Spindles assure quality surface finish
High speed aerostatic (air bearing) Colibri 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/um, a radial stiffness of 8N/um, a speed of 80,000rev/min, and very low run out (0.2-0.5um)

Motorised bearing technology the next generation
A novel technology for the design and manufacture of spindles enables the integration of significantly enhanced air bearings.
These compact, advanced technology, "motorised bearing technology" (MBT) spindles can be used in a vertical or horizontal positions, and are raising the standards of surface finishing.
The compact (80mm diameter, 195mm long), 1050W Colibri ZAL Series spindles produce up to 0.125Nm of torque.
Incorporating Colibri's "motorised 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 (eg 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.
