What is turning?
Metal turning – is one of the key processes in mechanical engineering and metalworking, in which the workpiece rotates around its axis, and the cutting tool removes the excess layer of material. This method is used to manufacture cylindrical, conical and spherical parts, as well as threads, grooves and other complex elements.
Modern lathes allow for processing quickly, accurately and with minimal costs. The development of technology has led to the emergence of numerical control (CNC), which significantly improved the quality and repeatability of products.
Basic technologies of turning
Depending on the type of parts and precision requirements, there are several main turning methods.
1. Rough machining
🔹 Removing a large layer of material to give the workpiece an approximate shape.
🔹 High feed speeds and deep cuts are used.
🔹 Used at the initial stage of production.
2. Finishing
🔹 The final stage of processing, which achieves high precision and smoothness of the surface.
🔹 Small cutting depths and low feed rates are used.
🔹 Ensures compliance with roughness requirements (Ra 0.8–3.2 µm).
3. Thread cutting
🔹 Creation of external and internal threads on parts.
🔹 Special thread cutters, dies and taps are used.
🔹 Automatic thread cutting is possible on CNC machines.
4. Grinding and boring
🔹 Turning is the processing of the outer surface of a workpiece to obtain the required dimensions.
🔹 Boring – increasing the diameter of internal holes to achieve precision and smoothness.
5. Groove turning
🔹 Creation of grooves, slots and grooves on cylindrical and conical surfaces.
🔹 Special grooving cutters are used.
6. Cutting
🔹 Complete or partial separation of the workpiece from the base material.
🔹 Used in serial production of small parts.
Equipment for turning
There are lathes universal, automatic and CNCThe choice of machine depends on the type of production, complexity of parts and volume of work.
1. Universal lathes
✅ Simple design, manual control.
✅ Suitable for small-scale and individual production.
✅ Used in repair shops and training workshops.
2. Automatic and semi-automatic lathes
✅ Designed for mass production of identical parts.
✅ Can work without operator intervention.
✅ High processing speed.
3. CNC lathes
✅ Fully automated processing process.
✅ High precision and repeatability of parts.
✅ Possibility of processing complex geometric shapes.
✅ Used in serial production.
Materials used in turning
A variety of materials are suitable for turning, including metals, polymers and composites.
🔹 Steel – used in mechanical engineering, construction, and tool production.
🔹 Stainless steel – resistant to corrosion, used in the medical, food and chemical industries.
🔹 Aluminum – light and flexible, widely used in the aviation and automotive industries.
🔹 Brass and bronze – suitable for the production of decorative and electrical parts.
🔹 Titanium – durable but difficult to process, used in aerospace and medical fields.
🔹 Plastics and composites – used in instrument making and light industry.
Best Practices in Turning
1. Choosing the right tool
🔹 Use carbide, high-speed steel or ceramic cutters depending on the type of material.
🔹 For precise processing, use cutters with TiN, TiAlN coating.
2. Optimization of cutting modes
🔹 Select cutting speed, feed and cutting depth according to the material and tool.
🔹 Use cutting mode tables to avoid overheating and premature tool wear.
3. Temperature control and cooling
🔹 Use coolants (oil emulsions, water-soluble coolants) to increase the service life of the tool.
🔹 Monitor the temperature of the workpiece to avoid thermal deformations.
4. Rigidity and precision of machine adjustment
🔹 Use rigid clamping fixtures to prevent vibration.
🔹 Check the geometry of the machine and tool regularly.
5. Automation of processes
🔹 Use CNC machines for serial production.
🔹 Optimize programming with CAM systems.
