NOTE: All specifications listed are for the standard machine configuration. Optional equipment may change the machine’s specifications.

*Haas machines are designed to operate on 220 VAC (200-240 VAC) power. An optional internal high-voltage transformer (380 - 480 VAC) is available for all models, except the Desktop Machines, CL-1, CM-1, and SR Series routers. This optional high-voltage internal transformer is not field installable; it must be ordered with the machine.

Haas machines destined for Europe and the UK are configured with an internal high-voltage non-isolated transformer to operate on 400 VAC, except the Desktop Machines, CL-1, CM-1, and SR Series routers. 

**Optional tool changers may have a different max tool size than the standard tool changer. Extra-large tools may require two adjacent pockets empty between tools. Click here for toolholder specifications.

ATTENTION! Optional high-performance spindles may have a higher power requirement than the standard spindle. However, if the spindle horsepower (kW) does not change, the power requirement remains the same. Verify the power requirement before running power for your machine.

† Air consumption on 40-taper DC Series machines may be higher, when Through-Tool Air Blast (TAB) is activated.

 

* Not all options are compatible with each other. Some options may require the purchase of additional options, or may include additional options at no charge. Please use our Build-&-Price tool to determine option compatibility, and configure your machine.

Improved Part Loading Ergonomics

The more 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.

Increased Wedge Angle

We’ve increased the angle of the wedge from 45 degrees to 55 degrees, which improves the overall chip flow inside the work envelope, and reduces the machine’s footprint by 11%.

WiFi Connectivity Standard

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. 

  • No cables required
  • Ideal for large shops with many machines
  • Ideal for shops where the machine is far from the network router
  • Easily transfer and share files 

Automatic Door (Optional)

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.

  • Improves machine ergonomics
  • Reduces operator fatigue during repetitive machining operations
  • Operates automatically via M-code, or manually via a button on the control pendant
  • Allows for unattended operation when used in conjunction with a robotic loader or APL
  • Closes automatically at Cycle Start, and can open automatically at cycle end or an Optional Stop

Sub-Spindle (optional)

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 5.3" (135 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.  
 

  • 6000 rpm
  • A2-5 spindle nose
  • 5.3" (135 mm) hydraulic chuck 
  • 1.3" (33 mm) spindle bore (non-through)
  • Allows fully synchronized part pass-off (up to 4800 rpm)
  • Built-in part ejector
  • Includes CNC Control Cabinet Cooler

 

Two-Stage Parts Catcher (optional)

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.

Automatic Parts Loader (optional)

The Haas Automatic Parts Loader is a simple and affordable way to automate part production and boost productivity on Haas turning centers. It is designed and built exclusively for use on Haas turning centers, and connects directly to the Haas control. 

  • All-inclusive design, with plug-and-play capabilities to Haas ST-10 through ST-25 turning centers, including Y-axis models
  • Interfaces directly with the Haas control
  • Accommodates parts up to Ø5.8" x 5" x 10 lb (Ø147 x 127 mm x 4.5 kg)
  • Includes light curtain for safe operation
  • Made in the USA

New Tailstock Design (optional)

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.
