 The Puma 3100 horizontal turning center eliminates thermal deformation. Its thermal isolation system is designed to prevent machine-generated heat from reaching the bed or headstock. Strategically placed covers deflect heat away from sensitive areas, while fans exhaust heat from the machine. In addition, a 1.2-hp multistage centrifugal pump delivers coolant at 65 psi, which meets the criteria of most insert manufacturers. It is, also, sufficient to flush chips from drilled holes, reducing the need for peck drilling cycles. Coolant is stored in tanks ranging from 60 to 126 gallons depending on the model selected.

 
A Presci-Flex tooling system uses a single base holder configured to accept collets, end mill holders, expanding collet chucks, shrink fit tooling, and Capto and KM system tooling. A conical and flat-face planar interface is designed to ensure superior accuracy and rigidity.
 
The turning center is suitable for parts as large as 16.5” diameter × 29.9” long (a model with an elongated bed extends part length to 50.4”), and accepts barstock to 4” diameter. A 30-hp motor drives the spindle at speeds as high as 2,800 rpm and generates a maximum spindle torque of 828 foot-pounds. 
 
A 12-staton turret selects BMT65 tools bi-directionally in 0.15 second. The turret is non-lifting to eliminate the possibility of contamination reaching the coupling. A 9” curvic coupling with 11,900 lbs of hydraulic clamping force is designed to provide high rigidity for heavy stock removal, fine surface finishes, long boring bar overhang ratios and extended tool life. Rotating tools are powered by a 7.5-hp motor, generating 34.7 foot-pounds of low-end torque and speeds as high as 5,000 rpm. A tool setter reduces setup time by minimizing the need for manual skim cuts. Offsets are calculated and automatically entered into the program.
 
A one-piece, fine-grain Meehanite casting inhibits thermal deformation and twisting, and dampens shock and vibration. The bed is a 30-degree slant bed design to maintain minimal and constant distance between the tool tip and bedways. Each guideway is induction hardened, precision ground, bonded with a fluroplastic resin, and hand scraped for further vibration dampening and to provide an appropriate flow of lubricant along the guideway surface, the company says.
 
Additional standard features include a way lube separation system, chip guarding, an 87-degree swiveling operator’s panel, Fanuc embedded Ethernet function, and a tool monitoring system that monitors spindle and axis load while the axis is feeding. Both overload and underload conditions are monitored to assist in optimizing operating conditions. Also available is a programmable tailstock with a built-in live center for Y-axis models.
