Machining to 9 Pages 77 to 92 High Performance CNC Turning Centers High Effciency Vertical Machining Centers The NTV158 series of vertical machining centers from YCM Americas, Inc. offers a high rapid feedrate with large Y-axis specially designed for moldmakers and job shops. The Z-axis dual ballscrew drive system and large roller type guideways on all axes ensure perfect accuracies at high feedrates and is suitable for various heavy cutting applications, according to YCM. With a unique, YCM-patented, T-base structure, the machine footprint can be reduced effectively while an overhang-free table movement is supported by a high-rigid base to ensure dynamic accuracy, with heavy loads on the table. With YCM's uniquely designed IDD 10,000-rpm spindle, depending on the NTV158 ensures inline direct transmission and is proven to maximize both spindle and tool life even under harsh working environments, the company states. A high-speed axial movement with roller type guideways provides dynamic accuracy, durability and rigidity. Double nut high precision Tsubaki ball screws are directly driven by a servo motor to efficiently eliminate axial backlash and vibration. NTV158 models include a YCM Control by Fanuc™ with high performance AC digital servo and spindle drives with super precision absolute positioning encoders.

All FEELER machines include extensive design and engineering by Methods, and are backed by Methods' application expertise, support, and extensive network of technology centers, the company reports. The FEELER FT-Series includes four models—FT-200, FT-250, FT-350 and FT-350L. For exceptional rigidity when performing heavy duty cutting, each of the models has a single-piece structure with boxways, 45-degree slant bed and robust base, the company notes. For maximum integrity, FEA analysis is used to ensure a solid machine base with excellent overall structural rigidity and stability. According to the company, additional new design features include a more rigid Z-Axis and tailstock rail for maximum support and accurate tracking. The FT-Series includes a new spindle head stock with a FEELER sleeve-type spindle, and the latest high-rigidity servo turret—including clamping with curvic coupling for stable and swift tool changes. For excellent multitasking capabilities, 7 1/2 HP milling motor with 51.6ft-lb torque is provided, the company states. FEELER FT-Series from Methods offer a reliable FANUC 0i-TD control and 12-station turret. Customers can choose from four different gear boxes as well as two spindle types. The spindle sizes range from 2,500 rpm to 4,500 rpm; and offer chuck diameter sizes from 8" (210mm) up to 15" (381mm). Bar capacity ranges from 2.6" (65mm) to 4.5" (115mm). Maximum turning diameter is offered from 13.0" (330mm) to 25.0" (620mm); and maximum turning length from 21" (530mm) to 60.2" (1,530mm), the company notes. The machine's weight ranges from 9,925 lbs (4,500 kg) to 21,500 lbs (9,750 kg)—depending on the model. A BMT-65 tool system features a solid interface for tool holding. A servo programmable tailstock is standard. For maximum machine component longevity, a fully enclosed CE cabinet prevents dust and fumes from entering. The Methods-FEELER CNC Lathes and Turning Centers include the HT-Series, FTC-Series and FT-Series. The full range of FEELER machines encompasses Vertical Machining Centers, Turning Centers, Bridge Mills and Boring Mills.
