The JUNKER Group including printing rollers, electric motor shafts and others. But its biggest benefit, Zemp notes, is its ability to grind a crankshaft in a single setup, saving users valuable time. When other machines were used, "The crank was moved from one machine to another until it was complete," he recalls. "It used to take eight to 10 hours." JUCRANK 8 can reduce that time to as little as a half-hour, Zemp says. "It doesn't have to be taken off the machine for re-measuring," he says. "All the corrections are made with machine axis motions." JUNKER's recent innovations also include the JUCENTRIC 500, a grinding machine that operates without work piece deflection but with strong accuracy. The machine, Zemp notes, supports work pieces as they are positioned and clamped between centers. When grinding is performed, the JUCENTRIC 500 holds pieces stiff and straight, saving users time. "We can grind a shaft so much faster than using a center-less grinding approach," he says. "A one-and-a-half-inch-diameter shaft that is up to 20 inches in length can be ground in 18 to 25 seconds." International the jucentric 500 is a grinding machine that operates with short cycle times and outstanding accuracy. kets and supply combined production lines," Rochus Mayer, CEO of The JUNKER Group, declares. While production on the JUNKER side was normally used for high speed CBN grinding, "Now we have offerings for aluminum oxide or nonCBN grinding technologies," Zemp says, noting that this gives JUNKER a complete production line. "In the past, we didn't have those products and were only able to provide the CBN grinding technology portion of a production line." Zemp praises ZEMA's hydrostatic machines. "There is no wear and tear [to them]," he says. "They have a very long lifespan with the highest accuracy and reliability." ZEMA's experience in the automotive industry makes it a good fit with JUNKER, since its clientele includes Bosch Auto Parts, ThyssenKrupp, Ford Motor Co. and General Motors. "They are all existing customers worldwide," Zemp says, noting that this played a part in JUNKER's acquisition. A Good Fit JUNKER expanded its market share with the recent acquisition of ZEMA, a grinding machine manufacturer based in Brazil. "We are the majority owner of the company," Zemp says. ZEMA, which was founded in 1953, specialized in CNC grinding machines with conventional grinding wheels for the Brazilian market. The acquisition will bring ZEMA's products to a worldwide customer base, as well as expand JUNKER's expertise in the grinding sector. "Now we can fulfill any customer needs, open up additional mar- Made to Order Based in Nordrach, Germany, LTA Lufttechnik GmbH says it is a technical leader in filtration products.
