HSD
Spindles

HSD is an Italian manufacturer of high-speed electrospindles widely used in CNC machines for wood, metal, plastics, and composite materials. They are known for high precision, compact design, and outstanding reliability. These spindles can be found in machines from manufacturers such as Biesse, SCM, Homag, and Felder.

Despite their high quality, HSD spindles – like all mechanical devices – wear out over time. The most common faults include worn bearings, speed sensor problems, overheating, and rotor damage. Precision refurbishment with correct geometry and dynamic balancing is crucial to restore the spindle to full working order.
