An adjustable fence can be easily and securely attached to the support surface of a boring, drilling or cutting device. The fence includes a base that is releasably attachable to the support surface of the boring, drilling or cutting device adjacent boring, drilling or cutting mechanism. The base includes a pair of brackets located at each end of the base that rotatably support a barrier therebetween. The barrier or fence angle includes a clamping mechanism engageable with each of the brackets on the base in order to releasably secure the fence in the desired position relative to the base. The base also includes a number of stops moveably secured to the fence that can be positioned on the fence angle at the desired location to function as a stop for the movement of the work piece relative to the fence while acted on by the boring, drilling or cutting mechanism.

A method for sawing metal workpieces is disclosed. The method includes: controlling the clamping jaws (8) via the machine controller (12) to clamp a workpiece placed on the sawing bench (2); inputting an offset value into the machine controller (12); advancing or retracting the clamping jaws (8) in order to move the workpiece into a zero position using the offset value, opening the clamping jaws (8), moving the clamping jaws (8) to an initial position, re-clamping the workpiece located in the zero position, the clamping jaws (8) being in their initial position, and moving the clamped workpiece from the zero position into a cutting position by way of a feeding movement, the cutting position being a position in which that point of the workpiece is located in the cutting plane (7).

A device and method are disclosed. An embodiment of a sliding sled for use on a saw table includes a flat plate, adjustable guide fences on the flat plate at a fixed pivot end to create an oblique angle relative to the saw table, an indexing system including angle indicators to set the angles of the adjustable guide fences, roller bearings on the bottom side of the flat plate for riding on the ACCU-SLICE rail, and a sawdust shield to keep sawdust off the roller bearings and ACCU-SLICE rail. Guide fences may have a fixed pivot end and a movable end and a locking bolt to temporarily fix the movable end at a desired position on the plate. The movable end of the adjustable guide fences may align with the angle indicators when the angle of the adjustable guide fence relative to the cutting plane corresponds to the angle indicators.

A sawing machine for bevel cuts having an upper saw portion with two running wheels, one of which is motor driven, a saw band which rotates about the running wheels, a lifting and lowering device for the upward and downward movement of the upper saw portion to move the saw band with a sawing advance movement in a sawing region, a transport path for supplying a workpiece in a supply direction to the sawing region, a frame, on which the upper saw portion is retained and which is pivotable about a vertical axis in order to adjust a bevel angle between the saw band and the supply direction. A movable sawing table is arranged in the sawing region for positioning the workpiece to be sawn and a clamping vice for clamping the workpiece during the sawing operation. The sawing table and the clamping vice are constructed to be movable in and counter to the supply direction.

A feed/clamp apparatus includes a feed vise mechanism provided upstream from a cutting position, and a downstream vise mechanism provided just downstream from the cutting position. The feed vise mechanism includes first/second feed vise jaws, a downstream moving cylinder for moving the first feed vise jaw, and a downstream shifting cylinder for shifting the second feed vise jaw. The downstream vise mechanism includes first/second downstream vise jaws, a downstream moving cylinder for moving the first downstream vise jaw, and a downstream shifting cylinder for shifting a second downstream vise jaw. A vise surface of the second downstream vise jaw is located on one side of the vise reference position when the downstream shifting cylinder is located its stroke end on the one side. A thrust force of the downstream shifting cylinder toward the one side is made equal to a thrust force of the downstream moving cylinder toward another side.
