development of machine models through our control technol- ogy,” said Volovic.
“The Hurco control gives the user both conversational pro- gramming and standard NC, that supports ISO/EIA standards, which means the user can take any Fanuc program or G code program and run it on our machines, which are fully Fanuc compatible. This versatility is important to our customers because they run a high mix of parts. They know the best way to approach each job and we make sure our control technol- ogy supports that approach so they can increase productivity and profitability whether they use NC, conversational, or both. Our NC/Conversational Merge feature lets the user combine both programming types into one program. It enables the user to call an NC subprogram from any conversational program, or add the simplicity of conversational features, such as trans- form plane, pattern operations, or scaling, to NC programs. In addition, our UltiMonitor feature has remote monitoring and remote diagnostics capabilities. It’s a very smart intuitive sys- tem that lets us identify and solve a customer’s problem, often even before the service man arrives,” said Volovic.
company by being both a machine tool builder and a machine tool user. Hwacheon is a supplier of cylinder heads, blocks, crankshafts, and other precision components like gears and spindles to the Korean automotive industry. Hwacheon is also a major supplier of precision machining centers specifically developed for the Korean die-mold industry. “Our moldmaking machine tools feature standard in- tegrated software developed in conjunction with Fanuc for thermal displacement control and compensation. We’re not only thermally measuring the machine throughout its use, but we’re using the information collected to dynamically verify and control accuracy,” said Michael Huggett, president, Hwacheon Machinery America Inc. (Vernon Hills, IL). “We are able to control the kinematics of the machines for contour machining, allowing us to optimize machine performance for roughing, semifinish, and finish machining without going back and forth through a number of different programs.” “While some machine tool builders are getting away from box-way geared headstock machines, Hwacheon is com- mitted to supplying both the heavy-duty geared headstock
Shops are always looking for a better way of meeting their customers’ requirements. They make their choices based on the performance, reliability and reputation of their machine tool suppliers.
At Hurco, evolving control technology is driving machine development. “Our new line of machining centers will feature high-speed spindles 18,000–30,000 rpm, and a new five-axis large machining center will join the three-axis 3.2-m DCX machine.” Two new Hurco machine introductions, the VMX24 HSi and VMX42 HSi machines, equipped with its patented UltiMotion technology, are showing “improvements in produc- tivity up to 40% relative to cutting the part,” said Volovic. “It’s a brand-new way of controlling motion. We’ve taken the posi- tion loops, which normally would be on third party cards, and moved them into the core CNC. This enables us to dramatical- ly improve performance. For example, if you’re in the middle of a tapping cycle, UltiMotion lets you dynamically adjust the cycle while it’s in operation. You can tap at one speed going in and come out many times faster, or continue a cycle after an e-stop and power up without redoing the cycle.”

machines, as well as integral spindle motor, linear guideway machines. There’s a need in the market for manufacturers who want to have heavy-duty reliable machines that are able to take a crash and are powerful for heavy-duty machining as well as able to hold high accuracies in both positioning and finishing,” said Huggett. Hwacheon’s Vesta 1050B box-way geared headstock machining center is capable of heavy roughing cuts as well as fine finish machining. “The 1050B is a true universal machine available with 40 or 50-taper 6000 or 8000-rpm spindles with hydrostatic bearing guideways that produce micron accuracy in a heavy-duty machine,” said Huggett. For high-precision die-mold applications, Hwacheon’s Sirius machines feature 20,000-rpm high-speed spindles for the UM and UL+ models and 12,000-rpm spindle for the UX model. The Sirius ma- chines have integral motor spindles and roller linear guide- ways and are oil-jet cooled.
For five-axis machining, which is gaining popularity and use in the die-mold market, Hwacheon offers the M-2 machin- ing center. “The advantage of five-axis machining for die-mold
