4 & 5-axis horizontal machining centers, 500 mm pallets to six-metre parts.
Mandelli started in Piacenza, Italy in 1932 as a precision machining shop, built its first machining center in the 1960s and has built them ever since. Four and five axis, milling and multitasking, on pallets from 500 mm on the HS-50 and 630 mm on the HS-63 to 800 mm and larger on the SPARK machines — up to the SP 4000 carrying twenty tonnes and the six-metre RUMBLE profiler.
This is the tier above a trunnion VMC: pallet-pool production, titanium structural work, and cell automation measured in machines rather than in robots. Aerospace engine cases, blisks and landing gear; power generation impellers and turbine components; large transmissions and molds.
For most Northeast shops the place to start is the SPARK 2 HS: the compact HS-50 and HS-63, 4- or 5-axis, milling and turning in one machine, with pallet automation built in. See the HS series ↓

The HS is the SPARK architecture scaled down for the size of part most Northeast shops actually run. It is a multitasking machine — turning and milling in one setup — built for fast machining: 75 m/min rapids, 7 m/s² acceleration, and quick tool and pallet changes. Mandelli’s stated goal for it is high productivity and a shorter return on investment.
It is modular, on a one-piece base, which Mandelli say eases transport and installation. Tooling comes from multilevel racks or an anthropomorphic robot with an arena magazine, and the automatic pallet changer runs on one or two levels with a centring station — so the multi-pallet version can run unattended, around the clock. Three thermal circuits monitor and manage thermal change to hold accuracy.

Why horizontal
The chips fall out, and the pallet keeps working
On a vertical machining center chips collect in the pocket and the operator stands at the machine. A horizontal spindle lets swarf fall clear of the cut, which matters enormously in deep cavities and in material where re-cutting chips destroys tool life. It also puts the workpiece on a pallet — and a pallet can be loaded while the machine is still cutting the last one.
That is the real argument. A horizontal machining center is a production machine that expects to keep running. Mandelli have been building them since the 1960s and describe themselves as specialists in machining center automation, which is the same thing said a different way.

Hard material
SPARK Ti: designed to leave semi-finishing out
The Ti variant is built for titanium and superalloys. A double-drive tilting head generating 12,000 Nm of continuous torque, backlash-free kinematics, damping technologies that Mandelli state reduce vibrations by 75%, and coolant at 100 bar in milling and 350 bar in turning.
Mandelli's claim for it is specific and worth quoting: it is the 5-axis machining center that leaves semi-finishing operations out. On titanium structural parts that is not a marginal saving — it removes an entire pass from the process.

Scale
From a 500 mm pallet to a six-metre profiler
The SPARK line starts with the SPARK 2 HS — a 500 mm pallet on the HS-50, 630 mm on the HS-63 — moves to 800 mm pallets on the SP 1200 and larger from there, and runs up to the SP 4000, with 4,000 mm of X travel, carrying up to 20 tonnes in milling. Beyond that the RUMBLE profiler reaches 6000 mm of X, built on a modular concept where the X stroke can be any multiple of two metres.
RUMBLE was the platform Mandelli supplied in 2008 for machining a six-metre titanium workpiece for the Boeing 787. Positioning accuracy across the range is 4–5 μm with 3–4 μm repeatability, and 4 arcsec on the rotary axis.

Automation
Pallet pools, tool rooms and a robot on an aerial rail
This is cell-level automation rather than a robot beside a machine. Pallet handling runs from a twin automatic changer, through a transpallet system with up to eight buffer stations, to in-line or multilevel systems of 5 to 100 pallets with loading, unloading and centring stations — all integrable with the plant ERP.
Tooling is handled the same way. A shared tool room holds over 500 cutting tools serving two or more machines, with an anthropomorphic robot on an aerial rail moving tools in batches of five between the room and each machine's changer. Mandelli's figure is that one operator can manage the tool set across five machines. The machine magazines themselves hold up to 500 tools on multilevel trays, with laser tool control and ID, air-blast and wiper cleaning of the tool cone before every pick-up, and a servo bracket for fast changes even with heavy tools.

The software
iPum@ — where the AI actually sits
Four native systems. iPum@Control is the 22-inch interface. iPum@Scada optimizes pallet flow from real-time data. iPum@Predict processes machine data to catch conditions that would lead to a fault before they do — Mandelli say up to 48 hours in advance.
The interesting one is iPum@Smartcut, which monitors the cutting process and actively damps vibration to stabilize the cut. On the SP 2100 Mandelli describe it as avoiding chatter on the component surface by exploiting the machine's own structural rigidity. That is a machine intervening in its own process while it runs — the same principle as the Shibaura run-out retry, applied to chatter instead of tool condition.

The heads are electro-welded steel or spheroidal cast iron, thermally stabilized, on dynamically balanced ceramic bearings with a pneumatic system that varies the bearing preload with spindle speed. A dedicated chiller controls spindle temperature, and thermal compensation of spindle growth is built into the NC. A sensor network adjusts or stops the spindle at preset alarm thresholds, detects vibration to prevent chatter automatically, and a tool-presence sensor guards against crashes.

Common questions
Horizontals, answered plainly.
What is the difference between a horizontal and a vertical machining center?
Spindle orientation, and everything that follows from it. A horizontal spindle lets chips fall clear of the cut rather than collecting in the pocket, which matters in deep cavities and in materials where re-cutting swarf destroys tool life. Horizontals are also built around pallets, so the next part is loaded while the current one is still being cut. Verticals are cheaper and simpler and suit lower volumes and flatter parts; horizontals are production machines.
What size parts can these machines take?
Pallets start at 500 mm on the HS-50 and 630 mm on the HS-63, move to 800 mm on the SP 1200 and grow from there, up to the SP 4000 with 4,000 mm of X travel, which carries up to 20 tonnes in milling. Beyond that the RUMBLE profiler reaches 6000 mm of X travel and is built on a modular concept where the X stroke can be any multiple of two metres.
Are these suitable for titanium and superalloys?
That is what the SPARK Ti was built for. A double-drive tilting head producing 12,000 Nm of continuous torque, backlash-free kinematics, damping that Mandelli state reduces vibration by 75 percent, and coolant at 100 bar in milling and 350 bar in turning. Mandelli's stated aim for it is to eliminate semi-finishing operations entirely.
Can they turn as well as mill?
Yes. The multitasking versions combine turning and milling in one machine, with the table fixed to the base and a direct drive motor sunk into the structure generating up to 7,600 Nm of continuous torque. Spindles are locked with Hirth rings during turning to provide stiffness and protect the bearings.
What automation is available?
Pallet handling from a twin automatic changer through to in-line or multilevel systems of 5 to 100 pallets with loading, unloading and centring stations, all integrable with plant ERP. Tooling is served by a shared tool room holding over 500 tools with an anthropomorphic robot on an aerial rail moving tools between the room and each machine. Mandelli's figure is one operator managing the tool set across five machines.
What accuracy do they hold?
Positioning accuracy of 4 micrometres with 3 micrometres repeatability on the smaller models, 5 and 4 micrometres on the larger, measured to ISO 230/2. Rotary axis accuracy is 4 arcsec with 3 arcsec repeatability. Measurement is by high-resolution pressurized optical scales on the linear axes and encoders on the rotary table.
One relationship
Machines from LOMA. Everything they run on from NSIT.
A horizontal lives on pallet changes and unattended hours — which makes repeatable workholding and a crib that never runs dry the difference between a spindle that cuts and one that waits.
Zero-point and form-fit workholding
HWR SOLIDPoint and SOLIDBolt zero-point systems, SOLIDGrip centering vises and SOLIDStamp form-fit clamping — pallets that repeat, and blanks prepped off the machine instead of on it.
Our sister company North Shore Industrial Tool handles what the machine runs on — cutting tools, toolholding, workholding, metrology and a managed inventory program. Same people, same phone number, so the machine arrives with the tooling package already sorted.
