What is a table saw?
A table saw or other cutting machine includes a conveying member substantially close to a flanged edge on the bottom surface of a worktable and a reversible extension support device. The supporting device includes a supporting member that can extend toward and away from the workbench in a horizontal direction. The dust turning skirt plate extends into the dust receiving cavity from the lower surface of the workbench. The anti-reverse spacer is a sealed-end rivet, which is installed at the middle position of the anti-reverse pawl to keep the reverse-reverse pawl and the split plate in a substantially parallel relationship. The hardened part of the throat plate can keep the throat plate from being damaged by the serrated edge of the anti-reversal pawl, and prevent sticking when the saw blade falls.
What are the main structural characteristics of the table saw?
The main structural feature of the table saw is the use of two saw blades, the main saw blade and the scoring saw blade. When cutting, the scoring saw is used for cutting in advance, and the bottom surface of the processed plate is first sawed to scribe the depth of the bottom surface. The depth is 1-2mm and the width is 0.1-0.2mm thicker than the main saw blade. Groove to ensure that the edge of the saw edge will not tear when the main saw blade is cutting, so as to obtain a good sawing quality.
Table saw is also an indispensable tool for furniture production. According to the size of the table, it can be divided into two types: Portable Table Saw and Cabinet Table Saw. Because home woodworkers pursue small size and light weight, they generally choose portable table saws. The following are also explained with the goal of portable table saws.
Table saw purchase points guide size
Few people pay attention to the size of the guide rail. I am the first one to talk about the guide rail size, because some portable table saw manufacturers use small-size T-rails. When purchasing, you must try to "'Avoid buying a table saw with such a small size T-rail"', because it is difficult to find accessories of this size in the market, such as feather boards, tenon openers, push handles, etc. Can't buy. That is to say, once you buy a table saw with this small size T-rail, you cannot buy any accessories.
Standard size rail: 3/4 inch wide, 3/8 inch deep, such as DeWalt DW745
Small size T-rail: 5/8 inches wide and 1/4 inches high, such as Makita MLT100
Saw blade size
If the size of the saw blade required by the table saw is different from what is commonly used, it may be difficult to match the saw blade. The specifications of the saw blade used by the table saw are generally:
Diameter: 10 inches
Arbor: 5/8 inch
Saw road width Kerf: 0.058 inches (1.5mm) ~ .118 inches (3mm)
DADO
The portable table saw does not need DADO at all for the following reasons:
The table saw is small in size, and it is difficult to slot large wood with the table saw
It is troublesome to replace the DADO saw blade, and it is more troublesome to adjust the thickness of DADO, but it is not meaningful for mass production.
Small size wood can be slotted multiple times with ordinary saw blades, and large size wood can be slotted with electric milling
Backing system
The most basic and important requirement of the backing system is to keep parallel with the saw blade. If the parallelism cannot be guaranteed, the loss of accuracy is still a small matter, and what is worse may be that the feed cannot be pushed, burned or even the wood bounces. Among the portable table saws, ``The best backer is the DEWALT table saw'', because it uses a special gear system. The front and back of the ruler must move in parallel under the drive of the gear.
