VFT-ultra The fully automated VFT-ultra generator offers outstanding performance based on Satisloh´s Fast Tool Technology. It offers full free-form capability and additional features as autocalibration and a second fast tool axis. Tool spindle Direct driven motor spindle VFT-ultra: 0 - 22.000 rpm continuous viscosity grease Tool reception: ABS® 32 Workpiece spindle Direct driven motor spindle with air bearings 0 – 6000 rpm workpiece reception: collet chuck for Satisloh blocking system, Ø 43 mm Workpiece: Ø 85 mm Throughput:* up to 60 FF lenses/h upt to 90 spheric/toric lenses/h *depending on materialmix and geometries Control High resolution real-time continuous path control 15´´ touch screen with interactive user interface based on Windows™ USB interface located at user panel Tools PCD turning tool: VFT-ultra: Ø 66 mm Specific turning tools made of PCD, CVD, and natural diamonds for organic materials Working ranges Concave milling: -14.5 dpt, turning up to –30 dpt Convex (milling and turning): +30 dpt Materials CR 39, Polycarbonate, High Index Materials Energy Requirements 8 KVA, 16 Amps, compressed air: 6 bar Dimensions (w x d x h): 1100 (1470 with loading system) x 1970 x 1960 mm / 43 (58 with loading system) x 77 x 77 inches Weight 2800 Kg / 6181 lb Interfaces TCP/IP, RS 232, remote diagnosis via optional modem Options Modem Cooling system Coolants & other consumables All-format software 2nd fast tool Auto calibration Surface geometry measurement At first the patented FastProcessing disc cutting method – known from V-Series Generators – reduces the diameter, pre-edges the lens and generates the surface in only one cycle. Then the fast-tool turning axis processes a ready-to-polish surface, perfectly suitable for fast flexible tool polishing. The benefits: Fully automated lens processing with integrated loading system High productivity, low cost per lens Unique: automated system set-up and tool calibration (optional) Optimized, enhanced tool accuracy or avoid tool changes for different materials by 2nd fast-tool axis First step: the patented FastProcessing method speeds up processing by diameter reduction, pre-edging, and generating the lens surface in only one cycle prior to fast tool turning. Second process step: Single point turning with fast tool axis generates accurate and smooth lens surface. Fully automatic operation: The VFT-ultra robotic loading system increases efficiency and reduces costs. Unique: Fully automated axis and tool calibration (optional)
