A method of grinding a plurality of surfaces on a cutting blade, said method comprising:
- positioning a cutting blade on a grinding machine, said grinding machine including a grinding wheel wherein said grinding wheel is cylindrically shaped and comprises a peripheral abrasive grinding portion having a first side, a second side and an outermost surface, a first grinding edge being defined by the intersection of said first side and a outermost surface, said second grinding edge being defined by the intersection of said second side and said outermost surface,
- rough grinding one or more of said surfaces,
- finish grinding one or more of said surfaces, wherein said rough grinding is carried out with said first grinding edge and said finish grinding is carried out with said second grinding edge.
A method of grinding cutting blades comprising:
- providing a cylindrical-shaped grinding wheel having an axis of rotation and including abrasive material located radially outward from said axis, said abrasive material defining a peripheral portion of said grinding wheel, the abrasive peripheral portion comprising opposed first and second sides and an outermost surface, wherein said first side and said outermost surface intersect to define a first grinding edge and said second side and said outermost surface intersect to define a second grinding edge,
- positioning said grinding wheel on a cutting blade grinding machine,
- positioning a cutting blade on said grinding machine, said cutting blade having one or more surfaces to be ground,
- rough grinding at least one of said one or more surfaces with one of said first grinding edge and said second grinding edge,
