The ultraprecision turning machine (UP-Turning machine) MTC 650 is currently our largest series machine. Our customers can machine workpieces up to 200 kg in UP quality. The travelling distances are 400 mm in the Z-axis and 650 mm in the X-axis. Workpieces with a diameter of up to 800 mm in diameter (optionally 1000 mm) can be machined. The extended X travel offers more space for additional accessories, further tool holders or special bodies/ constructions. The MTC 6500 is based on a T-shaped natural granite bed. X- and Z-axis slides, as well as the housing of the main spindle are made of granite too. Both slides and the optional B-axis use hydrostatic (oil) bearings. The main spindle features an air bearing and is mounted to the X-slide. Different vacuum chucks for workpieces of up to 800 mm (31.5’’) in diameter are available.

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.

The MMC 600/900 is the basis for a series of machines that, via several accessories and options, can be fully customized to individual needs. In the basic version the machine consists of a main X-axis featuring a linear air bearing (feed axis), a linear roller bearing Z-axis (infeed axis) and the milling spindle (air bearing) mounted on top of the Z-axis. The main application is face milling of optical and mechanical precision components. Several accessories like a Y-axis, an A-axis and/or C-axis are available, thus expanding the range of machinable parts to
microstructures, lenticular structures, spheres, polygons and so on. Accessories, like vacuum chucks, different milling spindles, touch probes for part thickness measurement and even machine interferometers for insitu measurement of workpiece shape, make the MMC 600 and 900 machines an effective tool. Besides further accessories, there is the possibility to make customized solutions, to adapt the machine to your needs.

In the basic version the MMC 5000 consists of a main X-axis featuring a linear air bearing (feed axis), a linear roller bearing Z-axis (infeed axis) and the milling spindle (air bearing) mounted on top of the Z-axis. The main application is face milling of optical and mechanical precision components. A Y-axis is available as an option. Another useful accessory is a second milling spindle, used perpendicular to the first one, thus allowing for the machining of two sides of a workpiece to perpendicularity in one setup. Accessories, like vacuum chucks, different milling spindles, touch probes for part thickness measurement, machine interferometers and other sensors for insitu measurement of workpiece shape and roughness, make the MMC 5000 machines an effective tool. In addition, various sensors are available for measuring of the workpiece geometry and surface quality during the manufacturing process.

Special purpose machines are our specialty. We are able to adapt our standard machines to your needs within a short time or to develop and build completely new machines for your application. Our extensive know-how allows us to accompany you from process development through the design and detailed construction of a suitable machine to measurement, commissioning and the start of production in your plant. In addition, even maintenance or product adjustments if necessary.

Hydrostatic bearings are characterized by practically frictionless movement. The corresponding linear guides are free from stick-slip effects and there is practically no wear on the guides. Gases (mostly air) or liquids (mostly oil) can be used as the carrying medium. Air-bearing guides are ideal, for example, for clean room applications or at high sliding speeds. If oil is used as the carrying medium, higher carrying forces can be achieved with the same size and better damping properties. Various designs are available, which can be customized at any time to meet special requirements in terms of installation space, load capacity, guide length / table diameter, drive type, position measuring system, etc.
