(1) using insert radius 0,8 mm Table 2 - Maximum revolutions when balancing with the arbor or chuck has not been achieved: Note: During helical interpolation do not exceed maximum pitch. When using different insert radius to calculate the ØDHmin and ØDHmax use the equation below:

ØDc Ø32 Ø40 Ø50 Ø63 Ø80 Ø100 Ø125 - Minimum Diameter: ØDHmin = 2 x (ØDc - (R corner radius + F width of edge wiper)

- Maximum Diameter: ØDHmax = 2 x (ØDc - R corner radius)

- When setting the spindle speed, take into consideration the maximum allowable revolutions of arbor or chuck. - Use the specified set bolt when using the arbor type with internal coolant supply.
