Simple, reliable operation. With the 440A BTR, part programs are stored on computer disk and may be load or run directly from the computer, reducing both setup and programming time. Punched tape is completely eliminated, along with the associated storage, handling and maintenance problems.Easy to install and use. The 440A BTR is installed inside the NC cabinet and connected to the NC's tape reader port. This means that virtually any NC with a tape reader can be easily upgraded for direct program and executive loading as well as drip feeding.
Reader and puncher emulation. Bi-directional transfers are supported for NC/CNC machine tools equipped with both a tape reader and tape puncher port. In addition to loading files into the CNC memory, edited programs may be saved back to the computer.
