TUR 800 / 930 / 1100 MN.

The high precision ballscrews for X & Z axis are mounted on high precision bearings to enable sensitive movement. The drive for Z-axis is transmitted to the ballscrew via cogged belt from a Siemens AC servomotor, located on the left-hand side of the machine. After stress relieving treatment and precise machining all bed castings are equipped with hardened guideways which results in a long-life accurate operation of the lathe. The headstock is also based on a modern compact design. The heavy duty spindle is supported by a combination of double-row cylindrical roller bearings and double-direction angular contact thrust ball bearings - a system which provides the highest precision and rigidity for heavy loads and superior surface finish.
