Machine for machining circular saw blades

摘要

The invention relates to apparatus for machining circular saw blades and more particularly to the transport means for conveying workpieces to the machining stations of the apparatus. In accordance with the invention, the storage capability of the apparatus is accomplished by subdividing the conveying means into a work path leading through the machining stations; a return path leading through a feeding and discharging station; two branch paths wherein an endless conveyor is arranged only along the work path and associated with the branch paths there are shifting means capable of shifting a work piece carriage from the branch path to the return path; and that on the return path, work piece carriages are maintained at smaller distances than those of the endless conveyor whereby the storage capacity of the apparatus is increased. The apparatus is also adjustable to feed a plurality of different saw diameters for machining. In each machining station there is a feed device for turning a circular saw blade affixed to an arbor of the workpiece carriage so that the saw teeth are advanced one tooth spacing or in special cases several tooth spacings, each time the feed is initiated.
