of the tooth was correctly chosen with reference to material to be worked.
The principle is as follows:
Material Back angle Spacing
Steel 8° 22°
Stainless Steel 6° 15°
Non-metal 12° 25°
The gullet shape should be big enough compared to spacing.
Quick removal of the material cut off, correct depth and the gullet fillet are of relevance. The gullet should
be sufficient to provide for removing bent splinter resulting from the tooth cutting operation. When the tooth
leaves the cut, the splinter will fall off the gullet.
An alternating edge saw is often used for small spacing, primarily up to 4 mm.
Bigger and higher teeth and wider and lower ones are intended for larger and firmer pieces, typically of
spacing above 4 mm. These teeth assure for the splinters not to be of a uniform length. Should the splinter
be cut in a normal way, it would have warmed up, expanded and would have been wider than the cutting
width. Consequently, the splinter would stick in and it could not be removed from the cut. Therefore, a wider
and a lower tooth should be positioned 0.2 - 0.4 mm higher that the bigger and higher one. The bigger is
the spacing, the higher the larger tooth should be positioned compared to a wider and lower one.
Hence only special tools are appropriate for grinding the teeth. If the cutting power of the disk is wearing off,
do not load it. The teeth could break out in result and the costs of grinding would double then.
Maximum Cutting Dimensions
Maximum dimensions in mm – see the table of section shape with regard to the defection angle. The angle
of 90° should be understood for straight cutting.
