TO
SHARPEN DULL INSERT, INSTALL INSERT INTO SHARPENING FIXTURE AND CLAMP
SECURELY. TAP INSERT DOWN TO BE SURE IT IS FULLY SEATED AGAINST BOTTOM
FACE. MOUNT FIXTURE ON MAGNETIC
CHUCK OF SURFACE GRINDER HORIZONTALLY OR VERTICALLY DEPENDING ON THE WHEEL
BEING USED.
**IMPORTANT: IF GRINDING HORIZONTALLY, POSITION FIXTURE SO THAT
GRINDING WHEEL PRESSURE AGAINST INSERT IS TOWARDS SCREW HEAD STOP IN FIXTURE
THAT CONTACTS BACK END OF INSERT, NOT
TOWARDS END OF INSERT WITH FORM.
REMOVE
STOCK EVENLY FROM ENTIRE TOP SURFACE OF INSERT SO THAT TOP AND BOTTOM SURFACES
ARE PARALLEL WITHIN .001” AND AS SMOOTH AS POSSIBLE.
IT IS ESSENTIAL THAT THE TOP SURFACE OF THE INSERT IS FLAT AND FREE OF
STEPS SINCE STEPS WOULD CAUSE INSERT TO NOT REPEAT CENTER SETTING WHEN REMOUNTED
IN HOLDER AND COULD ALSO RESULT IN LACK OF RIGIDITY AND POSSIBLE BREAKAGE OF
INSERT AND DAMAGE TO HOLDER.
GRIND
OFF ONLY MINIMUM AMOUNT NECESSARY TO REMOVE WEAR OF CUTTING EDGES.
REMEMBER, INSERTS SHOULD BE RESHARPENED PRIOR TO .005” WEAR.
ALWAYS
SPARK OUT FINAL GRINDING PASSES FOR BETTER FINISH AND LONGER TOOL LIFE, HONING
OF TOP SURFACE WILL FURTHER INCREASE TOOL LIFE AND IMPROVE FINISH.

WHEEL
GRADE RECOMMENDATION FOR CARBIDE INSERTS: CMD180
R100 B-1/8
STYLE
OF WHEEL: IF GRINDING HORIZONTALLY
USE D1A1
IF GRINDING VERTICALLY
USE D11V9
TAKE
.0001/.0003” DEEP PASSES IF GRINDING DRY.
TAKE
.0002/.0005” DEEP PASSES IF GRINDING WET.
FOR
BEST RESULTS TRUE UP WHEEL AS PER GRINDING WHEEL MANUFACTURER’S INSTRUCTIONS
AS NEEDED.
********************
WARNING ********************
IT IS ALWAYS IMPORTANT
TO BE CERTAIN THAT INSERT IS CLAMPED SECURELY IN THE TOOL HOLDER.
IF INSERT IS NOT CLAMPED SECURELY MACHINE DAMAGE OR PERSONAL INJURY CAN
RESULT.
EXTRA CARE MUST BE
TAKEN WHEN YOU HAVE RESHARPENED THE INSERT (INCLUDING THE 1/8” SPACER WHEN
USED) DOWN TO ABOUT ¼” TOTAL THICKNESS SINCE IT WILL NO LONGER BE POSSIBLE TO
CLAMP THE INSERT IN THE HOLDER. THIS
IS DONE INTENTIONALLY SO THAT INSERT WILL NOT BE USED WHEN IT’S THICKNESS IS
LESS THAN THAT WHICH IS REQUIRED TO SUPPORT THE CUTTING EDGE.
THEREFORE, IT IS
IMPORTANT TO BE CERTAIN THAT CLAMP IS ACTUALLY CLAMPING ON INSERT, HOLDING IT
SECURELY IN THE HOLDER AND NOT MERELY BOTTOMING OUT.
