CNC equipment (especially CNC equipment using CNC devices) is an important equipment for realizing flexible automation and has been increasingly widely used in various industries. Compared with other processing equipment, CNC machine tools have the following characteristics.
1.CNC machine tools have strong adaptability
Adaptability, also known as flexibility, refers to the adaptability of CNC machine tools to changes in production objects. When products (production objects) are processed on CNC machine tools, only the input program of the CNC machine tools needs to be changed to adapt to the production needs of new products without changing the hardware of the mechanical and control parts, and the production process is completed automatically. This feature not only meets the current market competition needs of fast product updates, but also better solves the problem of automated production of single-piece, small-batch, and variable products. Strong adaptability is the most prominent advantage of CNC equipment and the main reason for the emergence and rapid development of CNC equipment.
2.CNC machine tools can achieve complex movements
Ordinary mechanical equipment is difficult or impossible to achieve the movement of curves or surfaces with a trajectory of more than three times, such as space surfaces such as propellers and turbine blades, while CNC equipment can achieve almost any trajectory movement and process any shape of space surfaces, which is suitable for the processing of complex and special-shaped parts.
3.CNC machine tools have high precision and stable quality
CNC machine tools work automatically according to a predetermined program. Generally, the working process does not require human intervention, which eliminates the errors caused by operators. When designing and manufacturing the main machine of the equipment, many measures are usually taken. Make the mechanical part of the CNC equipment reach a higher precision. The pulse equivalent (or resolution) of the CNC device can currently reach 0.01~0.0001mm. At the same time, higher precision can be obtained by real-time detection feedback correction or compensation. Therefore, CNC machine tools can obtain higher processing accuracy than the equipment itself, especially improve the consistency of the production of parts in the same batch, and make the product quality stable.
4.CNC machine tools have high productivity
CNC equipment is many times more productive than ordinary equipment. Especially for the processing of some complex parts, the productivity can be increased by dozens of times or even dozens of times. The reasons for the high productivity are:
(1) CNC equipment (such as CNC machine tools) can use a larger cutting amount, which effectively reduces the cutting time during processing;
(2) It has functions such as automatic speed change, automatic tool change and other auxiliary operation automation, and does not require inspection and measurement between processes, which greatly shortens the auxiliary time;
(3) CNC machining centers with centralized processes and multiple uses can almost complete all the processing of parts after one clamping, which can not only reduce clamping errors, but also reduce the turnover time of semi-finished products (including transportation, measurement, etc.), and the improvement of productivity is more obvious.
5.CNC machine tools can reduce labor intensity and improve working conditions
The work of CNC machine tools is completed automatically and continuously according to the pre-compiled processing program. In addition to inputting the processing program, operating the keyboard, loading and unloading the workpiece, performing intermediate measurements of key processes and watching the operation of the equipment, the operator does not need to perform heavy and repetitive manual operations, and the working conditions and labor intensity are greatly improved.
6.CNC machine tools are conducive to production management
The use of CNC machine tools can accurately calculate the working hours of product production and effectively simplify the management of inspection, fixtures and semi-finished products. CNC machine tools use standard code input of CNC information, which is conducive to connecting with computers to form a small batch production system controlled and managed by computers, realizing the automation of manufacturing and production management.
