EC 2015 – Sept. 15-17, Booth 1747 134 MMS January 2017 mmsonline.com MODERN EQUIPMENT REVIEW Spotlight: Turning REDESIGNED GANG-TYPE LATHE DELIVERS LONG-TERM PRECISION The Wasino G-07 high-precision lathe has been redesigned to employ the unified DMG MORI design. The machine's gantr y-type toolpost is said to reduce cycle times by achieving "zero indexing time." Featuring a long, 490-mm X-axis travel, the lathe is said to provide the high accuracy of a gang-type lathe, enabling more accurate finishing and hard turning. The G-07 lathe has a symmetrical structure with respect to the spindle center, and the mini- mum distance between the axis travel reference guide and the spindle helps minimize the effects of heat. Induction-hardened, single-piece hori- zontal slideways integrated on the bed provide good vibration damping, high thermal stability and high rigidity. The slideways' resistance to chatter makes it possible to lower the position of the center of gravity between the floor and the feed system, promoting stable machining accuracy over the long term. The flat-V slideways on the Z axis and dovetail slideway on the X-axis dovetail ensure high rigidity and straightness. The ballscrew support bearing is placed as close to the spindle as possible to suppress thermal displacement; a reliable pre-tension structure is also employed to boost precision. Such features combine to enable the G-07 to achieve dimensional accuracy of 3 microns even from a cold start and circularity of 0.5 micron, the company says.
