Manufacturing Technology

Methods Machine Tools, Inc, a supplier of precision machine tools and automation, has introduced the new MB 450U simultaneous five-axis bridge-type machining centre, for manufacturing complex parts with quality, reliability and accuracy. New five-axis bridge-type machining centre

With its FANUC 31i-MB5 control, the machine is able to perform full five-axis precision machining of challenging parts, reducing the need for multiple setups. Because the control is available exclusively to Methods due to its partnership with FANUC, Methods machining centres are the only machines from Taiwan that can offer the five-axis simultaneous feature. “In addition to having a unique, powerful FANUC control, the MB 450U machining centre is packaged with comprehensive, high-end functionality for exceptional performance,” said Nicholas St Cyr, Methods machining centres product manager. The FANUC 31i-MB5 simultaneous five-axis control has a 15" colour display and offers a range of standard features that include a 2 GB data server, Manual Guide I, AICC II 600 block look ahead, 1 MB of NC memory and 0.4 ms block processing time. The FANUC control offers collision detection with a 3D interference check and Fast Package III with tool centre point control.

❍ MB 450U machining centre

The MB 450U features a 15,000 rpm Big-Plus 40-taper spindle with air-oil lubrication and a spindle chiller for longevity. A 15 hp hollow shaft spindle motor with 1,000 psi (70 bar) coolant-through spindle prep and couple is also standard. The new MB 450U machining centre includes a large-capacity, dual swing-arm-type 48-tool automatic tool changer. Travel is 400mm (15.7") on the X-axis and 350mm (13.8") on the Y and Z axes. The B-axis has -50° ~ +110° tilting capability and the rotary C-axis has a 360° rotation angle.

Offering high machining stability, the MB 450U has a robust bridge-type construction with thermal compensation including 45mm (1.771") linear roller guide ways in the X/Y axes and 35mm (1.377") in the Z axis, and weighs 6,000 kg (13,250 lb). Heidenhain linear scales in the X/Y/Z axes and Heidenhain rotary scales in the B and C axes offer high-precision part production. Kinematic calibration features a spindle probe with a table centre point calibration ball and kinematic software. A laser tool measurement system detects tool wear, damage and breakage, reducing non-productive time and enabling automated operation. Methods’ machining centres were developed by combining years of engineering and service, long-term partnerships with machine tool builders, and the capabilities of Litz Hitech Corp. Each machine is made to Methods’ design and engineering standards, and is backed by the company’s service and support. All machining centres are fully inspected to meet quality and design specifications, and also to be in compliance with ISO/ASME standards. Laser and ball bar testing ensure the performance and accuracy of each machine. Methods Machine Tools, Inc www.methodsmachine.com

final products. With the new design, only one machine is required. The machine is fed from a single wire coil and the forming machine requires minimal floor space. Changeover time from one model to another is short, and depending on the model to be produced, pro- duction is in the range of 1,200 to 1,500 parts per hour.
