The CENTROID CNC control can operate a wide variety and types of tool changers. Umbrella type to Swing arm -- the Centroid provides fast repeatable tool changes. Automatic batch measurement is also available when used with our TT-1 Auto Tool Setter. Just highlight the tools you would like to measure and the batch feature will automatically retrieve, measure, and replace each tool automatically.

cnc digitizing 2d and 3d

CNC 2D and 3D Digitizing

• Duplicate parts in 2D or 3D
• Easy menu-driven fill-in-the-blank digitizing cycles
• Perform grid, radial, contour & wall following digitizing
• Automatically generates G-code and Cloud Point Data
• Export data to most any CAD/CAM system
  for further editing and shape manipulation
• Autonomous cylinder head port & combustion digitizing
• Probe and Software designed to work together
• DP-4 all around .0001" accurate 3D touch probe
• DP-7 specialized long styli application touch probe

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.

auto tool measurement

Automatic Tool Setter

• Effortlessly measure tool heights
• Repeatable results for consistent part production
• Faster and more accurate than manual methods.
• Significantly reduce setup time
• One-touch operation sets tool heights within 0.0001” in seconds
• Menu-driven automatic tool measurement
• TT-1 conductive, TT-2 non-conductive probes

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, Auto Tool Set will save you tons of time, while more accurately setting your tool height offsets. With the TT-1 or Tt-2 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. Auto Tool set is completely automatic. Press "measure" and the tool will automatically touch off and set the tool height offset in the tool library. .
