One table saw manufacturer I know believes in "aging" its cast iron machine table tops before milling them flat. The tops are cast and then left outside in a "bone yard" to bend, bow, warp and twist in the sun and rain for a year or so. Then, they are brought inside where all the rust is removed and the table top is ground absolutely flat and polished to sheen. The theory is that the metal needs to settle into a place where all post-casting movement has ceased and that the table should not be ground flat before this is done. Otherwise, the table may move out of absolute flatness after it is part of your new table saw and that it not at all desirable. Why? Because the flatness of your table saw top will determine the accuracy of your cuts. Be sure to check your new table saw for table flatness with a straightedge on or before delivery and afterwards from time to time. Lay the rule across the table top at all angles and check for daylight under the rule or rocking of the straightedge on the table top.
The bench top model is preferred for those who are looking for a table saw that is portable and less expensive; however, remember that you always get what you pay for. The bench top saw has the least amount of capability out of any of the table saws. With the decreased size and weight of the saw, it is less durable and there are greater restrictions of the size of projects one can do.
The bench top saw, also known as the portable saw, does not come all the way to the floor but is meant to be placed on top of a table for support. This is the more lightweight version of the table saws. They usually can be carried by one person from job to job.
In older table saw, altering the angle of the blade was used to increase or decrease the depth of the cut. Nowadays, there is still an adjustable angle control, but this is used merely to adjust the angle at which the material is cut, and is not used to decrease or increase the depth of cut being made.
Some saws shield the blade in a casing underneath the saw table and suck the dust out directly from there. Others slant the floor of the saw cabinet towards a dust collection port. Many just allow the sawdust to accumulate on the floor under the saw until you clean it out. You will always have some cleaning of the interior to do. Perhaps you won't wait until the sawdust has totally encased the trunnion gears packing itself up to the bottom of the table top. You will need to connect the saw to a dust collector through its dust port. The suction of the dust collector should be about 350 CFM for a 10" saw and more for a larger saw.
