Welcome to Misumi's New 19-Minute Webinar Series.
For those of you here that are new to Misumi,
Misumi is a global supplier of Configurable Components.
You may ask, why configurable? What is it?
Configurable components solve the designer's dilemma.
A designer has two choices for components; Standard
or Custom. Standard components have a limited selection
and often forced designers to compromise their designs.
These many pluses such as CADs, static part numbers,
fast delivery, often seem inexpensive
and convenient. The other choice is Custom.
Custom components have many drawbacks.
Designers have to make the solid models themselves and all the manufacturing
drawings.
Purchasers too can attest to the long wait for quotes,
the expensive set up charges for short runs, and the long lead times.
We are forced to use custom components though, because of the flexibility.
Misumi offers Configurable,
which is the best of both; easy and flexible.
Configurable components are easy to design with and purchase.
Online, select the product geometry desired,
the material and surface finish, input the size for each configurable dimension
within the range and increments shown.
You'll get a smart part number, instant price and days to ship,
and the CAD model. All of this configurability
is available with our over one million components,
available at misumiusa.com.
Now I'll turned it over to our Misumi engineer.
Hi, my name is Vick Yonata.
I am a product engineer with Misumi's Motion Systems Group
and will be presenting this webinar on Introduction to Positioning Stages.
In today's presentation
we will cover the three types of stages Misumi offers;
Simplified, Standard, and High Precision Stages.
We will also cover the different types of Mechanism offered
on MIsumi Stages, as well as our linear guides
from High to Low Precision. We will also look into the accuracy of the
Simplified,
Standard, and High Precision Stages.
Let's take a look at how our Stages are laid out.
We will first start off with our Simplified Stages.
These basic stages have an accuracy of 0.1 millimeters.
Next would be our Standard Stages.
These stages utilize a dovetail linear guide
and have an accuracy of 0.03 millimeters
or 30 micron. Our final group would be the High Precision Stages.
These high precision stages have an accuracy from three micron
up to 1 micron, and it utilizes a cross roller bearing guide
or a linear ball guide. Now let's take a look at the accuracy
and price point. Once again,
Simplified Adjustment, Standard Precision,
and High Precision Stages. As you can see,
with a different precision accuracy, each series will differ in price.
Our stages have four different types of Feed Mechanism.
Let's explore each one of them. The Rack and Pinion Feed Mechanism
is suitable for applications that require rapid feeding.
Due to the construction of the Rack and Pinion, this mechanism is not suitable
for accurate positioning.
Travel per revolution on the rack and pinion style
is between 17 to 20 millimeters. Feed Screws are suitable for an application that
requires fine feeding.
This Feed mechanism is utilized in many of our stage products,
since this is more economical
than the Micrometer Heads.
Travel per rotation of our Feed Screw is between .5
to 4.2 linear.
Micrometer Heads are utilized on our High Precision Stages.
The Micrometer Head provides high-resolution graduation
of 0.01 millimeters, which is suitable for
precision positioning.
Misumi also offers a graduation notch of 5 micron.
Travel per revolution on the Micrometer Heads is between .25
to 0.5 linear.
This model offers a unique ability by having two types of adjustment;
Coarse and Fine Feeding. Two models are available;
Coarse Fine Handle, and Coarse Fine Micrometer Head.
With Coarse Fine Handle, coarse travel per rotation is
18 to 20 millimeters and fine travel
per revolution is 2.3 to 1.6 millimeters.
With the Micrometer Head, coarse travel per rotation
is point .5 millimeters, and fine travel
per revolution is 25 micron.
There are five different types of clamping mechanism offered, depending on
the model.
With the standard clamp, the clamp plate is pressed against the side of the stage
by a
clamp screw. This is the most inexpensive and standard set up.
With this disc clamp, the stage is immobilized by clamping the disc.
No load is applied on the stage surface. When clamped,
the stage will not drift.
With Opposed Clamp, the carriage is braced by a bolt from the opposite side
of the Micrometer Head. This ball is secured with a nut to improve
vibration resistance
and lock holding power.
With Slit Clamp, the feed handle shaft is clamped directly.
Compared to the conventional models, a larger retaining force can be obtained.
For stationary position drifts the conventional clamp can be used.
The Lever Clamp has a tightening action of a clamp screw
and is managed by a lever for easy operation.
Presented here are the different types of guides offered on Misumi stages.
Each Guide Method has a different precision value.
Dovetail Groove is a sliding contact guide of male and female dovetails,
and smooth movement is provided by the fitting of male groove
and female groove. Typical application suitable for the Dovetail
Guide
would be where high precision is not required.
The Precision Reference at 60 percent and Load Capacity is
80 percent compared to our high precision stages,
which utilizes either the Crossed Roller or the Gothic Arc
Linear Ball.
Crossed Roller are crossed at 90 degree angles in alternating fashion
and are enclosed in the rail, which have a machined v-groove to support the
rollers.
Line contact between roller and v-groove provide high accuracy and heavy
load capacity.
With the linear ball guide, the linear balls are contained in two rails with a
Gothic Arc groove,
which is a combined curve of two arcs.
Stable load endurance is achieved by four contact points
and equal distribution of motion, providing increased durability.
This type of guide is suitable for high precision and heavy load stages.
Here we show the different axis that Misumi offers in our stages.
With all this different axis configuration, Misumi offers several
different sizes to accommodate your load requirements.
Misumi also offers rotary motion,
as well as a Goniometer stage.
This is a simplified view of our stage product as compared by the guiding
method
and axis of rotation. As you can see,
it is divided into three sections; Linear Motion (XYZ),
Rotary Motion,
and the Goniometer Motion.
As we can see from this table, simplified or standard stages are recommended for
coarse positioning applications.
As an example, this can be utilized for adjusting a sensor
or a dispenser. If you're looking to position with higher precision,
we offer several high precision types with linear ball guides to handle the load.
If you're looking for a rotary motion,
Misumi offers rotary stages in either a crossed roller
or linear ball guide.
Goniometer stages is offered in two types;
standard and high precision. Depending on your application,
one of these type will be more suitable for your application.
Let's take a look at our Simplified Adjustment Stages.
As you can see, this efficient design provides coarse adjustment
without having to assemble or disassemble your application
every time adjustments are required.
Here is the remainder of our Simplified Stage product line.
Like the previous stages, you can use two simplified units
to create an XY stage system.
In this application example of our simplified adjustment units,
you will see the picture on the left utilizing our XKNG model
to adjust the X and the Z-axis as a centering adjustment jig
for round bars. The example on the right also utilizes a simplified adjustment
unit.
In this example it is used to position a counter sensor.
In this example, the user needed to adjust the light axis
to align the part to be machined to a one millimeter width.
As illustrated on the picture, the adjustment was done by using slot holes
that resulted in backlash during bolting, which caused difficulty in maintaining the
prescribed
position. After improvement,
we can make the adjustment to the X and Y axis in a precise and simple manner.
Bolting is no longer required, as we can adjust the position by using the feed
screw on the stage.
Also, it is low cost improvement to increase overall efficiency.
This is an example of an IC Chip Modification Unit.
It utilizes the XYKSL Simplified Adjustment stage.
With this setup, you would be able to reposition both the X and the Y axis direction
very quickly.
This is our Standard Precision Stage product line.
These Standard stages feature a dovetail guide, and rack and pinion feeding method.
Also available is the XY stage with the cross roller guide,
utilizing feed screw feeding method.
This is an example of the Standard Precision Stage.
On this example, we are utilizing an XY stage to adjust a laser sensor.
A Rack and Pinion type is the best option for fast feeding
and long travel. Travel per one nut rotation is seventeen millimeter linear.
On this second example, it is used to adjust a displacement sensor.
Be sure to remember to clamp the Z axis in position
to hold the load in place.
This is the High Precision product line. As you will see,
Misumi carries many different variations of High Precision stages.
These were the first stages that Misumi offered.
These are more of the High Precision stages. As you can see,
we have different axis configurations, such as the X and the XY axis.
These are also offered in High Precision Z-axis,
with two different types of guides.
Different configurations such as the XZ rotary table
and Goniometer our are also available on the high precision product lineup.
This is the example of our High Precision stages.
In this example, a machining accuracy inspection unit
is utilizing the XZEG60 stage.
This system utilizes X and Z-axis
to position the laser beam to detect deviation of workpiece
by the reflection of the beam.
Utilization of stages in this design allow for the elimination
of costly CMM measuring tools. Design time and cost was reduced by using the
product listed.
This allowed for the inspection of parts during the production process
and resulted in a positive improvement of the yield ratio.
And this will be the final example for Fine Microscope adjustment.
The use of the positioning stages made it possible to produce an inspection
unit
at low cost.
This is the Misumi website. As you can see,
the website is divided into three different product groups;
Automation Components, Pressed Die Components,
and the Plastic Mold Components. Since we were talking about stages,
we would then go ahead and select Automation Components.
On the Automation Components page, we would then look at
our stages. We have motorized stages,
manual stages, and simplified adjustments.
If you're looking for a Standard and High Precision stages,
we would then click on manual stages.
On this page, we have manual stages
or the peripheral components such as the
Feed Screw or the Micrometer Head, and if you're looking for a replacement
this would be the the page for you to look into.
Since we're looking for a stage we would then click on manual stages.
On the manual stages page we can see that we have a selection
of looking into different axis. You have X axis,
XY axis, Z axis, XZ,
and many many more here.
But let's use the configurator on the left side of the page.
On this particular example, let's take a look at an X axis stage.
So we would then go ahead to select this,
and we'll select a steel as a table material,
and we have two different guide options available here;
either a dovetail slide or a cross roller.
In this case, let's say our application doesn't require
high precision--let's go ahead and select the dovetail slide,
and select 50.1-100 Newton load capacity,
and select
our option here. And as you can see this narrows down our option
to one stage. We'll go ahead and select that,
and here comes our complete part number. Part Number XWGSR40.
On this page, we can then
check into the pricing,
and as well as checking on the lead time from these tabs on the bottom.
We would then click on Days to Ship,
three days, and if we need more information
we can always click on catalog.
It will show you the dimensional drawing and more
detailed specification.
And this concludes our presentation for today. Thank you for attending.
