G-716 Semi-Automatic Cutterhead Grinder


The G-716 Semi-automatic Cutterhead Grinder is used to sharpen 7” to 16” 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.

Completely Enclosed Grinding Area

Completely enclosed grinding area provides for a safer and cleaner grinding room. The work area is completely enclosed by a gas spring operated hood. The closed hood provides a tight seal with the coolant recovery tray. Coolant and grinding debris are carried away by the flooded coolant system and returned to the coolant reservoir. Since all the grinding debris and coolant are completely contained within the grinding hood there is no need for a pneumatic airborne particulate collection system.
