AD&P; > May 2015 > On Mfg 44 ON MFG ON MFG p The Vertex 55X II vertical machining center includes an ultra-high accuracy package suitable for tight-tolerance mold and die work. p Methods Machine Tools, Inc. has expanded its Feeler FT-series turning centers with the FT-250SY, featuring Y-axis travel and an additional sub-spindle. p The addition of a stable and rigid Y-axis on the Doosan Lynx 220LSY multitasking turning center eliminates the need for secondary machining operations. Compact Turning Center Ofers Single Setup Machining What: Lynx 220LSY multitasking turning center Who: Doosan ( doosan.com ) Important to note: This compact, high-speed turning center features milling and drilling capabilities of the Y-axis, thus eliminating the need for secondary machining operations. The Y-axis increases the number of workpieces that can be completely machined without expensive custom rotary tool holders and enables the milling cutter to machine above or below centerline. Because the machine can eliminate the need for secondary operations on another machine, like a milling machine, there are predictable throughput and consistent part quality. Pertinent data: Depending on the model, the bar capacity is 2 or 2.628 in., and the chuck size 6.5 or 8 in. The X, Y and Z travels are 8.07, 4.13 and 22 in.; the rapid traverse rates are 1,181, 394 and 1,417 ipm. The machine is equipped with a 20-hp AC motor spindle. There are 12 turret stations for BMT 45-type toolholders, and 24 index positions. A 1.25-in. boring bar can be accommodated. The sub spindle, positioned by a ball screw and servo motor, enables the complete machining of parts in a single setup. Mitsui Seiki Expands Vertex 550-5X Series What: Vertical machining centers, Vertex 55X II Who: Mitsui Seiki ( mitsuiseiki.com ) Important to note: Vertex 55X II is a series of six vertical machining centers that consists of several confgurations based on table sizes and types, ranging in dimension from 9- to 15-in. in diameter. Rotary axis drive systems are high-torque geared or direct-drive. An enhanced ultra-high accuracy package suitable for tight-tolerance mold and die work and other precision component applications is available. The machine features a cast-iron bed for rigidity and thermal stability; guideway mounting surfaces are hand-scraped for volumetric accuracies. Automation systems are also available for on-machine inspection. Pertinent data: A new 30,000 rpm spindle joins 15,000 and 25,000 rpm options. The HSK-80 taper spindle connection for heavy-duty machining is available to compliment the HSK-63 and 40-taper tool interfaces. Positioning accuracy in X,Y,Z axes is 0.000040 in. while the A-axis is ±6 arc seconds and the C-axis is ±4 arc seconds. X,Y,Z strokes are 21.7 x 23.6 x 19.7 in. High-performance CNC Turning Center What: Feeler FT-250SY CNC Turning Center Who: Methods Machine Tools ( methodsmachine.com ) Important to note: The Feeler FT-250SY features a Y-axis with 3.9-in. (±1.9 in.) travel, and an 8 in. chuck diameter sub-spindle (20 hp, 4,500 rpm) in addition to the primary 10 in. chuck diameter spindle (30 hp, 3,500 rpm) to provide more capacity benefts. The single-piece structure with boxways, a 45°slant bed and robust base provides the vibration dampening needed when turning hard materials, including interrupted cutting. Pertinent data: The FT-250SY has an X, Y, Z travels of 8.2, 41.3 and 3.9 in. There is a heavy-duty, 12-station turret. The BMT-65 tool system features a solid interface for tool holding. The machine comes standard with a Fanuc 31i-TB CNC control. A fully enclosed CE cabinet prevents dust and fumes from entering the machine thus maximizing machine component longevity.
