Automatic Rotary Four-Pallet Changer

MIDACO Corporation (est. in 1969) continues to expand its automatic pallet changer line with the introduction of a four-pallet system on one shuttle.

"Whether running high volume production of the same part or programming several different set-ups, the Automatic Rotary 4-Pallet Changer can be loaded and scheduled to feed your new or existing VMC for multiple hours of unattended machining, extending operator walk-away time and maximizing productivity," said a company spokesperson.

This shuttle's pallet carrousel provides a full 360° rotation, allowing all four pallets to be conveniently accessed from flip-panel stations located on two sides of the pallet changer. Easily load and unload heavy parts (up to 2,000 lbs. capacity per pallet on largest model) with a crane or robot without any overhead obstruction.

Once a job cycle is complete, pallets will rotate automatically on the shuttle carrousel, and the pallet changer's servo drive transfers the next pallet onto the cast-iron receiver mounted directly onto the machining center table. Durable precision ground steel rails and hardened locating pins/bushings provide +/- 0.0001" (0.0025 mm) repeatability.

The system is equipped with a two-sided light-curtain guarding system via light emitters, mirrors and sensors. A pallet change will not occur if the invisible light beams surrounding the shuttle system are breached, meeting CE compliance.


  • One servo drive shuttle system with automatic door and light curtain
  • Four cast aluminum or cast-iron pallets in XY sizes up to 50" x 24" (1,270 mm x 609 mm)
  • One cast iron receiver with up to 2,000 lbs. (908 kg) weight capacity per pallet on largest model (with weight evenly distributed)
  • Control panel is fully integrated with the VMC via M-codes.

"Increase performance during a regular shift or during lights-out manufacturing with only a skeleton crew maintaining the production," said the spokesperson. "Mounting parts onto pallets outside of the machine tool while other parts are being machined reduces wasted time and cost of part changeover, which forces the machine to be idle. Once the parts inside are complete, the pallet changer automatically switches the pallets in seconds and the next batch is ready to go. Quote more competitively by saving money with increased spindle utilization during the machining process and get more parts out the door. The idea is to keep the machine spindle running."
