Common Repair Issues

HSD Balance Screw

HSD’s have balance screws in two places, at each end of the rotor. These reside directly under the stator windings. These screws can come loose over time and rub against the windings.

915 Rear

HSD spindles have a drawbar end that looks like this. Over time the drawbar can wear out the guide bushing. This will open up the clearance for the guide and the vibration will increase exponentially.

What We Do

About HSD Spindles Repair

Schedule a Repair Appointment Today!

HSD Spindles are the most common type of spindle we repair. The cost of repair is usually less than the cost for a cartridge replacement. Also, the end result of a rebuild will have better vibration. Some HSD spindles have a critical speed below 24,000 rpm. Most HSD spindles will have a different level of vibration at 18,000 vs 24,000 rpm because of the critical speed.

Common Models We Repair

Warranty

All spindles have a one year warranty on the work performed. Our warranty is the same as the factory on work performed. All warranty labor is free.

Directly from HSD’s Manual1.12 Guarantee Conditions

HSD S.p.A. guarantees that the electrospindle has been inspected at its plant with a positive result.

Works under warranty shall be performed free at the HSD S.p.A. facilities, transport at the customers expense; HSD S.p.A. shall not be liable for termination of production during the warranty period.

The warranty does not cover faults due to normal wear of those parts which, by their nature, are subject to rapid and continuous wear (e.g. gaskets, belts, bearings, etc.). In particular, HSD S.p.A. gives no guarantee as to the working life of the bearings, as this depends on various factors including the degree of balancing of the tools, the types of machining operation, collisions and/or mechanical stresses beyond the values indicated by the manufacturer.

Free Inspection

Spindles sent to HS Spindles are inspected for free.
