All cuts that need to be made in a straight line can be made with the 7 inch tile saw blade reviews. It saws materials such as boards, wood-based materials, solid wood and many more millimeters accurately, cleanly and precisely.
The concept of the sliding table saw dates back to 1906 and was developed by Wilhelm Altendorf. The new thing about the saw was that, unlike the ones used until then, it could also precisely machine workpieces that did not have a straight reference edge. For this purpose, the sliding table of the sliding table saw has a ball bearing mounted sliding table which is located to the left of the saw blade from the operator’s point of view. This additional sliding table can be moved back and forth during work without much effort, as required. On the right side the workpieces protrude and can be cut off precisely with the help of a trimming cut. The trimming table usually has a size of 3 meters, so that common half format panels measuring 2.75 x 2.10 meters can be processed. However, even if smaller tables are required, they are offered by most circular saw manufacturers.
The main table of the sliding table saw is located on the right side of the saw blade. Here the workpieces can be adjusted to the required width and separated with the help of a rip fence.
If required, an additional cross table can be mounted on the left side. The height of the table is determined by a telescopic or articulated arm fixed to the lower side of the housing. The table serves to prevent large panels from tipping over during processing. It is also possible to attach another stop for angle cuts to the table. In turn, the stops can be adjusted to the desired cutting length and distance to the cutting line.
What Does The Sliding Table Saw Do?
A considerable advantage of the sliding table saw compared to conventional table saws is the possibility of cutting even very large workpieces, such as panels, to size.
Furthermore, sliding table saws offer the possibility to determine the height of the sawing unit and thus the cutting height. If a cutting height is chosen which is smaller than the thickness of the workpiece, a groove can be cut in the width of the saw blade. To obtain a wider groove, the cut can be made a second time, then slightly offset. It is also possible to cut a rebate in this way. By adjusting the cutting height, the quality of the cut edges can also be influenced. For example, if there is a high overhang, the saw blade is inserted almost vertically into the wood, which results in a clean-cut above and tears below the workpiece to be processed. At a lower overhang, the cleanliness of the cut edges alternates between above and below. In other words, the smaller the overhang, the cleaner the cut below and the more torn out the cut above.
In order to obtain a clean cut edge even on sensitive workpieces, a so-called scoring device can be installed in front of the saw blade on many sliding table saws. This scores an approximately 3-millimeter deep groove in the cutting run. The width of the groove should be slightly wider than the saw cut and precisely centered to the saw blade.
The functions listed above are more standard and are designed for right-angled workpieces. But with a form circular saw, angles can also be cut. The angle stop, which is released from the 90 degree position and set to a different degree setting, offers help here. Another nice feature of many saws is the possibility to tilt the saw blade by up to 46 degrees to the right. On some sliding table saws this is also possible to tilt to the left. This feature makes it easy to change the sides of the workpieces.
The sliding table saw also allows cuts with an inclined saw blade and turned angular stop. This type of sawing is called Schifterschnitt and is considered a challenge. As soon as the saw blade is tilted or the crosscut fence is no longer in the 90-degree position, the length values shown on the flaps are no longer correct. The use of an automatic length compensation provides help here.
Setting The Sliding Table Saw
A not inconsiderable difference between the sliding table saws lies in how they are set. The following settings are the most important ones:
- Workpiece width on the rip fence;
- Workpiece length at the stop flaps;
- Cutting height at the sawing unit;
- Cutting inclination at the sawing unit;
- Cutting angle at the crosscut fence.
The easiest way to adjust the settings is to move, turn or crank the stops until a desired value on a scale is reached. The increase of this is the so-called fine adjustment, which can often be done with a magnifying glass. Detent points for frequently used angles can make the adjustment much easier. Even more comfort is offered by electronic and digital adjustment options.
A further aid for adjusting the saw is cranks which are located at the working position and show values on a display. This means that the user does not have to leave his working position to change the settings. The next step is the electric cranks which can be operated by means of a push-button.
The high-end and most modern variant is the so-called CNC axis. Here, all desired settings can be entered on a touch screen and are transferred fully automatically. A manual adjustment of the saw is therefore completely unnecessary. Settings pre-programmed in the office can also be fed into the saw in this way.
Cutting programs and assistants
Modern systems support the operator in coping with the tasks of grooving, rebating, slotting, tenoning and the cutting of difficult cuts and blanks. Calculations are taken over by the system and the user is guided step by step through the working steps. Development has already reached the stage where individual sliding table saws communicate with apps specially developed for them and can be shown about these work steps.
