    摘要： A band saw with a complex coordination of a tilting motion and a translational motion between the workpiece and the band saw blade, so that a curved cut is made in the workpiece. The geometric parameters of the cut can be continuously adjusted. This makes it possible to optimize a contact length of the saw blade in the workpiece, which is an important factor in the cutting process. It is thus possible to saw workpieces made of stone and similar materials that are typically difficult to cut. The cut and the contact length of the saw blade can be tailored individually to each workpiece to be sawed. Thus, workpieces of different geometrical dimensions and different material properties, in particular with different material hardnesses, can be processed using the band saw according to the invention without having to undertake significant changes.

    摘要： In a method and a system for determining the feeding sped when bandsaw cutting a workpiece, the tough pitch TP of the bandsaw blade is determined in a first unit (6) depending on the shape and dimensions of the workpiece. In a second unit (12) feeding depth per tooth is determined depending on properties of the workpiece material and the width of the bandsaw blade. The bandsaw blade velocity BS is determined in a third unit (22) from the width W of the workpiece and the hardness of the workpiece material, whereafter the cutting time T is determined in a first calculating unit (30) from the height H of the workpiece, the feeding depth per tooth, the tooth pitch TP and the blade velocity BS. In a second calculating unit (32) the feeding speed MH for the bandsaw blade is then determined by the equation MHnullH/T. A computer program, when executed on a computer, performs this determination of the feeding speed when cutting a workpiece with a bandsaw from supplied input data.

    摘要： A horizontal bandsaw is mounted in a tool carrier above a workpiece location. Before it starts cutting the bandsaw is tilted an angle between 3.degree. and 10.degree. and after the initial cut that angle is maintained during the rest of the cut until the intended depth of cut is reached or closely approached, when the saw tilt is removed as the structure containing the bandsaw is swung to orient the bandsaw horizontally. If the depth of cut is a complete cut through, the advantage of a minimum erosion of the center selvage of the workpiece support is assured. Mechanical limits are provided for the vertical displacement by tilt at one side of the workpiece and on that side one of the guides of the structure supporting the bandsaw has a hydraulic changeover control in which the angle of tilt is set by adjustable screw-stops which cooperate with stop plates mounted on the structure supporting the bandsaw.

    摘要： A method and apparatus for controlling the cutting feed of band saw machines for obtaining an optimum feed rate with the same safety against straying of the saw cut, according to which the saw band is maintained continuously within the area of its teeth under a residual tensile stress (.sigma..sub.Z.sbsb.Res) adjusted at least approximately to a constant value. For this purpose, a desired value is selected for the residual tensile stress, determined experimentally under practical conditions, which is correspondingly converted in case of load conditions of the saw blade deviating from the experiment, and this desired value is compared with the actual value. The actual value (.sigma..sub.Z.sbsb.Res) is derived as a difference from the tensile stress (Z) in the critical saw band point and the bending stress .sigma..sub.B caused by the feed, to be .sigma..sub.Z.sbsb.Res =.sigma.Z-.sigma.B>0. The actual value is adjusted to the desired value by varying the feed rate; the sum total of all feed forces or the sagging angle of the saw band is selected as a measure for the actual value. As a result thereof the danger of straying is precluded and yet an economically optimal feed rate is attained in band saws.

    摘要： A bandsaw machine is provided with a device in which a check valve having a tappet or projection and a flow control valve are provided in parallel with each other in a hydraulic passage connecting a hydraulic pump with a hydraulic cylinder for raising a cutting head holding a bandsaw blade, a micro switch is electrically connected with an electric motor for driving said pump and a solenoid operated valve for controlling hydraulic fluid through a time limit switch, a vertical elongate rod is vertically movably mounted on a part of said cutting head and is provided at its bottom end with an horizontally elongate plate which is touchable with a material to be cut, a horizontal elongate plate is fixed to the top end of said vertical elongate plate so as to depress said tappet or projection of said check valve and actuate said micro switch. The vertical elongate rod is so designed as to be brought into and out of contact with the material to be cut in order to automatically determine the upper limit of the vertical movement of the bandsaw blade and automatically control the lowering speed of the bandsaw blade during its idle time.
