Jun 27, 2002 RZ 400 precision gear grinding machine's main column, that carries grinding spindle and slide, rotates 90° for wheel change and another 90° to perform wheel dressing operation. Gear profile modifications can be made with few keystrokes, without need for diamond discs. It has gearless planetary drives, acoustic sensing for alignment of dressing diamonds, and low noise shifting that produces random surface structure on teeth.

Feb 04, 2002 Electronic GP 300 ES can change over from spur to helical gears, or from one helix angle to another without having to first change guide to accommodate new gear. This eliminates timely changeovers for mechanical and hydrostatic helical guide systems. It uses backlash-free direct drive under CNC control, so any helix angle within stroke rates and length can be created by changing CNC programs.

Nov 09, 2001 PHOENIX® II 275 HC CNC Bevel Gear Cutting Machine is designed to machine gears with pitch diameters up to 275 mm. While it can accommodate wet cutting processes, it is well-suited for dry machining. Cutter spindle and work spindle are mounted directly to column, and cutter spindle pivots to create root angle, rather than mounting workspindle on rotating base. Machine includes direct-drive spindle motors and is available with FANUC 160i or Siemens 840D CNC.
