2017 PORTA Solutions MULTICENTER 3-Spindle CNC Production Machining Center
PORTA Solutions MULTICENTER 3SPINDLES CNC Production Machining Center – FANUC Control – Three Machining Units – 4-Station Rotary System – 2017
Alltech Industrial Services is offering a 2017 PORTA Solutions MULTICENTER 3SPINDLES CNC production machining center. This is a specialized multi-station production machining system designed for simultaneous and sequential machining operations in a compact manufacturing cell.
Manufactured by PORTA Solutions S.p.A. of Italy, this machine is identified as MULTICENTER, Model 3SPINDLES, Serial No. 101210, Work Order 1216.
Unlike a conventional single-spindle vertical or horizontal machining center, the PORTA MULTICENTER incorporates three independent horizontal FMU 110 XYZ machining units positioned around a four-station rotary indexing system. This configuration is intended for high-productivity manufacturing where multiple machining operations can be performed within a coordinated production cycle.

Three FMU 110 CNC Machining Units
The MULTICENTER is equipped with three FMU 110 XYZ horizontal machining units. Each unit incorporates its own spindle and automatic tool magazine.
Each FMU 110 unit features:
- 24-position automatic tool magazine
- Three 24-position magazines — 72 total tool positions across the three machining units
- Maximum spindle speed: 6,000 RPM
- Spindle interface: ISO 40 DIN 69871
- Maximum spindle motor power: 7.5 kW
- Quill diameter: 110 mm
- Maximum tool-feed stroke: 200 mm
- X-axis rapid traverse: 24 m/min
- Y-axis rapid traverse: 24 m/min
- Z-axis rapid traverse: 20 m/min
Machining Unit Operating Strokes
Each of the three machining units has the following documented operating movement:
X Axis: 125 mm negative / 125 mm positive — 250 mm total
Y Axis: 100 mm negative / 225 mm positive — 325 mm total
Z Axis: 200 mm
4-Station Rotary Machining System
At the center of the MULTICENTER is a rotary indexing system incorporating four satellite tables.
The manufacturer’s documentation specifies:
- 4 satellite tables
- 4 stations / 3 machining units
- Main rotating table: 360° rotation
- Main table indexing increment: 90°
- Satellite-table rotation: 360°
- Satellite-table positioning increment: 0.1°
- One operator loading/unloading station
- Manual loading/unloading in the documented configuration
- Machine designed to accommodate integration with robotic loading/unloading equipment
This arrangement allows a workpiece to move through multiple machining positions while the three machining units perform programmed operations.
FANUC CNC Control
The machine utilizes a FANUC CNC system combined with PORTA Solutions’ machine-management interface.
The PORTA interface provides machine control, diagnostics, semi-automatic functions and service functions while allowing access to the underlying FANUC interface.
The system supports automatic, semi-automatic and manual machine operation. In automatic operation, the machining units and spindles operate according to their programmed cycle.
Coolant & Chip Management
The manufacturer’s documentation describes an integrated swarf/chip and coolant-management system.
Documented coolant specifications include:
Machine/frame washing:
- Approx. 320 liters/minute
- Approx. 20 bar
- Rotary filtration with 50-micron metallic filter media
Through-spindle internal tool cooling:
- Approx. 60 liters/minute
- Approx. 20 or 40 bar, depending upon configuration
- 40-micron cartridge filtration
Electrical Requirements
Manufacturer documentation specifies the U.S. electrical configuration as:
Main Voltage: 480 VAC
Frequency: 60 Hz
Phase: 3-phase
Maximum Current Absorption: 125 amps
Maximum Installed Power: 80 kW
Auxiliary voltages are documented as 24 VDC / 110 VAC / 220 VAC.
Pneumatic & Hydraulic Systems
Compressed Air:
Working pressure: 6 bar / approximately 87 PSI
Average documented compressed-air consumption: approximately 1,330 liters/minute at 1 bar.
Hydraulic System:
- Tank capacity: 150 liters
- Hydraulic oil: HM 46
- Working pressure: 130 bar
- Hydraulic motor power: 4 kW
Machine Weight
The PORTA documentation lists approximately:
Machine body / electrical cabinet / hydraulic unit:
18,000 kg / approximately 39,683 lb
Coolant tank / swarf conveyor / rotary filters:
1,800 kg / approximately 3,968 lb
This represents approximately 19,800 kg / 43,651 lb for these documented major machine assemblies combined.
Because of the size and weight of this equipment, professional machinery rigging will be required.
Industrial Production Applications
The PORTA MULTICENTER configuration may be suitable for manufacturers requiring repetitive CNC machining of production components where multiple operations can be performed within an indexed manufacturing cycle.
Potential applications include automotive components, valve and fluid-control components, fittings, castings, forgings, industrial components and other medium- to high-volume precision-machining applications.
Actual suitability, tooling, fixturing and production capability will depend upon the buyer’s specific workpiece and process requirements.
Inspection & Sale Terms
Inspection is available by appointment.
The machine is offered as-is, where-is and is subject to prior sale.
Buyer is responsible for all rigging, loading, transportation and freight costs.
Specifications in this listing have been compiled from available manufacturer documentation and equipment information.
