Development Trend of CNC Lathes

Since the beginning of the 21st century, with the continuous development of CNC technology and the expansion of application fields, IT has played an increasingly important role in the development of some important industries (IT, automobiles, light industry, medical, etc.) that support the national economy and people's livelihood, because the digitization of equipment required by these industries has become a major trend in modern development. Generally speaking, CNC lathes show the following three trends:

High speed, high precision

High speed and high precision are the eternal goals of lathe development. With the rapid development of science and technology, the replacement rate of mechanical and electrical products is accelerating, and the requirements for precision and surface quality of parts processing are getting higher and higher. In order to meet this complex and ever-changing market demand, current lathes are developing in the direction of high-speed cutting, dry cutting and quasi-dry cutting, and the processing accuracy is constantly improving. On the other hand, the successful application of electric spindles and linear motors, the market for lathe functional components such as ceramic ball bearings, high-precision hollow internal cooling and the powerful cooling of low-temperature high-speed ball screw pairs and linear guide pairs with ball retainers have also created conditions for the development of lathes towards high speed and high precision.CNC lathes use electric spindles, eliminating belts, pulleys, gears, etc., which greatly reduces the inertia moment of the main drive, improves the dynamic response speed and working accuracy of the spindle, and completely solves the problem of vibration and noise of belts, belts and other transmissions when the spindle is running at high speed. The electric spindle structure can make the spindle speed reach more than 10000r/min.

Linear motors have fast driving speed, good acceleration and deceleration characteristics, and excellent response characteristics and following accuracy. Using a linear motor as the servo drive eliminates the intermediate transmission link of the ball screw and the transmission gap (including backlash). The motion inertia is small, the system stiffness is good, and the servo accuracy can be accurately positioned at high speed, thereby greatly improving the servo accuracy.

The linear rolling guide pair, due to its zero directional clearance and very small rolling friction, has small wear and negligible heat, has very good thermal stability, and improves the positioning accuracy and repeated positioning accuracy of the entire process. By applying linear motors and linear rolling guide pairs, the rapid movement speed of the lathe can be increased from 10 to 20m/mim to 60 to 80m/min, and up to 120m/min.

High reliability

The reliability of CNC lathes is an important indicator of product quality.CNC latheWhether it can exert its high performance, high precision, high efficiency, and obtain good benefits depends crucially on its reliability.

CNC lathe design CAD, modular structure design

With the popularization of computer applications and the development of software technology, CAD technology has been widely developed. CAD can not only replace tedious manual drawing work, but more importantly, it can select design plans and analyze, calculate, predict and optimize the static and dynamic characteristics of large machines, and can perform dynamic simulation of the working parts of the machine. On the basis of modularity, three-dimensional geometric models and realistic colors of the products can be seen during the design stage. The use of CAD can also greatly improve work efficiency and improve the success rate of design, thereby shortening the trial production cycle, reducing design costs, and improving market competitiveness.
