We manufacture grinding wheels for saw sharpening in several specifications, depending on the material to be sharpened and the operating conditions. Saws can be sharpened offhand on simple machines, or automatically on more perfect machines. For offhand sharpening it is better to use harder wheels, because the hand pressure is not equal and the consequence is an excessive consumption of the wheel. For automatic sharpening the use of softer wheels is advisable, because the pressure is equal and an overheating and burning of the teeth is prevented.
For offhand sharpening we advise the use of grinding wheels in aluminum oxide regular (A or 3 A), grade M-O, or in mixed aluminium oxide 52A. For automatic sharpening grinding wheels in special aluminium oxide (2 A, 4 A) are recommended.
