DOOSAN MX 2100 - New at IMTS 2008
PUMA MX2100ST TURNS AND MILLS IN A SINGLE SETUP
West Caldwell, NJ – The Puma MX2100ST turn-mill adds true milling capabilities to a powerful Doosan Infracore turning center. The new design provides unmatched flexibility within a complete spectrum of part geometries. From simple turning or milling to complex, simultaneous, multi-axis machining, complex parts can be produced on one machine in a single setup. The dual spindle, multi-tasking Puma MX2100ST is built for heavy and interrupted cuts, long-term accuracy, and superior finishes.
The 12-station turning-tool post is non-lifting to protect the coupling from chips and other contaminants, and indexes station-to-station in a quick 0.2 seconds. Live or static tools can be mounted at any station, and oriented toward either the main or sub spindle. Live tools are powered by a 7.5 Hp (15 min.) motor with a maximum speed of 5000 rpm. The motor is built into the headstock casting, with its spindle fully encased in an oil cooling system. The beltless design eliminates backlash, feedback error and vibration, resulting in lower maintenance with superior precision and finish.
A combined B-axis (tilting) and Y-axis milling spindle maximizes the number of geometries that can be machined without the need for custom rotary tool holders. The Puma MX2100ST can cut, drill or tap above or below the centerline, or mill flats and key-ways. It can machine angular features and provide a solid platform for heavy duty machining. The milling spindle is powered by a heavy-duty 25 Hp motor, and generates spindle speeds up to 12,000 rpm.
Standard on the Puma MX is a floating 40-tool ATC, with a fixed 80 station ATC optional. Tool-to-tool change time is 1.8 seconds.
The bed and guideways are of fine-grain Meehanite casting to absorb vibrations, and inhibit twisting and thermal distortion. Consistent with all Puma machine tools, the bed’s torque tube construction prevents twisting and distortion from heavy cuts, and provides a generous, machine-long conduit for fresh air.
Standard features are included to simplify machine operation. An alarm guidance system senses the main machining points, and alerts the operator of potential problems before operation begins. Second, a machine-airbag function causes the carriage to reverse its movement the moment a collision occurs. This minimizes damage to the machine and to the part. And third, a periodic maintenance function alerts the operator to potential problems within the machine. This prevents unexpected and lengthy downtime while optimizing performance and productivity.
The Puma MX2100ST will be demonstrated by Doosan Infracore at IMTS ’08, booth A-8018.

State needs to train more precision-manufacturing workers
By DEE DePASS, Star Tribune
June 30, 2008
Determined to slay the notion that manufacturing is dead, the Minnesota Precision Manufacturing Association launched a new website Monday displaying job postings, training and scholarship opportunities.
"Everyone thinks that manufacturing is dead, and that is not the case," said association President-elect Dave Fiedler, who runs Checker Machine Inc. in New Hope.
Jamie Nolan, executive director of the association, known as MPMA, said custom manufacturers such as Meier Tool & Engineering, Wilson Tool, andChecker Machine are looking for experienced workers.
"Smaller precision and contract manufacturing companies are thriving. They are growing and are in need of help" finding workers, Nolan said.
If the website is successful, the association will become the "go to" place for workers to find skilled manufacturing jobs and for technical college professors and manufacturing executives to communicate and coordinate job and training needs, Nolan said.
While the website officially launched Monday at www.mpma.com, officials said it will become fully operational in late July or early August, once all 290 member companies and all 32 community colleges get used to using it.
"I would like to see a few dozen jobs by the end of July posted on our website," Nolan said. "I think the job postings will be a great asset for our members. I do get calls from people looking for jobs all the time. Now we just have to get people looking for our website" or calling 952-564-3041 for more information.
There's a problem in the manufacturing industry, Fiedler said. While large corporations are scaling back on workers, smaller and privately held manufacturers are having a hard time finding qualified workers. He said they could face a crisis in five years unless they act now.
"We are losing a lot of people in the next four to five years as the Korean War and Vietnam War veterans retire [from the industry]," Fiedler said. "We are going to face a critical shortage, and this isn't the kind of hiring where a guy can come out of high school and [immediately] work in these plants. They need math skills and technical training communication skills."
Debra Bultnick, the manufacturing workforce liaison for the state's Department of Employment and Economic Development (DEED), noted that a recentstate survey found 52 percent of manufacturing jobs go unfilled in Minnesota because applicants are unqualified.
Nearly half of the manufacturers surveyed failed to communicate their needs with Minnesota's educational system.
MPMA's website and outreach campaign is the latest effort in the state that should help as it showcases welding and computer numerical control training programs for high-tech machining, scholarships for technical school students, and new programs.
For example, the association is getting involved with a new Minnesota Department of Corrections program to train prisoners to become certified metal workers, and another training program aimed at nudging administrative workers into well-paid second careers in machine shops.
The MPMA also works with DEED, the Minnesota Job Skills Partnership, the Manufacturing Educators Coalition and MnSCU.
Doosan Puma Turn-Mill Centers
PUMA MX TURNS AND MILLS IN A SINGLE SETUP
West Caldwell, NJ — The Puma MX series turn-mill adds true milling capabilities to a powerful Doosan Infracore turning center. The new design provides unmatched flexibility within a complete spectrum of part geometries. From simple turning or milling to complex, simultaneous, multi-axis machining, complex parts can be produced on one machine in a single setup. The dual spindle, multi-tasking Puma MX is built for heavy and interrupted cuts, long-term accuracy, and superior finishes.
The 12 station turning-tool turret is non-lifting to protect the coupling from chips and other contaminants, and indexes from station to station in a quick 0.2 seconds. Live or static tools can be mounted at any station, and oriented toward either the main or sub spindle. Live tools are powered by a 7.5 Hp (15 minute) motor with a maximum speed of 4,000 rpm. Polar coordinate, helical and cylindrical interpolations are standard.
Depending on the Puma MX model selected, the turning spindle is powered by either a 25Hp, 35Hp or 40HP motor and driven at speeds from 3,000 to 5,000 rpm. The motor is built into the headstock casting with the armature on the spindle O.D. This beltless design eliminates backlash, feedback error and vibration, resulting in lower maintenance with superior precision and finish.
A combined B-axis (tilting) and Y-axis milling spindle maximizes the number of geometries that can be machined without the need for custom rotary tool holders. The Puma MX can cut, drill or tap above or below the centerline, or mill flats and key-ways. It can machine angular features, and provide a solid platform for heavy duty machining. A highly rigid, three piece curvic coupling locks at 7.5 deg. increments, while the RGC provides extra rigidity in 0.001o increments. The milling spindle is powered by a heavy-duty 20Hp or 25Hp motor, and generates spindle speeds up to 10,000 rpm.
Standard on the Puma MX is a floating 40-tool ATC, and a fixed 80 station ATC optional. Tool-to-tool change time is 1.5 seconds.
The bed and wrap-around, rectangular guideways are of fine-grain Meehanite casting to absorb vibrations, and inhibit thermal distortion and twisting. Each guideway is induction hardened, precision ground, and, before hand scraping, coated with Rulon 142 fluroplastic resin to reduce friction and eliminate wear. Three linear guideways on the upper carriage Z-axis provide rigidity and alignment during the toughest cuts without lift or torsion that might otherwise compromise accuracy. Consistent with all Puma machine tools, the bed’s torque tube construction prevents twisting and distortion from heavy cuts, and provides a generous, machine-long conduit for fresh air.
Each axis is driven by a large diameter, double-nut Tsubaki ball screw, selected for its combination of accuracy, speed and feed thrust. An electric torque limiter protects the ball screws and minimizes damage in the event of a crash.
Among the standard features of the Puma MX is its automatic tool setter to measure tool offsets. The offsets are automatically computed and fed into the controller, eliminating the risk of data entry errors. Also included is the Doosan Infracore Tool Monitoring System, which monitors spindle and axis load – both overload and underload - while the axis is feeding. Loads exceeding the wear settings either initiate an alarm, or switch automatically to a redundant tool. Exceeding the tool-breakage-load stops the machine and alerts the operator.
Puma mill-turns are available with dual spindles as the Puma MX2000ST, MX2500ST, and the MX3000S for parts as large as 21.7:” diam. with maximum lengths from 40.2” to 60”. A single spindle model with programmable tailstock is available as the Puma MX2500. The controller is a Fanuc 18i-T.
DOOSAN INFRACORE TWIN-TURRET, TWIN-SPINDLE TURNING CENTER PUTS MORE TOOLS IN THE CUT SIMULTANEOUSLY
Summer 2007
West Caldwell, NJ — Doosan Infracore’s new PUMA TT1800SY high-performance turning center features upper and lower turrets, equal-capacity opposing spindles, and high-speed, wraparound rectangular guideways. With twice the tools in the cut, and twice the parts being cut simultaneously, productivity can be almost doubled. Y-axis motion and simultaneous feed control on the upper turret enables complex machining processes, such as circular and cylindrical interpolation, to be cut in a single setup.
With double-tool holders, the Puma TT 1800SY’s twin 12-station turrets can house a total of 48 BMT 55P tools, with live tooling at any station. Their quick-response servo drives reduce station-to-station times to 0.15 seconds. This quick indexing time, combined with a 1,575 ipm Z-axis rapid traverse, shave additional seconds from cycle times. Each axis is driven by a digital AC servo motor. These high torque drive motors link directly to the ball screws, eliminating intermediate gears, resulting in quick, responsive slide movement that’s free of backlash.
The left and right spindles are driven by a 30 Hp (25 Hp continuous) integral motor, at speeds up to 5,000 rpm. The motor is surrounded by an oil jacket cooling system to ensure consistency and precision through the widest range of cutting conditions.
The Puma TT can also be specified as a twin turret, with a programmable tailstock replacing the second spindle. The tailstock has a travel of 27.75” along wide, wraparound, rectangular-type guide ways. An additional 5.9” is available through quill travel.
Puma TT machines are constructed on heavily ribbed, Meehanite castings. Their 45o slant bed design allows easy access to the spindles and turrets, while torque tube construction provides a through-the-machine conduit for fresh air, while preventing twisting and deformation. The maximum turning diameters are 9.05” on both spindles. Maximum turning length is 9.1”. Bar capacity is 2.6” diam.
Standard features include a safety window on the front door, swiveling operator panel, and a belt-type oil skinner to eliminate tramp oil from the coolant. Also included are an absolute positioning coder, air blast for chuck jaw cleaning and the Doosan Infracore tool monitoring system. Control is with a Fanuc 18i-T.
HIGH PERFORMANCE DOOSAN INFRACORE TWIN-TURRET TURNING CENTER
Summer 2006
West Caldwell, NJ — The new Doosan Infracore PUMA TL-series turning centers from Doosan Infracore feature upper and lower turrets, and a programmable tailstock for high production machining. With two turrets cutting simultaneously, cycle times can be significantly reduced. Work capacity is 9.4” dia. x 23.6” long on the model TL2000, and 39.3” long on the TL2500. Bar capacities are 2-5/8” on the TL2000 and 3” on the TL2500L. Both models are designed for heavy and interrupted cutting, high accuracy, and superior surface finishes.
The two turrets house a total of 20 (12 upper + 8 lower) tools. Their quick-response servo drives reduce station-to-station times to 0.2 seconds. This quick indexing time, combined with a 945 ipm Z-axis rapid traverse, shave additional seconds from cycle times.
The spindle is driven by either a 30 Hp or 35 Hp integral motor, generating speeds of 5,000 rpm or 3,500 rpm respectively. An oil jacket cooling system surrounds the motor to ensure consistency and precision through the widest range of cutting conditions.
The tailstock features MT#4 center with spindle bearings built into the 3.94” diameter quill. The heavy-duty tailstock travels along wide, wraparound, rectangular-type guide ways and has a generous 4.7” quill stroke. The body can be positioned by programming body unclamp and drive pin engagement with the upper turret.
Both models are constructed on heavily ribbed, Meehanite castings to help dissipate heat and absorb vibrations. Their 45° slant bed design, a characteristic of Puma turning centers, allows easy access to the spindle and turrets, and improves the flow of chips and coolant. Torque tube construction, another Puma characteristic, eliminates torsional stresses associated with heavy cuts, and provides a through-the-casting conduit for cool air.
Standard features include an automatic tool setter to compute tool offsets without skim cuts, and a tool monitoring system. A belt-type oil skinner to remove tramp oil from the coolant, and electric torque limiter crash protection are also standard.
