Overview
With the option to factory integrate any automatic pallet changer to your machining centers, this automation category delivers flexibility and productivity with as many pallets as you need.

• Enables continuous production and spindle uptime with automated loading and unloading.
• Increases hours of unattended machining.
• Includes storage areas for finished parts.
• Every APC is supported by Okuma Factory Automation 24/7/365.

Single-Level Pallet Pool
Swap finished workpieces with unfinished materials on a horizontal axis. Operators can set up new jobs while the current one is machined, minimizing machine downtime no matter how complex the part(s).

• Fast exchange time with two pallets on the same plane.
• Minimum of 4 pallets; maximum 12 pallets.
• Standardized, ready-to-use systems: single-level pools with more than 6 pallets have linear or transverse availability.
• Construction uses stationary pallet stands and a pallet transfer unit.
• Pallet pool control (PPC) is fully integrated with the OSP control.

2-Level Lifting Automatic Pallet Changer
Designed for medium- to high-volume runs, this automatic pallet changer’s shelves use a hydraulic lifting system to prepare, load, and unload parts. The lift-and-rotate changeover helps handle multi-height pallet positions with higher speed and throughput.

• Minimum of 5 pallets; maximum 23 pallets.
• Lifting pallets vertically enables rapid pallet exchange; carrier shelves lift and lower hydraulically.
• Pallet pool control (PPC) is fully integrated with the OSP control.

Tower Automatic Pallet Changer
Store many pallets vertically with a multi-level automation. Featuring a mobile carrier system on the Z-axis and stationary shelves, the tower design provides ample pallet storage, easy operability, and long periods of unattended operations, including overnight shifts.

• 14-, 21-, and 28-pallet systems available for 2-, 3-, and 4-level towers, respectively.
• Table height of manual setup ST is standardized at 900 mm.
• New pallet pool control (PPC) is fully integrated with the OSP control and expands information display.
• Partner offerings available for certain part and operational requirements.

Automatic Work Changer (AWC)
Load and unload workpieces such as raw parts and fixtures with an automatic work changer. This CNC automation solution minimizes operator intervention and helps reduce spindle idle time while parts are staged.

• Valuable in high-mix, low-volume production environments where flexibility is critical.
• Optimal for small- and medium-sized parts.
• Compact structure and integration with the machine tool save shop floor space.
