Newman Whitney G716 Semi Automatic Knife Grinder

The G-716 Semi-automatic Cutterhead Grinder is used to sharpen 178mm to 406mm diameter eased edge, milled to pattern, and fingerjoint cutterheads. Worktable traversing is automatic and has adjustable stops. Cutterhead indexing is manual. Each knife is held against a positive stop while being ground !!!

No Index Plate To Change
No index plate to change when working with heads with different numbers of knives. The use of an index plate assumes that the knives and head separations are uniform throughout, which is often not the case. If the height of the knife is high or low, then the front face of the knife will vary from knife to knife making the task of grinding difficult. The one constant is the back face of the knife, therefore the use of an indexing stop against the back face will provide for accurate indexing regardless of the irregularities in the knives and head slots.
