    The standard MACRO creep feed grinder provides a X-travel up to 600 mm long. The torque tube design machine base guarantees superior vibration dampening and thermal stability. Spindles are available with different speed and power ranges to best match the application. All spindles feature liquid cooled motors, and high speed HEDG spindles offer liquid cooled bearing packs as well. This further enhances thermal behavior and consistent production results.

    The machine is equipped with 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.

  • MACRO-I and MACRO-S / SI

    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.

The MACRO Series

Flexible CNC grinding centers with a modular construction:
Highly precise – economical – user-friendly

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.


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.
