Sliding table saw
The sliding table saw has, unlike the simple table saw a sliding table for guiding the workpiece instead of longitudinal and transverse stop.
The sliding table saw is now standard equipment in a joinery . It is used for the precise cutting and angular distribution of panel -shaped workpieces, wood-based materials and trimmed and untrimmed solid wood. It is also increasingly used for cutting non-ferrous metals and plastic .
Machine principle
The rip fence of a normal table saw is not suitable for creating a straight edge on a board with a tree edge . When making the first longitudinal cuts on the trimmed solid wood, the cut material must be pushed over the saw table with your hands, whereby a straight cutting line can hardly be achieved.
Even with other cutting tasks, the precision of a sliding table saw cannot be achieved by manually pushing the material to be cut on the saw table and along stops. With this, the material lies on a sliding table, which itself slides past the saw blade with the help of smooth linear guides . When trimming, there is no need for dressing as an additional work step, and only a single cut is required. Since precise and parallel longitudinal cuts and right-angle cross- cuts can be made on the sliding table saw without reworking, the carpenter can achieve a glued cut in just one work step.
Structure / functionality
The saw unit is the core of every saw. It is height adjustable and, depending on the machine equipment, can be swiveled from −46 ° to + 46 °. An important feature is smooth running in all speed ranges, without which precise cutting would not be possible.
The sliding table saw has stops on both the left and right of the saw blade. With the rip fence to the right of the saw blade, panels can be divided, for example. The angle stop to the left of the saw blade enables 90 ° angles to be cut. The miter fence can also be located to the left of the saw blade, which can be used to cut mitres and face angles. Crosscut fence and miter fence can also be combined as a crosscut-miter fence. To set the cutting dimensions, stops are provided, the setting of which can be checked on analog or digital displays. The cutting height and the swivel angle of the saw blade are usually adjusted with a foot lever, a hand wheel or the machine control. The sliding carriage is moved by hand or by an electric motor.
A stationary workpiece is guided through the rotating saw blade with the sliding table . In this way, a straight trimming cut can be achieved, which in turn is the prerequisite for precise parallel and angular cuts. The large double rollers of the sliding table hold the upper carriage in connection with the undercarriage in the guide rods. A special feature, which is available in some variants, is a laser alignment light, which serves as an aid to positioning the workpiece for the trimming cut by projecting the course of the cut onto the workpiece with a laser beam.
application areas
Panel saws are no longer just woodworking machines , they also saw plastic or non-ferrous metals . In addition, they are not only used for cutting, but can also mill grooves . Panel saws can be found at classic woodworking companies such as carpenters, but also in industry, e.g. B. at large furniture manufacturers, window manufacturers, etc.
