AC microLine® 1250  The Main Technical Characteristics 

  • Peter Wolters AC 1250 double-side batch processing machine has been designed for high-precision series processing of work pieces. Due to its modular construction, AC 1250 can be used as a fine grinding and honing machine.

    Machine Features:

    • Like all machines of the microLine© series, AC 1250 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 PC assisted machine control. Software has been developed by Peter Wolters which makes it possible to intuitively operate the machine entirely by menus. Swivel mounted cabinet and frame allow access to the machine interior.

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

    • AC 1250 is available with well-known, tried and tested accessories such as gap formation, alignment device, and dosing system for fine grinding compound. Accessories such as measuring sensor and post-process measurement provide data for statistical process control and offer process security when processing critical work pieces. "Data Care", the proprietary analysis tool, captures all controller data and thus is the perfect platform for analytic process evaluation, optimization and fault analysis.

    • AC 1250 can load and process work pieces with a maximum diameter of 320 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 (hysteresis-free)
    • User friendly, intuitive operation
    • Capable of storing 60 or more processing programs
    • Low operating costs
    • Individual process development, highest productivity
    • Easy to maintain
    • AC 1250 can be configured to the respective application and is suitable for grinding and honing.
    • Top variant features servo drives.
    • Size of the work piece to process is the basis for selecting the optimum rotating device. Several variants to choose from.
    • Machine comes with suitable filters and cooling components  depending on the application.
    • AC1250 can be linked with manual, semi-automatic or fully automatic loading systems.


    AC 1250 Automation/ Loading Systems:

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