y Speed n [rpm] as a function of  x Circular saw blade diameter D [mm]
1 Maximum operating speed | 2 Recommended operating speed

The feed rate vf for mechanical feed is calculated using the following formula:

vf = n × Z × fz / 1000

Z: Number of teeth | n: Speed | fz: Tooth feed rate

Recommended for HPL: fz = 0.03 – 0.06 mm
