a 5-axis machining centre with auto pallet-cart changer system
The Eumach HSM-550U-5X Machining Centre Features
Outstanding precision, productivity and reliability make Eumach 5 axis machining centres the ideal solution for high speed 5 axis machining applications such as aluminum, titanium and special alloys. The HSM series has rapidly been increasing in demand in the aerospace, medical optical, automotive and other industries.
For more than the last 12 years Eumach has been developing groundbreaking solutions to the challenges of this growing market - from the smallest 255mm diameter table up to 1650mm diameter - or by using 2 axis milling heads on large size double column machines.
The following benefits from these solutions are significant:
Fewer set-ups: maximum number of tasks achieved in a single operation with less misalignment
Less handling: minimal risk of collision damage
High flexibility: machining centres with 24, 32 or 40 tool magazine with automatic tool changer
Reduced cycle time: using high speed cutting function from the latest advanced CNC controls
Reduced lead times: less operations
Common platform: suitable for different parts
Low cost of ownership: maximum cost-benefit ratio through entire lifecycle

The Benefits of Automatic Multi-Pallet Changing
lights-out manufacturing with multiple pallets automatically being changed using multiple pallet carts without an operator
high spindle up-time with parts being loaded/offloaded on one pallet while machining a part on another pallet at the same time
The Midaco Automatic Pallet-Cart Changer System includes: 1 – APCC15 Shuttle and Automatic Door (retrofit to the machining centre) 1 – Cast Iron Receiver Base, 150 lb. capacity (with weight evenly distributed) 2 – 15” (381 mm) dia. x 1.25” (31.75 mm) thick Cast Aluminum Pallets 1 – Pallet Cart with interlocking T-pins (holds 2 pallets) 1 - CE Light Curtain package with shuttle guarding via a light emitter, mirrors and sensors
the receiver with dimensional drawing:
The pallet receiver is mechanical and actuated by the pallet transfer arm so no air or hydraulics are required to operate this pallet clamping system.
Work NON-STOP on 5-Axis Machining Centres The Automatic Pallet-Cart Changer allows for uninterrupted pallet transfer with MIDACO’s train cart* system (patent pending). Each cart holds two (2) pallets and connects to additional carts allowing for continuous and uninterrupted part transfer in and out of the machine tool. The operator can load a train of carts* to run while they attend to other tasks or go "lights-out".
Easily load and unload pallets onto carts without obstruction.
Interlocked pallet carts are mobilized through the shuttle system on casters allowing the shuttle arm to continuously feed pallets into the 5-Axis machining center.
Once a cart is pushed through the other side, the operator can easily load new pallets and change parts while the spindle is cutting.
A completed pallet cart can be removed by unlocking the T-pins and rolled to a different location or to the opposite end of the train to keep production going.
Depending on programming, after the full “pallet cart train” passes through the shuttle, the process repeats sending carts back in the opposite direction.
