Coordinated five-axis CNC interpolation guided by high-precision optical linear scales.

Non-rotating bar transfer machines Trans-Bar

Buffoli TRANS-BAR and TRANS-BAR-TURN multi-spindle bar machining machinery. Bar stock or coiled wire is fed into the clamping stations without workpiece rotation, while orbiting multi-axis cutting tools shape the metal, eliminating centrifugal vibrations and delivering strict axial alignment.

Machining of stationary round, hexagonal, and custom profile steel and non-ferrous bars.
Elimination of centrifugal workpiece wobble and vibration during high-speed tooling cuts.
Built-in precision bar cutoff saws, automatic chamfering, and internal cavity boring units.
Automated high-capacity bar feed magazines and synchronized parts unloading carousels.

Spindle assemblies, turret heads, and tooling

High-precision motorized spindles, boring cartridges, heavy milling heads, and tooling for Buffoli machinery. Precision spindle units feature hybrid ceramic bearings, multi-stage labyrinth seals, and positive air purge pressure preventing ingress of cutting fluids and fine particulate chips.

Direct-drive milling and drilling electrospindles delivering rotational speeds up to 24,000 RPM.
Multi-station indexing tool turrets incorporating rigid HSK-C and HSK-A clamping tapers.
Precision collet chucks, quick-change toolholders, and rigid modular boring adapter bars.
Hydraulic and pneumatic clamping chuck fixtures securely centering parts in table nests.

Indexing table mechanisms, Hirth couplings, and hydraulics

Critical kinematic drive elements, rotary table indexing parts, and hydraulic controls from Buffoli Meccanismi. Precision Hirth tooth crowns, ground ball screws, linear guides, directional valves, and hydraulic power packs maintain smooth motion and rigid clamping throughout heavy production cycles.

Hardened alloy steel Hirth coupling crowns ensuring exact angular indexing and locking.
Ground preloaded recirculating ball screw assemblies for dynamic multi-axis feed motions.
Heavy-duty linear roller guideway rails equipped with multi-lip protective wiper seals.

Italian precision machine tool engineering and Buffoli industrial heritage

Italian machine tool manufacturing group Buffoli Industries traces its engineering heritage back to 1952, when the initial Buffoli engineering office was established. In 1958, Dr. Mario Buffoli founded Buffoli Transfer S.p.A.

in Brescia, the renowned industrial heartland of northern Italian precision manufacturing. Over seven decades of sustained technical innovation, the enterprise has grown into an international leader in rotary transfer machinery and automated manufacturing systems.

The flagship production enterprise Buffoli Transfer S.p.A., together with InterMach Service, Buffoli Meccanismi tooling division, and Advanced Robotics automation arm, form a unified manufacturing cluster.

This integrated model combines mechanical engineering, proprietary numerical control software development, and precision machinery assembly under strict European industrial manufacturing quality standards.

Kinematics and layout of CNC rotary transfer machinery (RTM)

Buffoli rotary transfer machines across TR, TG, Trans-N-Center, and Multi-Way model families are engineered for high-volume manufacturing of complex parts from forged, cast, or pre-formed metal blanks.

The machine design features a rigid thermosymmetric bed structure paired with a heavy-duty rotary indexing table locked by precision Hirth tooth crowns that resist heavy cutting forces without angular deflection.

Configurable from 4 to 20 machining stations with horizontal or vertical spindle heads, each unit operates concurrently.

Simultaneous execution of multi-axis drilling, deep-hole boring, contour milling, threading, and recessing reduces production cycle times to mere seconds per fully finished metal component.

Stationary bar machining technology on Trans-Bar production systems

The patented Buffoli TRANS-BAR machining concept delivers an efficient technological alternative to conventional Swiss-type lathes and multi-spindle automatic turning machines.

Raw bar material or coiled wire feeds linearly into stationary hydraulic clamping stations without bar stock rotation, while high-speed revolving planetary tool blocks execute complex contour cutting.

This kinematic layout completely eliminates the centrifugal vibrations, whip, and acoustic noise typical of rapid bar stock rotation.

As a result, finished mechanical workpieces achieve exceptional dimensional repeatability, strict bore concentricity, and fine surface finishes throughout non-stop three-shift manufacturing schedules.

Multi-spindle flexible mill-turn centers of the Omni platform

Modular machining platforms such as Omni-Turn and Omni-Flex merge the high productivity of transfer machinery with the processing adaptability of five-axis machining centers.

These systems incorporate rapid-indexing tool turrets with HSK toolholders, high-torque liquid-cooled electrospindles, and digital axis servo drives.

The machinery is widely utilized in producing automotive components, industrial gas valves, high-pressure hydraulic manifolds, and precision fittings.

Quick numerical control changeover protocols allow production facilities to shift rapidly between product variations in small and medium batch quantities.

Proprietary Buffoli CNC electronics and Industry 4.0 automation

Dedicated electronics unit Electro Engineering designs proprietary Buffoli CNC control systems engineered specifically for multi-channel synchronization across dozens of independent axes.

The graphic operator human-machine interface delivers intuitive station monitoring, dynamic tool wear tracking, and automated thermal drift compensation routines.

The digital control architecture natively interfaces with Advanced Robotics handling arms, automatic billet loaders, and standard enterprise factory networks. Integrated digital twin simulations and telemetry tools enable predictive equipment maintenance while cutting unplanned line downtime.

Spare parts procurement and engineering specification by machine records

When ordering replacement assemblies, spindle cartridges, or control boards for Buffoli machinery, precise technical identification is required.

Engineering specialists cross-reference item numbers against machine serial records, factory rating plates, assembly schematics, and electrical wiring diagrams.

Engineers verify mounting dimensions, bearing load capacities, lubrication specifications, and servo interface signals. Direct collaboration with European distribution centers and approved component suppliers ensures delivered spare parts comply fully with Buffoli factory maintenance standards.
