Turning machines

The MTC (Micro Turning Center) series of machines was designed according to the needs of ultra-precision turning. By using diamond tools, optical surface quality can be achieved on a wide range of materials like crystals, metals and plastics. Thus, in combination with the C-axis (option), allowing for the turning of nonrotationally symmetric / free-form workpieces (Slow Tool).

An optional tool setting camera can be mounted to the main spindle housing, using an industrial pallet system for the connection, to allow for an easy and accurate remounting. Tool holders and a mechanical interface for the in process camera, as well as different measuring devices like 3D-touchprobes or LVDTs can be mounted to the Z-slide.

When using the rotary table (option), its faceplate is used to mount all the tooling and measurement equipment, offering additional capabilities to the system, such as using the B-axis as a tool turret. The rotary table can also be used to keep a constant cutting point on the tool (3-axis machining, Single Point Turning). Furthermore, the rotary B-axis can be used to selectively change the cutting point if the tool is worn out.

Besides many other accessories, that make the MTC series an all-purpose tool, there is the possibility to make customized solutions, to adapt the machine to your needs.

  • Hydrostatic (0il) bearings
  • Granite machine base
  • Active machine leveling and active vibration isolation system
  • Form measuring system
  • Integrated tool measuring system
  • Process camera
  • Form tolerance: < 150 nm within 100 mm dia.
  • Roughness: < 2 nm (Ra)

The ultraprecision turning machine (UP-Turning machine) MTC 250 (Micro Turning Center) has a lightweight construction of the moving parts and thus enables the machine axes to be used in a dynamic mode (Slow Tool). This machine is our standard machine with the smallest footprint.

The travelling distances of the X- and Z-axis are 250 mm and provide the machining of workpieces up to 500 mm in diameter.

The MTC 250 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.

Besides many other accessories, that make the MTC 250 an all-purpose tool, there is the possibility to make customized solutions, to adapt the machine to your needs. Please do not hesitate to contact us.

The ultraprecision turning machine (UP-Turning machine) MTC 350 (Micro Turning Center) combines dynamic use with an increased work space, thus resulting in a wide range of products to be manufactured.

The travelling distances of the X- and Z-axis are 350 mm and provide the machining of workpieces up to 700 mm in diameter.

The MTC 350 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. In addition to the X- and Z-axis there is the option to have an additional linear axis. This A-axis allows to do micro milling or raster flycutting operations on the machine.
