Creep-Feed-, Profile- and HEDG-grinding with the MICRON machine range
The MICRON – machine tools are consequently designed for creep-feed-, profile- and high efficiency deep grinding. Dis-advantageous details, usual with other profile-grinding machines, were eliminated. They are space-saving, compact designed and combining rigidity and dynamic with high-precision accuracy. The machine type “Macro-S”, for example, has a width of only 1500mm but all the properties to perform efficient profile-grinding operations.
MICRON – machines are fitted with high-precision linear guides, ball screws and digital servo-drives on all axes. The modern Siemens 840D CNC machine control system allows free contour formation during grinding and dressing and can interpolate up to five axes simultaneously. The MICRON machine-range is used in almost all sectors of industry for producing components. In the aerospace industry and energy production the machines are used, for instance, to precisely and economically grind blades for turbines, vanes and compressor parts. Profile- and Creep-feed-grinding is also an economical alternative to milling and is used industrial wide where profiles with high accuracy and surface quality have to be manufactured from the solid work piece.

Every ShaftGrind L installed, is the concrete transformation of the requirements specific to the work piece into an optimally designed production concept. It doesn't matter whether you work with one component over several years or if the spectrum of application varies or expands ShaftGrind system with its modular design offers you diversified solutions.
ShaftGrind L can be obtained as a single- or double-slide machine, with a grinding length of 650 mm or up to 1.100mm or as ShaftGrind L synchro. Each slide is equipped with a slewable spindle. Needless to say, the B-axis is available for both sildes. Thus, the ShaftGrind L can be configured completely with one to six spindles that are independent of each other or used simultaneously.
Patented slewable spindle with high speed balancing system ranging from 70 up to 370mm
The second grinding spindle which swivels around the first spindle, offers the unique facility of grinding the concave cam contour with the highest possible precision. The external diameter of the first spindle thereby forms the bearing for the swivelling spindle. This patent, by the application of a general swivelling point, provides the highest precision in the shortest
inervention times possible. The large grinding wheel fixed on the slewable spindle with a diameter ranging from 70 to 370 mm, guarantees a long tool life. When changing the grinding wheel - (depending on the grinding spindle installed) - the balancing system restores the operability in less than two seconds. That is High-speed.

A clear - cut operator - friendly concept was a precondition in the design of the PRECIMAT and PLANOMAT lines. Easy accessibility to the working area was as equally important as the compact design and the simple installation. All machine axes utilize precision ball screws and A.C. servo-motors.

Features:
Three axes automatic grinder with small footprint.
Double V guide-ways are laminated with Turcite-B hand scraped to obtain smooth stick-slip free movements.
The traverse is guided by roller linear guides, with high precision ball-screws and driven by servo motor.
The Y-axis is also guided by roller linear guides, with high precision ball-screws and driven by servo motor.
The flanged cartridge type spindle is supported by 3 pairs of class 7 super precision angular contact ball bearings, preloaded and select-fitted into spindle cartridge.
The automatic re-circulating lubrication system supplies lubricant to all of the guide ways and lead screws as the machine operates.
The external independent hydraulic tank is located outside the machine to be easily accessible for maintenance. Driven by the proportional valve hydraulic system for easy speed adjustment in a range of 2~30meter/min for most surface grinding applications.
Standard oil cooler unit for hydraulic system. Prevents temperature rises and thermal deformation is reduced to a minimum.
