THE FOUNDATION FOR SUCCESS
Heavy-Duty, Cast-Iron Base and Components
Cast iron is more expensive to buy and machine, but it provides up to 10 times the damping capacity of steel.
That’s why Haas uses cast iron for all major components. Castings are FEA optimized to resist flex and damp
vibrations, and each casting is thoroughly inspected before and after machining to ensure it is free of flaws.
ST and DS series lathe castings feature heavy ribs that increase rigidity and improve thermal stability.
Compact, symmetrical headstock and tailstock castings further increase rigidity, ensuring high accuracy and
precise repeatability.
Cutting-Edge Design Tools Make it Possible
At Haas, we’ve learned that it’s less about the total mass of the machine’s structure
that gives the best results, and more about exactly where the mass is positioned.
By utilizing the most modern, cutting-edge design and analysis tools, our engineers
have put the mass exactly where it’s needed to provide a rock-solid base that
absorbs vibration and harmonics, while providing smooth surface finishes and great
repeatibility. For the Haas ST/DS series turning centers, all structural components
were optimized using finite element analysis (FEA) to produce the most rigid designs
and superior cutting.
Single Setup, Top-Down Machining
Haas ST/DS series base castings are machined in a single setup, using top-down
machining on Haas VS-3 vertical machining centers. Each casting’s spindle head
mount, Z-axis rails, and tailstock mounts are machined in a single setup, which
provides higher accuracies and smoother production. Our ability to precisely
machine all critical features of each casting eliminates alignment errors in final
assembly. High-accuracy, in-process inspection guarantees that every machined
casting meets our stringent quality standards.
