Midaco Pallet System Enables Extended Periods of Unattended Machining

Midaco Corp. showcases its redesigned Automatic 4-Pallet Changer, which is designed for both high-volume production and low-volume, high-mix multi-setup operations, offering versatility and efficiency. Featuring a single shuttle with four pallets, this system integrates seamlessly with both new and existing VMCs up to a 50" × 25" XY travel, enabling extended periods of unattended machining. This capability significantly increases operator walk-away time and maximizes overall productivity.

The system includes four cast aluminum or cast-iron pallets, with sizes ranging from 28" × 15" (711 × 381 mm) and a 500 lbs (226 kg) capacity per pallet, up to 50" × 24" (1270 × 609 mm) with a 2,000 lbs (908 kg) capacity per pallet.

The pallet carousel enables convenient access to all four pallets from two flip-panel stations. Users can load heavy parts using a crane or robot without any overhead obstruction, even during machine operation.

Upon completion of a job cycle, the pallets rotate automatically on the shuttle carousel, and the servo drive seamlessly transfers the next pallet onto the cast-iron receiver mounted directly on the VMC table. Precision ground steel rails and hardened locating pins/bushings ensure repeatability within ±0.0001" (±0.0025 mm).

This redesigned system includes three-sided safety guarding with a Pilz light curtain. The control panel is fully integrated with the VMC via M codes, ensuring seamless operation.

Additionally, Midaco offers a “Dual Automatic 4-Pallet Changer” configuration. This setup features a four-pallet shuttle mounted on both the left and right sides of the VMC, providing eight fully loaded table setups and enabling continuous, unattended machining for multiple operations.
