AC microLine® 880  The Main Technical Characteristics 

  • PETER WOLTERS AC 880 double-side batch processing machine has been designed for high-precision series processing of small and medium work pieces. The AC 880 is designed as a fine grinding machine.

    Machine Features:

    • Like all machines of the AC microLine® series, AC 880 is based on tried and tested core components such as high-precision, pneumatic pressure system, non-contact micro measuring controller, powerful drive technology, and the PLC assisted machine control. Software has been developed by PETER WOLTERS which makes it possible to intuitively operate the machine entirely by menus. The swivel mounted upper base frame allows good access to the machine interior.

    • The machine is available with different epicyclic workholder drive systems, drive powers and wheel speeds to match the widest possible range of work pieces. This ensures optimum machine configuration for every application.

    • AC 880 is available with well-known, tried and tested accessories such as gap formation and alignment device. Accessories such as measuring sensor and post-process measurement provide data for statistical process control and offer process security when processing critical work pieces. DataCare®, the proprietary analysis tool, captures all controller data and thus is the perfect platform for analytic process evaluation, optimization and fault analysis.

    • AC 880 can load and process work pieces with a maximum diameter of 260 mm and a maximum thickness of 100 mm.
  • Long machine life, reliability, profitability, versatility and automation are all prominent features of the AC microLine® series.

    Proven PETER WOLTERS manufacturing standards – Made in Germany.
    • Adapts easily to customer’s application requirements
    • High degree of stiffness and precision
    • Fast – ergonomic loading and unloading, as well as easy tool changing
    • Optimum surface quality, flatness, thickness tolerance and plane parallelism with narrowest tolerances on the work piece
    • Extreme temperature stabilization over the tool surface and therefore constant flatness of the working wheels
    • Reduced cost per piece, shorter loading, unloading, non-productive times
    • Comprehensive, clearly structured screens
    • Excellent machining results due to compliance with freely programmable process parameters
    • Fast response to load changes
    • User friendly, intuitive operation
    • Capable of storing 60 or more processing programs
    • Low operating costs
    • Individual process development, highest productivity
    • Easy to maintain
    • AC 880 can be configured to the respective application and is suitable for fine grinding
    • Top variant features constant-torque servo drives
    • Size of the work piece to process is the basis for selecting the optimum epicyclic workholder drive system. Several variants to choose from
    • Machine comes with suitable filters and cooling components depending on the application
    • Remote maintenance solution RangeCare® via mobile communications or VPN

    AC 880 Automation/ Loading Systems:

    PETER WOLTERS system solutions in hard- and software ensure that all automation components interlink perfectly.

  • Offering precision within the latest technology
