Okuma Howa 438 spindle repair solutions

Our customer acquired several Okuma Howa machines from a sister plant that closed. The installation of the machines was anything but smooth.

Mazak VTC200B 12,000 rpm 40 taper Oil Mist Lubrication This customer has multiple Mazak VTC200B machines in their facility that were experiencing frequent spindle failures. We disassembled the first spindle and found that the design was very poor. The nut for the rear bearings was hydraulic and had the long shaft that attaches to the drive motor bolted to it. The problem with this setup occurs if there is any misalignment with the drive motor, any vibration in the drive motor or if any number of ground surfaces are not virtually perfect. Any flaws in these areas subjects stress directly to the rear bearing causing premature failure.
