CAD to CNC right at the control.  DXF file import. Create G code from your CAD files. CAD to CNC, DXF file import with Intercon Conversational.
Convert DXF files into G code with CENTROID's Intercon conversational programming software. NO CAD/CAM system necessary. Fast and simple, this new feature allows you to create parts directly from a CAD file on the control or on your desktop PC. You can even combine any or all of your CAD file with any conversational events. This is the most flexible way to take advantage of both CAD/CAM like programming with the simplicity of conversational. With a fast learning curve anyone can be producing money making parts from a DXF file in short order. This new feature saves you both time and money, less expensive than a CAD/CAM system, much easier to learn with faster results.

Rigid tapping.  Easy to program canned cycles just fill in the position , depth and threads per inch. Rigid tapping, Deep hole tapping and Threadmilling
With a CENTROID M39 you can make all kinds of threads.You can use Tapping, Rigid Tapping and Threadmilling depending on your part for the best result! CENTROID's advanced rigid tapping is simple to program and will both tap a hole in the regular way AND can also use the deep hole cycle to make a large diameter thread. Deep hole tapping taps a hole much in the same way as you would by hand. It allows you to tap a much larger hole than the HP of your machine would normally allow!
CENTROID's own DP-4 digitizing touch probe.  Copy any 2D or 3D shape. Directly creates G codes for you.   Digitizing. Turn your milling machine into a copy machine.
Copy and Cut 2D and 3D shapes. Centroid's affordable, effective Digitizing is the simplest CNC Digitizing on the market. Just record and play back. Do you have a 2D contour such as a CAM or a 3D part like a mold or plug? But no print? Let our Digitizing feature copy the part for you. Digitizing turns your milling machine into a copy machine. Centroid has overcome the cumbersome problems associated with Digitizing on other controls. With a Centroid, it's actually one of the simplest features on the control to use. With our Digitizing feature you will be able to copy and reproduce an existing shape with little or no programming! No CAD/CAM necessary, however you can export the Digitizing information to a CAD/CAM system for further modification. It's very popular for repairing cylinder head combustion chamber damage, copying cams, creating molds and plugs from existing objects and many other uses. more...
Automatically set tool offsets. Fast simple and VERY accurate. Saves time every setup. Auto tool set
Setup your tools in a quarter of the time it would normally take! If you often machine short-run parts and are always setting up and tearing down for a new job, the TT-1 Auto tool set will save you tons of time while more accurately setting your tool height offsets. With the TT-1 you can create more parts per hour since the tool set up is so much faster. You'll even save time when you have to replace a dull tool with a new one in the middle of a job. The TT-1 is completely automatic. Press "measure" and the tool will automatically touch off the TT-1 and set the tool height offset in the tool library. See the TT-1 in action on our Video CD. The TT-1 plugs into the control...
