A double-saw band saw machine includes a base, a first band saw unit, a second band saw unit, a feeding unit and a clamp unit. When an object to be sawn is located in a sawing area between the first and second band saw units, the first and second motors control the first and second frames to move toward each other along the first axial direction, so that the first and second band saw blades can be used to cut the object to be sawn simultaneously. Hence, the sawing efficiency of the double-saw band saw machine is improved, and the replacement interval for the first and second band saw blades is extended.

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.
