The Okuma Mechanical Exchange Division makes high quality recertified parts available at a fraction of the cost of new parts. If a spindle goes down, no matter the reason, simply contact your Okuma distributor for a replacement spindle or cam box and return the defective one in the packaging provided. Your defective mechanical device will be recertified by Okuma technicians using OEM replacement parts and added to our extensive stock for the next customer. All exchange parts are guaranteed for 12 months when installed by a qualified Distributor or Okuma technician. You can be back in action in just a few days, not the two to three weeks common with third-party rebuilders. Okuma Spindle & Cam Box Exchange supports technology for every Okuma machine ever produced.
