– Siemens 840 Series –


CNC Machine Services is pleased to offer and drives retrofits for all the machines that we service. We can replace your old controls with Siemens 840 Series control and drives.  This brings new life to your older CINCINNATI MILACRON machine or lathe.

Old Acramatic 900 Control…



The Siemens 840 Series control is PC compatible, runs on Windows base, and can be networked to your system. With the 840 control you can use your existing spindle and axis drives and you can update your drives at a later date. We can install digital scales to increase the accuracy and repeatability of your machine.

We can add that fourth axis that you have always wanted, which will give you more flexibility to machine more of the part with a single setup.


Are you still punching paper tape?  We can supply and install Greco Company products to your control which will eliminate tapes and let you make programs on your PC using a standard word processor or CAD/CAM.  We can also convert your control memory load tapes to disk which can be loaded through the Greco unit.
