    • A table saw is disclosed comprising a main saw unit and an air table attachment. The air table is mounted adjacent a main support surface of the main saw unit, and includes a body portion and a generally planar table top. The body portion has a plurality of subsections formed therein. The table top is substantially coplanar with the main support surface, and is attached to the body portion to cover the subsections so that a plurality of holes through the table top communicate between the subsections and the exterior. A shop vacuum produces either a partial vacuum or a stream of pressurized air, and a manifold attached to the body portion selectively communicates the vacuum or stream of air to one or more of the subsections to respectively produce either a suction force or a supporting air cushion over a variable portion of the table top. Preferably, the air table is movable along the front and rear guide rails in a direction transverse to the direction of rotation of the saw blade. The air table can also be moved from one side of the rotatable blade to the other side to accommodate the workpiece.
    • 公开了一种台锯,包括主锯单元和空气台附件。 空气台安装在主锯单元的主支撑表面附近,并且包括主体部分和大致平面的桌面。 主体部分具有形成在其中的多个子部分。 桌面与主支撑表面基本上共面,并且附接到主体部分以覆盖子部分,使得穿过台面的多个孔在子部分和外部之间连通。 商店真空产生部分真空或加压空气流,并且附接到主体部分的歧管选择性地将真空或空气流连通到一个或多个子部分以分别产生吸力或支撑气垫 在桌面的可变部分上。 优选地,所述空气台沿着与所述锯片的旋转方向横切的方向沿着所述前导轨和所述后导轨移动。 空气台也可以从可旋转叶片的一侧移动到另一侧以容纳工件。
