Pay attention! The workers are getting ready to put the Diamond Wire Saw onto the power flywheel of the wire saw machine because today's task is to cut a piece of stone with an area of about 110 square meters. After some preparations, now we can see that the wire saw machine is running rapidly. The diamond wire saw, pulled by the power flywheel, is quickly cutting the stone. We estimate that the task will take about 8 hours to complete. Someone asked me if increasing the diameter of the power flywheel would make the cutting more efficient. In this video, let's talk about this topic.

Hello, everyone. I'm Oliver Mo, who manufactures and sells wire saws. According to the technical parameters of the wire saw machine, the diameter of the power flywheel of this wire saw machine that is cutting the stone is 800mm. If we change it to 900mm, will the cutting efficiency be higher? Actually, it's not the case. From a physics perspective, the moment of inertia is proportional to the mass of the object and the square of the radius of rotation. When the diameter of the power flywheel is 800mm, compared with a 900mm - diameter one, its moment of inertia is smaller. At the moment of starting the equipment, a smaller moment of inertia means that the motor needs to overcome a relatively smaller resistance torque. According to Newton's second law, with the same motor torque output, the wire saw machine with an 800mm power flywheel can obtain a higher angular acceleration more quickly and start rapidly. This is one of the reasons why our wire saw machine can start cutting by itself without manual assistance to pull the wire at the beginning.

If you have a wire saw machine with a 900mm - diameter power flywheel, you can definitely buy a Power Save Master wire saw machine with the same power. Let these two wire saw machines use the same wire to cut stones of the same area and have a competition. You'll be surprised to see which one is faster. Because we've conducted such competitions many times. The two wire saw machines in the video are having such a competition.

Finally, I'm Oliver Mo, who manufactures and sells wire saws. I hope to be your partner on the stone - quarrying journey. If you encounter any problems when buying a wire saw machine, you can contact me privately. See you in the next video.
