Undoped yttrium aluminum garnet is an optical material similar to sapphire. Undoped YAG is widely used in UV and IR optics due to its mechanical and chemical characteristics.

The multi-purpose universal milling tool machine 67Е25ПФ1 is designed for performing various milling works in different planes in a wide range of cutting modes. Availability of a great number of elements on the machine makes it easy to work it in tool workshops of machine plants while manufacturing tools, relief stamps and other commodities. The machine is provided with a digital indicating, which is designed for removing the parts of the machine. The worked part can be installed on the table with a vertical working plane or on the angular table with a horizontal working plane. Technical characteristics of the machine, wide range of rotation frequency of spindle and feeding, availability if mechanical feeding and accelerated shifts allow economic working of various parts from different materials, due to application of high modes of cutting and reduction of additional time. Technical potential of the machine can be significantly expanded by applying tools and devices, delivered to special order. By applying cutter, speed and slotter heads and a set of additional tools, it is possible to perform boring, drilling and slotting works on the machine.

Super multipurpose high accuracy milling tool-making machine 6725ПФ1 is designed for performing various milling works in different planes and at different slope angles in large range of cutting modes.

Due to its dielectric and crystallographic properties, sapphire is an outstanding material for producing various wafers for electronic applications. Sapphire is the basic material in LED production, as its crystal lattice allows the growth of an epitaxial layer of gallium nitride (GaN) with fine performance characteristics and a favorable price/quality ratio; also, it is considerably widely used.

High accuracy table milling machine ЕФ55 makes following operations: hole making, screw cutting, horizontal milling by circular, disk, form-milling and other cutters, vertical milling by face-milling, end-milling, keyway-milling and other cutters. Possibility of installation of series of instruments and accessories makes it easy to operate the machine. The machine can be used both in domestic, laboratory and industrial conditions.

Vertical milling head is used for processing details on the plane of a vertical table. It has the possibility to process details in various angles on that plane. It has a mobile spindle for drilling operations. Fastens to the case of the horizontal spindle.
