The compact lathe CU-325 is designed for turning work with small parts, this model of the machine can carry out all kinds of turning operations, such as turning cylinders, cones, boring the inner diameters of parts, drilling and threading on parts made of various materials: metals, plastics and wood.
The CU-325 can be used as a training lathe in the workshops of training mechanical workers, the machine can serve as a visual aid due to its simplicity of design, and on practical exercises in turning business.
Also, the CU-325 small-sized lathe is used in small repair shops where turning of parts up to 1000mm long is required. and the diameter of processing over the bed is not more than 325mm. The machine is manufactured in metric or inch version, depending on the needs of the customer. The machine can cut the main types of threads: metric, inch, diametrical-pitch and modular.

By special order, the CU-325 is equipped with:
- Camlock clamping device with spindle nose according to DIN55027/ISO702-III or according to USAS B-5.9-D1/ISO702-II
- Taper ruler for cutting taper threads and turning cones up to 250mm long. and angle up to +/-10 gr.
- Thread indicator for hitting the thread when turning off the queen nut
- Emergency stop pedal
- Digital indication
- lunettes
- Large diameter lathe chuck
- Drill chuck for tailstock
- Machine version with stepless speed control possible
The CU-325 universal lathe complies with European standards for the safety of equipment operation and is equipped with all the necessary elements to protect against injuries to the machine operator and mechanical damage to the equipment.
The machine is equipped with a chuck protection, a spindle band brake, a lead screw protection cover, a tool holder protection, a rear cover along the entire length of the machine.
The electrical equipment of the machine is assembled from components manufactured by Schneider Electric. The electrical wiring, connectors and all electrical elements of the electrical equipment of the machine are placed inside the machine body and protected from mechanical, atmospheric and chemical influences. The main motor and the motor of the cooling system pump are protected against short circuits via safety circuit switches (in the electrical cabinet) and against overload via overcurrent protection (bimetal thermal relays).

One of the most famous machine tools manufactured by the Bulgarian company ZMM Sliven is the CU325 model, designed to perform a wide range of turning operations. In practice, this equipment is effective for the implementation of procedures for:
- turning, both external cylindrical and conical surfaces;
- drilling holes;
- boring holes with special cutters;
- creating threads of any kind, including conical, inch and many others.
Workpieces with a diameter of up to 325 mm can be used as workpieces if they are installed above the bed. However, it is also possible to work with parts with a diameter of up to 445 mm, if a specialized recess in the bed is used.
Additional features of the CU325 lathe
A distinctive feature of the CU325 is the ability to switch and adjust a wide range of basic parameters of the caliper and spindle. Ultimately, this allows you to use a variety of types in your work. cutting tools, as well as to process workpieces from virtually any material.
It is worth noting the constant rigidity of this model of equipment, which has a beneficial effect on the degree of its reliability and durability. The CU325 machines are presented both in the basic version, i.e. with the simplest design, and can be supplemented with various units that significantly expand its scope. Thus, this equipment is convenient to use and allows you to solve a wide range of turning tasks.
