What is the difference between CNC milling machines and machining centers? In fact, this problem is not only very confusing for laymen, but also confusing for many people in the industry.
Simply put, the
Machining Center is an upgraded version of the CNC milling machine, and the two kinds of processing equipment are mainly different in the following three aspects:
The biggest difference is whether there is a knife library
Ordinary CNC milling machines also have a numerical control operating system (such as Japan Fanuc, Germany Siemens, China Central or Guangshu, etc.), also has three feed shafts and a rotating spindle, their processing mode geometry is exactly the same, but also basically can achieve the same processing capacity.
And their biggest difference is to see whether the equipment with a tool library, the machining center is actually a CNC milling machine with a tool library, the machining center can achieve a clamping and complete the work of multiple processing processes, such as milling, drilling, tapping, etc., because it can realize the automatic change of the tool, and in the continuous processing process of multiple processes, The operator does not need manual intervention, as long as the program is prepared, the tool and the corresponding parameters can be configured. Numerical control milling machine is not, numerical control milling machine can also achieve a clamping process of multiple processes, the difference is that in the process of conversion, must manually change the tool, so the processing process is discontinuous, is a number of degrees of intermittent execution, such processing whether in processing quality, or processing efficiency, are slightly inferior to the processing center.
Fully protected or not
In fact, this is not absolute for a lot of equipment, many CNC milling machines are gradually beginning to make a fully protected processing mode, of course, there are many old CNC milling machines using still open processing methods, or semi-protected processing methods, which to a certain extent and the current machining center still has a certain difference, Of course this distinction is not absolute (again).
In fact, this and the development process of equipment has a great relationship, in the primary stage of CNC processing equipment, in fact, many manufacturers do not pay much attention to the appearance of design and safety protection, basically stay in the function of the appeal, so many CNC milling machines have been made into an open form, or do a good point is semi-open form, Although this CNC milling machine does not have too many defects in function, there are still great shortcomings in the processing safety and processing environment.
For example, the high-temperature iron filings generated by processing will splash onto the human body, causing harm to the human body, the coolant used to cool the tool in the processing process will also splash onto the operator, dirty the operator's clothes, etc., so although the progress of the research and development of production equipment, especially the invasion of foreign high-end equipment, the design and manufacturing of China's processing equipment is also moving toward a more humane, more beautiful, On a more artistic path.
This is a process, any progress needs a process, product technology, product art, is the future of the unified requirements for industrial products, but also the only way for the future development of industrial products.
Whether it has an automatic chip extractor
This criterion is the same as the previous one, is not an absolute criterion, but also based on the process of processing equipment development to judge a mobile standard, the reason is also because of the previous equipment in the development of some knowledge of the function of the trade-off caused by many new CNC milling machines, full protection and automatic chip removal device are basically standard. And machining center is not much different.
But for those old CNC milling machines, this evaluation standard is still useful, after all, a equipment that does not even do a good job of protection, is in any case, do not dare to ask for what automatic chip removal, in fact, now the machinery industry practitioners, should thank this era, is this era to provide the liberation of our hands technology and ability, Let us more easily and efficiently engage in our own work, and with the comprehensive development of industry 4.0, this liberation of the labor force is also speeding up, and even produce a lot of labor or labor methods of elimination, we must always be prepared.
