I've been putting this particular tnc635r review together because, let's be honest, staring at a flickering, blurry CRT screen on an old Heidenhain controller is a special type of torture for your eyes. In the event that you're still operating an older device tool, you understand precisely what I'm talking about. You're attempting to read heads or check a line of code, and you're fundamentally squinting through a green fog.
When my old monitor finally started pulling that "shrinking horizontal line" work before going presentation black, I had to locate a replacement quick. That's how We ended up with the TNC635R. It's designed specifically as a drop-in FLATSCREEN replacement for all those legendary Heidenhain TNC units—think the 135, 145, 150, 151, 155, and also the 2500 collection.
Why Also Bother Replacing the Screen?
You might wonder exactly why someone wouldn't simply scrap the entire handle system and retrofit the entire machine. Well, if you've checked the costs on a full CNC retrofit lately, you know it expenses a small lot of money. Plus, those older Heidenhain systems are tanks. They work. They're reliable. The only part that will really "ages" badly is the screen technology.
The TNC635R is essentially a bridge among the 1980s now. It takes that old analog indication and puts it onto a crisp, modern 12. 1-inch LCD. This might sound such as a small change, but in a busy shop environment, it's a substantial quality-of-life upgrade.
First Impressions and Build Quality
When the unit came, I was pleasantly amazed by how strong it felt. Occasionally these "replacement" components feel like inexpensive plastic knock-offs, but this one offers some weight to it. The metal casing feels long lasting enough to deal with the vibrations plus general chaos of a machine shop.
The front -panel is clean, as well as the mounting holes lined up perfectly with the particular original housing. That's always the greatest fear with these things—that you're going to have got to get away the drill and start hacking away at your control cabinet just in order to make a "compatible" part fit. Thankfully, that wasn't the case here.
The Installation Process
I'm a huge fan of issues that are in fact "plug and play, " even though that term is generally a lie. Along with the TNC635R, it had been actually pretty close to the truth.
Tearing Down the particular Old Unit
Obtaining the old CRT out is the particular hardest part, mostly because those things are weighty and usually protected in twenty years of shop dirt. Once I removed out the outdated monitor and the particular high-voltage transformer (which you won't require anymore, thank goodness), I had fashioned plenty of room to work.
Wiring Up
The TNC635R comes with the specific connectors needed regarding the Heidenhain user interface. I didn't possess to strip wires or guess which usually signal was which usually. I just connected the existing video cable connection into the back of the new LCD, linked the power, and I was basically done. It's a 15-to-20-minute work if you've got a screwdriver plus a steady hand.
One point I absolutely appreciated had been the insufficient "fiddling. " Usually, along with LCD conversions, you're spending an hour adjusting the horizontal plus vertical hold just to get the image centered. This particular unit seemed to auto-scale the signal pretty well right out of the box.
Screen Performance: CRT vs. LCD
This is where the tnc635r review gets in order to the great stuff. The difference in clarity is day and night.
Within the outdated CRT, the text was often a little soft. When the shop has been bright, the brilliance was brutal. The TNC635R uses an industrial-grade LCD screen that is significantly brighter than the original screen actually was. The contrast is sharp—black is usually actually black, plus the text (whether it's green or even amber depending on your setup) springs perfectly.
Seeing Angles
In a workshop, you're rarely standing perfectly centered in front side of the screen. You're leaning over to look at the workpiece, reaching intended for a tool, or even checking the readout from the side. Inexpensive LCDs wash away in case you aren't looking at them head-on. This unit offers surprisingly good seeing angles. I possibly could remain a few feet to the side and still clearly read the axis positions without the particular colors inverting or the screen becoming a gray clutter.
Refresh Rate and Lag
I was a bit worried about input lag. Sometimes these signal converters consider a millisecond too much time to process the old analog data, producing the numbers appear "jittery" when they're changing fast. We didn't notice any of that here. Once the machine is homing or running a fast program, the particular numbers on the particular screen continue without having trailing or ghosting.
Long-Term Reliability in the Store
I've been using this setup for some time now, and it hasn't skipped a beat. One associated with the best side effects of switching to the TNC635R is that this generates almost no high temperature. Those old CRTs used to get hot enough in order to cook an ovum on, which isn't great for the longevity of the other electronics within the control cupboard.
The LCD stays cool, and because it's a sealed unit, I'm not as worried about coolant mist or great dust getting in the sensitive parts of the display. It's also much even more resistant to vibration. If you're performing heavy milling, the old CRT would sometimes "wobble" or perspective. The LCD will be rock solid.
Is It Worth the Price?
Let's talk money. You can find common LCD panels intended for cheaper on specific auction sites, but then you need to deal with finding a compatible video converter board, mounting brackets, and power adapters. To get a hobbyist with infinite time, that's fine. For the business in which the machine needs to end up being making chips in order to make money, it's a bad shift.
The TNC635R isn't the least expensive component in the particular world, but it saves hours of frustration. You're paying for the fact that somebody already did the particular engineering to make it fit a very particular, very old device. In my opinion, that's worth the premium. It's less expensive than a "genuine" replacement through the original manufacturer (if they even still stock them), and it's the hell of the lot much better than buying an used CRT that's already upon its last legs.
Conclusions
Wrapping up this tnc635r review , I'd say if you're running an old Heidenhain mill and your screen will be starting to go, don't wait until it dies completely. It's one of those upgrades that makes you wonder why you waited such a long time to do it.
It's easy to set up, the display quality is lightyears ahead of the original, plus it keeps your old reliable machine in the video game for another decade. It's not a flashy upgrade, but it's the practical one that makes every day in the shop just a little bit easier on your own eyes.
Pros: * True drop-in replacement; no adjustments needed. * Superb brightness and comparison compared to CRT. * Low power consumption and very little heat. * Solid quality for industrial environments.
Cons: * More expensive than the DIY monitor hack. * The display screen might actually be too bright at very first (though you can adjust it).
When you're for the wall, just do it. Your eyes can thank you, as well as your machine will appear like it in fact belongs nowadays.
