Abstract
Improved table saws and table saws designed to implement safety systems that detect contact between a person and a dangerous portion of the saw are disclosed. The table saws may include an elevation mechanism, a tilt mechanism, and an adjustment system configured to adjust the parallelism between a tilt axis and a blade. The elevation mechanism may include a vertical slide that includes two shafts, and the adjustment system may include a mechanism to adjust the parallelism of the two shafts.
Claims13
A table saw comprising:
- a table defining a work surface;
- a nominally planar, circular blade configured to extend at least partially above the work surface to cut a workpiece on the work surface;
- a motor to drive the blade;
- an elevation mechanism configured to position the blade at various elevations relative to the work surface;
- a tilt mechanism configured to lilt the blade at various angles relative to the work surface around a tilt axis;
- and
- an adjustment system configured to adjust the parallelism between the tilt axis and the plane of the blade.
