CNC Service and Spindle Overhaul
CNC.arc is a service provider specialized in CNC machines, based in Gothenburg. The company offers mobile on-site service in Sweden, Norway and Denmark: troubleshooting and repair of mechanics, electrics, drive systems and controls, 24/7 emergency service during production downtime, as well as preventive maintenance and maintenance outsourcing with a customer portal. In its own DoctorSpindel workshop in Brzezia Łąka near Wrocław, spindles and removed components are overhauled – with a lathe, surface grinder, and cylindrical and internal grinding machine from Fortuna, plus an in-house spindle test station. Further services include FANUC control diagnostics, geometry measurement and ballbar tests (Renishaw QC20-W), vibration analysis with SmartBalancer, retrofit and modernization, ball screws and linear guides, CNC training, and machine relocations including disassembly, transport, alignment and commissioning. Referenced is the relocation and measurement of five five-axis GROB G550 machining centers in aerospace manufacturing. Experience is documented with machines from DMG MORI, Haas, Mazak, Okuma, Hermle, DN Solutions/Doosan, Hwacheon and GROB as well as controls from FANUC, Siemens and HEIDENHAIN. Communication is conducted in Swedish, English, Polish and German.
