The Haas ST Series high-performance turning centers were designed from the ground up to provide setup flexibility, extreme rigidity, and high thermal stability.
The ST-35Y is a medium footprint, big-bore lathe with a generous work envelope. The addition of Y-axis and live tooling allows milling, drilling, and tapping for increased machine capabilities. This machine offers the best performance for the money – the best value – in its class.
CHUCK SIZE | BAR CAPACITY | WORK ENVELOPE | AUTOMATION OPTIONS
We’ve completely redesigned our best-selling ST-35/Y turning centers to provide even more performance, features, and value than ever before. We’ve re-engineered everything – from the ground up – to create a more rigid machine, with superior cutting performance, and a host of productivity-enhancing options.

The compact footprint and redesigned sheetmetal of the new design yield a shorter distance between the door and center of the chuck for better ergonomics. The reduced reach to the chuck makes it easier for machine operators to manually load and unload parts. It also allows for faster automated (robot) part loading and unloading.
We’ve increased the angle of the wedge from 45 degrees to 55 degrees, which improves the overall chip flow inside the work envelope. The steeper inclination contributes to faster chip evacuation when using a chip conveyor (optional).
All Haas machines come standard with built-in WiFi for fast, wireless connectivity between the Haas control and a local area network. Use WiFi to easily share and transfer files wirelessly, and monitor your machine remotely via HaasConnect mobile machine monitoring. It is easily set up through the Haas control, and supports Netshare capabilities.
The Haas Auto Door is available on the redesigned machines, reducing operator fatigue, and simplifying automation. The Auto Door opens the machine doors automatically via an M-code, or can open them manually via a button on the control pendant. This reduces operator fatigue during repetitive machining operations, and allows for unattended operation when used with a robotic loader or our optional APL. The doors close automatically at Cycle Start, and can be controlled via settings to open at the end of a cycle, or at an Optional Stop.
NOTE: Availability my vary by region. Not available in Europe, except with robot and APL installations.
Our optional finishing sub-spindle will not only make you more productive, but also will provide new options for finishing the 2nd-op side of your parts.
This affordable A2-5 spindle is equipped with a 6.5" (165 mm) hydraulic chuck, and will fully synchronize with the main spindle to provide effortless “in-cycle” part handoff. This allows you to finish both sides of your part in a single setup – simply load your raw workpiece, and the next time you open the door, you’ll have a finished part. A built-in part ejector propels the finished part into the optional parts catcher for automated operation.
Note: Not compatible with the tailstock option. Not compatible with the Bolt-On turret.
Our two-stage automatic parts catcher moves completely out of the primary work envelope during machining, and quickly moves into place when commanded at the end of cycle. For parts with short cycle times, the arm can be left in the extended position, with only the tray rotating up to catch parts at the end of cycle.
The catch tray is easily adjusted for different part-off locations, and can be positioned to catch parts from either the main spindle or optional sub-spindle.
The new tailstock design allows setting the hydraulic pressure as low as 60 psi (4.1 bar) to minimize part deformation when machining thin parts. The Acme screw drive system provides better tailstock support during heavy roughing operations.

*Haas machines are designed to operate on 220 VAC power. An optional internal high-voltage transformer (380 - 480 VAC) is available for all models, except the Desktop Mill, CL-1, and CM-1.
Note: This optional high-voltage internal transformer is not field installable; it must be ordered with the machine.
