2024-05-1046510Although both the gearbox and the deceleration motor are related to deceleration, they are not the same. The difference between a reducer and a reduction motor.The structure of the reducer and the reduction motor are different. A reducer is a mechanical device composed of gears, shafts, racks, etc., which reduces speed and increases torque throug...
2024-05-1042010During the laser marking process, sometimes sparks may appear on the surface of the product marking, indicating that the marking of the product has had an excessive impact on the surface and a high success rate in marking the product. If you want to ensure the perfect effect of the product, users must be proficient in adjusting the power of the mar...
2024-05-1050710UV laser is a special type of laser. Compared to CO2 laser and fiber laser, UV laser emits laser wavelengths ranging from 100 nanometers to 400 nanometers, in the high-frequency range between visible light and X-rays. Within this wavelength range, ultraviolet laser has a very high energy, strong penetration and absorption, and is suitable for many ...
2024-05-0947510High reflectivity and thermal conductivity pose certain challenges to laser welding, including issues such as weld oxidation, thermal cracking, and insufficient penetration depth. Therefore, understanding and timely troubleshooting common faults in aluminum laser welding machines is crucial for ensuring welding quality and production efficiency.1...
2024-05-0944810Laser cladding, also known as laser surface strengthening treatment or laser coating technology, is an advanced material surface modification technology that rapidly melts metal or non-metal powder on the surface of a workpiece through high-energy laser beams, and then cools and solidifies to form a layer of coating with specific properties. This t...
2024-05-0947610Why can't ordinary motors be used as variable frequency motors?
2024-05-0847420Belt driven centrifugal fan is a common industrial equipment that drives the impeller to rotate at high speed through belt drive, thereby generating airflow. However, during use, belt driven centrifugal fans may experience vibration, which not only affects the normal operation of the equipment, but may also lead to equipment damage and safety hazar...
2024-05-08487101. When a water outage occurs, it is usually caused by a significant lack of cold water. In the specific application of industrial chillers, it is necessary to immediately check whether the chiller pump and all chiller control circuits are in a reliable software environment. Only by maintaining the smoothness of waterways can the probability of wat...
2024-05-0841910What is the significance of helical gears in transmissions?
2024-05-0745920What is the difference between DC brushless motors and permanent magnet synchronous motors?
2024-05-0751020The laser is the most important core component of the laser welding machine, so the protection of the laser is very important. Therefore, the premise of doing a good job in the maintenance of the laser is to ensure that the chiller closely related to it is regularly replaced with ionized water, because the purity of the cooling water is the key to ...
2024-05-0745110Because when you start a cut, with whatever dimensions, in the laser machine they come out: one millimeter smaller,on the "X" axis and on the "Y" axis,how to configure in rdworks 8, to solve the measurement problem
