Development Trend of Full Function CNC Lathe

CNC technology which applied in CNC lathe and CNC lathe machine equipment is an important basis for industrial modernization in various countries. CNC technology which used in the production has been more than 20 years of history, full-function CNC lathes has a great significance on the field of numerical control development. We should seize the opportunity to continuously develop innovative full - function CNC lathes.

1.Iintelligent control

With the development of artificial intelligence technology, in order to meet the flexible manufacturing and manufacturing automation development needs, the degree of full-featured CNC lathe intelligent is increasing constantly.

(1) The process of adaptive control technology: by monitoring the processing of the cutting force, spindle and feed motor power, current, voltage and other information, the use of traditional or modern algorithm to identify the tool to identify the force, wear, damage and state of machine tool processing to improve the processing accuracy, reduce the processing of surface roughness and improve the safety of equipment operation;

(2) intelligent fault self-diagnosis and self-repair technology: According to the existing fault information, the application of modern intelligent methods to achieve rapid and accurate fault location;

(3) intelligent AC servo drive: can automatically identify the load, and automatically adjust the parameters of the intelligent servo system, including intelligent spindle AC drive and intelligent feed servo device;

(4) The intelligent optimization and selection of processing parameters: the experience of the process experts or technicians, parts of the general and special laws, with modern intelligent methods, based on the expert system or the "processing parameters of intelligent optimization and selector" .Improve the programming efficiency and processing technology level, shorten the purpose of production preparation time;

(5) Inelligent fault playback and fault simulation technology: a complete record of the system of various information on the NC machine tool for the occurrence of various errors and accidents playback and simulation, to determine the cause of the error, find a solution to the problem and accumulate production experience;

2. High Speed Production

With the rapid development of automobile, national defense, aviation, aerospace and other new materials such as aluminum alloy, the demand for high-speed machining of full-function CNC lathe is getting higher and higher.

(1) Tool change speed: the current foreign advanced machining center tool exchange time is generally about 1s, the higher could reach to 0.5s.

(2) Feedrate: When the resolution is 0.01μm, the maximum feed rate is 240m / min and the precise machining of complex surface can be obtained.

(3) Spindle speed: lathe with spindle (built-in spindle motor), the maximum spindle speed of 200000r / min;

(4) The speed of operation: the operation speed is greatly improved, so that when the resolution of 0.1μm, 0.01μm can still get up to 24 ~ 240m / min feed rate.
