Repair by equipment
Repair of Spindle Motors
High-speed motors for machining and cutting.
Symptoms
What brings this equipment to the bench
If the machine's behaviour matches one of these, the diagnosis will sort it out. None of them requires the manufacturer to still support the line.
- Bearing noise or axial play
- Loss of speed under load
- Overheating in continuous duty
- Speed sensor with no reading
Bench scope
What TECSI does on Spindle Motors
- Disassembly with prior measurement of axial and radial play and a record of runout
- Replacement of precision bearings (angular contact) with the preload and lubrication specified by the manufacturer
- Dynamic rotor balancing for the working speed
- Insulation and winding resistance testing; rewinding when required
- Repair or replacement of the encoder or speed sensor and of the cooling system (air or liquid)
- Recovery of the tool holder taper (HSK, BT, ISO) and of the collet and unclamp system
- Replacement of oil seals and recovery of the labyrinth seal
- Speed ramp test up to rated speed, measuring vibration, temperature and current
Whatever cannot be recovered is stated in the report, before the quote.

Repair
How the equipment goes through the workshop
The same process applies to every brand and every piece of equipment. Nothing is carried out before the quote is approved.
- 01
Intake and identification
Entry record, photos of the condition on arrival and identification of manufacturer, model, serial number and firmware version.
- 02
Diagnosis and report
Bench analysis of the fault, testing the input, power, control and feedback stages. The report identifies the root cause, not just the burned component.
- 03
Quote
Customer approval before any intervention. An unrecoverable part or an economically unviable repair is reported as such.
- 04
Repair
Component replacement with new or approved equivalent parts, solder rework, technical cleaning and insulation restoration.
- 05
Functional test under load
The equipment is tested under real operating conditions, not merely powered up on the bench.
- 06
Burn-in and release
A continuous test period before return, accompanied by the technical report of the work performed.
- 07
Warranty
Warranty on the work performed, with technical support after the equipment is returned.

Frequently asked questions
Do you repair Spindle Motors of any brand?
Yes. Spindle Motors repair is multi-brand and covers discontinued lines, with a spare-parts stock of IGBTs, encoders, and resolvers, including for what is out of production.
How long until I get the quote?
Within 12 hours of receiving the equipment, with the diagnosis and commercial proposal detailed before any work begins.
Do I have to stop production during the repair?
Not necessarily. While we repair yours, we lend an equivalent unit so production keeps running, at no cost. There is emergency service outside business hours, on weekends and holidays, for a stopped line.
Are the assessment and the repair guaranteed?
The technical assessment is free with no obligation to proceed. Once repaired, the equipment comes back with a warranty and post-repair technical support.
