O.K., the world is not what it seems to be. Light is heavy.
(It has mass. Just ask Einstein.) Gravity distorts time.
Time is not a constant; it is relative to the observer.
(Ever been to an opera? Remember the last time you were
put on hold?) So…where do other so-called precision
actuator manufacturers get off by merely specifying THEORETICAL
straightness and flatness? Come on! You deserve better.
|
|
First there was Avogadro's Number: 6.02214199 x 10E23 molecules/mole.
Then came Planck's Constant: 6.62618 x10E-34 J's. Now there's
TruTrack Coefficient: 0.0002 inch per inch.
Just how good is this? When a TruTrack actuator leaves the
Tol-O-Matic production facility, variation in the flatness
AND straightness is validated to be less than 0.0002 inches
per inch of travel. You can count on TruTrack to meet your
most demanding application.

Line
of Motion (LOM) shouldn't run like a Line of Locomotive
(LOL). And we mean LOL! How can you control your load without
knowing actual flatness and straightness?
|
|
The
desired path of the LOM is a perfectly straight line between
the ends-of-stroke. This desired path becomes the reference
datum. Any deviation (in the Zx and Yx plane) must fall
within the Tol-O-Matic specified tolerance of 0.0002 inch
per inch…or we don't ship it to you.

|
| So,
ever wonder about the straightness of the assembly bench when
some downsized big company that focuses on short-term profits
by "leaning" out the engineering function puts together
your "precision" actuator? Just asking the question. |
|
At
Tol-O-Matic, a Grade 2 surface plate, made of granite to Tol-O-Matic's
specifications, serves as the test bench. Oh…let's not
overlook the use of a laser and retroreflector to validate
the TruTrack's precision performance in two planes: Zx (flatness)
and Yx (straightness). |

"Lost
in Space" is a name of an old TV show, and should not
be a description of where your workload happens to be at
any given moment. (Remember that annoying robot, "Danger,
Will Robinson. Danger!") Uncertainty applies to the
quantum world, not to electromechanical systems. Quarks
are for quitters.
|
|
Here
is relativity for you: Tol-O-Matic constrains the actuator
on the Grade 2 surface so that any measured variation comes
from the TruTrack actuator. From your perspective, any variation
greater than the TruTrack Coefficient is coming from other
sources in your system. Pay special attention to mounting
the actuator. |

| Nature
abhors a vacuum, and you hate the headaches of stack-up tolerances
and common cause variation. In this world, one plus one does
not always equal two. |
|
Axidyne
closed loop brushless servo system = predictable performance.
But if you like what you are getting out of your current electric
drives and controls, Tol-O-Matic can mount the electric motor
of your choice to the TruTrack. |
