Jim Lorincz
By Jim Lorincz Contributing Editor, SME Media

There’s still plenty of good old fashioned metal (and material) removal going on in tens of thousands of US metalcutting shops and plants around the country. A visit to the huge South Hall at McCormick Place during IMTS 2016 is where you will find booths overflowing with advanced conventional turning and milling machines, multitasking CNC lathes, towering boring mills, and precision Swiss automatic lathes under power along with the automation needed to carve more-efficient production out of industries as diverse as aerospace, automotive, medical, job shop and contract manufacturing, and general engineering. In the two short years since the last IMTS, a lot has happened, but nothing more than the emergence of the disruptive technologies ushered in by the Internet of Things (IoT) and the potential of hybrid additive/subtractive machine technology. It all adds up to a revolution, not an evolution. Capturing real-time data from machines and processes facilitated by the MT Connect standard will significantly advance smart manufacturing and provide real-time intelligence about machine OEE, predictive maintenance, and ultimately plant-wide efficiency.

Mitsui Seiki’s Vertex 55X-H hybrid additive head can 3D print parts from a design or add material to an existing part.

There’s probably more than one grizzled old metalworking industry veteran who would like nothing better than to be around long enough to see how smart manufacturing and hybrid AM technology will play out. Here’s some of what you can expect to see.

Mazak Exhibit Emulates Advanced Smart Factory

“Our booth will be symbolic of a Mazak Smart Factory, combining all the elements of advanced manufacturing technology,” said Brian Papke, chairman, Mazak Corp. (Florence, KY). “This year will mark the largest amount of advanced technologies we’ve ever brought to IMTS. We will demonstrate a host of new high-level developments in full digital factory integration, a Smart Box digital integration launch platform, and Industrial Internet of Things (IIoT) connectivity—in addition to new machining and automation systems—all of which will prepare manufacturers for the next industrial revolution.”

Mazak will show over 20 advanced manufacturing cells and systems. Among these will be the company’s latest developments in multitasking and five-axis machine tools with single-setup, done-in-one part-processing capabilities crucial for tomorrow’s smart factories. Additionally, the company will unveil the next generation of its hybrid additive/subtractive multitasking technology, along with new software and accessories that give multitasking machines even more functionality and multiple-process power. Various types and levels of smart factory automation will be demonstrated, including gantry systems, robotics, the proven Palletech system and the new compact Vertical Stacking System for standalone machining centers.

“We will demonstrate the user-friendly programming capabilities and processing speed of our Mazatrol SmoothX and Mazatrol SmoothG CNC controls,” said Papke. “Smooth controls feature new algorithms that result in faster speeds, finer accuracy, and better finishes, producing machining results that are as much as 7–30% faster with the biggest impact on the most complex five-axis machining.” For automated tool changing, Mazak is introducing its new Tooltech compact tool system that stores big, heavy and large-diameter tools within a very small amount of required floor space. As a shop’s tooling needs increase, Tooltech’s storage capacity can easily expand to as many as five levels and the capacity to hold 250 tools.

All the new and advanced machining and automation systems in the Mazak IMTS booth will be under power and running real-world part demonstrations. For example, Mazak will unveil its new Variaxis i-800T multitasking machine and demonstrate it cutting an aerospace jet engine blisk using 5ME’s cryogenic cooling system. Other applications experts from Mazak’s Value Inspired Partners (VIP) program will be on hand to discuss and demonstrate total manufacturing solutions and part-processing improvements.

Mitsui Seiki Strategy Based on High-Precision Machining

CAP-A-Metalcutting-Makino-Automation-Cell-768x509.jpg
Makino will display a variety of automation cells.

Mitsui Seiki USA Inc. (Franklin Lakes, NJ) will exhibit three machines that demonstrate its ability to provide high-precision technology that meets the most exacting machining standards for aerospace. “All three machines are our Vertex-style machines that machine a decimal point tighter,” said Scott Walker. “One machine will have a direct drive [DD] motor machine that is capable of grinding like a jig grinder in addition to precision milling capability. The second machine will be a single-blade Vertex milling machine aimed at the Ti-Aluminide market, and the third will be the new Vertex 55X-H additive/subtractive machine with a powder metal feeder and a laser assembly head with shield gas being demonstrated machining a damaged jet engine blade in need of repair.”

The Vertex 55X-H, which is making its debut at IMTS, is built on a precision Mitsui Seiki VMC platform with a spindle-adapted laser DED (Direct Energy Deposition) / powder feed nozzle. The nozzle loads into the toolchanger like any conventional tool and is changed automatically via the CNC program prompts. For milling the 3D-printed surface or internal feature, a milling/drilling tool replaces it and aspects of the workpiece are machined conventionally. The process is under full adaptive control as the part is made, moving back and forth between additive and subtractive while maintaining common center line integrity to produce the intended surface or feature with sub 15-µm accuracy within the work envelope. Users can choose either a CAT or HSK 15,000–30,000-rpm spindle. “The Vertex 55X-H hybrid machine is well-suited for the repair of a number of different types of airfoil parts, such as high-pressure turbine and compressor blades, low pressure blades, blisks/IBRs and impellers for the aerospace, power generation, and oil and gas industries,” said Walker. ”

Hurco Invites Visitors to Race to Profitability Indy-500 Style

Hurco will capture the spirit of Indianapolis, the headquarters location of the company since its founding in 1968, and the home to the single largest one-day sporting event, the Indianapolis 500. Visitors will be able to race RC IndyCars on a Hurco created scaled-down version of the Indianapolis Motor Speedway, complete with a blimp and leaderboard. Attendees can check www.hurco.com/imts to see what hours open racing will take place and/or to register for a spot to race competitively. Prizes will also be announced on the website.

“In addition to sponsoring IndyCar team Ed Carpenter Racing [ECR] with drivers Ed Carpenter and Josef Newgarden, the team uses our CNC machines at their machine shop,” said Maggie Smith, marketing manager. “Since we know that both racing and machining rely on speed, power, and precision to succeed, we thought the race to profitability theme would be a fun way to showcase how Hurco CNC machines make our customers more profitable,” said Smith.

Hurco will exhibit several new models of CNC machines in addition to their newest technology invention that will enable owners of Hurco vertical machining centers to transform their WinMax part programs to a 3D-printed rapid prototype directly on their CNC machine using an optional spindle-powered wireless accessory. The 3D print head adapter, which extrudes plastic PLA filament, will be exhibited at the Hurco booth and at the Additive Conference.

Turned Parts Complete in One Clamping

“Machining parts complete in one clamping from bar stock or castings is still the primary strength of much of today’s turning-based machining,” said Jeffrey Reinert, president and CEO, Index Corp. (Noblesville, IN). “Our technology enables manufacturers to drop precision parts complete in one setup, run untended, get more machining hours out of the week, 24/7, if they so desire, and be competitive globally. And that’s where our advanced technology for US-based companies comes into play with products like our new extended version of the Index MS16 Plus.” The six-spindle CNC lathe simultaneously accomplishes two or more operations, dropping complete parts in very short cycles. The machine features six independent liquid-cooled, hollow-shaft CNC spindle drives each capable of 7000 rpm, a main spindle drive with increased stiffness, and hydrostatic guide bushings on each carrier slide, which eliminate wear and transmission of vibration to the tool. “With liquid cooling, spindle and drum cooling is accomplished away from the work area, making the machine more stable, able to run at higher rpm, with more torque, if needed, according to the needs of the material being cut,” said Reinert. Typical applications for the MS16 Plus are found in the automotive, aircraft, hydraulics, and valve industries.

The new INDEX G220 Turn-Mill Center which will be demonstrated generating bevel gears, includes a motorized five-axis 18,000-rpm (max.) milling spindle and a tool turret with Y axis, providing maximum machining flexibility for turning and milling complex parts in a single setup from bar stock up to 90-mm diameter, chuck diameter of 210 mm. Users in the precision parts industries including automotive, aerospace, and mechanical engineering will benefit from the high-accuracy done-in-one capability of the machine.

The new TRAUB TNL32-11 sliding/fixed headstock automatic lathe, to be introduced at IMTS, has a headstock moving in the Z axis, an upper and identical lower turret with X, Y, and Z axes, and a counter spindle movable in the X and Z directions. The innovative machine offers a new front working attachment which sits on an additional cross-slide moving in the X and Z axes, providing the user with further, freely positionable tools and enables the use of up to three tools, simultaneously and independently of each other. The 11-axis machine saves machining time—especially for components with a high proportion of drilling.

DMG MORI Offers an Innovative Path to Production

DMG MORI (Hoffman Estates, IL) will demonstrate 27 high-tech machine tools and innovative technologies, including the US premieres of the Ultrasonic 20 linear and the Sprint 32|8 as well as the locally produced DMU 50 with PH 150 and NHX 4000 2nd Generation with RPP. “We want to show a path to production that gives visitors a broader view of how a common part can be manufactured using a number of different ways of automating the process,” said Adam Hansel, CTO, DMG MORI. “For example, one way might be using a turning center and three-axis machining center. Another way might be using a five-axis machine with a pallet changer, or the same mill and lathe tended by a robot with peripheral processes like deburring, laser marking, or gaging added. And still another might be with a mill-turn multitasking machine with a built-in NC robot.”

DMG MORI will highlight production in its North American manufacturing facility in Davis, CA, which has a production capacity of 100 machines per month that includes horizontal machining centers, five-axis universal milling machines, vertical mills, and CNC turning centers. At IMTS, customers will experience live demonstrations on locally manufactured machines and be able to take a virtual tour of the factory, discovering how DMG MORI builds its machines seamlessly from design to production.

To support its global customer base, DMG MORI will highlight its global Spare Parts availability with over $240 million worth of inventory and more than 275,000 unique spare part numbers in the global logistics network, DMG MORI guarantees a fast worldwide delivery directly from the manufacturer. The inventory includes new parts as well as replacement parts. There is also spare part availability for early models from 1970 or later.

Innovative areas include additive manufacturing with two DMG MORI machine models, the Lasertec 65 3D and Lasertec 4300 3D, hybrids that enable machining of complex components. In the field of additive manufacturing DMG MORI uses a blown powder deposition welding process with laser, as it has long been used in principle for repair work in the tool making or turbine technology branches. In this process the powder is melted onto the base material by the laser beam. DMG MORI also builds up layer by layer, but only uses the powder where it is actually needed. This reduces the necessary quantity of powder significantly.

Okuma Opens its Customers to Possibilities

Okuma America Corp. (Charlotte, NC) will exhibit 17 machines from its variety of high-tech and core product categories. “If you take the time to count, the machines have a total of 72 axes,” said Tim Thiessen, vice president-sales. “Inside of the booth, we will detail how our customers can benefit from the Open Possibilities that our OSP control and broad product line offer. Our high-tech products include vertical and horizontal multitasking machining centers and five axis machining centers and vertical turning lathes.” Okuma will have demonstration parts in the booth for aerospace and medical applications. “If we’re making an aerospace part on a Multus, we’ll also feature an automotive or medical on a video screen being machined on the same machine,” said Thiessen.

CAP-B-MetalcuttingDoosan-LPS-768x375.jpg
Doosan’s compact LPS II linear pallet system will be shown with an HP 5100 horizontal
machining center and 12 pallets.

At IMTS, Okuma’s MU-5000V vertical machining center will be shown cutting an actuator and intake manifold on steel, aluminum and titanium. The MU-5000V is excellent for five-axis multisided machining. It features standard ball-screw cooling and a highly rigid left-right, mobile trunnion table to support high-precision and heavy-duty cutting power in a compact footprint. Maximum productivity is achieved with a wide array of automation options. The unique design places the pallet changes at the back of the machine, allowing easy connection to a Palletace flexible manufacturing system, pallet pool, large capacity ATC and robots to deliver high productivity in addition to high accuracy.

Simulators in the Okuma booth will demonstrate the intuitive nature of the OSP control. “We’ll also be showing our machine tool apps which can be made by the user, much like smart phone apps. We make a number of apps as do our distributors and customers. They are basically little applications that may address a certain need or desire to get certain information out of the control or create a special procedure like a lock-out procedure. We’ll also be showing our OSP Suite, which may seem to be like an app, but they are kind of like widgets on the control, a calculator, a materials calculator, messaging, or an eco-friendly suite recognizes that certain motors and pumps can be turned off if not needed to save money or be more energy efficient for savings,” said Thiessen.

Three A’s Hold Sway at Methods Machine Tools

According to Bryon Deysher, president and CEO, Methods Machine Tools Inc. (Sudbury, MA) focuses its product development focus on the three A’s: Automation, Additive, and Accuracy. “With builder partners such as Nakamura-Tome, FANUC, Yasda, Kiwa, Feeler, and now 3D Systems, we are in a unique position to bring the latest technologies to both subtractive and additive solutions for our customers serving aerospace, defense, medical, firearms, and automotive industries.”

To enable its customers to deal with the shortage of skilled labor in the manufacturing workforce, Methods Machine has expanded its Methods Automation group to provide customers with more unattended processes with Nakamura, FANUC Robodrill, FANUC EDM, and Feeler Products. Nakamura, Yasda, and Kiwa offer built-in automation.

“Additive manufacturing solutions in both metal and nonmetal composites from 3D Systems enable our customers to meet these demands of time-to-market pressure,” said Deysher. “We will feature the most advanced 3D Additive manufacturing solution with the new ProX DMP 320 Metal Printer. Feeler will feature a variety of prismatic part and full five-axis solutions, and FANUC will introduce new models in high productivity solutions on both EDM and Robodrill platforms—all intended to meet critical time-to-market requirements.”

Methods Machine’s expanded automation offerings will include FANUC robots providing automated deburring and inspection systems in addition to our normal machine tending solutions. “We will also be displaying a high-speed gantry system on a Nakamura WT150 platform and a Kiwa KMH300 six-pallet system as solutions with built-in automation,” said Deysher. “The Yasda PX30 will address both production high-accuracy requirements with positioning feedback resolution of 0.1 µm and untended capability with 33 pallets and full five-axis capability. We will also feature three Yasda Jig Borer class platforms for Die Mold and ultra-precision requirements.”
