The quality of the table saw surface (or "bed") is extremely important to the overall performance of the machine. The table surface needs to be reliably flat and rigid to properly support the workpiece during a cut. As one of the most massive parts of the saw, the table surface also plays a major role in absorbing vibration. Because of the need for mass, rigidity and flatness, cast iron is the material of choice for the top of a table saw. On a quality saw, the table is made using a hefty quantity of cast iron and state-of-the-art foundry methods. The end result of the casting process is then precision ground to flatness in the .0005'' tolerance range.
Another important safety device is the magnetic switch. This device protects you after an electrical power failure. If the power fails and you have a regular switch, the saw will come back on when the power comes back on. If you were to be near the blade at the time, this could be disastrous. A magnetic switch will not allow the saw to start again until you press the button. The location of the switch is also important. It should be right out front where it can be quickly accessed by a hand, foot or knee in the event of an emergency. The off button should be wide, red in color and should extend outside of the switch box like a mushroom for fast access.
Some shops are small enough to require that all machines be able to roll around on the floor. The theory is that you pull out only the machine you are using at the time. In planning your shop, you should decide if your space requirements will mean that everything has to roll, some machines but not others have to roll or all machines can remain in their own positions permanently. Many cabinet saws offer the optional extra of some sort of mobility device. In the case of a table saw, you don't want it rolling around while you are pushing lumber through it and so the wheels must retract enabling the saw to rest on its cabinet base on the floor.
A table saw is a woodworking instrument that has spherical saw blade, escalated on the arbor, which functions with the use of an electric motor. The sharp edge extends beyond the facade of a table that serves as a hold for the materials being cut. It works well with cabinets such as filing cabinet and dresser, same as with furniture with plane parts. This is mostly, helpful when you would want to maximize your place at home or at the office and you can't afford to have long pieces and bulky furnishings.
At least one, but preferably two or more access doors should be provided leading into the cabinet of the table saw. The one you will use most often will be for cleaning out the interior of sawdust. Another should give easy access to the motor, trunnion and belts for adjustment and repair. Many saws provide a removable access panel instead of a second door. That's fine for occasional motor, arbor, belt and trunnion access but you will want the sawdust door to open and close easily.
