When choosing a CNC lathe, it is fundamental to analyse several technical aspects. Below are some of
the most relevant criteria to consider when choosing a CNC lathe:
There are flatbed and slant bed lathes on the market. Slant bed lathes provide greater thermal stability as deformations caused by heat barely affect the accuracy of the machining.
There are machines fitted with linear guides and with prismatic guides. Prismatic guides provide more lasting precision and better tolerate the impacts that often happen in production environments. Even after considerable knocks, neither the guides nor the kinematic elements (headstocks, headstock bearings and engine support) are displaced, so that with a simple realignment the machine recovers its precision manufacturing capability. In contrast, linear guides suffer more from the effects of impacts.
There are two main methods for constructing prismatic guides: direct metal on metal contact or placing Turcite (a plastic material) between the guide and the carriage. Although the use of Turcite makes the manufacturing process more economical and easier, metal on metal contact provides a more robust solution with less wear and tear and sustained precision over time.
The current trend in CNC lathes is increasingly turning to milling, promoted by the development of cutting tools able to work at very high speeds. With high feed rates and cutting speeds and without the need for considerable pass depths, efficient smoothing can be executed, an ideal strategy for machining on a CNC lathe.
The installation of roller bearings in the spindles is considerably more complex than installing angular contact bearings. In roller bearings, the preload is defined during assembly itself, which requires cleanroom assembly procedures with strict temperature control and high precision measurements (in the range of microns). Spindles with roller bearings, however, have several significant advantages compared to those with angular contact bearings.
The shortage and excessive costs of skilled labour have led the industry to seek effective automation solutions. Available alternatives include anthropomorphic robots and Gantry Loader systems. The Gantry Loader is a more attractive option than the anthropomorphic robot.
CNC lathes burst into the world of machine tools to achieve total precision in the manufacturing of all types of workpieces. Thanks to the digital control, it is possible to control key aspects such as the speed and depth of the pass, and the speed of the cut and rotation, thereby minimising the errors seen on manual machines. This automation offers a high degree of adaptability and allows complex pieces to be machined.
The type of CNC lathes to choose will depend on the technical characteristics of the production process and the type of parts being machined. CMZ responds to the needs of any company that needs to buy a powerful, precise and reliable CNC lathe. In our catalogue of CNC lathes you can view the detailed technical specifications of all our lathe series.
You will find machines with one turret in the TA and TD Z800-Z1350 Series, which are frequently appeal to precision machining companies all over . If you are looking for a machine suitable for machining longer workpieces, in our CNC lathes catalogue you will find the TD Z2200-Z3200 series with beds measuring more than 2 and 3 metres from chuck to tailstock. Companies looking to machine more complex components from bar will find the CNC lathe they need in the TT Series, our multi-turret machines that have exclusive features thanks to the movements of the X3 and Z3 axes.
The high degree of configurability and automation of our CNC lathes not only allows very complex workpieces to be produced, but also makes it possible to repeat the process without any type of deviation or errors.
In sectors in which every micron counts, working with precise and reliable machinery provides a guarantee. CNC lathes offer a degree of precision that would be inconceivable on other types of machines such as manual lathes.
Every second counts. With CNC lathes you invest less time in the machining process. Thanks to our applications department, reducing cycle times to produce more parts in the least amount of time is a reality which, furthermore, does not entail any loss of accuracy whatsoever.
Our CNC lathes catalogue also provides various automation solutions. Our range of Gantry Robot Loaders will help you reduce dead times when loading and unloading. There is a type of Gantry Robot Loader for every production process, and if there isn’t one, we can customise it.
The software that controls the lathe speeds up set up times. Thanks to our simple conversational programming system, it is easy and simple to use.
THE POWER OF A MANUFACTURER
We have been in the machine tool market for over 75 years. In an increasingly globalised and depersonalised world, we opt for the “homemade”, and we continue to maintain the essence of that small family business that began in 1945. Now, there are more than 450 of us involved in producing these lathes CNC.
We have over 40,000m2 of surface area at our customers’ service, production plants where we produce our CNC lathes with the aim of offering the customer a powerful and reliable product, avoiding the importation costs associated with machines made by other manufacturers outside of Europe. Our machines have an average life span of over 20 years.
