What Is a Colombo Multispindle Unit? A Colombo multispindle unit is a multi-output assembly — typically a single head or housing containing multiple spindle shafts arranged to perform repetitive drilling, boring, or routing operations simultaneously. Each output shaft carries its own bearings and tooling interface. The shafts share a common housing structure, and depending on…

(Fixed-Tool High-Speed Spindles for CNC & Specialty Applications) Giordano Colombo manual electrospindles are high-speed, fixed-tool spindle units commonly used in CNC routers, edge-processing machines, specialty machining centers, and aggregate heads. Unlike automatic tool-change (ATC) electrospindles, manual versions use collet-based tool holding (typically ER collet systems) and are designed for dedicated tooling setups. These spindles are…

What Is a Colombo Automatic Electrospindle? A Colombo automatic electrospindle is a self-contained machining unit that integrates the motor, spindle shaft, super-precision angular-contact bearing system, automatic tool-change mechanism, cooling system, and sensor hardware into a single assembly. Tool changes happen without manual intervention — a spring-loaded drawbar driven by pneumatic or hydraulic actuation clamps and…
