The first step to securing funding is building a plan for your program. Let us help you get started.
A real CNC milling machine plus a fault-setting electrical cabinet — programming, electrical design, debugging, and maintenance training on one lab platform.
The CNC Milling Machine Maintenance Test Bench is built to close the gap between theory and shop-floor skill. It pairs a compact CNC milling machine with a fault-setting electrical cabinet so students can program parts, process workpieces, and practice maintenance on actual machine hardware — not only on a screen.
It is intended for undergraduate and vocational colleges teaching CNC technology. Learners work through CNC system programming, electrical design, installation, debugging, and machine operation on a single, movable training cell.
Unlike a software-only simulator, this is a real machine tool. Students can disassemble, adjust, and operate hardware they will see in industry: high-speed constant-torque spindle, ball screw, origin/limit switch, electronic handwheel, and cooling water pump.
The bench includes optional CNC systems from Siemens, GSK, Huazhong, and FANUC, plus spindle speed-control units, XYZ motion-axis units, and switch input/output units. That mix supports study of control principles, electrical design, and component selection. Modular layout lets instructors match installations and debugging tasks to the curriculum and still mimic industrial process flow.
Note: The catalogue list jumps from Experiment 10 to Experiment 12. Confirm the official experiment set with EMT if you need a numbered lab manual.
