Tri-ac Cutting Tools
a stick blade-type face hobbing system used for completing operations. In the face hobbing process, the cutting action causes the blades to cut on both the pressure angle side and the top portion of the clearance side. Because of the negative rake on the clearance side of a conventional blade, excessive tool wear is produced.
the tri-ac® system solves this problem with a patented rake angle modification on the front face of the blade. This modification produces a positive hook of front rake on the top portion of the clearance side, thus eliminating the need for a bottom cutting blade.
the continuous indexing method requires a second rotational coupling (electronic gear box) between the cutter head rotation and the workpiece rotation. For this reason the method is also called a three-axes process. This is where the name tri-ac is derived.
Wedge-ac (cutting Tools)
Hardac (Cutting Tools)
Adjustable in both an angular and radial plane, these inserted blade cutters are used for completing or finishing. Truing with a proximity-equipped unit allows positioning of blade profiles to within 0.000040 inch. The rigid design even enables completing of spiral and hypoid pinions and gears directly from the solid blank.
Fine Pitch Hobs (Cutting Tools)
Unground as fine as 48 DP. Ground hobs to 80 DP. Accuracy up to class AAA.
These small hobs are custom-engineered and manufactured by tool craftsmen on equipment developed especially for that purpose. Special inspection techniques assure that tolerances are consistently maintained within AGMA, DIN or JIS accuracy requirements.
