Stages of a M-39 CNC Retrofit of a Shizuoka Knee mill

Here is a Shizuoka model AN-S 3 axis NC mill, This rugged and very popular knee mill was originally equipped with a Bandit control. This machine is in good mechanical condition but is equipped with an old obsolete NC control.
With control parts becoming scarce and repairs more frequent, it was time to upgrade!

The M-39 is a lower cost Centroid package, You supply the monitor and standard PC keyboard.
Centroid supplies the axis motors, amplifiers and CNC PC, prewired NEMA cabinet and hand held push button pendant.

Your local Centroid representative will come to your shop and evaluate your machine and spec the right Centroid CNC for the job.

This is what you can expect when your control arrives. Centroid controls are not just a few computer parts in a UPS package.

Centroid CNC Controls are completely factory assembled and come ready to install on your machine.

The electrical enclosure of the M-39 is: 24" wide X 36" tall.
The axis motors are pre-wired with MS type plugs or can be hard wired.
CNC manual, hook up wiring diagram, and training video.

Hand held M-39 control pendant.
Mounting hardware for monitor/keyboard shelf.

Everything you will need
right down to the nuts & bolts.

First step was to remove the old
control and motors.
Time: 1 hour

Next, Mount each axis drive motor.
Mount the electrical cabinet.
Mount the monitor / keyboard shelf.

Time: 2.5 hours

Just plug in the motors, monitor and keyboard.
We also wire in the machine limit switches, secure the cables, and wire tie any bundles for a first rate installation.

At this point we will enter a couple of values for each axis and then one button will auto-tune each axis driver. Our installations includes checking your machine accuracy, setting the back lash values, and training your machinist to use this new tool.

Optional features such as TT-1 auto tool length measurement or network communications can be added now or in the future.

Time: 4.5 hours

Total time for install on this Shizuoka model AN-S knee mill retrofit is 8 hours.

Centroid CNC training is typically held the next day and is also 8 hours.
