Imagine putting at the tip of your operator's finger...

  • A touch screen so intuitive, fast, and easy to use that it can cut programming and set-up times by 20%...40%...even 50% or more
    on key tasks.
  • A platform that's two controls in one – Conversational and G-Code.
  • A whole new way of programming, including built-in CAM software that allows you to create complex shapes geometry and tool path all in the same feature, as well as convert DXF files into part programs.

Designed from the ground up to streamline programming while reducing operator errors, the Acu-Rite 3500i touchscreen control saves significant time and cuts waste on each and every set-up and production run.

Milling jobs are now as simple as...touch...and GO!

The Acu-Rite 3500i features a flexible touch screen layout that's driven by software designed from the ground up to give operators a versatile array of options. Graphical, one-touch function keys both simplify and accelerate programming and set-up tasks.

The 3500i is two controls in one, Conversational and G-Code. Conversational is programmed in plain machinist language and uses a powerful set of canned cycles to aid in quick and easy to understand programming. G-Code is entered using the on-screen full keyboard or the G-Code help editor. Importing programs is fast and easy via networking and USB.

New Interface
  • Intuitive touch screen interface
  • Custom PLC touch screen buttons eliminate the need for a manual panel
  • Active MDI fields
  • XGA Display (Extended Graphics Array 1024x768 resolution)
  • Text and graphical program preview in Program Manager
  • Program preview in editor
  • Full support for conversational and g-code programming
Easy to Learn, Intuitive to Operate

At the heart of the Acu-Rite 3500i's versatility is its touch screen interface and the innovative software driving the interface. Menus and function keys are integrated into the borders of the high resolution, 12.1" XGA screen. Floating numeric keypads are easily dragged to the operator's preferred position

Innovation – Coarse Tool Support

When a coarse tool is defined, the control knows what that tool can cut, removes that material first and leaves the remaining material for the fine tool. (In the image above, the PURPLE shows the coarse tool path and the GREEN indicates the fine tool path.)

Tool Life Management Support

The 3500i gives the operator control of tool life; a run time for each tool can be specified, and once the run time has been reached, the control will call the specified replacement tool. All this is controlled by the tool page.


Acu-Rite 3500i Control Kits for Retrofit Systems...

Acu-Rite 3500i Retrofi t Kits are available for both new and older models of the most common knee mills and bed mills.

The Acu-Rite 3500i is ideal for retrofitting existing milling machines, elevating accuracy and expanding the types and complexity of jobs they can run. Kits for 3-axis and 4-axis systems are in-stock for most brands of knee mills and bed mills.

Typical kits consist of servo motors, drive assemblies and the ball screw, plus the 3500i touch screen control. Quill drive assemblies are also available.

Complete retrofit packages – as well as control-only kits, with standard analog drive interface – are available.

Boost the productivity, accuracy and capabilities of your existing mills with the easy-to-learn, touch screen efficiency of the Acu-Rite 3500i.

...plus Kits for New Machines

Acu-Rite 3500i Integrated CAM / DXF –
Shifting Cycle Programming to Hyperspeed

When using Acu-Rite's CAM programming tool, all part geometry is generated without the need for machine code. Shapes created are saved as DXF files. The DXF format provides two major advantages for the programmer. First, users can re-edit the geometry in their own CAD system. Second, DXF conversion is uniform across the board – for both imported DXF files and those created on the Acu-Rite 3500i.

CAM Highlights
  • Import and create DXF files
  • Create complete part programs in the CAM editor
  • Graphical definition of contours
  • Chain construction geometry to define contours
  • Create geometry based on definitions of points, lines and circles
  • Toolpath generation commands: contour, pockets, engraving and drilling
  • Smart program generation (cycle based)
  • Direct import of DXF
  • Feeds and speeds calculator

The Acu-Rite built-in CAM software allows you to create complex shapes, geometry and tool paths all in the same feature/screen, as well as convert DXF into part programs.


Once the shape geometry is created (or imported), the Acu-Rite 3500i CAM allows the operator to generate tool path, islands, engraving and drilling cycles, as well as access many other advanced programming features. These programs are posted as complete, modular G-code programs from within CAM, featuring easy-to-understand menus in machinist language. And being modular, cycle-based programs (unlike typical CAM-generated programs), re-editing is much more intuitive and efficient with the Acu-Rite 3500i.
