How Critical Is the CNC System?
Simply put, the CNC system is the brain of the entire machine tool. It directly affects:
* The speed and accuracy of parts processing.
* You want to the future on the robot or other automation systems, good or bad connection.
* Problems, the maintenance of hemp is not troublesome, easy to change parts is not easy.
Choose the wrong system, light is slow, heavy is to change a spare part can not find a match, the late toss. M80 and 828D are common mainstream models on the market, but they are completely different styles, with the feeling of quite a lot of difference.
M80: Mitsubishi Home to a New Generation of the Main
M80 is used by Mitsubishi to replace the old M70 new model, fast, simple interface, many Asian machine tools use this.
Use down the most intuitive several features:
* Fast processing speed, especially suitable for milling, mill-turn composite such high-efficiency scenarios.
* 15-inch touch screen, menu logic is clear, get started quite quickly.
* Comes with Mitsubishi PLC, and Mitsubishi motors, drives, smooth communication, wiring is also a waste of time.
* Compact module design, does not take up space in the cabinet.
Many of our customers use it to install on Riga, CNC lathe, drilling and tapping center, the overall package is quite mature.
828D: Siemens Does It Differently
828D is more like a representative of the "graphic school”, which is about user-friendly operation, intuitive program, and suitable for precision machining.
These are the highlights of the actual experience:
* ShopMill and ShopTurn graphics are easy to understand, and you don't need much G-code experience to get started.
* SinuTrain simulation software is included, so programs can be written offline and imported directly.
* The communication is PROFINET, which is convenient to connect to the factory network.
* PLC is Siemens S7 series, with strong logic processing capability.
* The system is highly stable, anti-interference is good, and can run steadily even in the workshop environment.
The scenarios we have seen on the side of our European customers are mostly for high precision parts processing, such as in the automotive and aerospace fields.

Supporting Compatibility, It Is Important to Choose the Right Brand
Simply put: if you originally use Mitsubishi drives and motors, then prioritize the M80; if you originally use a Siemens system, then lean towards the 828D.
Don't change platforms just to catch up with the new ones, for that will change too many things and cause trouble instead.
Who Has a Better Operation and Maintenance Experience?
The M80 gives people a feeling of "simplicity and cleanliness”:
The touch interface is quick to respond and the wiring is clear; it is also easy to back up the parameters, and the USB flash drive and SD card can be used. In addition, Mitsubishi's own maintenance tools, repair and check the efficiency of the problem is quite high.
The 828D is more of a "graphical logic school”:
Ideal for factory environments where there are many novices and training cycles are short. The alarm analysis system is well done, well documented, and multi-language support is in place. Siemens also provides online training resources, so it's not difficult to find information.

At Songwei, we supply both systems, drivers, motors, operating panels and other related parts, and we can also provide testing services to test them before shipment, so that you don't have to install them and then have problems.
Two Real Cases to Share with You
Case 1: Customer upgraded M70 to M80
A customer from Zhejiang wanted to improve machining efficiency, we provided a full set of M80 controllers, assisted in transferring parameters and ladder diagrams, and the degree of machining was significantly faster after installation, and the failure rate was also reduced.
Case 2: 828D Alarm Problem Handling
A German customer's machine jumped the axis drive alarm, and he checked it himself for several days without fixing it. We sent the driver back for testing and located the power module fault within 3 days, and normal operation was resumed after repair.
What Is the Best Choice?
The M80 is better for you if:
* You have a Mitsubishi system.
* You want high speed, fewer failures, and less complicated operation.
* You like the combination of touch screen + CC-Link communication.
The 828D is better for you if:
* You use European machines.
* Graphical programming is more friendly to you.
* You're using Siemens networks and systems.
Not Sure? Just Ask Songwei
We are experienced in Fanuc, Mitsubishi and Siemens CNC systems and can help you:
* Determine controller suitability.
* Provide original or refurbished parts (with warranty).
* Tested before shipment, directly on the machine.
* Repair drives, motors, motherboards, and other components.
