Development trend of CNC lathes

Since the beginning of the 21st century, with the continuous development of CNC technology and the expansion of its application fields, it has played an increasingly important role in the development of some important industries of national economy and people's livelihood (IT, automobiles, light industry, medical treatment, etc.), because the digitization of equipment required by these industries has become a major trend in modern development. Overall, CNC lathes exhibit the following three development trends:
High speed and precision
High speed and precision are the eternal goals of machine tool development. With the rapid development of science and technology, the speed of upgrading mechanical and electrical products is accelerating, and the requirements for the accuracy and surface quality of parts processing are also becoming higher and higher. To meet the needs of this complex and ever-changing market, machine tools are currently developing towards high-speed cutting, dry cutting, and quasi dry cutting, and the machining accuracy is also constantly improving. On the other hand, the successful application of electric spindles and linear motors, as well as the launch of functional components such as ceramic ball bearings, high-precision large lead hollow internal cooling, and low-temperature high-speed ball screw pairs with ball nut strong cooling, as well as linear guide pairs with ball retainers, have also created conditions for the development of machine tools towards high-speed and precision.
The CNC lathe adopts an electric spindle, eliminating links such as belts, pulleys, and gears, greatly reducing the rotational inertia of the main drive, improving the dynamic response speed and working accuracy of the spindle, and thoroughly solving the vibration and noise problems of belts, pulleys, and other transmissions during high-speed operation of the spindle. The use of an electric spindle structure can achieve a spindle speed of over 10000r/min.
The linear motor has high driving speed, good acceleration and deceleration characteristics, superior response characteristics, and tracking accuracy. Using a linear motor as a servo drive eliminates the intermediate transmission link of the ball screw, eliminates the transmission clearance (including reverse clearance), has small motion inertia, good system rigidity, and can accurately position at high speeds, greatly improving servo accuracy.
The linear rolling guide pair, due to its zero clearance and very small rolling friction in all directions, has low wear and negligible heat generation, and has excellent thermal stability, improving the positioning accuracy and repeated positioning accuracy throughout the entire process. Through the application of linear motors and linear rolling guide pairs, the fast moving speed of the machine tool can be increased from 10-20m/min to 60-80m/min, with a maximum of 120m/min.
high reliability
The reliability of CNC machine tools is a key indicator of product quality. Whether CNC machine tools can achieve their high performance, high precision, and high efficiency, and achieve good benefits, depends crucially on their reliability.
CAD based and modular structural design for CNC lathes
With the popularization of computer applications and the development of software technology, CAD technology has been widely developed. CAD can not only replace manual labor to complete tedious drawing work, but more importantly, it can select design schemes, analyze, calculate, predict, and optimize the static and dynamic characteristics of large equipment. It can also perform dynamic simulation of various working components of the entire machine. On the basis of modularization, the 3D geometric modeling and realistic color of the product can be seen at the design stage. By using CAD, work efficiency can be greatly improved, the first success rate of design can be improved, thereby shortening the trial production cycle, reducing design costs, and improving market competitiveness.
