special heat treatment which guarantees high wear resistance. Owing to the micros porous structure the
cutting oil is transferred quicker into the saw cut. This means longer life before resharpening and less
chance of cold welding. The quality of the saw blade is of great importance. The selection of the correct
pitch depends on the material to be sawn. The selection of the correct pitch and rake angle is of great
importance for the life of the sawblade.
5.2 Selection of pitch and tooth form
If the pitch is too small and the length of the cut too large, the cut material cannot be taken into the tooth
cavity. The chip wi!l get stuck in the tooth cavity, so that it is inactive in case of a second cut of the same
tooth. This can cause the saw blade to jam and break.A pitch which is too large will cause the sawing
tooth to hack as a result of which teeth can break free. For the sawing of profiles it must be taken as a
rule that at least two teeth of the saw blade are in cut.
Fig, 5.01 will help you determine the pitch for the material to be sawn.
Hint
If a short, hard jerk is felt during sawing and the saw starts jolting, do not continue. In such cases it is
almost certain that at one or more places a fine chip has fused away at the flank of the saw tooth.
This causes the saw to be slightly thicker at certain places. Remove the saw blade and remove the fused
material with a fine-grained, high-grade saw file.
Selection of the tooth form
Besides a well selected pitch the following factors, too, are of great importance to facilitate the correct
machining of the material (fig. 5.02)
