Johnford CNC Control Systems

Most Johnford CNC come with Fanuc controls for reliability and worldwide service. Common features include a 10.4” color LCD display, PCM/CIA slot, USB port, 512KB of memory, a full keyboard and AICC II Contour Control (high speed machining with 200 blocks look ahead).

Also available is an optional data server with high speed processing up to 1000 block look ahead and 3-axis simultaneous movements up to 60,000 blocks per minute. Another option is the Manual Guide i Software which provides access to material libraries, solid modeling animation, automatic graphical prompt-driven programing and a question and answer format to help simplify machine programming.

Some machines come with Siemens controls or Heidenhain controls. Siemens can have LCD screens of 15.1” color, as compared with the smaller 10.4” possible on the Fanuc. Siemens also has ShopMill programming, automatic residual material detection, universal interpolator NURBS and spline interpolation for 3-axis. The Heidenhain has even more sophisticated software options and comes in 2 configurations. One of the configurations is designed for 3-D machining with motion control, 3-D tool compensation, tool center point management, tool radium compensation normal to the tool direction as well as precise interpolation.

Found a Used Johnford CNC? Here’s what you can do before you go see it.

  • Be informed. When you buy a used Johnford machine, you’re going to need to do more research than when buying a new CNC. Start by making a list of your requirements. You should consider the:
    • Types of materials you want to machine – Are the easy or hard to machine?
    • Tolerances you need – Tight tolerances or not?
    • Industries you’ll primarily be serving – How complex are the parts for this industry?
    • Level of production you’ll be running – High volume light-out? Or short runs?
    • Expertise you have available in your shop – Does anyone know the controls or have time to learn?

You may want to buy a similar CNC to a Johnford that you already have, or you may want to look for one that is newer, so you can begin to connect everything via ethernet or Wi-Fi to take advantage of software innovations.

  • Ask for good photos. Zoom up in the photos and look for signs of damage and worn components.
  • Speak with a local service provider who can provide service for the machine or call the Johnford service.
  • Search similar years for the Johnford CNC to see how pricing compares.
  • Get the hours of operation.
  • Ask for the maintenance records of the specific Johnford that you are considering. Repair work isn’t a bad thing, in many cases, it will help you know what been replaced, what hasn’t and if it was done right. Ask for as much documentation as the seller can provide. This will help you in case you have problems at later date and provide you with details for buying parts.
  • Find out if any tooling or other accessories are being offered for sale along with this used Johnford CNC.

Inspecting a Johnford CNC

  • Ask to operate the machine to see it actually run.
  • Listen to the sounds of the axis moving at different speeds
  • Run the spindle at the max RPM.
  • Look at the guards and sensors on the machine. If sensors, switches, wires and hoses all match and look like they match well, that’s an indication of a well-maintained machine.
  • Make parts on the machine if possible.
  • Check the tool-changer or turret. See how well it changes tools at different areas of the tool changer
  • Check the electrical cabinet for anything that looks like “not factory” and ask about it.

  • Ask if the seller can provide the manuals that came with the machine.
  • If possible, ask the owner why he’s selling the machine.
  • Find out what process controller is on the machine. For older machines, the processor may have been upgraded.
  • Review bar feeder options for CNC turning centers and pallet changes for mills.
  • Review chip & coolant management options.
  • Find out the electrical requirements for install.
  • Discuss payment options, you may get a better deal with a cash down-payment.
