Abstract
An edge milling cutter assembly for cutting opposite edges of a workpiece, has a first cutting assembly; a second cutting assembly positioned a predetermined distance from the first cutting assembly; a first guide roll assembly positioned in front of the first cutting assembly; a second guide wall assembly positioned in front of the second cutting assembly; wherein the first guide roll assembly and the second guide roll assembly are movable in relation to each other in equal distances; and a mechanism which engages the first guide roll assembly and the second guide roll assembly to facilitate equal movement of each of the guide rolls in such a manner that the first and second cutting assemblies cut equal amounts of material from opposite edges of the workpiece.
Claims15
An edge milling cutting assembly for cutting opposite edges of a workpiece, comprising:
- a first cutting assembly comprising a first cutting head;
- a second cutting assembly comprising a second cutting head positioned a predetermined distance from said first cutting assembly, said first cutting assembly is positioned at a first angle with respect to a vertical axis of said assembly and said second cutting assembly is positioned at a second angle with respect to said vertical axis of said assembly;
- wherein said first cutting head and said second cutting head each removes the same amount of material from opposite edges of said workpiece as said workpiece is fed through said edge milling cutting assembly between said first cutting head and said second cutting head;
- and
- wherein each of said first and said second cutting heads comprises cutting inserts forming separate cutting edges spaced along an outer perimeter of said first and second cutting heads;
- a first guide roll assembly positioned in front of said first cutting assembly;
- a second guide roll assembly positioned in front of said second cutting assembly;
- wherein said first guide roll assembly and said second guide roll assembly are movable in relation to each other;
- and
- a mechanism which engages said first guide roll assembly and said second guide roll assembly.
A method for milling opposite edges of a workpiece, comprising:
- providing a pair of opposed guide rolls for guiding and aligning said workpiece for cutting;
- feeding said workpiece past said guide rolls such that opposite edges of said workpiece engage said guide rolls;
- providing a means for moving said guide rolls an equal distance to accommodate said workpiece;
- providing a pair of opposed left hand and right hand cutting heads for cutting opposite sides of said workpiece, said left hand and right hand cutting heads are oriented at an angle with respect to each other;
- wherein each of said left hand and said right hand cutting heads comprises cutting inserts forming separate cutting edges spaced along an outer perimeter of said first and second cutting heads;
- aligning said workpiece centrally between the opposed cutting heads via said guide rolls;
- feeding said workpiece past said opposed cutting heads;
- and,
- cutting equal amounts of material from opposite sides of said workpiece with said opposed cutting heads.
