CNC lathes and turning centers are automatic machine tools with high precision and high efficiency. Equipped with a multi-station turret or a power turret, the machine tool has a wide range of processing performance and can process linear cylinders, oblique cylinders, arcs, and various threads, grooves, worms, and other complex workpieces, with linear interpolation, arc Interpolate various compensation functions, and play a good economical effect in the mass production of complex parts. Reasonable selection of CNC lathes should follow the following principles:

1. Preliminary preparation

Determine the process requirements of typical parts and the batch of workpieces to be processed, formulate the functions that CNC lathes should have to make preparations in advance, and the prerequisites for rational selection of CNC lathes to meet the process requirements of typical parts. According to the accuracy requirements, that is, the dimensional accuracy, positioning accuracy, and surface roughness of the workpiece, the control accuracy of the CNC lathe is selected. Choose according to the reliability, which is the guarantee of improving product quality and production efficiency. The reliability of CNC machine tools means that when the machine tool performs its functions under specified conditions, it runs stably for a long time without failure. That is, the mean time between failures is long, even if a failure occurs, it can be recovered in a short time and put into use again. Choose a machine tool with a reasonable structure, well-manufactured, and mass-produced. Generally, the more users, the higher the reliability of the CNC system.

2. Purchase machine tool accessories and tools

Machine tool accessories, spare parts, and their supply capacity and tools are very important for CNC machine tools and large gantry machining centers that have been put into production. When choosing a machine tool, careful consideration should be given to the compatibility of tools and accessories.

3. Compatibility of cutting oil

The compatibility of cutting oil directly affects the processing effect of CNC lathes. Cutting oil with excellent performance can effectively protect the tool, improve the machining accuracy of the lathe, greatly improve the processing efficiency, and avoid the occurrence of rusting and yellowing of the lathe machine and the deterioration of the processing workshop environment. question.

4. According to the performance-price ratio to choose

Make sure that the functions and precision are not idle or wasted, and do not choose functions that are not related to your needs.

5. Pay attention to the identity of the control system

Machining center manufacturers generally choose products from the same manufacturer, at least the control system of the same manufacturer, which brings great convenience to maintenance work. Teaching units, due to the need for students to be well-informed, choose different systems, and it is a wise choice to be equipped with various simulation software.

6. Protection of machine tools

When required, the machine tool can be equipped with fully enclosed or semi-enclosed guards and automatic chip removal devices.

When choosing CNC milling machine lathes and machining centers, the above principles should be comprehensively considered.
