lathe with the functionality of a vertical machining center. It is capable of producing highly complex parts up to 20 mm in diameter and is equipped with a 24-tool automatic tool- changer and vertical tool spindle that performs multi-angle operation on main or subspindle workpieces.


Machines Are Getting More Complex “There is no question that in the Swiss market, the machine side is driving the programming side,” said Gary Hargreaves, vice president, business development, Mastercam/CNC Software Inc. (Tolland, CT). “In the past, the majority of these machines were programmed manually because they were very high volume, running for months at a time, and the user had a lot of time to get the next part programmed. What has changed is that due to CAD/CAM and the ability to program much faster, smaller shops are picking these machines to do much smaller quantities, sometimes as little as a thousand parts and they need faster turnaround,” said Hargreaves. “A lot of people are using these B-axis equipped ma- chines for basically 3+2 type of work where positioning is in three axes and pocket or drilling operations are performed. Even if they are just the drilling and pocketing, they don’t have to set up additional tools, making the machine that much more efficient,” said Hargreaves. “The next step is machining complex shapes and surfaces. We’re seeing an evolution where customers are moving from using it as a programmable fixed axis to actually starting to change the design and look of some of their parts so they have much more complex shapes that require simultaneous motion and CAD/CAM systems to program and machine. Fortunately for us we had a great suite of toolpaths that we were using in the traditional five-axis market that we were able to plug into our Swiss product,” said Hargreaves.


B Axis Offers Versatility Across Product Lines “Our new M4 Series of machines is available in 16, 20 and 32-mm versions,” said John Antignani, executive vice president, Marubeni Citizen Cincom Inc. (Allendale, NJ). “They have three machining sections: a slide on the main spindle; a turret that can work either on the main spindle or the back spindle; and a Y-axis slide which is predominantly for the back spindle. All the machines come with or without B-axis capability, with B-axis capability on both front and back spindles of our machines.” Typical applications for angular B-axis machining include dental parts, instruments for arthroscopic surgery, trauma devices like bone screws with angular features and medical applications that require angular drilled holes. “The newest


thing in the medical industry is double-lead bone screws that require higher pitch angles, so we developed a plus or minus 25° helix angle thread whirling unit for our machines. Thread whirling units are available on all our machines series includ- ing the L, M, and A series,” said Antignani. “The L series is our most popular machine series. Last


year, we introduced the Type 10 machine which has a back spindle Y axis. You can use the Y axis on the front and the back. So we didn’t apply the Y axis to the toolpost, we ap- plied the Y axis to the actual subspindle, allowing the Y axis to be used on the front or the back and producing more simultaneous machining. Also the L20 Type 12, which was introduced at the last EMO show, is a B-axis capable ma- chine, very similar to the B axis that we offer on the M series machine,” said Antignani.


Medical Is Always on the Technology Lookout “Complete milling on Swiss machines is something that is desirable for medical, defense or gun applications, as well as aerospace. The medical market is always looking for more of everything, more tools, more axes, and more capability,” said Bob Erickson, regional manager, Hanwha Machinery America (Franklin, WI). “That’s not unusual. The heart and soul of the market, about 80– 90% of market needs, are satisfied by the standard 7-axis machine, at least what we call 7-axis. We have a C axis standard on the main spindle and on the subspindle.”


“The sweet spot in the Swiss machining market volume is the 20-mm machine, especially for medical applications where the heaviest volume is.”


Hanwha has introduced a large capacity eight-axis Swiss-


type turning center, the XD38HII with Y2 axis. “We have taken our standard seven-axis machine and added a Y axis on the back working station, adding more tooling capabilities. The large capacity eight-axis XD38HII Swiss-type turning center has bar capacity up to 38 mm at the main and subspindle and features high rigidity and cutting accuracy. “The other big buzz in the marketplace is the programma-


ble B axis, which is driven more by aerospace and medical applications. The programmable B axis helps in any type of application where angular drilling, milling, three or four-axis
