Abstract
A machining tool beveling the edges of workpieces such as sheet metal is movable relative to the workpiece in the feed direction along the edge of the workpiece and in an action direction perpendicular to the feed direction. It has at least two adjacent cutting edges extending in the feed direction, one of which is the leading edge and the other of which is the trailing edge which is offset from the leading edge. The trailing cutting edge will effect a further cut in the workpiece as the tool is moved along the edge of the workpiece and reciprocated against its edge portion.
Claims15
A machining tool for beveling edges on workpieces moveable in a feed direction along the edge of the workpiece to be machined and in an action direction perpendicular to the feed direction relative to the workpiece, said tool having a drive axis in the action direction with a mounting portion at one end for engagement in a tool holder of the beveling machine to effect reciprocation thereof in the action direction and a cutting portion at the other end, said cutting portion of said tool having at least two adjacent cutting edges extending transversely of said drive axis in the feed direction and providing at least one leading cutting edge and at least one trailing cutting edge, said at least one trailing cutting edge in the feed direction being offset below the leading edge in the action direction from said leading cutting edge to effect a further cut in the workpiece after it has been cut by said leading edge.
A machining tool for beveling edges on workpieces moveable in a feed direction along the edge of the workpiece to be machined and in an action direction perpendicular to the feed direction relative to the workpiece, said tool having a drive axis in the action direction with a mounting portion at one end for engagement in a tool holder of the beveling machine to effect reciprocation thereof in the action direction and a cutting portion at the other end, said cutting portion of said tool having two adjacent cutting edges extending transversely of said drive axis in the feed direction and providing a leading cutting edge and a trailing cutting edge, said trailing cutting edge in the feed direction being offset below said leading edge in the action direction from said leading cutting edge to effect an additional cut in the workpiece after it has been cut by said leading edge, at least one of said cutting edges extending substantially perpendicularly to the action direction.
A machining tool for beveling edges on workpieces moveable in a feed direction along the edge of the workpiece to be machined and in an action direction perpendicular to the feed direction relative to the workpiece, said tool having a drive axis in the action direction with a mounting portion at one end for engagement in a tool holder of the beveling machine to effect reciprocation thereof in the action direction and a cutting portion at the other end, said cutting portion of said tool having three adjacent cutting edges extending transversely of said drive axis in the feed direction and providing two end cutting edges and a middle cutting edge, either of said end cutting edges constituting a leading cutting edge and said middle cutting edge comprising a trailing cutting edge in the feed direction offset in the action direction below said end cutting edges to effect a further cut in the workpiece after it has been cut by said leading cutting edge, and at least one of said cutting edges extending substantially perpendicularly to the action direction.
