box or linear ways, 18–40" (457–1016-mm) swing teach-in type CNC flatbed models, vertical turning lathes with 8–78" (203–1981-mm) chucks, and mul- tiaxis lathes with subspindle and Y-axis milling. Also for the energy industry, Chevalier’s FBL-500 series big bore lathes with 40" swings and up to 157" (3988 mm) distance between centers. The maxi- mum spindle bore is up to 15" (381 mm). At IMTS, Chevalier will introduce two CNC


lathes for machining complex workpieces with competitive pricing. “Machining highly complex parts requires more than simple two-axis machin- ing,” said Herbert Hou, Chevalier’s national sales manager. “We are able to do more machining with the Y axis and live tooling capabilities, thus eliminating handling between machines, for more accurate and consistent production.” One of the Chevalier machines to be introduced at IMTS is the newly designed FNL-220LSY slant bed lathe with live tooling feature, an 8" chuck, 24.4" (620-mm) maximum swing diameter with up to 12.6" (320- mm) maximum turning diameter and a maximum turning length up to 20.1" (511 mm). “Another important automation trend is using


Index Corp.’s MS16 Plus multispindle CNC lathe features six CNC spindles for turning, drilling, milling, tapping, deep- hole drilling, or slotting in each of its six spindle positions for maching bar up to 22-mm diameter. Speed of each of the six spindles can be controlled separately and varied during cutting for each spindle position and each cutting edge of the tool.


even during spindle drum indexing, avoiding secondary processing times. For rear end machining, the MS16 Plus is equipped with a synchronous spindle driven by a hollow shaft motor allowing speeds up to 10,000 rpm. It can move 140 mm in Z at 30 m/min to engage more quickly several


rear end machining tools on the NC cutoff slide with the X and Z axes in succession. To achieve the shortest cycle times possible, the synchronous spindle accelerates to a maximum of 10,000 rpm in less than 0.7 sec.


Multiaxis CNC lathes machine complicated parts Chevalier Machinery Inc. (Santa Fe Springs, CA) makes,


assembles and tests its lathe spindles in-house in the same division as its industry-proven grinding spindles. CNC hori- zontal lathes and vertical turning centers are designed to meet a variety of industry applications. They include 8–32" (203–813-mm) chuck slant bed CNC horizontal lathes with

robots to load parts,” Hou said. “This is especially im- portant for large CNC lathes like the FBL 360B slant bed, which we’ll be introducing at IMTS.” An integrat- ed FANUC robot handles the heavy, large workpieces that its 15" chuck can accommodate. “These are typically large oil industry parts that require turn- ing the ID and OD and drilling holes in the flanges.”


This machine is recognized in the market as FBL-360B, a 45° slant bed lathe with rigid boxways structure and program- mable tailstock. It’s designed for mixed volume, short-run or dedicated high-volume applications and machining bars up to 4.5" (114.3-mm) diameter at speeds up to 2500 rpm with a 35-hp (26-kW) motor with an optional 50-hp (37-kW) /,%* (!ƫ)+0+.Čƫ,.+ 1 %*#ƫ1,ƫ0+ƫāĊĀāƫ"0ġ( ƫĨĂĆĈĈƫ đ)ĩƫ0+.-1!ċƫ


Subspindle lathes get jobs done efficiently Multitasking subspindle CNC lathes from Ganesh Machinery Inc. (Chatsworth, CA) are designed to get the job done efficiently in only one operation. Axial and radial milling features are accurately timed and deburred without building fixtures for follow-on operations and tying up mul- tiple machines and operators. Ganesh multitasking CNC lathe models start with the eight-axis Cyclone 70-3TMY with 70-mm bar capacity and three 16-station tool turrets
