摘要： A table saw includes a base, a work table having a cutting opening, a tank for receiving cooling liquid, a blade partly extending out from the cutting opening, and a guard assembly. The guard assembly includes a guard for covering the blade and for moving upwards under the action of a workpiece. In a working condition, at least a portion of the guard abuts against the workpiece, and the workpiece can slide relative to the guard. The guard has a guiding wall which abuts against the workpiece in the working condition and which guides the cooling liquid into a kerf in the workpiece formed by the blade. The table saw effectively controls the cooling liquid splashed during the cutting operation of the workpiece and prevents the cooling liquid from splashing to dirty the operator, the work table, and the workpiece.

摘要： A safety system is provided for a power tool having a motor-driven cutting blade, a safety mechanism operable by a controller to stop and/or move the cutting blade and a blade guard. The safety system includes an electrically active surface provided on the blade guard that is configured to change an electrical characteristic in response to contact between the body of an operator and the active surface. An active surface controller is operable to provide electrical power to the electrically active surface, to generate a signal in response to the change in the electrical characteristic, the signal indicative of an unsafe condition, and to transmit the signal to the controller for the safety mechanism.

摘要： Table saws are disclosed. The table saws can include a blade, an arbor, an arbor block, an elevation carriage, and a latch that connects the arbor block and the elevation carriage. The arbor block can have a first position in which the latch connects the arbor block and the elevation carriage, and a second position in which the latch does not connect the arbor block and the elevation carriage. The arbor block can pivot from the first position to the second position upon the occurrence of a retraction force. The table saw can include an actuator to cause the occurrence of the retraction force, and detection electronics to detect contact between the blade and a person. Woodworking machines with detection and reaction systems are also disclosed. A reaction system can include an explosive that causes retraction of a cutting tool.

摘要： Present invention teaches to build a woodworking table saw where, a splitter/riving knife move with the saw blade in a synchronized manner, with an idle gear engaging in planetary circular action around a fixed quadrant gear and the outer gear teeth portion of a support arm, so that any height adjustment or angle tilting done to the saw blade will result in the same movement of the splitter/riving knife, maintaining the constant linear difference (usually 5 mm) between the saw blade and the splitter/riving knife. In addition, to facilitate the installation, changeover, and/or removal of the splitter/riving knife, a spring pressure plate mechanism is used, along with lug bolts and a spring loaded secure pin device to easily set the splitter/riving knife in a pre-set position without using tools and in shorter time duration.
