Features of using magnetic plates for milling machines
If your work depends on working on a milling machine ,
then increasing the number of products should be a
priority for you. A good tool for increasing productivity
will be a magnetic plate.
The magnetic plate for the milling machine will allow you
to process more than one part at once, unlike standard
Cams. And the processing will be carried out with the
utmost precision and efficiency. Let's take a closer look at
all the features of this device.

4. What is a magnetic plate?

Magnetic plates are a special type of equipment for milling machines that is
necessary for processing metal elements, which is necessary for fixing metal
elements on the working surface of the machine under the influence of
electromagnetic attraction.
Prior to their appearance, Cams were actively used to hold workpieces, which
provided maximum retention during operation. But still magnetic plates have a
number of more outstanding advantages in comparison with Cams:
there is an alternative to processing multiple workpieces at once;
the maximum accuracy of the impact is provided, which is associated with the
phenomenon of heating the metal part. It expands, but does not deform like a
part in clamps;
provide high reliability of fastening;
maintain the main performance characteristics at the original level for the entire
period of use;
do not require annual (or more often) inspection and repair activities.
But the disadvantages are also present in these devices:
not used in jobs that require a large cutting force;
the residual magnetism of workpieces made of steel, but this feature will help to
cope with the demagnetizer.

• Help! Demagnetizer
(demagnetizer) - it is necessary
to remove the forces of
attraction of the tool or
workpiece, so that metal chips
do not stick to it.
• Magnetic plates are most often
used on grinding, milling and
lathes for processing metalcontaining products.
Important!
Magnetic plates are very rarely included in the basic configuration of the
machine, so they must be purchased and installed separately, taking into account
the necessary parameters of the product.

• Design features
• The main structural elements of a magnetic
plate for a milling machine are:
• The device body is made of soft steel. Its base
has special oppositely charged protrusions.
• A special cover that covers the work surface. The
cover is one pole, and the rest of the surface is
the opposite pole.
• Coils-designed for direct current transmission.
• A magnetic block is a mobile element that
moves due to the operation of an eccentric top.

7. Technical parameters

• Technical conditions for the production of magnetic plates are
regulated by GOST 16528-87. It describes all the characteristics of
plates with different types of control.
• The main parameters that affect the operation of magnetic plates
are:
• Overall dimensions-minimum starting from 10x25 cm and
maximum up to 32x100 cm.the final dimensions of the workpiece
depend on this value. Also, due to the large size of the plate, the
load on the machine's work table increases.
• Magnetic force-acts constantly and out of working position it is
prevented by blocks of non-magnetic material. The limits of this
value are 50-120 N / cm2.
• The distance between the magnetic poles or coils. It determines
the smallest size available for the manufactured part.

The principle of operation of the magnetic table
The principle of operation of the plate is quite simple and clear. A magnetic field is formed on its
working surface, which fixes the metal workpieces. This function makes it possible to process not
only the outer part of the materials, but also the side areas.
If necessary, multiple parts can be processed at the same time. Due to its magnetic properties,
you can install an additional tool on the work plane that will be useful in your work.
Operating instructions
The magnetic plate should be unserved and the equipment passport should be examined.
Place it on the machine table.
Check the correct attachment and get started.
The workpiece made of ferromagnetic material must be placed on the work surface in the desired
position and turn the lever 180 degrees. Check the reliability of the attachment.
To begin processing of the workpiece.
Metal shavings that form during operation can be removed with a brush after turning the handle
180 degrees. Then, after cleaning the surface, it is necessary to re-fix the workpiece with the
handle.
At the end of the work, turn the handle and remove the workpiece.
Important!
The impact of the shock load on the workpiece fixed on the magnetic plate is unacceptable, since
this leads to a decrease in the magnetization of individual elements and, accordingly, to a
decrease in the forces of attraction

Expert advice and price
The best-selling models of magnetic plates are:
MP 400x125 sine 2S7208-0003. Its advantage is a reliable clamping of workpieces using magnetic
currents of permanent magnets, which guarantees a constant clamping force for the entire time of
operation. The price of such a device is from 50 thousand rubles.
MP 250x100 (7208-0001) - slightly cheaper than the previous model, sold from 19 thousand rubles.
MP flat X91 300x680 (66120-6) - makes it possible to process parts with a minimum thickness of 8
mm/7 mm. its cost - from 170 thousand rubles.
It provides a reliable fixation of the workpiece, which affects the quality of the work. We are also
pleased with the property of this device that the technical parameters and the possibility of using such a
design remain the same over time. This quality is the reason why customers are interested in
electromagnetic stoves
