Spindle Repair & Rebuild Services
COROMANT
SPINDLE
REPAIRED.
Ekstrom Carlson repairs and rebuilds Coromant spindles and live tooling to OEM performance standards — including milling heads, angle heads, and turning attachments. Our technicians service Coromant spindles across CNC lathes, machining centers, and multi-axis turning equipment.
Every repair starts with a full disassembly and written diagnosis. We replace worn bearings, restore tapers, repair housings, and rebuild with precision components — then dynamically balance, run-out test, and thermally verify every spindle before it ships back to you.
