• 6-position hex turret with 6 toolholders (ø 40), no powered tools, but equipped as a swivel axis (B-axis), double supported with direction logic
• 2 GMN grinding spindles at turret positions T 3 and T 6, speeds approx. 42,000 rpm and 18,000 rpm, each equipped once with a CBN wheel and once with a ceramic pin
• Workpiece feed unit with circulating system via drag frame for workpieces approx. 130 mm
• MARPOSS MIDA – tactile measuring system at workpiece change for pre- and finished dimension
• NORGREN air gap measurement system (?), hydraulic weight compensation of main spindle,
• SMW-Autobloc 3-jaw diaphragm chuck (for easier gripping of raw parts), approx. Ø 250 mm, with clamping monitoring
• HYFRA recooling unit for main spindle cooling and thermal stabilization of machine body, elaborate SEITZ paper band filter system and retractable chip conveyor, cooler for grinding emulsion, oil mist extraction, magnetic separator, central lubrication system, etc.

Vertical CNC lathes offer a thermo-stable design (chips do not fall into the machine bed), fast workpiece changeover times (pick-up system via main spindle), and a stable tool arrangement that also enables non-standard machining operations.
Here, hardened gears were hard-turned and ground.
