Independent Shops for Okuma CNC Repair

This directory lists independent repair shops for Okuma spindles, MIV drives, power supply units, and control boards. A listing shows the shop’s Okuma repair categories and the turnaround and warranty terms that the shop publishes.

On an Okuma machine the drive, motors, encoders, spindle, and CNC control all come from Okuma. Okuma developed its own numerical controller in 1963 and calls its control line OSP. Independent drive repair shops list Okuma MIV servo drives, MIV spindle drives, and MPS and MPR power supplies.

Okuma Repair by Component

This directory splits Okuma repair into separate pages by component. Each page explains the faults for one component and the checks that Okuma manuals and service articles list ahead of a repair. The shop list on each page narrows the directory down to shops listed for that component.

How Power Reaches the Spindle and Axes

Okuma’s Motion Control System (MCS) runs on two kinds of drive units. A DC power supply unit supplies 300 VDC and 24 VDC control power to the MIV units. MIV units are the inverter units that drive spindle motors and axis drive motors.

The MPS power supply unit uses power regeneration and goes on systems with a spindle drive motor. On systems with axis drive motors only the MPR unit uses resistor regeneration. MIV units take commands from the NC over the servo link and communicate with the encoders over the encoder link. The power supply unit connects to the MIV units through the converter link.

Back Up the Control Ahead of Any Repair

Okuma ships each machine with its NC software media stored inside the control cabinet. That media runs from paper tape on the OSP2200 to DVD on the OSP-P300. A machine that loses its memory without that media could sit down for roughly 1 to 5 days while Okuma schedules production of Duplicate Software.

Part programs, tool data, parameters, and ATC locations stored in the machine need timely backups. Okuma suggests making that backup part of the preventive maintenance cycle. On the OSP-P500 alarm 0945 MEMORY BOARD/BATTERY LIFE means the UPS battery is near the end of its life at about six years. All parameters in the control could be lost if that battery reaches its end of life without a replacement.

Using This Directory

Listing details come from information published by each shop or sent in by the shop owner. Shop owners can request a new listing or send a correction to an existing listing through the forms on this site. Each listing links to the shop’s own website and phone number for quotes and shipping instructions.

CNC Machine Pros does not perform repairs and takes no part in the quote, repair, or warranty between a shop and its customer. Each shop sets its own prices, turnaround, and warranty terms and handles its own repair work. Questions about a quote, a repair, or a warranty claim go straight to the shop handling the repair.
