I'm Casey Bartholomew and with me today is Scott Spangler, president of Roland America.

我是凱西-巴塞洛繆，今天和我在一起的是羅蘭美國公司的總裁斯科特-斯潘格勒。

Now in this video we're going to be talking about one of the most popular linear guides that you'll see today and that's the profiled rail guide.

在本視頻中，我們將討論當今最流行的直線導軌之一，即異型導軌。

Now Scott, can you give us a little bit of background on how this guide came about and maybe some of the applications that it's generally used in?

現在，斯科特，你能給我們介紹一下該指南的背景，以及它的一些一般應用嗎？

Sure, so the profile rail was patented back in 1932.

當然，輪廓導軌早在 1932 年就獲得了專利。

It wasn't until the 70s and 80s when they were able to make it and mass-produce this product and it was made for the machine tool industry.

直到上世紀七八十年代，他們才能夠製造和批量生產這種產品，而且是為機床行業製造的。

Very high accuracy, sub-micron, stiff, high precision type of applications.

精度非常高、亞微米級、堅硬、高精度類型的應用。

Okay, so it started out being designed for machine tools but where do we usually see it today?

好吧，它一開始是為機床設計的，但如今我們通常在哪裡看到它呢？

Is that still the case or is it kind of proliferated across different automation?

現在還是這樣嗎，還是在不同的自動化系統中擴散？

It became very popular and people started using it in other applications and you probably see it when you're doing applications in assembly.

它變得非常流行，人們開始在其他應用程序中使用它。

Yeah, all the time.

是啊，一直都是。

All the time.

一直都是

People are using it in applications it really wasn't designed to do because it's not compliant whatsoever.

人們把它用在設計上並不適合的應用中，因為它根本不符合標準。

Right, so I guess nowadays it's being pulled into more lower accuracy applications and it's actually kind of hindering or over-constraining the system as a whole, right?

是的，所以我猜如今它被拉入了更多低精度的應用中，這實際上有點妨礙或過度限制了整個系統，對嗎？

Right, if you're shoving Snickers bars into a box, you know, you don't need sub-micron level accuracy.

沒錯，如果你要把士力架塞進盒子裡，你知道，你並不需要亞微米級的精度。

You need something that you can put together in your machine quickly.

您需要的是能在機器上快速組裝起來的東西。

You don't have to worry about machining the bases and it needs to be compliant.

您不必擔心底座的加工問題，而且它必須符合要求。

This is not compliant.

這不符合規定。

Right, so now let's talk about something that is compliant and something that's right in the wheelhouse of applications such as those.

好了，現在讓我們來談談符合標準的東西，也是這些應用程序的理想之選。

Good, let's talk about the compact rail.

很好，讓我們來談談緊湊型導軌。

Yeah, we got the compact rail right here.

是的，我們這裡有緊湊型軌道。

So where's the accuracy cutoff?

那麼精確度的分界線在哪裡？

Where are you going to move from a high-precision product like profiled rail into a more medium precision compliant product like compact rail?

從異型導軌等高精度產品到緊湊型導軌等更符合中等精度要求的產品，您打算從哪裡轉移？

So positioning accuracy at about 200 microns.

是以定位精度約為 200 微米。

If you need sub 200 microns, stay with the profile rail because it is a more accurate guide.

如果您需要 200 微米以下的精度，請繼續使用輪廓導軌，因為它能提供更精確的指導。

But this also has ground raceways, so it's a precision guide itself, but typically used in more pick-and-place assembly type applications and those would be over 200 micron level.

但這種導軌也有地面滾道，所以它本身也是一種精密導軌，但通常用於拾取和貼裝類型的應用，這些應用的精度會超過 200 微米。

Okay, and I'm sure there's cost savings that come along with specking a product that's more compliant and it doesn't require as a precise mounting surface.

好吧，我相信，如果產品的規格更符合要求，而且不需要精確的安裝表面，肯定能節省成本。

Right, you don't need to machine the base plate, you don't need to machine any of the mounting surfaces, you just drill holes and basically bolt it down.

沒錯，你不需要加工底板，也不需要加工任何安裝表面，只需鑽孔，然後用螺栓固定即可。

It can misalign up to about four millimeters, and I think this is what this demo shows.

它最多可以錯位四毫米，我想這就是這個演示所顯示的。

Yeah, and let's take a look at what happens when you introduce misalignment into these two different types of linear guides.

是的，讓我們來看看在這兩種不同類型的直線導軌中引入偏差會發生什麼。

Here on the right we have profiled rail that's been misaligned in both the height directions as well as the parallelism directions.

右邊是在高度和平行度方向上都有偏差的異型軌道。

You can see that this rail on the left has been shimmed off of the base plate four millimeters, and these rails have also been misaligned in parallelism of four millimeters.

可以看到，左邊的導軌偏離底板 4 毫米，這些導軌的平行度也有 4 毫米的偏差。

So with this type of misalignment you can see that this profile guide is really difficult to move, and that's also going to lead to premature bearing failure, increased wear, and an overall more, I guess, poorer performing system than you're going to get with something like profiled rail.

是以，在這種錯位情況下，你可以看到這種型材導軌很難移動，這也會導致軸承過早失效、磨損加劇，以及整體性能（我猜是）比型材導軌更差的系統。

Here on the left we have our compact rail, which has been same misalignment, four millimeters, so it's been height misaligned and pitch misaligned.

左側是我們的緊湊型導軌，它也有同樣的偏差，4 毫米，是以高度和間距都有偏差。

But let's take a look at the difference in the motion that you get from these linear guides.

不過，讓我們來看看這些直線導軌的運動差別。

See, it's nice and smooth.

看，它又光滑又漂亮。

Nice, smooth, easy, accurate, repeatable.

漂亮、流暢、簡單、準確、可重複。

That's what you're going to get with profiled rail that's been misaligned compared to, that's what you're going to get with compact rail compared to profiled rail when it's misaligned.

與錯位的異型鋼軌相比，緊湊型鋼軌與錯位的異型鋼軌相比，就會出現這種情況。

So this is a good example to show the benefits of going with a more compliant linear guide versus a more precise but restrictive linear guide when it comes to mounting.

是以，這是一個很好的例子，說明在安裝時，使用更順從的直線導軌比使用更精確但限制性更強的直線導軌更有優勢。

It's all about using the right guide for the right job.

關鍵在於使用正確的指南來完成正確的工作。

Right.
