The milestones of the Weiss success story in the overview: ECO200/GCU350/GCH440 W11 W27/W37/W50 W11CNC We are revolutionizing the W11! Hydraulic-free, axis drives with servomotor and ball screw, technology input of the grinding parameters via touch-screen, automatic parallel dressing with compensation, automatic retraction,... All this with the simple and proven operating concept of the classic W11! Expansion of the machine program with a manual CNC supported cylindrical grinding machine W11CNC Expansion of the machine program with a simple CNC cylindrical grinding machine with manual mode. Optimal use for the production of individual parts, prototyping, training centers and smaller manufacturing companies Further development of the proven WUG21, 4-fold internal turret, new C-axis software for non-cylindrical grinding. Extension of all modules to the latest technology, all modules can be used universally The new building in Neckartailfingen with a production area of 3800 square meters is occupied. The expansion gave us even better production and development opportunities for customer-oriented solutions. Development of a new Torque B axis for fully automatic swiveling of the wheelhead to less than 2 seconds The world novelty WUG21 comes on the market. The revolutionary universal cylindrical grinding machine. - At the push of a button: 100% manual and 100% universal CNC cylindrical grinding machine An independent grinder program is created. Conventional, small CNC, large CNC and production cylindrical grinding machines.

13 Manual - CNC supported machine W11CNC Manual CNC supported external-internal-cylindrical grinding machine Perfect for piece parts, prototypes and small series Conventional universal cylindrical grinding machine with a small CNC control. The extension to the proven conventional W11 machine is the W11CNC. On the basis of the W11 machine we extended the machine with the same technical features by a small CNC control. Why using a W11CNC machine? The following processes are more time-consuming when using a conventional machine: W11CNC Retracting from the workpiece Approaching the diamond and infeeding Setting the truing amount and the speed Returning to the workpiece Setting once again and compensation of the dressing value On the W11CNC machine such work processes are performed automatically. If the diamond and the workpiece are set, you can fully automatically dress, i.e. radii, chamfers, cones and many more. The truing amount will be compensated fully automatically. Other advantages of a W11CNC machine: Grinding several diameters of a clamping process Automatic retracting of the grinding wheel to a safe change position externally and internally Grinding cones and contours in the path operation The classical plunge/longitudinal grinding without CNC program can be performed further on Grinding as with a conventional cylindrical grinding machine Perfect for piece parts, prototypes and small series If a high end CNC machine is too much and a conventional machine is too little, then the solution would be: WEISS W11CNC CYLINDRICAL GRINDING MACHINE

25 Conventional cylindrical grinding machine W11 Conventional external-internal-cylindrical grinding machine Perfect for piece parts, prototypes and small series There are still lot of good reasons in using a conventional cylindrical grinding machine. The assembly of the machine has been optimised for many decades Extremely flexible Very easy set-up Easy and user-friendly Quick clamping on the assemblies for retrofitting Very precise infeed and size accuracy within Readily accessible for the user Applications of the W11 machine Single-item production Manufacturing of prototypes Small series with only little diameter Match grinding Sample production Training and maintenance The proven KARSTENS cylindrical grinding machine concept is the basis of the Weiss W11 machine. KARSTENS has produced more than K11 machines and to this date about 1,000 machines are used worldwide. In 1994, we have started the overhaul or with services of KARSTENS K11 machines. Shortly thereafter, the complete new construction of this machine took place as a so-called classical retrofit. Since 2010, we offer our customers the W11 cylindrical grinding machines alternatively as a new machine or as a retrofit. The complete technique has been further developed and optimised for years, all components comply with most recent machine directives. W11 Due to the continuous technical further development, the W11 cylindrical grinding machine, is today available as a new machine with contemporary technology, which can be individually taken into consideration. In 2018, we revolutionized the W11! We offer the W11 machine in a new, contemporary design. Hydraulic-free, axis drives with servomotor and ball screw drive, technology input of the grinding parameters via touch-screen, automatic parallel dressing with compensation, automatic retraction,...
