This hands-on mechanical drives training system uses industrial linear roller bearings, which are designed to handle the high loads encountered in CNC machine tool units and accurately track the axis. The Roller-Pack Machine Tool Axis training includes a precision machine tool axis that uses 12 of the linear roller bearings to provide accurate axis movement, and it is designed so it can be assembled and disassembled in a manner typical of how industrial machine tools are serviced. It is also designed with a full complement of adjustments including gibs, both tapered and flat, for each bearing. With these features students receive real-world experience changing bearings and making the critical adjustments necessary to provide precision movement.
