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 seen 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 to 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.
My name is Sean Hennessey
from the engineering department at Misumi USA. In this webinar,
I will be talking about, in detail, our lineup of metal plates,
which are often precision machine blanks. Misumi offers several structural
components including
pre-finished metal plates.These metal plates can be cut to specified dimensions and
tolerances to meet a designer's
application requirements. With a selection of over 30 material types,
Misumi can provide a viable option for any design. Misumi offers three surface
finish machining methods;
milling, rotary grinding, and surface grinding, that provide precise
parallelism, edge squareness, and flatness tolerances. Milling is the most
cost-effective machining method
with the largest range of sizes. Misumi offers plates that are precision milled
on
two, four, and six sides. The rotary grinding process provides tighter parallelism,
edge squareness, and flatness tolerances than the milling process.
However, Misumi only offers the rotary grinding
for the top and bottom sections of the plate. The surface grinding process
achieves parallelism,
edge squareness, and flatness tolerances that are similar to the rotary griding
process.
But surfaced ground plates offer better thickness tolerance.
Surface grinding is only offered for the top and bottom sections of the plate.
Misumi has several different machining methods that use a combination of the
surface finish machining methods
with standard machine methods, such as unpolished milling and precision saw cut.
The first option is 2F, where the top and bottom of
the plate are precision milled and the four sides of the plate are rough cut.
The next option is 2RG, which is the
rotary ground for the top and bottom sections and cut on the side of the
plate.
The third selection is 4SC, that is precision milled on the top and bottom,
and use a precise saw to cut the length and the width of the plate.
The 4f option is precision milled on the four sides of the plate
while the top and bottom are unpolished. The 6F option is precision milled on
all six sides.
The 4F2RG machining method
is rotary ground on the top and bottom portion to the plate, and the four sides
are precision milled.
The final selection, 4F2G,
is surface ground on the top and bottom and precision milled on four sides of the
plate.
For these machine options, the increments that the length, width, and thickness can
be configured by
is dependent upon the material. Misumi offers several different tolerance types for
the A, B, and T dimensions of our metal plates.
The types are plus/minus, plus/plus, 0-to-plus,
and minus-to-plus. The tightest metric tolerances offered by Misumi are;
+.05 to -.05 millimeters
for the A and B dimensions, and +.01 to
-.01 for the T dimension.
For inch, the tightest range is +.002 to
-.002 inches for the A and B dimensions,
and +.001 to -.001
for the T dimension. In addition, Misumi plates with surface finish machining
have geometric tolerances for edge squareness, flatness, and parallelism.
Edge squareness is the variation between two surfaces
oriented 90 degrees to each other. This tolerance can apply to any edge formed by two
surface machine sections.
The parallelism tolerance is the degree to which the surface of a plate
can vary from a datum surface. The flatness tolerance is a zone consisting of
two parallel planes within which the surface of the plate must remain.
Now I will explain the advantage of using Misumi's precision blanks.
At standard machine shops, a stock size plate
is cut the required dimensions and the remainder is scrap.
Next, using a vertical mill, the top and bottom of
the plate have to be machined individually, and chinning
is typically required to achieve the proper tolerances.
Finally, the plate is squared by milling one side at
a time. With Misumi, you can avoid this tedious process
and receive precision blanks ready for secondary operations, saving time and
money.
Misumi uses duplex mills to achieve superior
edge squareness, flatness, and parallelism. These improved tolerances
are possible because the duplex mill machines two faces simultaneously.
Additionally, CNC machines rotate the plate ninety degrees
to provide improve squareness. For all machined Misumi plates,
there's a reference datum that is identified with a sticker. This datum will allow you
to maintain tolerances during secondary operations.
Now I will show the different metal plate offerings and overall size range.
For these materials, the available size range is dependent upon the machining
option. Metric machining options are marked in green,
and inch are marked in red. 1018 is one of the most common steel grades with good
machinability and low price.
It is widely utilized for its high ultimate strength as compared with lower content
steels.
1018 annealed carbon steel has relieved residual stress.
This allows for improved dimensional stability
during machining. 1049 is a medium carbon steel with better toughness,
strength, and durability
than lower carbon steel groups. 1049 thermal refined carbon steel uses a
quenching and tempering process to obtain a hardness
of 22-28 HRC. 1055 normalized carbon steel
is air cooled to relieve internal stresses and has a higher mechanical
strength than 1049 carbon steel.
When heat treated, this steel yields a high
surface hardness with good toughness. 303 stainless steel
has a high sulfur composition, which improves material machinability,
but lowers corrosion resistance. It is non-magnetic but can become
slightly magnetic when cold-worked. 303 annealed stainless steel is heat treated
to remove residual stresses.
This improves the dimensional stability while machining.
It is not magnetic but can become slightly magnetic when
cold-worked. It is less corrosion resistant than un-annealed 303 stainless steel.
304 stainless steel has high ductility and excellent drawing,
forming, and spinning properties. It is not magnetic but can become slightly
magnetic when cold-worked.

is one the most common grades of pure titanium class 2.
It is well balanced in machinability and strength. This material is lightweight
and corrosion resistant.
4140 is a chromium steel containing small amounts of molybdenum,
and has excellent abrasion resistance and toughness.
For our metal plate offerings, Misumi also offers alterations for
chamfering and corner cuts. The chamfer size option table lists the chamfer sizes
that can be specified.
For corner cuts, you can specify four equal size cuts or
individual cuts for each edge. Misumi also offers
cold rolled flat bars and thin sheets for several of the materials mentioned in the
previous slides.
The cold rolled flat bars have selectable width and thickness dimensions,
whereas the A dimension can be specified in one millimeter increments.
This part is only precision milled along the A dimension length.
The thin sheets are offered with smaller thickness options than the standard
plates.
The stainless steel thin plates are offered with several finishes including
2B, Number 400, and Number 1.
Misumi also offers brass and tough copper pitch thin plates.
The copper is made from C11000 material and the brass is made from C2801 P material.
Let's visit Misumi's website and show an example of the configured
metal plate.
This is Misumi's globally recognized home page. Misumi is divided into three
divisions;
Automation Components, Press Die Components, and Plastic Mold Components.
We will be focusing on the Automation Components for this webinar,
so I will select the Automation Components icon. The Automation Components home page
showcases our major product categories on left hand side,
and sub-categories in the pictorial index on the right.
For this session, we are focusing on metal plates.
Because Misumi offers such a wide selection a metal plates,
a new website called Automation Materials was created
to display all the metal plate options offered with and easy-to-use configurator
tool.
You can access Automation Materials by clicking on the banner or by entering
automationmaterials.com
into your URL. From here you can see the material machining tolerance
and alteration options that are available. You can also click on the Properties button to
find descriptions and properties for each material type.
The first step to building
your part number is to select the material. For this example,
I will select 5052 aluminum.
Next I will select the machining option. The machining options are available for 5052
are
4F 6F, and 4F2G.
I will select 6F. Now I can enter the dimensions for my plate.
For 5052 with 6F machining,
there are both inch and metric options. I will select metric for this example.
The first dimension I will enter is a thickness of ten millimeters because the
available size ranges for length and width
are dependent upon it. I can select my tolerance range for the thickness,
+/- 0.05 millimeters,
in the drop down box below. You can also leave the tolerance blank
and a standard tolerance will be provided. Next I will enter my width of 250
millimeters,
and I will leave the tolerance drop-down empty. Lastly, I will specify my length.
Since my length needs to be larger than my width, I will enter a value of
600 millimeters
and not specify a tolerance. For the chamfer, I will leave it unspecified, which
means that a standard chamfer will be applied that breaks the edges.
The last option is for corner cuts. I will select an individual corner cut of
3mm
for one of the edges. I then enter my Quantity, 3,
and hit the see matching products button. The part number will be displayed below
with the specifications, pricing and delivery. I will now show some
application examples using Msumi metal plates.
The first example uses a metal plate as
and installation base for a linear assembly. The edge squareness tolerance enables a
designer to precisely machine holes and other features into the plate.
These holes can be used to accurately position a variety of linear mounting
supports. This is a similar example where metal plates are used as a base for a
check fixture.
The edge squareness, flatness, and parallelism are critical for ensuring the accuracy
and precision of dimensional inspection applications.
The final application is for a coordinate-measuring machine,
or CMM. The metal plate serves as a base for the object being measured.
The high flatness tolerance is essential for precisely measuring a part's
characteristics.
Our last example shows a simple linear actuator assembly
that's completely made up of Misumi components. We showcase our metal plates in
this presentation,
but Misumi offers a wide range of complementary products such as linear
shafts, bushings, collars, and
many other components to complete your automation assembly needs.
