For straight-line cutting of all types of wood and paneling, the bench-top saw is undoubtedly the most accurate --
Most widely used-
All fixed machine tools.
The circular saw is made up of rotating blades that extend upwards through the slots on the metal table, enabling the family handyman to perform extensive cutting, oblique cutting and cutting (grooving)
Easy operation-
And accurate.
Simplified cutting blade (
When the blade is cut at an angle other than 90 degrees angle to the surface)
The saw is designed to tilt the blade or table.
The inclined table model is cheaper than the inclined blade;
But the tilting blade model (
Commonly referred to as the tilt blade saw)
It\'s much easier to use.
The work is always flat on a permanent level table, so that when sliding the panels and boards to the table, it is easier to keep them in place.
An important safety feature is that the blade can be raised or lowered so that the height of its extension is enough to complete the work.
On the sloping table model, it is the table that rises or falls.
On the tilted knife-bar model, the blade rises or decreases when the table remains stationary.
This ability to adjust the height of the blade is particularly valuable in the operation of the saw cutting only halfway through the work and many slotting and polishing operations (
The saw blade is replaced by a series of special cutting tools or worn surface disks).
The saw is usually rated according to the size of the blade it holds.
Therefore, the 8-inch saw is a saw with a diameter of 8.
The 10 inch saw needs a 10-inch blade.
The most popular sizes in the home workshop are 8 and 10-inch models.
For the sake of safety, most table saws are equipped with combined advertis and saw shields.
The shield can be made of metal or plastic and is designed to slide down from the top of the blade when cutting to cover exposed teeth. (
In the photo above, this guard was deliberately eliminated so that the cutting action can be seen more clearly. )
Splitter consists of vertical metal plates directly aligned with the saw blade.
When the wood slides past, the saw cut or slot is kept open so that the wood does not combine or \"catch\" on the teeth of the saw \".
Cross-domain or re-advertising (
Saw with grain)
It is the two most common operations using a circular saw.
In order to facilitate accurate cross cutting at any angle, a cross cutting guide including the oblique cutting gauge is provided.
This slides in the groove of the saw stand, feeding the workpiece into the blade.
While steadily advancing the work, the work is closely tied to this gauge.
For tear cutting, the Mitter gauge will be removed and the tear guide will be installed.
This includes a long metal fence that extends the length of the table.
It can move back and forth at different distances from the saw blade, and once the initial adjustment is made, it is designed to always be parallel to the saw blade.
When an edge is firmly in contact with this torn fence, the work is carried out through the saw blade.
When cross cutting, as mentioned above, hold the work firmly with one hand.
In order to minimize the movement or shaking of long parts, the auxiliary wooden fence can be fixed on the surface of the gauge to provide additional support for the work when moving forward.
Care must be taken to hold the work firmly, and the handyman never tries to catch or touch the cut-off end until the saw blade stops spinning.
When tearing the long plate into a narrow width, the fingers usually have to be very close to the saw blade --
If a person\'s hand is used to push the work through the blade.
To prevent this, the work should move forward until the end of the board.
A few inches away from the saw blade.
At this point, the putter should be used instead of the finger to push the rest of the board.
This putter is just a piece of waste wood with a gap at one end, as shown in the picture above.
When operating this power saw, the handyman should make sure that the blade is adjusted so that no more than 1/4 inch above the work to achieve maximum safety.
All tear operations should use the split ripping guide and should not wear a tie or other loose clothes at any time.
The sleeves should be rolled up or buckled at the wrist.
A version of the file was printed on page X23 of The New York edition on August 30, 1964 with the title: Saw;
Machine tools are good at precise cutting.
