Zimmermann FZ42 portal milling machine with five-axis, five-sided cutting capability
By using a Zimmermann FZ42 portal milling center, Volvo gets the power and torque needed to cut engine fan cases plus the accuracy to turn the machine tool into a coordinate measuring machine for inspection of finished parts
Located near Hartford, Conn., Volvo Aero Connecticut specializes in the machining of large components: fan cases for aircraft engines and gas turbines, fan and compressor structures, compressor rotors, low-pressure turbine cases (LPT) and military parts, usually from aluminum and titanium, as well as Inconel and Waspaloy. It currently manufactures the largest fan casing in the world, at 3.5 meters (11.5 feet) in diameter, for the massive GE90, the only aircraft engine in existence providing 127,900 pounds of thrust, to power the Boeing 777 line. Volvo Aerospace also produces numerous titanium fan cases for Rolls Royce engines.
With the large workpieces, high material removal rates and challenging geometries inherent in aerospace metals manufacturing, coupled with substrates that are often difficult to machine, such as titanium, there is always a need for powerful machining with superior accuracy. Such conditions present substantial hurdles at aerospace supply companies, as they seek to maintain that delicate balance between these seemingly opposing concepts.
As part of its program for the GEnx engine, to be used on the Boeing 787 Dreamliner, Volvo Aero Connecticut recently added a Zimmermann FZ42 machine tool, a five-axis, five-side portal milling center, to its already impressive manufacturing cells at the Hartford facility. The new machine joins other five-axis mills, vertical turning machines, four-axis machining centers and a deburring robot.
Key features on the FZ42 that led Volvo Aero Connecticut to make this acquisition included:
GE90 engine; Volvo Aero Connecticut made the fan casing, currently the largest of its kind at 3.5m (11.5 foot) diameter
In addition, this FZ42 carries a high accuracy package that provides optimum temperature control of the structural machine parts through the use of a special fiber-reinforced compound in the massive side columns. Also facilitating this process are built-in cooling ducts in the portal and Z-axis slide, independent cooling circuits for the A-axis, C-axis and spindle, ground surfaces on the guideways for the Z-axis and side columns, plus a double-pitch measuring system on the A-axis and C-axis.
During the course of manufacturing, thermal expansion of both machine components and workpieces can substantially impact the positioning accuracy of the machine, the stability of the workpiece and the resulting effect on the finished part dimensions. This unique combination of temperature control and mechanical accuracy in the machine construction were an important deciding factor for Volvo Aerospace in acquiring the FZ42.
According to Martin Thorden, engineering manager at Volvo Aero Connecticut, “These features, combined with the onsite machine set-up provided by Zimmermann, were very important to us, especially on this new GEnx project.” Thorden further noted the importance of the control on the machine, a Sinumerik 840D CNC from Siemens. “We see a very big benefit in how well we are able to control the tool with the CNC. We have been able to use the control to take on additional tasks that were previously handled by our CAD/CAM system.” Specifically, he cited the unconventional approach Volvo Aerospace took in machining the big fan cases. They installed the machine without a rotary table, thus realizing over $500,000 in direct cost savings plus material handling time. As a result of that decision, they believed they needed a top-of-the-line control to probe and accurately machine all the features on the part.
Volvo Aero Connecticut, located near Hartford, comprises three buildings, the largest being 40,000 square feet, where various aerospace and military aircraft components are typically produced from aluminum, titanium, Inconel and Waspaloy.
After machining, Volvo Aero Connecticut can actually transition the machine tool into a coordinate measuring machine for inspection, according to Thorden, owing to the superior accuracy provided by the CNC, as well as the special 90 degree angle heads supplied with the machine, part of the MuST® spindle technology from Zimmermann.
Onboard the machine tool, a massive 120-position tool carriage holds various HSK63 and HSK100 tools that are used to machine the substrates worked here. Inside a series of four side stations, within the machine workspace, four additional specialty tools are stored and used for various operations in the machining and measuring process.
All motors and the drive package onboard the Zimmermann FZ42 at this Volvo Aero Connecticut facility are also made by Siemens.
In a typical machining sequence, the milling head on this machine, equipped with the Zimmermann MuST® spindle system, provides Volvo Aerospace numerous other advantages, according to Martin Thorden. All roughing and subsequent finish passes on any material can be achieved in one set-up, which reduces the preparation time and overall production costs by as much as 10%. There is also no need for additional machines and the corresponding materials handling time. The head design further enables Volvo Aero Connecticut to perform tasks other than milling, using the specialty heads stored on the side stations. Changing the spindle, instead of the milling head, enhances repeatability and further reduces the company’s spindle interface costs, according to Thorden.
The combination of increased accuracies, reduced equipment needs and faster throughput has highlighted this Zimmermann machine installation at Volvo Aero Connecticut.

Steps to take for avoidance of imperfections in the aesthetics and surface integrity of gearworks
Roscoe, IL-Forest City Gear recently disseminated the following tips to its employees and would like to share these ideas with the gearmaking community, as well as users and assemblers of gearworks. This information is provided for reference only and any further questions or comments should be directed to author Fred Young, CEO of Forest City Gear. He welcomes all feedback.
BY: Fred Young, CEO
TO: All Forest City Gear Employees
Recently and historically, we have had issues with gears that suffered from the above conditions, after heat treat. These issues can also appear during hot and humid times, as well. We previously had a sand/vapor blast unit that was used to clean off debris and contamination from gears, prior to further processing.
My suggestions for future handling, based on experience and a reading of the current technology, include the following:
I welcome all your suggestions to further our desire for achieving “Excellence without Exception.” (This is the company motto at Forest City Gear.) I think that if all hands are on the lookout to address the corrosion, discoloration, contamination and pitting issues and address corrective procedures prior to further processing-gear grinding, cylindrical grinding or other machine operations- this will help minimize our overall cost. It is very difficult to address these issues after grinding has occurred, as you all know.
The September/October (2009) issue of Gear Technology had an article starting on page 60 entitled, “Gear Corrosion During the Manufacturing Process,” which focused on issues of pitting caused by corrosion, which can be very serious and ultimately lead to gear failure in operation.
While the article discussed the REM Chemical process of isotropic superfinishing in particular, much of the information is germane to the points above and will contribute to your understanding and resolution of these problems. I encourage you to read it. The watchword at Forest City Gear is that all of us are responsible to be on the lookout and take steps to prevent this situation from future occurrence, to the greatest degree possible. It will be prudent to gather some examples and point out exactly what we are trying to prevent from going out the door, by reviewing it with all hobbing/secondary, shaping and grinding department personnel, at the earliest opportunity.

Using Stotz air gages to validate spindle interface components, this leading supplier keeps quality on highest levels; every part, every time
Stotz USA, LLC, is a leader in air gaging technology, products and quality gaging system integration. According to company president, Chris Koehn, Stotz has achieved that goal by a variety of means, not the least of which has been the loyalty of good customers, who appreciate the value Stotz products brings to theirs. One of those customers is also a longtime friend of Koehn’s and he can say that with complete honesty, because he worked there, long ago.
Advanced Machine & Engineering (AME) of Rockford, Illinois is a world player in high-quality machine tool spindle interface components. As part of the Goellner, Inc. Group, AME enjoys a reputation throughout the machine tool industry for manufacturing the finest power drawbars, spindle shafts, guide bushings, locknuts, hydraulic sleeves, expansion gibs and more. AME components, through their own branded products and those of their brother companies such as OTT Jakob, Spieth and Tschudin & Heid, as well as their “other brother” Hennig, itself a world leader in chip conveyor and machine protection systems, are found on nearly every major machine tool brand.
AME was a customer of Stotz before Chris Koehn ever came to work at the air gaging company. Today, these two market leaders maintain a great working relationship, for all the right reasons. AME demands the highest level of quality in their machining and finishing departments and Stotz air gaging systems facilitate the accomplishment of that goal, every day, according to AME Service Manager, Greg Hobbs. “Air gaging is the only technology we’ve found that’s accurate enough to check the machine tooling and especially the spindle tapers we produce here. That’s a fact. In the past, we’d use hard gages and we still use them, but only for certain OD checks. We’d blue up the tapers, insert them, give them a good twist and do our inspections. Way too much inconsistency. Today, with sophisticated HSK tooling, this method is too hit or miss to be reliable. Air gaging provides dead stops on the test stand and the documentation is unbeatable for validation on the straightness, surface finish and taper angles. Plus, the Stotz system allows us to upload all the data on every part, so we have our favorite word…documentation…for every part we produce.”
Hobbs also commented on the user-friendliness of the Stotz air column. When the program is first input into the column for a part in the AME grinding department, for example, the Stotz column essentially becomes a PLC, providing hard data via the Ethernet connections to the host data base. In this manner, every parameter of every part is documented and recorded. In a classic example of the law of unintended consequences, this process is not only used on the parts run, it’s also used for calibrating the AME machines, in a predictive maintenance function.
At AME, various testing of machined spindle interface and other components is performed both at the machines in the grinding department, in a temperature-controlled 72° environment, plus in the company’s totally environment-controlled in-house testing department, supervised by the company’s Director of Quality, Brad Patterson. He confirmed Greg Hobbs’ observation that numerous other technologies have been investigated over the years for quality checking at AME and that air gaging has been found to be the best and most reliable for this company’s applications, particularly ID dimensions and configuration. Patterson also observed, “The sophistication of the Stotz air column is unmatched in the industry. We get all the data required and we get it in exactly the fashion needed to support our customers. Repeatable results and elimination of error, every time. Plus, the set-up is much faster than on our laser mics, which can’t be used for ID measurement.” Patterson further noted that the replacement of the bluing technique, one he termed a “black art,” with air gaging has brought and keeps AME up to the most current industry standards for quality evaluation.
The typical Stotz air column found here is the Model MSG, with four pneumatic channels or ten LVDT channels operating simultaneously, pneumatic length measuring, user specific programming up to 18 programs per column, full statistical analysis and full data transfer capability within the host network. All info is fed into the AME host computer by serial number, so any job can be quickly retrieved, while historical records on any part produced can be easily called up for evaluation, deviation claims or to dovetail with a customer’s internal quality protocols.
Typically, as AME’s Grinding Supervisor, Sam Schubert, explains, the finished product will rest for 24 hours of soaking, allowing the diameters to normalize. Though statistically predictable for most metal materials, thermal expansion can cause off-normal readings to occur. For checking certain bearing journals or spindle shafts, snap gages are set to accommodate size measurements down to the twenty millionths (0.000020”) range. The acceptable diameter tolerances for most AME products measured are in the 1-2 tenths (0.0001-0.0002”) range.
In cases where new masters are made for setting control values, those values are preset offline and programmed into the air column’s software, according to Greg Hobbs. Stotz typically performs this function for the customer in a remote manner over the Internet, through a proprietary IP address.
Among the many products finished in this grinding department are CAT/ISO 40 taper spindles, HSK test arbors, HSK grind quills, HSK steep taper milling tools and more. Often, older and worn spindle shafts are reverse engineered by AME for retrofits and reman’s. Even in these cases, air gaging is used to evaluate the finish process on the ID taper, as this versatile technology is easily adapted to such applications, according to AME personnel.
Sam Schubert expanded on the use of Stotz air gaging at AME.
“We have a full and very expensive inventory of hard gages with state-of-the-art indicators attached. But the air gages can do so much more. We use them for set-up on the grinding machines and they save us hours, every week. When you run the number of jobs we do here, that translates into substantial, additional work product and therefore more revenue for the company. In terms of reliability, some of the Stotz air gages we run here have been at AME since we began using the technology, nearly ten years ago now.” Schubert also noted the air gaging set-ups on the grinders dramatically reduce the time to first part in his department’s operation.
On one major spindle shaft project for an Asian machine tool builder, who was looking for a local source of supply in America, Schubert notes, AME was confronted with an unusually large quantity run, where tool degradation during the run would normally impact the production at some point. After an initial batch was produced, the machine builder claimed that everything but the taper was satisfactory. Quite surprised by this claim, AME checked all the documentation and determined that the customer’s test unit was actually out of spec, in a case where the error was repeated consistently and thus overlooked. In the end, the AME products were deemed better than perfect, in that instance.
Sam Schubert cites a useful analogy here. “The documentation we can produce from the air gaging procedure is like a birth certificate on every unit we make. All our spindle shafts for customers, for example, can be viewed as a series of genetically identical twins to each other and we’re providing the documentation of their DNA.” Quite a family.
As evidence of their commitment to this technology, Schubert notes that AME is now purchasing air gaging fixtures for all new customer applications. This quality spindle interface manufacturer aims to “keep breathing easy” in their process and product validation, as a result.
“Stotz has been a leader in gaging technology for almost 60 years. We are constantly striving to improve our designs and develop new products to solidify our position as a leader in measuring technology. The Stotz customer base consists of the top manufacturers and suppliers in the machine tool, automotive, aerospace and medical industries,” according to company president, Chris Koehn.
