There are many great CNC Machine Tool Manufacturers. We seem to see the most OEMs in the field as follows: DMG Mori (DMG / Mori Seiki), Mazak, Makino, Okuma, MAG, Grob, Hardinge, Enshu, Kitamura, SNK Niigata, Hermle, Chiron, and many others. Please let us know what you think are the best machine tools and why. And we will be happy to tell you if we service that model machine tool. Chances are if it is not Makino we have extensive experience rebuilding that oems spindle.
We frequently repair spindles in 1-3 business days in emergency situations. Our in-house machining and grinding capabilities and qualified partners allow us to turn around components fast such as: spindle tapers, pilot I.D.s, front and rear bearing journals, housing bores, draw bar shafts, splines, and many other components needed to be re-qualified or manufactured new.
We understand the importance of decreasing machine down time so we stock precision bearings, seals, o-rings, encoders, and other commonly replaced spindle parts. Our Four Spindle Test Stands are all equipped with variable frequency drives to allow us to rebuild, test run and ship multiple spindles daily.
Makino by far. Absolute precision and rigidity. I have never seen mold tooling come straight off the machine with as good a surface finish as you will with Makino.
