20+1 Pallet Pool, UMC-500/SS

   
High-volume production, unattended operation
  • 20+1 Stations
  • 8" x 8" Pallet Size

TECHNICAL DOCUMENTS

Our 20+1 pallet pool for the UMC-500/SS is perfect for high-volume production runs, or high-mix/low-volume machining. The pallets can be scheduled individually according to priority and sequencing requirements, allowing high-priority parts to be machined first or staged more often. Completed pallets are returned automatically to the holding location, or can be sequenced to a protected operator station for immediate unloading and re-loading.

NOTE: Requires optional 50+1 or 70+1 side-mount tool changer. A hopper-style chip bin is required to clear the 95-gallon (360 L) coolant tank. The Pallet Pool must be anchored for proper operation. Must be ordered with the machine. 

  • Work Envelope: 8" dia. x 16.5" tall (203 x 420 mm)
  • 20+1 pallets (20 storage locations + 1 machining station)
  • 200 lb (90 kg) max payload per pallet (workpiece + workholding)
  • Fully integrated solution for lights-out production
  • Easy-to-use scheduling interface in the Haas control
  • Dedicated load/unload station
  • Must be ordered with the machine

UMC-500(SS) Pallet Pool Overview

The 20-Station Pallet Pool option for the Haas UMC-500 and UMC-500SS Universal Machining Centers is designed for high-volume production and unattended operation. This manufacturing solution also excels at high-mix/low-volume part runs, because the user can assign a specific part program for each pallet. Each time that pallet is moved into the machining area, the control will automatically call the assigned part program.

UMC-500(SS) Pallet Schedule Table

Pallet Schedule Table Interface

The simplified Pallet Schedule Table (PST) controls pallet scheduling functions from a dedicated screen. Pallets can be scheduled individually according to priority and sequencing requirements.

  • Each pallet is identified with a number (1 through 21), and each storage location within the Pallet Pool and machine is identified with a letter (A through U). The storage locations do not change, but the pallet ID numbers move, so you can quickly see where any pallet is at any time. Translucent numbers indicate a pallet’s destination when the pallet pool is in motion.
  • The LOAD ORDER column indicates the scheduled priority of each pallet. Schedule pallets by pressing the Pallet Schedule button at the load station on the pallet pool, by pressing the F2 key while the desired pallet is highlighted on the PST, or by simply entering a number in the LOAD ORDER column for that pallet.
  • Highlight the PROGRAM NAME column for a pallet, and press ENTER to navigate to the program list and select which program to run each time that pallet is loaded into the machine.
  • One-Touch function keys from the PST simplify common tasks when operating the machine.
    • Press ALTER to load the highlighted pallet into the machine and activate its designated program.
    • Press INSERT to run the active program. This button starts the cycle in “Pallet Mode.” Pallet Mode will interpret an M199 code as: “load the next-scheduled pallet, and run its assigned program” (see below).
    • Press F2 to schedule the highlighted pallet.
    • Press F3 to send the pallet on the Load Station (Shelf A) to an empty station in the pallet pool.
    • Press F4 to bring the highlighted pallet to the Load Station (Shelf A).

We developed a new M-code for use with Automatic Pallet Changers. M199 is typically used at the end of a program. When the program is started by pressing [CYCLE START] in Memory mode, the M199 acts exactly like an M30 (Program End and Reset). But if the program is started by pressing [INSERT] while the Pallet Schedule Table is displayed (PALLET MODE), the M199 will command a pallet change to load the next scheduled pallet, and then run the program associated with that pallet. This allows the user to start machining on any pallet, even a mid-program start, and continue uninterrupted machining as long as pallets are scheduled.

UMC-500(SS) Pallet Details

When the 20-Station Pallet Pool option is ordered with the machine, the customer gets a total of 21 pallets. Each pallet is 1" (25.4 mm) thick, and measures 7.9" x 7.9" (200 x  200 mm). Pallets are made of mild steel, with a precision machined top surface that can be drilled and tapped to accept custom tooling or standard vises. The work envelope with these pallets is 8" (203 mm) Diameter x 16.5" (419 mm).

  • Mild steel with blank top surface
  • Drill and tap as needed for aftermarket workholding 
  • Easily accomodates custom fixtures
  • Extra pallets available
  • 7.9" x 7.9" (200 x 200 mm) pallet size
  • 8" (203 mm) diameter x 16.5" (419 mm) tall work envelope

Requires 50+1 or 70+1 Side-Mount Tool Changer

The 20-Station Pallet Pool option requires the addition of a Haas-designed and -built 50+1 or 70+1 side-mount tool changer, to provide additional tool pockets for backup tooling and running multiple jobs. These tool changers feature a double-arm gripper that swaps tools quickly to minimize non-cutting time.

The tool changers feature a servo-driven carousel that allows direct positioning to any tool in the carousel. No more indexing one pocket at a time. Faster positioning reduces cycle times during short machining operations, or when the carousel is not pre-staged for the next tool. With adjacent pockets empty, the tool changers will accept oversize tooling, and there’s a built-in automatic recovery process, should a tool change be interrupted for any reason.

  • Direct-positioning carousel for super-fast tool staging
  • Fast tool changes shorten cycle times on every tool change
  • Pocket Tool Table in the control allows complete control over the tool changer
  • Identify tools as LARGE to leave adjacent pockets empty
  • Identify tools as HEAVY to slow tool changer motion

Includes CNC Control Cabinet Cooler

The Haas CNC Control Cabinet Cooler is a fully integrated air conditioning unit for your Haas control electronics. It eliminates downtime due to heat, by reducing the internal temperature of the control cabinet by 20°F (11°C), boosting reliability and increasing the life of the components. This factory-installed option is powered directly from the control, and mounts directly to the control cabinet door. The A/C unit ships separately, and is installed by your HFO. 

  • Reduces the internal temperature of the control cabinet 
  • Increases duty cycles in demanding applications by maintaining cooler electronics 
  • Boosts reliability and extends the life of electronic components
  • Powered directly from the Haas control
