Circular Saw Terminology
Tungsten carbide tipped saw blades should run between 40 and 60 m/s depending on the material being cut.
Plate saws should operate at 50 m/s, swage or taper saws at 60 m/s.
Inserted tooth saws are tensioned to run at a maximum rim speed of 40 m/s.
Speeds of 100 m/s and over are for hot and cold cutting of steel.
TENSION CAN BE ALTERED TO SUIT YOUR APPLICATION SO PLEASE SPECIFY THE SPEED OF YOUR SAW OR ASK FOR ADVICE.
Using the formula for circumference and the RPM of your tool you can easily deduce that a 750mm 96tooth saw blade attached to a machine with 2600RPM motor will run at a speed of:
C x RPM = m/min
2.355m x 1230rpm = 2896.65 m/min
so to get to seconds you would need to divide answer by 60.
meaning 750m diameter TCT blade would run at a speed of 48.2775 m/s
The angle at which the teeth will primarily engage the material being cut ,
is in short the hook angle.
The more positive the hook angle means the more aggressive bite the saw will take on the material
a lower or more negative hook angle causes each tooth to take a less aggressive bite.
Our choice of tooth geometry depends highly on the material you are cutting as well as the finish you require.
A combination of angles and tooth forms have been tested and applied to different material allowing us to form the tooth and sharpen it with the correct angle. This will make a difference to the edge quality of your material whilst improve longevity of you sawblade.
