The 4 1/2 super thin cutting disc makes us a type of cutting piece that is commonly used.
What is the influence of the material being cut on the cutting performance when the user
cuts the cutting piece? Today, the Aurora Abrasives will be introduced to everyone.
As we all know, various abrasives are suitable for different materials to be cut, so
different cut materials have a great influence on the cutting performance. In general,
when a material having a high tensile strength is cut, a corundum abrasive grain is used,
and when a material having a small tensile strength is cut, a silicon carbide abrasive is
used.
The effect of cutting machine performance on the cutting effect:
(1) Cutting machine power N: N = Ft × V.
Ft is the tangential cutting force, V is the
grinding wheel linear speed; where F1 is subjected to abrasive hardness, grinding wheel
self-sharpness, grinding wheel strength, hardness of the material to be cut, size, cutting
place Radial pressure and many other factors determine, and F1 is an important factor
affecting the maximum size of the workpiece.
(2) Cutting machine speed n: The grinding wheel speed determines the linear speed v, which
determines the relative movement speed of the grinding wheel and the workpiece. This is
very important for the cutting efficiency. The higher the speed, the better the strength
is.
(3) Radial pressure Fn at the cutting point: For the cutting method, the tangential force
Ft can be formed by the radial force Fn; the larger the Fn, the larger the Ft; the Fn/Ft
is between 1.5 and 3, but The resultant force F of Fn and Ft is determined by the strength
of the grinding wheel and the strength of the abrasive.
experiment method:
Although there is no quality evaluation in China at present, it will not be enforced;
however, it is necessary for each manufacturer to use some kind of discriminating method
to supervise and control its own products to improve the competitiveness of products in
the market. According to the test results and the characteristics of the products for many years, the following score tables and discriminating methods are proposed; the cutting
efficiency score FT and the durability score FG are measured by the average time and
average consumption of the three cuts, respectively.
F = aFT + (1 a a) FG;
Ft: cutting efficiency score;
Fg: durability score;
The proportion of cutting efficiency in the total score is in the range of 0 to 100%. The
meaning is: only 100% is considered efficiency, regardless of the durability of the
grinding wheel; when taking 0, only the durability of the grinding wheel is considered
regardless of efficiency. Under normal circumstances, when the section of the workpiece to
be cut is large, such as a round steel with a diameter of 60 mm or more, the value of a is
large. For example, when a round steel having a diameter of 20 mm or less is cut, the
value of a may be small, and it is recommended to take 30% to 50%.
According to the above principles, the user selects the cutting wheel to be economical and
convenient to use. The cutting piece has to pass 60 points to pass.
There are a large number of domestic cutting film production enterprises. Because they are
industrial consumables, they are used in large quantities in the market and are suitable
for starting a business. However, if they do not pay attention to quality, they will be
eliminated in the competition. The production experience of the enterprise is very
important. The theoretical guidance is fundamental. Blindly, the grinding wheel
manufacturing is mixed with cement sand, which will never be done well. There is a basis
for formula adjustment. If you do not form a relatively stable customer formula for a
certain period of time, your product quality will never be stable. Quality problems, the
right medicine, the medicine can be removed! The quality improvement of the resin grinding
wheel cutting piece, bearing in mind that the theory must be combined with the actual to
be able to have vitality.
