NOTE:
(1) All conditions described above are based on the use of high speed steel saw blade.
(2) The workpiece is 150 mm round and solid, normalized heat treatment, and there are no
hard spots in the material.
(3) The cutting surface concave or convex by 1.0mm is permitted.
(4) The indicated service life of a saw blade stated is based on an average value spread over
results from 10 saw blades.
(5) The selection of a correct blade for any one type and size of material being sawn is largely
dependent upon trial and error until the desired conditions are fulfilled, i.e. finish cutting
time ,blade life, etc. However these charts are offered here for the guidance of users so that
these conditions may be obtained.
