Milling machines

The MMC (micro milling center) and MMC H (micro milling center hydrostatic) series machines were developed according to the needs of ultra-precision milling. The difference between the two series is primarily the bearing type of the axis. While the MMC H series has hydrostatically linear bearings, the machines of the MMC series are equipped with aerostatic (air) bearings. The selection of the most suitable machine series / ultra-precision milling machine depends on the products to be manufactured.

The main application of the MMC series is primarily in the production of flat (plane) optical surfaces or precision parts by means of flycutting. With various accessories, the range of parts can be extended to microstructures, lenticular structures, spheres, polygons, etc.

The MMC H series has high speed tool spindles for the production (milling) of Microstructures, free-form surfaces, lens arrays, mold cavities. The machines are also available with a tilt / swivel unit for 5-axis UP machining of workpieces. Additionally or alternatively, of course, flycutter can be installed in the MMC H series.

– Automatictool setting system

The MMC H (micro milling center hydrostatic) series machines were developed according to the needs of micro and ultra-precision multi-axis machining.

To create ideal conditions in terms of rigidity and damping for multi-axis machining, the series was equipped with hydrostatic (oil) bearings. By using diamond tools, optical surface quality can be achieved on a wide range of materials like crystals, nonferrous metals and plastics, even with complex geometries.

Similar to the MMC 600/900 air bearing machines, the basic setup can be equipped with various accessories. The basic setup consists of 3 linear axes and can be upgraded by additional rotary, tilt or spindle axes to 4, 5 or 6 axes. Accessories, like different spindles, vacuum chucks, palleting systems, 3D touch probes for workpiece measurement, tool changer and automated tool setting, allow an effective use of the machine.

Besides further accessories, there is the possibility to develop customized solutions, to adapt the machine to your needs. Please do not hesitate to contact us.
