LT ULTRA-PRECISION TECHNOLOGY GMBH

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.

On request, we can integrate all of our interferometer systems into our UP machine for quality control in one setting. Be it with a simple strip display or a fully automatic strip evaluation for visualizing the 3D topography. The technical specifications of the intermeter systems are identical to the stand-alone systems.The larger travel range of the MMC900 offers the option of mounting a 6 “interferometer next to the Z axis. After machining the workpiece, the X-table is moved under the interferometer and the surface is measured.

An extensive range of sophisticated diamond-cutting technologies is available, for single piece as well as for series production.

Three-axes turning technology – Our advanced, three-axes turning technology allows us to turn optics having any symmetric geometric shape. An extensive range of sophisticated diamond-cutting technologies is available, for single piece as well as for series production.

Raster-scanning polygons: We manufacture polygons having arbitrary pyramidal angles. We can also machine varying pyramidal angles on individual polygons.

Optical surfaces out of steel without polishing. Ultrasonic assisted diamondturning on steel parts. Pyramidal mirrors, Ellipsoids, Masters, Toroids of all types, Roof mirrors, Conical mirrors, Bifocal paraboloidal mirrors, Waxicons / axicons, Stepped mirrors, Chopper blades, Scraper mirrors, Cylindrical mirrors. Other special shapes are available on special order.

UP milled parts are components that due to their geometric shape can only be produced with 4- or 5-axis machines with high-frequency spindle. The MM machines, developed by LT Ultra, make it possible to produce the parts economically and quickly.
