Complete guide to choosing a CNC lathe

In the industrial world, technological advances are constantly pushing back the limits of productivity and precision. The CNC (Computer Numerical Control) lathe is one of these. This numerically controlled machine tool has become indispensable for the manufacture of complex, precise parts. Whether you are a professional looking to renew your machinery or a technician looking for high-performance equipment, SAMO can help you choose the right CNC lathe.

What is a CNC lathe?


Before choosing a CNC lathe, let's look at the theory. First of all, a CNC lathe is a modernised version of the conventional lathe. A conventional lathe relies on human manipulation. A CNC lathe, on the other hand, is powered by a numerical control system. This machine tool executes machining movements programmed with unequalled precision using computer codes - in particular the G code:
  • A spindle, which rotates the workpiece.
  • A carriage for movement.
  • A tool turret for rapid tool change.
  • A CNC controller, the brain of the machine, where programs are read and executed.

The advantages of a CNC lathe

So why opt for a CNC lathe? Because they revolutionise machining thanks to complete automation! But their main advantage is their high level of precision. This makes it possible to produce complex aeronautical parts or medical implants to minute tolerances. But that's not all. A CNC lathe is capable of continuous operation. It can, for example, mass-produce transmission shafts or pinions for the automotive industry in record time. These flexible machines can quickly adapt to a wide range of requirements, such as the creation of prototypes or small customised series. Thanks to CNC lathes, the safety of workers has improved. They can limit their interventions on the production line, even for repetitive tasks such as machining titanium parts.

The different types of CNC lathes

To help you choose the right CNC lathe, let's take a look at the different models available:
  • Inclined-bed and flat-bed lathes : the former offer better chip evacuation, while the latter are better suited to large parts.
  • Twin-spindle and multi-axis lathes : suitable for complex machining without intermediate dismantling.
  • Vertical lathes : used for large parts in heavy industry.

In the selection phase, take into account your production volume, the materials you use, the complexity of the parts to be machined and your budget.

Choosing a CNC lathe by business sector

Choosing a CNC lathe also depends on the requirements of your sector.

  • In aerospace, it guarantees ultra-fine tolerances and high reliability for critical parts such as engine components.
  • In the automotive industry, it excels in the mass production of mechanical parts such as drive shafts.
  • The energy and petrochemical industries need machines capable of machining large parts that can withstand extreme conditions. That's why a CNC lathe is still very effective for turbines or high-pressure valves.

And let's not forget the medical and watchmaking sectors. In these 2 sectors, the microscopic precision of a lathe makes it possible to create custom implants or complex watch mechanisms.

Choosing a used CNC lathe

Buying a used CNC lathe is an excellent strategy for optimising your costs. At SAMO, each machine is carefully inspected before being put back on the market. We offer you well-known brands such as Nakamura, Mori Seiki or Tornos at competitive prices. Consult SAMO's catalogue today and find the machine that meets your needs.
