What is the difference between an ordinary lathe and a CNC lathe drive system?
Spindle drive system: 1, CNC machine tool spindle drive system is stepless speed regulation. 2, ordinary machine is to use speed gear to change the speed. Feed system of the transmission system: 1, the general machine is used in the way of hand feed. 2, CNC machine feed mode is the use of servo motor
Ordinary machine tool spindle drive relative to the CNC machine tools to be complex, need v-belt, gear complex transmission ratio to achieve the desired speed, noise, precision. And CNC are mostly variable frequency motor, adjust the speed. The advantages of noise is small vibration accuracy is relatively high, low energy consumption and reduce the number of complex lubrication system maintenance simple and convenient
First, the difference between CNC machine tools and general machine tools CNC machine parts of the processing process is strictly in accordance with the processing procedures specified by the parameters and actions. It is a high-performance automatic or semi-automatic machine tools, compared with ordinary machine tools, with the following obvious features: 1, suitable for complex shaped parts processing CNC machine tools can be completed difficult to complete or simply can not process the processing of complex parts, In the aerospace, shipbuilding, mold and other processing industry has been widely used. 2, high precision machining 3, stable and reliable processing to achieve computer control, excluding human error, parts of the processing of good consistency, stable and reliable quality. 4, high flexibility processing object changes, generally only need to change the NC program, reflecting the good adaptability, can greatly save production preparation time. In the CNC machine tools, based on the composition can be more flexible automated manufacturing system-FMS. 5, high productivity CNC machine tool itself, high precision, rigidity, can choose a favorable amount of processing, high productivity, generally 3 to 5 times the normal machine, for some complex parts processing, production efficiency can be increased by ten times Several times. 6, good working conditions, a high degree of automation of the machine, the operator labor intensity greatly reduced, the working environment is better. 7, is conducive to the management of modern CNC machine tools conducive to the development of computer control and management of production, in order to achieve the production process automation to create the conditions
