Defining Precision in Everyday Terms

Posted 3/6/2017

Aligning a machine is a complex, time-consuming process that absorbs hundreds of man-hours and thousands and thousands of dollars in downtime. For this reason, machine tools are usually aligned only when the parts they produce decline in quality. But how important is precision in machine tooling anyway?


While the factory specifications for every machine tool vary, for many machines, alignment within 4 microns is the edge of acceptable. But when you're talking about a micron, how small a measurement is it really?


A micron is one millionth of a meter. Measurements that precise are easy to talk about but difficult to comprehend. For an easier comparison, there are 25,400 microns in a single inch. In fact, anything smaller than 40 microns isn't even visible to the naked eye.


For example, the average human hair is around 40 to 50 microns in diameter. If you were to take the diameter of a single human hair and divide it into tenths, one of those tenths would be 4 microns--the edge of acceptability for proper machine tool alignment.


With numbers that small and precise, how could anyone even guess on machine tool alignment? Experienced workmen with wrenches and jack bolts can align a machine manually and get close whenever production schedules allow time for it. But manual leveling and alignment often require a manufacturer to characterize a machine's errors because it just doesn't make sense to spend so much time and money on exact precision.


But what if you could keep your machine tool aligned within a micron of its factory specifications all the time?


Instead of a man with a wrench, you can use a mouse and a computer to align your machine, using the Tru-Lign System. You can bring all the pads of your machine tool into balance with the click of a mouse button, and what would have taken weeks or maybe even months with a wrench now takes only hours.


With a single mouse click, you can inject oil the size of a grain of sand into each Tru-Lign pad, adjusting and tweaking as you go, until your machine is back in line with its factory specifications. And you don't even have to crawl on the floor to do it.


Save money on your budgets. Keep workers safe. Not only that, but with the Tru-Lign system, you can even document your changes for an accurate record of alignments performed.


Manual alignment with a wrench can get close enough to factory specifications, but if you want to guarantee that the parts your machine tool is producing are the best they can be, you need to stay as close to your specs as possible. The Tru-Lign system can make precision alignment as simple as the click of a mouse.
