Technical Guide – Power Curve
GC Electric Spindles are available in either Constant Power or Constant Torque. Both types offer advantages depending upon the operating speed for the cutter(s) used in your application.
- CONSTANT TORQUE electric spindles suit application where maximum cutting power is required near maximum spindle speed. Their torque is constant, so power increases steadily from zero at zero speed to full power at full speed.
- CONSTANT POWER electric spindles provide flexibility for a wider variety of cutting tasks. They deliver more power at mid-range speeds but less power at maximum speed than constant torque spindles. Typical constant power ranges are 9000 – 18000 rpm, 12000 – 18000 rpm or 18000 – 24000 rpm. The selection depends upon the operating speed for the cutter range & material type.
