What are the processing techniques of cutting discs?
How much do you know about the cutting sheet? But it is certain that
the cutting blade is of great help to the large-scale machinery
industry; such as the cutting of steel pipes, if there is no cutting
blade, there is no way to cut it, so it has many applications.
The
cutting disc is used for cutting stainless steel tube, capillary tube,
glass tube, quartz tube, automobile exhaust pipe, brake wire, tungsten
wire, molybdenum wire, copper wire; and other pipe fittings and
filaments, cutting of special steel and opening of workpieces. The
grooves have a good effect. So what is the processing technology of the
cutting blade? The following are the three major processing technologies
of cutting discs.
1. Cold pressing process
The binders
used are wetting agents and powdered resins. Usually used as wetting
agents are liquid phenolic resins, furfural, furfuryl alcohol, cresol,
etc. Most of them are liquid phenolic resins.
2. Semi-hot pressing process
The
pressing temperature is generally 50-65 °C. At this pressing
temperature, the viscosity of the liquid resin decreases, and the
powdery resin can be well integrated, so that the fluidity of the entire
resin system is improved, and it is easier to fully penetrate each
space. The pressure is not too high, and the cutting sheet can be formed
well, and it does not need to be too long, which is especially suitable
for the automatic pressing production line of continuous operation.
3. Hot pressing process
The
mixing requirements are different from the cold pressing process.
Generally, the dry mixing method is used or the abrasive is wetted with
furfural less than 1% of the weight of the abrasive as a wetting agent,
and then mixed with the powder resin evenly.
When
the cutting disc is working, stand on its side and do not operate it
from the front, so as to prevent the grinding wheel from flying out or
breaking and hurting people when it fails. After all, this is working
under high-speed rotation.
