SWISS-TYPE LATHE WITH B-AXIS
In Booth S-8536, the Nexturn SA32XII Swiss lathe from Absolute Machine Tools (Lorain, OH) is a new 32 mm machine that is available with or without a rotary synchronous guide bushing. It features up to 9 total axes (Z1, X1, Y1, Z2, X2, Y2, C1, C2, and optional B) and up to 33 total tools with the B-axis (29 without), including 19 live tools. Machining capacity is 32 mm on the main spindle, 32 mm on the sub spindle, and 210 mm (8 in) maximum turning length in one chucking (60 mm or 2.36 in without guide bushing).

The machine is built for rigidity, accuracy, reliability, and ease of use. The highly rigid one-piece cast iron machine bed is designed using FEM software. Powerful motors for both turning and milling deliver outstanding machining capability. The use of ultra-precision pre-tensioned ballscrews and LM guides produce high accuracy. High speed positioning of 1,260 ipm reduces cycle times. A sliding operator door, as opposed to a lift up style door, provides easy access to the machining area and is drip free.

Powerful live tools provide excellent milling ability. With 1.3 hp and 6,000 rpm, a wide range of milling, drilling, and tapping can be performed.  ER-16 collets (ER-11 for back tools on the optional B-axis) for the live tools provide excellent rigidity. Rigid tapping is standard. The optional B-axis, used primarily for milling, drilling and tapping angled holes, provides 0 to 135 deg of swiveling rotation with 3 front side and 3 back side live tools. The front side tools can be used for both front and face work, doubling the useful tools to 6 possible.

The synchronous rotary guide bushing features a dual bearing structure with high accuracy. It has strong and accurate bearing support on both ends. The guide bushing is spline shaft driven. The guide bushing is necessary for precision machining of long parts. The machine can be ordered without the guide for short parts, reduced remnant length, and the ability to run cold drawn material.

Nexturn Co., Ltd., located in South Korea, is an industry leader in Swiss type CNC lathes and was the first to produce a 38 mm CNC Swiss machine.

BREAKTHROUGH MACHINING TECHNOLOGIES
In Booth S-8986, Chevalier Machinery, Inc. (Santa Fe Springs, CA) will display nine machines, along with a FANUC intelligent robot teamed with a Chevalier heavy-duty horizontal turning lathe to demonstrate increased production efficiency through automation.

A rundown of the nine machines begins with the new FBB-110L series, a T-type horizontal boring mill that expertly handles heavy-duty, high-precision machining with 120 in x 83 in x 80 in machining capabilities. The extra-rigid design of the main machine body and column ensure outstanding structural stability. The fully supported base on the X– and Y-axis assures no overhang or vibration during cutting. The series features a one-piece Meehanite® cast iron base with heavy-duty large box ways on X-, Y-, and Z-axes and is coated with an anti-friction Turcite material for consistent accuracy and smooth movement. The 35 hp, 50-taper, large-diameter, cartridge-type, air-purged spindle runs with a two-speed gear head stock that generates a maximum of 1500 Nm to overcome most tough-material cutting conditions.

The spindle can be extended (W-axis) for deep-hole boring with high-rigidity and superior machining accuracy. The table features a full C-axis contouring with 0.001 deg minimum intervals. It also has a hydraulic break disk plus a locking pin every 90 deg, designed for maximum stability. The rotary table is driven by an AC servo motor with a worm shaft and gear that provides high torque for heavy workpieces. The angular scale is built in the table to assure the accuracy of ± 15 arc-second.

Visitors can See the FBL-360B heavy-duty horizontal turning lathe teamed with a FANUC. The 45 deg slant bed lathe features a rigid box ways structure and programmable tailstock; engineered with ease of access and trouble-free maintenance in mind. The series also comes with a 15 in chuck, maximum swing and maximum turning diameter of 22.4 in and a maximum turning length up to 80 in. The lathe features up to 35 hp AC digital spindle motor with two-speed gear box, spindle bar is 4.5 in diameter and speed up to 2,500 rpm. It’s the best machine in the market for mixed volume, short-run or dedicated high-volume applications.

Chevalier’s new FBL-520D heavy-duty horizontal turning lathe, perfect for machining heavy parts and large pipe threading, is in demand by the energy and aerospace industries. The series features highly accurate machining that can handle rough– and fine-turning operations. The gear box provides enough horsepower for heavy-duty turning. With live tooling capability, this series can save time by milling and turning a part in the same set-up. The series structure features a 45 deg slant-bed design, comprised of single-piece Meehanite® cast iron with a wide-span, ribbed box structure.

For stability and support, the machine provides box guide ways that are 5.1 in wide by 3.1 in thick. A powerful 60 hp spindle motor, which features a three-stage gearbox and generates 3,049 ft-lb of torque, satisfies most cutting conditions of large-diameter work pieces or tough material applications. The 12-station turret is 200 mm thick for deep hole boring and rough turning. The 15 in through hole is perfect for pipe yard threading and meets API and parameter thread standards.

The company also introduces the new FSG-ADS series high-precision, fully automatic, three-axis grinder with a PLC controller. The cutting-edge device provides a grind cycle with rough grinding, fine grinding, spark-out passes and an automatic over-wheel dresser with compensation, which can be added to fully automate the grind process. After the cycle is finished, the table will “park” either left or right of the saddle and at the front to facilitate unloading and loading. The series, which is well suited for mass production and easy to set-up, program and operate features user-friendly conversational programming.

The machine’s spindle can be set to “stop running” or “continue running.” The wheel head can also be set to return to the start position or to park at a reference point. Once the cycle is started, the wheel head moves rapidly to the start point and repeats the grind cycle. If material is required to be removed from both sides, “flip over” can be selected so that the wheel head position is at the finish grind height, which then starts grinding immediately without touching off. The fully automatic grind feature consists of rough and fine grinding cycles, switching from rough grinding down-feed increments to fine grinding down-feed increments at preset points during the cycle. This crossfeed also switches from a rough to fine cross-feed increment, resulting in a finer surface finish and finer accuracy. www.chevalierusa.com
