NSK E3000 Series Electric Spindles

With the E3000 Series, the spindles are available in both single motor/spindle combinations and also modular type where the spindle and motor are separate units screwed together. The diameters available include 1.18", 0.98",0.897, 0.79" (30, 25.4,25,22.8 and 20mm).

A motor can be rotated within the range of 5,000 rpm to the maximum output rating of the motor in increments of 1,000 rpm. Motors are available in speed ranges of up to 60,000 rpm. This option requires the purchase of a control unit and selector unit that supply power and cooling to the motor mounted to the gang tool plate. The Astro E-3000 control has the capability of controlling four spindles, each with a unique speed setting. The spindles cannot be operated simultaneously. The addition of a communication cable is required if the operator desires to control spindle start/stop from within the part program.

The table below illustrates a partial list of choices available. In "Description" of motors: 350W = 350 Watts (Power) "60K" = 60,000. Spindles come equipped with a 1/8" collet and chuck nut and two wrenches with many other sizes available. All NSK live tooling systems include the spindle and a motor. The spindle contains the collet chuck that the cutting tool mounts to. Reduction gear units are available for electric spindles to increase cutting torque. When mounted, the reduction gear slows the rotation of the spindle proportionally. They are available in up to 16:1 ratios. The use of a reduction gear will increase torque allowing for more aggressive cuts than possible when using only a spindle and motor. CNC New, Inc. provides tool holders that allow installing spindles in axial, radial, or vertical orientations. This is a partial list of the many options available from NSK for the E3000 series electric spindle option.
