The CMT Ursus 250x1500 parallel lathe is an extremely versatile machine tool, suitable for both single machining and small series. This is a used, but well-functioning lathe, which offers excellent performance thanks to its technical specifications and advanced mechanical characteristics.
CMT Ursus 250x1500 lathe model has a center height of 250 mm and a distance between centers of 1500 mm, which makes it ideal for machining medium length pieces. The bar clearance is 50 mm, offering good capacity for working on moderate diameter bars.
The spindle, which allows the rotation of the piece to be worked on, has a maximum workable diameter on the bench of 505 mm and on the slide of 285 mm. Standard motor power is 7.5 kW, ensuring that the lathe has the strength needed to process tough materials. The machine is equipped with 16 spindle speeds, covering a wide range from 23 to 1000 rpm(

The CMT Ursus 250x1500 is mainly used for precision mechanical turning, where it can work on pieces made of steel, aluminum and other metals. Its applications are vast, from the general mechanics sector to the automotive sector, up to small production batches of gears and customized parts.
To use the lathe, place the workpiece between the chuck and the tailstock, making sure it is well secured. After setting the rotation speeds appropriate for the material to be machined (using formulas that take into account the diameter of the piece and the desired cutting speed), the operator uses the appropriate tools for turning. It is important to precisely adjust the longitudinal and transversal 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. It is necessary to lubricate the bench guides and periodically check the wear of the bearings. Furthermore, checking that the feed system and the spindle are in good condition helps maintain the precision of the machining.
When evaluating a used lathe, it is important to examine the wear of key components such as the chuck, slide and motor, ensuring that clearances are minimal and that safety systems are functioning.(

The lathe can be equipped with various accessories, including fixed and mobile 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 pieces to be supported during machining, while the tool turrets simplify tool changes (
Buying a CMT Ursus 250x1500 offers excellent value for money. Despite being used, a well-maintained machine can guarantee years of trouble-free work. This model, in particular, is known for its robustness and reliability over time, making it a long-lasting investment for workshops and mechanical processing companies.
