We will talk to you, usually how to do the retrofit of the customer, some of the details, may be closer to reality than the official manual.
What Is Fanuc System Retrofit?
Simply put, it is in the original machine structure remains unchanged, the key components replaced or upgraded. Commonly, it is:
* Replacing old servo motors and drives with more efficient models;
* Upgrade the feedback system (such as encoders, detectors), so that positioning and speed control more accurate.
The effect of the modification is very intuitive: the machine responds faster, the machining accuracy is higher, and the failure rate is lower. The first thing many customers say after using the machine is: "This machine is ten years younger.”
Why Do Fanuc System Retrofit?
We have seen many factories where the machine itself is fine, but the system is dragging its feet. Common problems are:
* Maintenance costs are getting higher and higher: the old system does not move the alarm, repair once to stop half a day production line.
* Efficiency can not keep up: the old controller processing speed is slow, processing cycle time is long, a single goods to do down a day later than others.
* Parts out: some of the old Fanuc parts have been discontinued, bad can not find parts.
This time to do the retrofit is very cost-effective. Compared with buying a new machine tool, the cost can save more than half, but also to avoid long downtime.
How Do We Usually Retrofit?
Let's take a look at a common process that we follow:
1. Initial Assessment
To the scene of the machine's controller, servo motors, drives, power supply, feedback devices are over, to see which can still be used, which must be replaced. Like a machine to do a "physical examination”.
2. Give a solution
For example, you do is a mold processing, then we will focus on speed and accuracy; if it is car parts, then focus on stability and durability. The program will list clearly: what to change, what to keep, and how long the duration.
3. Start upgrading
Put the new Fanuc controller on, replace the old drive and servo, and add new encoders if necessary. This part of the most difficult work, because we have to ensure that the new and old systems can be compatible, can not be installed on the run.
4. Debugging and testing
After installation, it must be repeatedly debugged to test the positioning accuracy, machining speed, load conditions, to ensure that each link is stable. After tuning the machine, you can immediately feel the "smoothness” of the machine.
5. Delivery and training
Finally, we teach the customer's operators how to use the new system and what is different from the old system. After all, the menu and operation logic will be different after the controller is changed, so it's good to get used to it in advance, so that you can use it smoothly later on.
A Small Case
A customer is making aerospace parts, the machine is quite new, but the system is outdated. The system is outdated. Orders are often delayed because the controller is jammed. We helped them to replace the Fanuc 30i controller and add a new servo drive. After the transformation, the machining cycle was shortened by 15%, and the number of alarms was obviously reduced. The customer later laughed and said: "Originally I thought I had to replace the new machine, but now I found that the old man is quite capable.”
Summarize
Fanuc system retrofit, to put it bluntly, is to give the machine tool to do "upgrade surgery”.
* Want to save money and efficiency → transformation is more cost-effective than buying a new machine.
* Want to extend the life of the equipment → new system can make the old machine tool to fight for a few years.
* Want to keep up with new technology → Fanuc's latest controller and drive can be compatible with the current process requirements.
We have a lot of experience in Fanuc system retrofit, servo drive upgrades, controller replacement, if you are thinking of giving the machine tool "change the heart”, you may want to find us
Songwei to talk about, may help you save a lot of money, but also to make the machine tool run faster and more stable.
