Macro I and Macro S / SI - The Main Technical Characteristics:

  • The MACRO Philosophy

    The MACRO machine range is based on the innovative Moving-Wheel-Head (MWH) concept. All linear movements when positioning and grinding are performed by the grinding head. Compared to conventional moving column and moving table concepts this design arranges the axes in a very compact way, which results in optimum force distribution and minimal thermal variation, properties which result in best possible process control over a long lifespan.

    The most diverse range of areas of application
    MACRO machines are used in almost every industrial sector in which precision mechanical components are found. Wherever there is a need for accurate profiles or slots and/or close finish requirements MICRON equipment offers excellent, economical results. In the aircraft engine and stationary turbine industries, components with poor machinability, such as turbine blades and vanes, can be ground efficiently. Further applications are the highly efficient production of linear guide components, saw tooth profiles, gear racks, gear rings, guides, work holding details, cutting tools, broaches and highly dense ceramic parts. Steering system components and rocker arms are machined in the automotive industry. Stators and rotors in the hydraulic industry are other areas of application.


    MACRO-I

    High production grinding Center with a X-travel up to 900 mm long. The enhanced X-travel allows grinding of large sized work pieces. This machine offers an index table so that loading and unloading can be done during the grind cycle. The index table needs only a few seconds to transport the newly clamped work piece into the grinding area with a simple rotation. Long dwell times are therefore eliminated. This makes the equipment very suitable for multiple machine operation as well as automation.


    MACRO-S / SI

    The MACRO-S was especially developed for use in cellular manufacturing installations. The overall width of the machine is a mere 1500 mm and customization of coolant evacuation and operator stations makes for a very adaptable package when production cells are rearranged. These machines are, therefore, extremely suitable for multiple machine installations and situations where easy adaption to changing production requirements is important. Despite its compact size this machine offers all the same characteristics found in our larger models for highly efficient production grinding.

    The MACRO-SI offers an index table similar to the MACRO-I and facilitates loading and unloading of components parallel to the grinding process. The rigid design of the machine base and frame allows the mounting of most auxiliary systems directly to the machine which facilitates moving the machine as a single unit, an important feature in today’s ever changing production environment.

    The MICRON Dressing Systems

    The dressing of the wheel is a controlling factor for a successful grinding application. For best possible process flexibility MICRON machines can be equipped with a variety of dressing systems ranging from a tiltable table mounted disc dresser to an overhead diamond roll system with or without continuous dress capability. Also available are highly rigid crushing devices. Software is available for CAD assisted creation of disc dressing programs.
