What are the new development trends in the design of inclined bed CNC lathes?

In people’s minds, inclined bed CNC lathes are large machine tools that occupy a large area and are heavy in tonnage. Although it is difficult to change this bulky image for a while, some companies in the industry have begun to innovate in the design of inclined bed CNC lathes. The bed structure adopts a more lightweight design, which has also led to new trends in machining carbon fiber  tool design.

If you want to carry out a lightweight design for a slant bed CNC lathe, you must first clarify what the lightweight indicators are. In layman’s terms, it is to reduce the material consumption and energy consumption during the manufacturing of the bed and reduce the weight of the bed as much as possible under the condition that the static stiffness of the machine tool itself is met.
So, how can designers of inclined bed CNC lathes achieve the goal of lightweight design. First of all, it is necessary to establish a physical model of the machine bed design, find a better structural optimization path based on this model, and further optimize the design parameters. At the same time, it is necessary to combine the investment casting process requirements and impose corresponding process constraints.

Secondly, designers need to further optimize the bed size of the inclined bed CNC lathe. Specifically, they use finite element software to obtain a series of performance parameters and data, and obtain the corresponding functional relationships through the performance parameters and data. , and then combined with the various characteristics of the bed to obtain the final optimized size of the bed.

After the optimization design of the inclined bed CNC lathe is completed, it does not mean the end. The designers also need to analyze and compare the static stiffness and equipment performance before and after the design. If the weight of the optimized bed can be reduced by a percentage compared with the weight before optimization, More than seven, and the static stiffness remains unchanged, which shows that the design has achieved the predetermined goal.

Inclined bed CNC lathes are suitable for processing various shafts, discs and batch parts with complex shapes, and are more suitable for the production of large-volume parts with high accuracy and dimensional consistency requirements. The longitudinal and transverse motion axes of the machine tool are driven by servo motors, precision ball screw pairs, high-rigidity precision composite bearing transmission, and a semi-closed-loop control system with pulse encoder position detection feedback. The guide rail pair adopts the popular high-frequency quenching (hard rail) and “plastic pasting” process. Each movement axis has fast response, high precision and long life.
