Thorvie Saw Blade Sharpening Machines Out Perform Competition
Saw blade sharpening machines by Thorvie International have the winning combinations you will not find anywhere else. With the combination of superior design and Thorvie’s dedication to helping you succeed, there is really no contest. Offering over 20 tool fixtures for the AV-40 and AV-42 sharpening systems, Thorvie grinders provide a more complete sharpening service. Many competitors offer a maximum of four tool sharpening fixtures, not allowing you to offer a complete service.
The AV-40 saddle assembly is solid with four sealed bearings and no play whatsoever. Other saw sharpening systems have three bearings in their saddle assembly. The AV-40 will face, top and side grind saw blades while most other grinders will only face grind. To properly sharpen and balance saw blades, you must face and top grind the tooth to restore the cutting edge. Compare Thorvie to the competition.
The topic of sharpening forstner bits has come to my attention more frequently the past couple months. To sharpen forstner bits, I use the router bit fixture on the AV-40 saw and tool sharpening machine. The proper grinding wheel to use is either a 4″ to 6″ CBN face grinding wheel or a resin bond wheel. You sharpen these bits similar to face grinding a saw blade. Sharpen the face of these cutter instead of the smaller top section. The top section is harder to align to the grinding wheel with the center point tip getting in the way. Align the face of the cutter to the grinding wheel and sharpen it until a slight burr appears.
If the forstner bit has a 2 cutter system, use the same number of grinding passes on each cutter so you sharpen each cutter to the same height. On the outer rim of the forstner bits, there are usually small cutter teeth. To sharpen these I use either use a dremel with the thin flat resin bond wheel or a belt sander to just touch up the face on the outer teeth.
