(High-Production CNC & Routing Applications) Giordano Colombo multispindle units are engineered for high-production CNC routing, drilling, and panel processing systems. These assemblies integrate multiple spindle outputs within a single housing, allowing simultaneous drilling or routing operations — dramatically increasing throughput in woodworking, furniture, and panel manufacturing environments. Unlike single electrospindles, multispindle heads introduce alignment, balance,…

(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…
Read MoreGiordano Colombo Automatic Electrospindles
Giordano Colombo (Colombo) is known worldwide for high-speed automatic electrospindles used in CNC routers, machining centers, and specialty production equipment. Their automatic tool-change (ATC) electrospindles are engineered for high RPM capability, compact integration, and reliable industrial duty cycles. These spindles are common in woodworking, composites, plastics, aluminum machining, and nested-based manufacturing environments. What Is an…

(High-Speed Vertical Machining Centers • 10,000–20,000+ RPM) BT40 spindles are common in high-speed vertical machining centers where balanced toolholders, consistent taper contact, and stable thermal behavior are critical. Many BT40 cartridges use SKF super-precision bearing systems, typically from the 70xx or 719xx (often hybrid ceramic) series. Atlanta Precision Spindles rebuilds the spindle assembly only, restoring…

(Vertical Machining Centers • 8,000–15,000+ RPM) Many CAT40 Vertical Machining Centers use SKF super-precision angular contact bearing systems inside integrated spindle cartridges. Whether configured with 70xx steel bearings for rigidity or 719xx hybrid ceramic bearings for higher RPM, these spindles rely on precise preload, clean lubrication, and accurate balance. Atlanta Precision Spindles rebuilds the spindle…

High-Speed Cartridge Systems for CAT40 • BT40 • ISO30 Machining Centers Many Vertical Machining Centers (VMCs) use SKF super-precision bearing systems inside integrated spindle cartridges. Whether configured with 719xx hybrid ceramic bearings for higher RPM or 70xx steel angular contact sets for added stiffness, these spindles depend on precise preload, clean lubrication, and accurate balance.…
Read MoreSKF spindle overheating
Overheating in an SKF-equipped spindle is never random. Whether your spindle uses 719xx high-speed hybrid ceramic bearings or 70xx steel super-precision sets, heat rise is typically the first sign of preload imbalance, lubrication breakdown, contamination, or internal friction. In high-RPM VMC and grinding applications, small changes in preload or lubrication can amplify rapidly. Atlanta Precision…
