Vertical Turning Center for Optimized Output


What: Vertical twin-spindle turning center
Who: EMAG (emag.com)
Important to note: The nickname of the VL 2 P is the “Nebenzeit Killer,” or, “Idle Time Killer.” Because the objective of the design was to minimize any time that the machine isn’t cutting metal. There are two spindles that are setup so that when one spindle is machining one side of the workpiece, the second spindle loads itself so that the new raw workpiece is ready to go. The turret then goes over to the second workpiece. Explains Dr. Guido Hegener, managing director of EMAG Salach Maschinenfabrik, “Changing workpieces on this machine is unbeatably fast, owing to the fact that the traverse between work spindle 1 and work spindle 2 is minimal. The time needed to load and unload the workpiece runs parallel to the cycle time and therefore has no influence on chip-to-chip times.”
Pertinent data: The machine is designed to handle parts with a diameter of up to 100 mm (it uses a 160-mm diameter chuck). There are two spindles located to the left and right of the machine base and are used for the Z-axis movement.


Large Horizontal Machining Center



What: Five-axis, horizontal, high-speed machining center
Who: Okuma America (okuma.com)
Important to note: The MU-1000H is the kind of machine best-suited for those who are making big workpieces, like those for the off-road and agricultural equipment industries. This five-axis machine has a trunnion table with a 1-m2 pallet. It can handle workpieces that weigh up to 5,500 lb. It can handle parts up to 59.05-in. in diameter and 44.29-in. high. This is a machine for the most-demanding of demanding big-part machining operations.
Pertinent data: The MU-1000H has X-axis table travel of 1,550 mm, Y-axis spindle travel of 1,600 mm, and Z-axis column travel of 1,600 mm. The A-axis trunnion swing is +26° to -115°. There is a two-pallet automatic pallet changer. The 4,500-rpm spindle can produce up to 1,416 lb-ft of torque. The tool magazine can handle 171 tools. The machine is equipped with Okuma’s THINC-OSP P200MA control.


Laser System for Texturing


What: Laser-based system for generating textures on surfaces
Who: GF AgieCharmilles (us.gfac.com)
Important to note: While putting textures on the surfaces of tools for producing such things as instrument panels or trim can be done with chemical etching, according to GF AgieCharmilles that process can produce on the order of three to five layers. The LASER 1000 5Ax can produce from 30 to 50 layers, thereby providing higher levels of detail. The system works on materials including graphite, aluminum, copper, steel, carbide, brass and ceramics. There are no fluids or slurries involved; and unlike machining, there are no chips, either, just dust particles that are automatically extracted from the work area by a vacuum system.
Pertinent data: The LASER 1000 5Ax uses a 20-watt, pulsed Ytterbium pulsed fiber laser (there is a 50-watt option). There are two optical and five mechanical axes. Linear scales and rotary encoders ensure maximum accuracy. There are two front opening doors that provide ready access to the work area of the machine and facilitate loading and unloading of parts with a crane. The system can produce texturing, microstructuring, engraving, marking and labeling of 2D and 3D geometries.
