Surface finish and cutting fluid combine to refract light into rainbows on a batch of ballscrew bearing housings after machining at Haas Automation.

This table for a Haas VM-3 Mold Making VMC is fresh off one of the large 10-pallet HMCs in the Haas machine shop. The top and bottom of the table are machined in a single setup to ensure parallelism between the table’s top and the mounting points for the guide trucks on the bottom. The VM table features T-slots in both the X and Y directions, plus precision dowel pin bores and a tapped hole pattern for fixturing versatility.

The typical Haas VMC has anywhere from 5 to 12 solenoids to activate various mechanisms throughout the machine, depending on options and machine configuration. Each solenoid has its associated airline and electrical connections. To simplify the assembly process, and make servicing machines in the field easier, Haas Automation has consolidated all of the solenoids into a single, easily accessible location, and color coded the airlines and electrical connections – so they are easily traced and accurately assembled.

This improvement is currently in place on all Haas small-frame VMCs, and soon will be implemented across all product lines – just another way Haas machines are constantly improving.

Haas Automation uses its own machines extensively to produce parts to build more Haas machines. In fact, nearly 75% of the metalcutting machines in the Haas machine shop –­ more than 200 –­ are Haas machines. This row of 9 EC-400PP Pallet Pool HMCs is busy pumping out servomotor mounts, ballscrew nut housings, and other precision components for the extensive Haas product line.

Fresh off the machine and ready for anodizing, these machined-from-billet vacuum chambers are a key component in Haas Automation’s patent-pending bearingless through-spindle coolant system.

Haas Automation currently produces approximately 20 DT-1 high-speed drill/tap centers each month, and every DT-1 is equipped with a 20-pocket side-mount tool changer. That's 400 tool pockets a month – just one example of the thousands of precision parts produced in-house at Haas.

These spindle heads for Haas ST-20 turning centers are ready for the next step in the assembly process, which entails mounting the drive motor and belts, as well as the C-axis drive assembly and brake, if specified.

All Haas ST and DS series turning centers feature compact, symmetrical spindle heads that increase rigidity and improve thermal stability. Cogged-style drive belts transfer power more efficiently, run cooler, and improve threading performance.

This is what’s underneath the platter of a Haas TR210 trunnion rotary table: a massive bearing, a large-bore spindle, precision ground surfaces, and a precisely engineered oil groove.

Many Haas turning centers are equipped with a hybrid turret that accepts both BOT and VDI toolholders for extreme versatility. Slots around the face of the turret accept standard “stick” turning tools; the bolt-on stations around the circumference provide rigid support for drills and boring bars; and the VDI stations accept axial and radial driven tools, and allow quick setup and changeover.

Air lines for the shift cylinders on Haas 40-taper gearboxes create an interesting pattern of copper and brass. The lines are preformed and then built into subassemblies, before being delivered to the production floor.

A row of mid-size Haas VMCs nears completion on the production line at Haas Automation’s SoCal manufacturing facility. Haas currently builds around 14 mid-size VMCs a day.

A row of spindle heads for Haas ST-20 lathes awaits assembly. Haas mounts the motors above the spindle so any heat generated moves up and away from the spindle to reduce thermal affects to the casting. The finned housings of the motors are left unpainted to increase heat transfer, so the motors run cooler. These two things combine to increase the thermal stability of the machines.

These double-arms for the Haas-designed and -built 40- and 50-taper side-mount tool changers are fresh out of one of the many FMS systems in the Haas machine shop. From here, they'll go out for black oxide, and then to the production floor, where they'll be assembled with the appropriate SMTC.

Light plays across the precision machined and ground surfaces of a Haas HRT310 rotary table as it goes through the assembly process at Haas Automation.

A Haas assembly technician checks the parallelism of the X-axis linear guides on a Haas VF-3 vertical machining center. These guideways are preloaded to provide zero clearance between the moving surfaces, which increases rigidity and stiffness in all directions, while providing higher accuracy and reliability. Linear guides consume less power, do not require adjustment, and are proven to outperform box ways for accuracy and speed.

The Haas VF-12, with 150" of X-axis travel, is the largest fully enclosed VMC currently built by Haas Automation. That much travel requires a very long saddle. In fact, the VF-12 saddle, shown here, measures a massive 238.5" long. Extensive ribbing and massive outriggers keep the saddle straight and true along its entire length.

This row of Haas HA5C collet indexers is ready for final assembly. The HA5C is the product that started it all for Haas Automation in 1983, and it is still very popular today.

Developed by Gene Haas to boost production in his own machine shop, the Haas 5C was the industry¹s first fully automatic programmable collet indexer. Today, Haas indexers and rotary tables help boost production in machine shops around the world.

These turret shafts for ST-20, ST-30, and ST-40 lathes are being machined in a new robotic cell comprising a pair of Haas SL-30 Big Bore lathes and a Motoman 6-axis robotic arm. The new cell produces more than 40 parts per day, unmanned.

But when you have big parts to turn, that’s a good thing. This is the A2-11 spindle nose of a Haas ST-40 lathe with Big Bore option. The ST-40 Big Bore provides a 7" spindle bore (without rotating union and workholding), and accepts an 18" chuck. In the background are a pair of A2-8 spindle noses for standard ST-40s.

A row of spindle shafts for Haas ST-20 lathes are prepared for final assembly into the spindle housings. All Haas spindles – for lathes and mills – are assembled in a temperature-controlled clean room to ensure the utmost quality and reliability.

The Haas 12-station hybrid tool turret for ST lathes provides 6 bolt-on stations for super-rigid mounting of turning tools and boring bars, and 6 stations for quick-change VDI40 tools, including driven tools. Haas turrets are finish-machined as a complete unit­ – assembled with the coupling, gearbox, and drive system ­– on Haas EC-630 HMCs. Keying off the turret's centerline, all critical features of each station are machined using single-axis moves, and then the turret is indexed to the next station. This ensures the absolute concentricity of each station with the turret’s true center.

To operate safely and accurately, a CNC machine must "know" where all of its components are at any given time. Proximity sensors, such as these, located throughout the machine, provide much of this location information. Haas uses a common sensor across the product line to reduce costs and simplify service.

Back in 1983, Gene Haas developed the industry’s first fully programmable collet indexer as a means to increase production in his own machine shop. That product started it all for Haas Automation.

Today, Haas produces more than 35 models of single- and dual-axis rotary tables and indexers – including the massive HRT600 shown here – and ships roughly 300 units a month to machine shops around the world.
