Methods MB 450U Performs Simultaneous Five-Axis Machining
The MB 450U bridge-type machining center from Methods Machine Tools performs simultaneous five-axis work thanks to its FANUC control. The FANUC 31i-MB5 has a 15" color display and includes 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 CNC also offers collision detection with a 3D interference check and Fast Package III with tool centerpoint control.
The 15,000-rpm Big Plus, 40-taper spindle is equipped with air-oil lubrication and a spindle chiller for longevity. The 15-hp hollow-shaft spindle motor is equipped with 1,000-psi (70-bar) coolant-through spindle prep and couple. The dual swing-arm-type automatic toolchanger can hold 48 tools. Travels measure 15.7" (400 mm) on the X axis and 13.8" (350 mm) on the Y and Z axes. The B axis has -50 to +110-degree tilting capability, while the rotary C axis has a 360-degree rotation angle.
For machining stability, the 13,250-lb MB 450U has a bridge-type construction with thermal compensation. The machine is equipped with 1.771" (45 mm) linear roller guide ways in the X and Y axes and 1.377" (35 mm) ways in the Z axis. Heidenhain linear scales in the X, Y and Z axes and Heidenhain rotary scales in the B and C axes deliver precise motion. Kinematic calibration features a spindle probe with a table centerpoint calibration ball and kinematic software. A Laser Tool Measurement System detects tool wear, damage and breakage, reducing non-productive time and enabling automated operation.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
A provider of machine shop training offers these questions for benchmarking metalworking knowledge.
Different tools and machining strategies have driven this shop to seek new efficiencies beyond its most demanding work and most capable machining center.
