Industrial Electronics Repair for CNC Machine Shops
Roughly a third of the CNC machines in service are over 15 years old, and the electronics fail long before the iron wears out. FANUC amplifiers, Mitsubishi MR-J2S drives, control power supplies, and operator displays are our daily work — shipped in from shops nationwide, repaired, tested, and returned with a 24-month warranty.
