-related or temperature-related changes in the Bias of the milling chain are at least partially compensated. The manual loosening of the milling chain after it has cooled down can also be omitted.
- the compensation device has at least one, preferably rotatable, deflection element, which can be placed against an inside of the milling chain and which can be pressed against the inside of the milling chain by at least one spring element, so that a track of the milling chain can be enlarged.
- a variable pretensioning force can thus be generated by the at least one spring element, which force always keeps the milling chain with the predetermined pretension.
