A portable bandsaw attachment for cutting symmetrical or asymmetrical convex curved sides into a multisided three dimensional workpiece comprising a rotating table that supports the workpiece, a stationary base that supports the rotating table and provides an attachment point for the rotating table, laterally movable guides and backstop arrangement attached to the rotating table for locating and securing the workpiece relative to the bandsaw blade. The attachment can include handles to grip and turn the rotating table, an opening in the stationary base to provide clearance for the bandsaw blade, and means for securely mounting the stationary base to the bandsaw table.

A bandsaw makes simultaneous, spaced-apart cuts in hard or soft materials with a single bandsaw blade. The invention is ideally suited to cutting spaced-apart parallel surfaces to form support blocks, however, different embodiment may be controlled or programmed to make parallel or non-parallel cuts at varying angles. The single bandsaw blade rides on circular wheels on both sides of a gap or passageway, such that a first portion of the blade crosses the passage along a first, upper path, and a second portion of the bandsaw blade crosses the passage along a second, lower path. A table moves the material through the passage, whereupon the material is simultaneously cut along two planes corresponding to the upper and lower paths of the bandsaw blade. A preferred embodiment includes a first set of upper and lower wheels on one side of the passage, and a second set of upper and lower wheels on an opposing side of the passage.

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 band saw includes a first blade guide assembly and a second blade guide assembly which guide the band saw blade through a cutting zone. The first blade guide assembly and the second blade guide assembly are each supported for pivotal movement about a pivot axis between a first angular position and a second angular position. At the first angular position, the first and the second blade guide assemblies hold the band saw blade at a first angle with respect to the wheel contact plane. At the second angular position, the first and the second blade guide assemblies hold the band saw blade at a second angle with respect to the wheel contact plane, the second angle being different than the first angle.

A system for removing one or more three-dimensional workpieces manufactured in additive manufacturing environment from a substrate plate is disclosed. The system includes an adjustable support tooling apparatus, a grinder, a cut-machining device, a work tank, a wire discharge machine and coolant pump filtration system. The adjustable support tooling apparatus is supporting a three-dimensional workpiece while it is being detached from a substrate plate by cutting device. The adjustable support apparatus of the present disclosure is also easily adaptable to various weights and geometric of workpiece. The improved substrate plate preparation machine in additive manufacturing enables to complete a job at one place, wherein the job is cutting the work piece and grinding the uneven cut surface of the substrate plate, thereby the ground substrate plate can be reused.
