Abstract
A grinding jig for holding a blade tool having an edge in a grinding machine. The grinding jig may have a first and a second clamp half arranged to hold between them at least a portion of a blade tool. An elongate support portion may support the grinding jig onto a support bar of a grinding machine. The elongate support portion may comprise a front end abutment surface and a rear end abutment surface. The front and rear end abutment surfaces may be spaced to receive a portion of a support bar such that the grinding jig may be moved back and forth relative to the support bar in a direction parallel with its longitudinal center axis.

A grinding jig for holding a blade tool having an edge in a grinding machine, said grinding machine, the grinding jig comprising:
- first and second clamp halves arranged to hold between them at least a portion of a blade tool;
- an elongate support portion for supporting the grinding jig onto a support bar of a grinding machine,
- wherein the elongate support portion comprises a front end abutment surface and a rear end abutment surface for abutment against a support bar of the grinding machine, and
- wherein the front and rear end abutment surfaces protrude radially outward from the support portion and are spaced apart such that a portion of the support bar of the grinding machine may be received between the front and rear end abutment surfaces such that the grinding jig may slide back and forth between the front and rear abutment surfaces, relative the support bar, in a direction parallel with the longitudinal center axis of the grinding jig;
- first and second separate grinding jig halves, which are mutually facing each other and respectively comprise the first and second clamp halves and respectively comprise first and second halves of the elongate support portion;
- and
- wherein the grinding jig is arranged such that the first and second separate grinding jig halves may be releasably forced towards each other to hold the blade tool between the first and second clamp halves via an actuator and wherein the first and second separate grinding jig halves each comprises a respective front abutment half and a respective rear abutment half that include respectively the front and rear abutment surfaces,
- wherein the front abutment halves and the rear abutment halves are arranged spaced apart from each other on the respective first and second portions of the first and second halves of the elongate support portion and configured for abutment with the support bar of the grinding machine.
