Ekstrom Carlson repairs and rebuilds DFA-ASI spindles and live tooling to OEM performance standards — including milling heads, angle heads, and turning attachments. Our technicians service DFA-ASI 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.
Our Process
Full disassembly, bearing inspection, housing measurement, and root‑cause analysis. You receive a written evaluation before any work begins.
Bearing replacement, shaft re‑grinding, taper restoration, seal replacement, and housing repair — using components matched to OEM specifications.
Dynamic balancing, thermal testing at operating speed, and run‑out verification. Every spindle ships with a documented test report.
