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%.

Automatic Door Standard

The Haas Auto Door comes standard 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.

  • 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

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 

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.

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.

LATHE Drilling: EVERYTHING YOU NEED TO KNOW
Mark shows you everything you need to know to drill on a Haas lathe. Whether you have a standard 2-axis lathe, a dual-spindle lathe, or even a live-tool lathe, Mark simplifies the process, and explains all the G and M codes you’ll ever need.
CUT CYCLE TIMES AND POSITION YOUR TURRET USING G53
Mark demonstrates how using a G53 command instead of G28 not only saves valuable cycle time, but also reduces the risk of crashing your machine. Mark walks you through both G-codes, and explains how and when to use each one.
THE HAAS BMT65 TURRET
Why move your turned parts to a mill for secondary operations when you can machine them complete on a Haas lathe with the BMT65 turret and live tooling? The BMT65 system provides increased cutting performance, longer tool life, and better tool clearance.
Setting Up Live Tools
Properly setting up live tools on a turning center can be tricky. Mark guides you through the process with a step-by-step tutorial that will answer all your questions.
