The CENTROID DP-4 CNC Touch probe is designed for Probing (part setup, zero location setup, and CMM type location and measurement of part geometry), component/fixture/work piece setup, inspection and 3D or 2D digitizing/surfacing. The DP-4 CNC Touch probe is made in the USA with patented technology. Manufactured of stainless steel the DP-4’s mechanism requires only a feather’s touch to trigger. The DP-4’s low trigger force allows the use of small styli for maximum detail and accuracy. Commonly used on Milling machines, Machining centers, Routers and Turning centers. The DP-4 is a state-of-the-art mechanical design and is compatible with most CNC controls and DRO’s that have a PLC input for probes and probe software. The CENTROID DP-4 is reliable and is an affordable alternative to Renishaw or Marposs touch probes. Previously sold exclusively for use with a CENTROID CNC control, now the DP-4 is available for use with other CNC controls and DRO’s such as Fagor, Haas, Fanuc, Fadal, Mazak, Mach3 and many more.
