Definitions
- the present application relates to a tool according to the Preamble of claim 1.
- Disc grinding tools known. With these tools is the tool axis of rotation perpendicular to the machining surface aligned and the tool points to its the Machining area facing side circular respectively. ring-shaped abrasives. The grinding tool is then, for example, in circular paths over the Machining area led to a very homogeneous Micrograph leads. There are a large number for this type of tool various abrasives known, such as flat grinding wheels, bristle arrangements etc.
- the Grinding lamellas are regularly separated from one another spaced in the body.
- the grinding flaps have a layer on one side Abrasives.
- the object of the present invention was now to such a disc grinding tool with grinding flaps find which is already at the beginning of the operation, i.e. in the running-in phase, creates a constant micrograph and where there is a risk of damage to the grinding flaps is reduced or avoided.
- a profile of the to be processed Surface of the abrasive flaps coming into contact is specified at the very beginning of the deployment of the Tools, in the running-in phase, one of the later ones Processing phase corresponding grinding pattern generated.
- the corners of the grinding flap edges are rounded, the risk of tearing out is reduced the sharp edges compared to the conventional ones Tools considerably. They also have according to the invention designed tools, respectively. Slats, better Properties for machining fibrous Surfaces such as wood on which conventional tools due to the sharp edges scratches in cause the surface.
- the inventive New grinding tools directly for processing of surfaces can be used without first Run-in phase must be switched on, or with a different processing quality of the surfaces must be expected. With that and thanks to the diminished The risk according to the invention can be damaged Use tools more economically than the known ones Tools.
- the side view is conventional known disc grinding tool 1 with grinding flaps 2 shown.
- the grinding flaps 2 are radial with respect the grinding tool axis 3, perpendicular to the tool body 4 arranged upright.
- To keep a constant distance between the individual grinding flaps 2 are to be guaranteed between the grinding lamellae 2 spacer elements 5 from one elastic material arranged.
- This and the following are Figures on the right half of the figure only one Grinding flap 2 is shown.
- the grinding flaps 2 conventionally have shown a rectangular shape.
- FIG 3 is now the side view of an inventive configured grinding tool 1 shown.
- the structure of the grinding tool 1 basically corresponds with grinding lamellae 2 and spacers 5 the des conventional grinding tool 1 of Figure 1.
- Die Grinding flaps 2 now have a different basic shape on by the free edge 6 of the grinding flap 2 in one Angle ⁇ inwards against the grinding tool axis 3 is inclined.
- the trained according to the invention Grinding tool 1 accordingly has a concave, when new formed by the edges 6 of the grinding flaps 2 Processing area. If this grinding tool 1 is now in Is put into operation, i.e. at the appropriate speed is driven about the tool axis of rotation 3, the free ends of the grinding flaps 2 and thus the edge 6 slightly shifted radially outwards by centrifugal force.
- the edge 6 is almost parallel to the processing area, i.e. it becomes an im in operation essentially flat working surface.
- FIG. 4 shows a further preferred embodiment of Abrasive flaps 2 shown.
- these curves prevent that through a pointed edge in the to be machined Surface scratches occur, which is particularly the case with fibrous or soft surfaces such as wood that can occur and, on the other hand, reduce the risk of that the sharp corner breaks out and with it either that Grinding tool 1 or the surface to be machined is damaged.
- FIG Embodiment for a grinding flap 2 shown Another preferred is shown in FIG Embodiment for a grinding flap 2 shown.
- the entire free edge 6 of the grinding flap 2 designed profiled, especially wavy here. This design supports the described beneficial effects further.
- Plastic fibers are used, which lead to a Fabric as a carrier for the one arranged on one side Abrasives are processed.
- the fabric structure will preferably used in such a way that the warp and weft of the Are oriented so that the through the Centrifugal force caused the grinding flaps 2 to bend Consideration of the angle ⁇ optimally counteracted becomes.
