Available from Southwestern Industries, ProtoTrack CNC retrofits are suited for toolroom knee-mill productivity and small-lot work. The easy user interface of the CNC differentiates it from production-oriented CNCs, the company says, adding that geometry-based programming is intuitive to machinists and useful for those who have limited exposure to G-code programming. Retrofits are installed in the customer's shop in about a day by a factory-trained technician.
Other features include networking, spreadsheet editing, list step graphics, an auto geometry engine and DXF converters.
