High speed aerostatic (air bearing) spindles are ideal for cutting and polishing optical components as well as dicing, micromachining, and fine milling.
High speed aerostatic (air bearing) Colibri spindles are ideal for cutting and polishing optical components as well as dicing, micromachining, and fine milling.
The Colibri ZAL Series spindles feature an Axial stiffness of 10N/micron, a Radial stiffness of 8N/micron, a speed of 80,000 rev/min, and very low run out (0.2 - 0.5micron).
These compact, advanced technology, "Motorized Bearing Technology" (MBT) spindles can be used in a vertical or horizontal positions, and are raising the standards of surface finishing.
The compact (80mm dia x 195mm long), 1050 Watt Colibri ZAL Series spindles produce up to 0.125Nm of torque.
Incorporating Colibri's "Motorized Bearing Technology" (MBT), in which the armature of the motor functions also as a radial bearing, the ZAL Series spindles are lighter and shorter than conventional spindles.
Because the armature is a large radial bearing, performance in such critical areas such as stiffness and run out are superior to conventional longer, heavier spindles.
The spindles are available with any spindle nose required (e g tapered or with a collet), an encoder, a Coals contactor for precise position of the tool above the work surface, and in-process water injection through the spindle.
Colibri Spindles specializes in the design and manufacturing of aerostatic and hydrostatic spindles featuring the patent pending, "Motorized Bearing Technology" (MBT).
Their spindles are used in micromachining and fine milling, fine drilling, soft and hard-material dicing, automatic semiconductor wafer testing, and spinning of optics or drums for the etching of printing plates using a laser.
