Metal Cutting: Cells and Machining Centers

By SME Media Staff

Manufacturers can ramp up productivity

There will be more than one new machine introduced at IMTS 2006 that will be billed as a China beater, or as an India and rest-of-Asia beater, for that matter.

U.S. manufacturers ranging from entrepreneurial job shops to Tier suppliers and general engineering manufacturers will have a chance to hone their competitiveness with the latest advanced technology. The usual ways to sharpen that edge are to reduce labor content and cycle times, extend untended manufacturing capability, and deliver parts machined complete in one setup to required precision-finish quality.

“There is wide-ranging interest within the machine-tool industry about the need for higher precision and better surface finish,” says Richard Curless, VP-product and technology development, Cincinnati Technologies (Hebron, KY). Curless believes that some of the answers lie in better software to control machines, advanced simulation techniques, stiffer machines for hard-metal machining, and multihead solutions for advanced multitasking capability. “All of these will be exhibited at IMTS,” he says.

The emphasis on automation will continue with an added twist. “Manufacturing systems are going beyond traditional delivery and load/unload mechanisms to package a whole manufacturing solution including the machine tool, inspection system, parts cleaning, and even packaging,” Curless explains.

To meet the impending ramp-up in the aerospace industry for machining titanium, superalloys, and other difficult-to-machine materials, Cincinnati Technologies is introducing its MEGA5-800 five-axis HMC. The MEGA5-800 features twin ballscrew-driven Y-Y-Z axes a B-axis table, and an A-axis tilt spindle with 180° sweep to make five-side machining, as well as full five-axis contouring, possible. The IMTS machine is configured for optimized machining of titanium. The specific machine and process enhancements include: the application of damping technology to change the machine’s natural frequency and reduce chatter; a new coolant and coolant delivery system adjusted for titanium machining; new tooling that delivers extended life cutting titanium; and a specialized method of chip evacuation and removal.

Cincinnati Technologies, comprising Cincinnati Machine, Giddings & Lewis and Cincinnati Automation & Test, is a group of the MAG Industrial Automation Systems company (MAG-IAS; Sterling Heights, MI), serving the aerospace, heavy equipment, power generation and general machining markets.

The MAG-IAS group of companies will flex its newly configured $1.2 billion-muscle in an exhibit space of 100 x 270′ (30.5 x 82.3 m), and display machines ranging in price from the low 20s to as much as $3 million.

Rounding out the MAG-IAS groups are Powertrain Technologies (Cross Hüller Ex-Cell-O Lamb), Special Machining Technologies (Hülle Hille, Hessapp and Witzig & Frank); Maintenance Technologies for all MAG aftermarket service and support; and the Blue Technologies.

The principal brand name in Blue Technologies is Fadal (Chatsworth, CA). Shown will be its VMCs and a full line of CNC lathes that is being added, VMCs from Cincinnati Machine UK, HMCs in 500 and 630-mm sizes, and 250 and 400-mm chuck-size inverted-spindle VTLs.

Two of Fadal’s three new HMCs, the HMC-400 and HMC-500, will be introduced. A third size is the HMC-630. The HMCs will be branded with the Fadal name in North America, and with the Cincinnati name in Asia and Europe.

The new lineup of machining centers and CNC lathes gives Blue Technologies a portfolio of machines that it says covers about 50% of the range of machine tools consumed in the US. It includes CNC lathes between a 6–18″ (152–457-mm) chuck size, VMCs with Y axis from 14 to 35″ (355–890 mm), and HMCs from 400 to 630-mm table size.

Hardinge Inc. (Elmira, NY) is expanding the breadth of its product offering by introducing what it calls baseline products in both turning and milling. “We have always been known for our high-end super-precision products,” explains Pat Ervin, president, chairman and CEO. “We are adding the baseline products to enable us to serve all of our customers’ requirements for small-to-medium cube-size parts,” he says.

Included in Hardinge’s baseline product are its Bridgeport XV-Series 710 and 1000 machining center. The Bridgeport GX 1000B machining center is being introduced in a box-way version for heavy machining operations and high metal removal rates, effectively putting an end to the need to argue linear guide ways vs. box ways as Hardinge now offers both.

The timing is right for IMTS. “Business is good,” explains Thomas R. Dillon, president, Mori Seiki U.S.A. Inc. (Rolling Meadows, IL). “The industry and the economy are both at a point where people are eager to invest in technology, and have the time to thoughtfully and carefully consider their options. And, for Mori Seiki, we will use IMTS to demonstrate our commitment to R&D and the resulting technology.”

Dillon is referring specifically to the Driven at the Center of Gravity (DCG)-design technology that was developed to improve rigidity and vibration dampening and increase accel/decel of its VMCs and HMCs. At IMTS, Mori Seiki will unveil the NT5400 DCG/1800XZ mill-turn machine, the NX3000 DCG production machining center, and the NMV5000 DCG five-axis machining center.

The NH4000 DCG will be displayed with the Mori Seiki CPP (Carrier Pallet Pool) for increasing the efficiency of parts machining while minimizing setup in untended production. Five of the 21 machines that Mori Seiki exhibits will employ automation to some degree, but with the provision that the automation doesn’t interfere with the visitors’ ability to see what’s going on in the demonstrations.

“Our engineers have challenged themselves to showcase the most compelling capabilities of our machines,” Dillon says. “Specifically, we want to emphasize part processing that is not routine. We want the demonstrations to be meaningful to our customers and create maximum impact—we want them to be as exciting as a Fourth of July fireworks display.”

Chiron America Inc. (Charlotte, NC) will exhibit a twin-spindle machining center for high production parts manufacturing, as well as multiaxis machines for medical device and precision-parts machining. “Manufacturers have a very real thirst to reduce manpower costs, as it is a big portion of the cost-per-part equation,” explains Chiron’s Ross Clark. “Automation in the form of six-axis robots, for example, is one answer and one that is becoming more price competitive, and the talent, at Chiron, to successfully integrate the systems, is readily available.”

“Twin-spindle machines give manufacturers the ability to reduce manpower while increasing production with a machine that is about 30% more expensive than a single-spindle machine, without multiplying the number of operators, systems, and fixturing needed to support it,” Clark says.

Chiron will exhibit an updated version of its FZ12KW Magnum CNC vertical machining center with pallet changer and fast tool changes for mid to high-production of parts that have a 6″ cube (152.4 mm) or smaller. For medical device manufacturing, CHIRON will be displaying a small milling turret-type milling center, the FZ08KS, and also Chiron’s Mill 800 five-axis traveling column machine with a compound tilt rotating table for larger medical parts and some automotive applications.

Scott Walker, president, Mitsui Seiki (USA) Inc. (Franklin Lakes, NJ) believes there is a resurgence of interest by manufacturers in more expensive, better-built machine tools that are in demand for machining higher-value workpieces. His company will be highlighting two types of precision technology: jig boring machines and the three and five-axis Vertex VMC with and without automation. The Vertex VMCs are designed for precision machining of mold and die and aerospace parts. A five-axis trunnion-style HU635X machining center that is able to provide versatile machining of very complex parts to close-to-jig-bore tolerances will also be exhibited.

High-precision machining is key to the desire of manufacturers to find lean solutions to maintain their competitiveness, says Walter Schnecker, president, Datron Dynamics Inc. (Milford, NH). “The real secret to competitiveness is how the manufacturer uses the real estate that he’s working with on the machine bed, and the tools that the machine tool builder supplies him with,” says Schnecker.

Datron will exhibit its entry-level EZ Raptor high-speed machining center with 60,000-rpm, 600-W high-frequency spindle and built-in workholding for quick changeover of parts on its 30 x 40″ (762 x 1016-mm) machine bed. Tools are typically 1/4″ (6.35 mm) or under. The EZ Raptor is capable of multi-function milling, drilling, routing, engraving, and thread milling. Thin stock such as plastic foils 0.001″ (0.0254-mm) diam to large aluminum sheets 0.250″ (6.35-mm) diam can be securely held by the machine’s Vacu-Mate vacuum table.

Mal Sudhakar, VP, Mikron (Lincolnshire, IL) says that manufacturers are looking for the flexibility to respond quickly to their customers. “We’re addressing the whole area of automation by offering affordable systems that are built right into the machines. Our HSM Series machines feature table chucks with pallets instead of T-slot tables. Various clamping systems are available including 3R-Dynafix, Erowa UPC, as well as larger 600/800-mm pallets.”

The HSM 600(U) and HSM 800 ProdMod high-speed machining centers include a tool-storage tower with large tool storage capacity in a compact footprint. The ProdMod tool tower is built as a circular tower with racks and a robotic arm, offering 120, 170, and 220 tool positions. Because a large number of tools can be accessed quickly, fast setup changeover times can be achieved. Chip-to-chip time is about 5 sec.

Mikron will also exhibit its HSM 400U ProdMed and HSM 400U ProdMed Dental machines for manufacturing medical implants, including dental and orthopedic, and surgical and general instruments. Smart machining modules monitor measurements to check and evaluate tools and workpieces, inspect the tools for breakage, measure the workpiece, and document all results—all critical quality functions in the medical device manufacturing industry.

Makino Inc. (Mason, OH) will focus its exhibit on the various elements that go into process solutions. “It’s a total recipe and we’ll show how the elements such as the machine tool, cutting tools, toolholders, CAD/CAM programs and applications experience and know-how come together to produce effective and efficient processes,” explains Makino’s Mark Rentschler.

Makino will focus on lean manufacturing cells and systems, the variety of different types of automation and systems displayed in conjunction with Makino machines, and demonstrations of machining difficult-to-machine materials such as CGI and titanium. Makino will be demonstrating machining CGI with its new 800-mm HMC for machining cylinder-head and block production.

“In general, if you are making high-volume, low-valueadded parts in America, that’s a pretty hard thing to do today,” says John Roth of Haas Automation Inc. (Oxnard, CA). “What we see is that the American entrepreneurial jobshop market is very good at making lower-volume, higher value-added parts.

“For example, in America at this point, you’re probably not making water pumps for pennies apiece for a major car company. What you’re probably doing is making water pumps to keep that factory running when their overseas supplier fails to deliver.

“That’s where Haas equipment shines. The user can set that job up quickly, program it, edit the program, set offsets, get the chips out, turn the job around quickly, and move on to the next hot job, explains Roth.”

Haas Automation will have its usual full house of new and current machines at the show (more than 60 at last count), including the EC-630 HMC, a large capacity, highproduction machine that is being tested, tweaked, and readied for shipment.

The following products are representative of the machining centers and cells that will be displayed in theMetal Cutting pavilion of IMTS 2006. — James Lorincz
