Woodworking machines with overmolded arbors
Power equipment with various safety systems is disclosed. Table saws with safety systems and/or blade retraction are disclosed. Over-molded arbors are disclosed, including arbors with prepreg over-molding. An electrically non-conductive material may be disposed to electrically insulate the arbor. The electrically non-conductive material may be made from fiber organized into a pattern.
1. A woodworking machine comprising:
a cutter;
an arbor on which the cutter is mounted;
an electrically non-conductive material over-molded on at least a portion of the arbor to electrically insulate the arbor, where the material comprises fiber organized into a pattern;
a detection system adapted to detect a dangerous condition between a user and the cutter; and
a reaction system adapted to perform a specified action to mitigate the dangerous condition upon detection of the dangerous condition by the detection system.
2. The woodworking machine of claim 1 where the detection system imparts an electrical signal on the arbor.
3. The woodworking machine of claim 1 where the material comprises prepreg.
4. The woodworking machine of claim 3 where the prepreg includes resin impregnated glass fiber cloth.
5. The woodworking machine of claim 4 where the resin is epoxy.
6. The woodworking machine of claim 1 where the material is a thermoset.
7. The woodworking machine of claim 1 where the material is fiberglass.
8. The woodworking machine of claim 1 where the material comprises a fabric wrapped a plurality of times around at least a portion of the arbor and hardened resin.
9. The woodworking machine of claim 1 where at least a portion of the arbor under the material has a non-smooth surface.
10. The woodworking machine of claim 1 where at least a portion of the arbor under the material is roughened.
11. The woodworking machine of claim 1 where at least a portion of the arbor under the material is patterned.
12. The woodworking machine of claim 1 where the woodworking machine includes a bearing to support the arbor and where the material provides a bearing seat for the bearing.
