    High production grinding Center with a X-travel up to 900 mm long. The enhanced X-travel allows grinding of larged size 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 » read more
    The MACOR-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.

Creep Feed-Grinding / Profile Grinding / HEDG Grinding

MICRON machines are modular CNC grinding centers. They are compact, reliable, and especially designed for Creep Feed-, Profile-, and HEDG grinding. Compared to conventional surface grinding, these processes allow high stock removal rates. MICRON machines, therefore, offer a high level of dynamic rigidity.

macro-3d-rederingDesign

MICRON machines feature precision linear guide ways, ball screws, and digital drives in all axes. The state of the art SIEMENS 840D CNC control allows precision contour dressing and grinding and offers up to 5-axis interpolation.

The MICRON “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
A high level of dimensional accuracy and surface quality – for almost all industry sectors

MICRON 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. macro-work-pieceIn 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.

For most applications conventional or vitrified CBN grinding wheels are used. In certain cases, however, the use of single layer plated super abrasives may be more economical.

MACRO-SK - The Main Technical Characteristics:

  • The MACRO-SK

    The MACRO-SK is a grinding machine especially designed for machining the internal contours of stators, and it sets new standards in efficiency and precision for machining the internal diameter of stators. The machine concept of the MACRO-SK enables the user to grind various types of stators on the machine, e.g. Gerotor and Geroller. The machine has two spindle arms when fully equipped. During grinding, these spindle arms are lowered in a vertical direction into a stack of stators that are clamped in a fixture. The vertical grinding direction proves to be a major advantage in this regard compared to other machine concepts, because the cooling lubricant is channeled specifically into the grinding gap, thus achieving larger grinding feed values. The grinding time, and thus the entire cycle time of the process are reduced by having higher grinding feed rates. The maximum stack height in the fixture is approx. 100 mm, with the benefit that several stators can be ground at the same time, depending on the component thickness.

    The compact, space-saving design reduces infrastructure costs thanks to the small amount of floor space taken up. A completely newly developed acoustic emission system supports precise and economical dressing of the grinding wheels, and is additionally used for initial cut control in order to monitor the grinding process. Optionally, the machine can be equipped with an RFID reader. RFID chips that are integrated into the corresponding fixtures store information about the CNC program number and technology data, for example. As a result, the correct machining steps are performed automatically after the fixture has been loaded.

  • The MACRO-SK is characterized mainly by the following useful features

    • Compact machine design
      • Machine only 1.5 m wide, small footprint
    • Vertical grinding technology
      • Separate spindle arms for roughing and finishing
      • Differently specified CBN grinding wheels
      • The vertical grinding direction permits targeted feeding of the cooling lubricant into the grinding gap with gravity assistance
      • All the stated technological advantages lead to higher stock removal rates and shorter cycle times
    • Clamping station & handling system
      • Loading/unloading of the fixtures during machining lead to a dramatic reduction in the cycle time
      • The clamping station supports precise clamping of the components with repeat accuracy. The handling system provides ergonomic assistance and reduces the strain on the operator
      • The fixture can be exchanged in the machine in only 30 seconds
  • Grinding machine

    • Compact grinding machine with a width of 1.5 m
    • Concrete-filled machine bed. Complete housing of the machine
    • The motors of the spindle arms are water-cooled
    • Precise positioning of the fixtures during grinding is achieved by an indexing table that is coupled to a high-resolution sensor
    • Switch cabinet and auxiliary units connected to the machine in a swiveling arrangement

    Clamping station for loading/unloading components

    • A clamping station mounted on the left next to the machine for exact alignment, clamping and unclamping of the stators in specially designed fixtures. The stators are clamped and unclamped outside the machine space, and these functions are carried out in parallel with the grinding procedure (setup during machining).


    Handling system for fixtures

    • Handling system mounted on a guide rail for ergonomically transporting the fixtures from the clamping station to the workspace and from the workspace to the clamping station.


    Filter system with cooler

    • High-performance filter for filtering cooling lubricant. The filter feed pump delivers up to 150 l/min cooling lubricant. The cooler is mounted on the filter, as a means of saving space. 
  • Software Characteristics
    • Latest CNC technology. Siemens 840D with multi-channel structure and interpolation of up to 5 axes
    • All axes have high-precision linear guides, ball screws and digital drive technology
    • Dressing unit with integrated solid-borne noise sensors. Supports economical dressing of grinding wheels with exact profile accuracy
