Centroid "Oak" closed loop CNC Controller.
A reliable, high performance, industrial quality CNC control at a do-it-yourself price. The Oak utilizes an integrated Motion Control CPU and communicates with CNCPC via a fast and reliable Ethernet connection.
The Oak is a 4 axis CNC control board that is expandable to 8 axis of simultaneous motion. Perfect for many types of machine tools such as: CNC milling machines of all types, Turning Centers and a wide variety of CNC routers and other specialty applications. Typically used on CNC machine tools where a high performance CNC control is needed. Typically used with AC brushless servo in full closed loop operation but also can control DC servos as well. Yaskawa and Delta are recommended servo drive packages for use with Oak but, many others can be controlled by the Oak cnc control board as well. The Oak runs on Centroid proven industrial quality Mill or Lathe CNC control software.

Menu driven Probing Cycles with DP-4 Probe
Centroid Probing cycles are used to make part setup faster and more accurate with less work. Easily find centers or bores, corner of parts or vise in seconds with fantastic accuracy. If your shop is always tearing down and setting for different jobs Centroid Probing pays for itself in a very short time. Centroid's probing package includes the Centroid DP-4 probe, the Centroid menu driven probing cycles and Coordinate System Rotation. The Centroid menu driven probing cycles are as follows. Bore, Boss, Inside Corner, Outside Corner, Edge, Slot, Web, Single Axis.see the
Centroid Probing brochure
Menu driven Digitizing cycles with DP-4 Probe
Centroid Digitizing Cycles are commonly used to copy 2D or 3D shapes and contours of an existing part. Commonly used for reverse engineering the Centroid digitizing data can be exported to a cad cam system for further geometry manipulation or run as a G code program immediately. see the Centroid Digitizing Brochure
Menu driven Automatic Tool Measurement with TT-1 probe
Set up 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 setup 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. Requires conductive tooling and spindle. Download TT-1 brochure click here.
Menu driven Automatic Tool Measurement with TT-2 probe
Operates exactly like the TT-1 but this design is mechanical in nature. The TT-2 works with all types of tooling and spindles. The non-conductive mechanical design is compatible with machines that have non-conductive ceramic spindle bearings and with all types of tools such as non-conductive diamond tooling. Backward compatible with most CENTROID CNC controls that have a black probe plug (cnc7,cnc10 and cnc11 based systems). Uses same cable and connectors as our DP-4 and DP-7 probes. There are three base mounting options: magnetic, screw down or tool holder. The Carbide surface is also replaceable and has a 4-48 thread. Download TT-2 brochure click here.
Oak CNC Software Options
Unlimited G-code program size
Standard G-code program size for Oak CNC control system is 4Mb which is more than enough for most shops. However, if large complex 3D or 5-axis G-code programs are being run, they can exceed the 4Mb file size so that's where the Centroid Unlimited G-code program files size option come in
CENTROID's advanced rigid tapping cycles are simple to program through G-code, Cad/Cam or Intercon. In Intercon, you get an extra cycle called Deep Hole Rigid Tapping, (see a video here) Deep Hole tapping taps a hole much in the same way as you would by hand. It backs out of the thread to clear the chips and then matches right back up with the new threads and continues the tapping. Another advantage of deep hole tapping is that it allows you to tap a much larger hole than the HP of your machine would normally allow.
BCD Tool Change output
Allows the command and control of a Automatic Tool Changer such as a Swing Arm or Umbrella Type Tool Changer.
Scale Feedback for servo motor positioning
Allows the use of precision glass scales for machine/servo motor positional feedback. Typically used on large high performance machine tools. (not to be confused with Scale Feedback for DRO position display of a manual axis which is included with base level Centroid CNC software)
C axis software
Allows the command and control of C axis functionality on a Lathe
Advanced software servo motor pairing
Software Axis pairing allows any two axis to be paired within Centroid CNC software and supports advanced homing, squaring and syncing feature set for axis pairing.
5+ axis simultaneous cnc software
Allows 5 axis, 6 axis simultaneous interpolated motion.
Note: 4 +1 (or any other combination not using 5+ simultaneous motion) is included in the Oak CNC software.
5+ axis is US Government controlled technology and any sale is governed by Department of Commerce regulations and requires export paper work.
Extended Multiple Work Coordinate Systems (WCS) G54 P1-P12) G54-G59 is included, this option adds 12 more individual WCS positions for a total of 18.
