The CMT Ursus 250x1500 is primarily used for precision mechanical turning, where it can work on steel, aluminum, and other metal parts. Its applications are wide, from general mechanical engineering to the automotive sector, all the way to small production runs of gears and custom parts.
To use the lathe, the workpiece is positioned between the spindle and the tailstock, ensuring it is securely fastened. After setting the rotation speeds appropriate for the material being machined (using formulas that take into account the workpiece diameter and the desired cutting speed), the operator uses the appropriate turning tools. It is important to precisely adjust the longitudinal and transverse feed parameters, which in the case of the CMT Ursus vary between 0.06 and 0.84 mm/rev and between 0.03 and 0.042 mm/rev, respectively(
).
A lathe like the CMT Ursus 250x1500 requires regular maintenance to ensure efficiency. Lubricate the table guides and periodically check the bearings for wear. Additionally, ensuring the feed system and spindle are in good condition helps maintain machining precision.
When evaluating a used lathe, it is important to examine the wear of key components such as the spindle, slide, and motor, ensuring that play is minimal and that safety systems are functional(
).
The lathe can be equipped with various accessories, including fixed and movable rests , self-centering chucks, and manual or automatic tool turrets, making it a flexible choice for various types of machining. The rests, for example, allow long workpieces to be supported during machining, while the tool turrets simplify tool changes .
Buying a CMT Ursus 250x1500 offers excellent value for money. Even if it's used, a well-maintained machine can provide years of trouble-free service. This model, in particular, is known for its robustness and reliability over time, making it a lasting investment for workshops and machining companies.
