These spindle shafts for Haas HRT310 rotary tables are halfway through the machining process, and ready for op 2. The shafts are machined complete – turned, bored, drilled, and tapped – in two setups on Haas ST-40 turning centers with live tooling. The ODs are then precision ground for the worm gear and bearings. The worm gear is hobbed after it is attached to the spindle to ensure the utmost concentricity between the large diameter bearings and the worm gear.
These massive BOT turret assemblies are for the new Haas ST-55 large-through-bore turning centers, introduced at the end of 2014. The 12-station bolt-on style tool turrets accept 7.25" (184 mm) split boring bar holders, as well as standard BOT toolholders.
All Haas turrets are finish machined as a complete unit – assembled with the coupling, gearbox, and drive system – to ensure the absolute concentricity of each station with the turret’s true center.

These transfer gears for the Haas-built 40-taper gearbox are on their way to becoming some of the finest AGMA Class 13 gears in the industry. The gear blanks are saw-cut in-house, and then turned in two ops on Haas SL-20APL turning centers with automatic parts loaders. The gears are then hobbed and chamfered, before being sent out for heat treating to 54-58 RC. After heat-treat, the bores are honed, and then the teeth are finish ground and deburred.
An operator loads drive shafts for the Haas-built 40-taper gearbox into a fixture on one of the four pallets of a Haas VF-3APCQ machining center in the Haas machine shop. The shafts are first saw cut to length, and then all ODs are turned on a Haas SL-30 lathe, leaving stock for subsequent heat treat and grinding operations. They then go into the VF-3APCQ to drill drive holes for the grind operation. After the mill, the shafts go to a robotic cell for grinding, and then the gears are hobbed and chamfered, before the shafts go to heat treat. After heat treat, the drive shafts go to another robotic cell to finish grind the bearing surfaces, and then the gears are precision ground to complete the cycle.
These tool changer carousel plates are fresh off one of the many FMS systems in the Haas machine shop. The plates are for the 20-pocket carousel tool changer that is standard on many Haas small and medium VMCs.

Weight is objective. Or is it subjective? I'm not a weight weenie. Put your money where your mouth is. Uber light weight parts are prone to an early retirement. Why spend so much money over and over when you only shed a few ounces versus my sled which will survive the apocalypse.
I'm also not judgemental. To each their own. Opinions are like leaves or needles, every tree has at least one at some point.

The Haas assembly floor now uses electronic work instructions running in custom applications on Apple iPads to ensure that every product is built to exacting standards, and every process is completely documented and traceable.
Haas began implementing electronic work instructions on the assembly floor in January 2012, as a first step toward becoming a “paperless” factory. Since then, the company has reduced its paper consumption from 13.5 million pages per year to 3.6 million pages per year – a decrease of nearly 75%. The Assembly Department alone, one of the most paper intensive departments, has reduced monthly paper consumption from 645,250 pages to 40,000 pages – a decrease of nearly 94%! Currently, there are more than 400 iPads deployed throughout the Haas factory, with more planned as other departments come online.
These spindle shafts for HRT450 rotary tables are fresh off one of the precision OD grinders in the Haas Automation machine shop. Next, a large-diameter aluminum-bronze gear blank will be assembled to each shaft, and then each spindle assembly will be trammed-in on a CNC gear hobber to a maximum 2-micron runout before the worm gear is cut. Cutting the worm gear after it’s assembled to the spindle shaft ensures perfect concentricity of the gear pitch diameter to the bearing journals and the spindle axis.
Looking like a squadron of flying saucers, these A2-5 spindle shafts will soon be assembled with bearings and spacers to create complete spindles for Haas ST-10 turning centers. The shafts are turned from bar stock on a Haas SL-40L Long Bed turning center – equipped with live tooling and C axis – in one of the many robotic cells at the Haas Automation factory in California.
These 30-taper spindle shafts for the Haas DT-1 Drill/Tap Center are fresh off the OD grinder and ready for the next operation. The tapers will be finish ground next, and then the shafts will move to a lathe robotic cell to hard turn the bearing threads and mill the drive slots. Once machining is complete, the shafts will be fitted with high-precision ceramic bearings and built into high-performance 15,000-rpm spindles.
Haas EC-1600 HMCs are available with an optional 4th-axis rotary system integrated into the T-slot table.

Haas Automation is continually improving its products and processes in order to provide more value to its customers. Often, those improvements come directly from the shop floor.
These castings for the tool-release piston on Haas 40-taper inline direct-drive spindles are machined in a single setup on one of the many FMS installations at Haas.
But that wasn’t always the case. The component used to be three separate pieces, requiring machining on several machines. An astute Haas machinist, however, realized that turning the assembly into a single casting would not only eliminate parts, but also simplify the assembly process. The part was subsequently re-engineered – improving a process, and adding more value.
First-article castings await inspection at Haas Automation. All first-article castings are thoroughly inspected and measured to ensure they comply with design specifications.
The inspection process used to involve rulers, tape measures, height gauges, and lots of time. Today, the castings are measured quickly using a laser scanner that feeds the data directly into the computer for comparison to the solid models. The castings are painted with low-reflectance paint, and reflective dots are placed onto all casting surfaces. The scanner recognizes the dots as data points, which are then used to create a computer model of the casting.
Secured safely behind wire mesh, Haas 40-taper spindle housings are machined without human intervention in one of the many robotic cells in the Haas Automation machine shop. The cell consists of two SL-40 lathes and a 5-axis VF-5 VMC equipped with a trunnion rotary table. A 6-axis Motoman robotic arm keeps the parts flowing from machine to machine.
A Haas machinist checks the bore of a brake disk for a Haas HRT310 rotary table after machining in one of the many robotic cells in the Haas machine shop. The disks are machined in a pair of Haas SL-40 turning centers that are tended by a 6-axis Motoman robot; it is one of the first robotic cells installed at Haas.
A Haas UMC-750 undergoes a ballbar test during final assembly at the Haas manufacturing facility in Oxnard, CA. Haas uses a state-of-the-art ballbar test to check the linear positioning and geometry of every machine. The ultra-precise ballbar tracks movement as the machine is put through a series of circular moves to certify synchronous movement and verify machine geometry. This generates a chart illustrating machine condition and performance data. Any deviations in geometry or position show up as distorted circles that are very easy to spot. A copy of this chart ships with each Haas machine as assurance that it is accurate and properly aligned.
When Haas Automation introduced the VF-1 at IMTS in 1988, it achieved an industry milestone: the first American-built vertical machining center (VMC) to sell for less than $50,000.
On January 26, 2012, Haas achieved yet another milestone: production of the 125,000th Haas CNC machine tool also a VF-1, and still priced less than $50,000.
Machine number 125,000 is bound for a customer in the Philippines.
Precision parts start with precision fixtures. These blanks will be precisely milled on a Haas EC-400 to create fixtures to hold Haas tailstock castings during machining. By controlling the quality of the fixture, Haas controls the quality of the part. Building quality throughout the entire process is the number one priority at Haas.
The Haas EC-1600 HMC is equipped with a gear-driven 50-taper spindle that provides 450 ft-lb of torque for heavy cutting. The optional Programmable Coolant Nozzle automatically directs coolant precisely at the cutting area, eliminating constant adjustments by the operator.
The concept of a machine that can provide three axes of movement for cutting metal and other materials has changed very little since the dawn of the industrial revolution. These simple, basic tools, however, have benefited substantially from the application of computer technology. The modern VMC uses CNC (computer numerical control) to coordinate both simple and unbelievably complex movements of those three axes. While electronic servomotors can provide axis movements in the tenths of a thousandth of an inch, the amazing performance of these machines is the result of high-precision positioning encoders, high-performance axis drives, and the powerful computer control that coordinates the axis movements and is able to repeat them precisely. Using a computer language called G-code, machining programs can be developed and tested offline, and then transferred to the machine and run with minimal human interaction.
