What Is a Tungsten Polishing Machine?
A tungsten polishing machine is a device for polishing the surface of tungsten metal.
They are especially useful for polishing the tips of electrode rods used in TIG welding. Since tungsten is an extremely hard metal, abrasive wheels are made of diamond, cubic boron nitride (CBN), or other materials with high hardness and excellent thermal properties.
Angle is also an important factor when polishing. Polishing at an appropriate angle improves stability and efficiency during welding, resulting in high quality welding. Attention should be paid to the entire polishing process, including the operation of the Tungsten Polishing Machine and the selection of the grinding wheel.
The tungsten polishing machine is an excellent device that contributes to efficiency and quality improvement of TIG welding. Accurate grinding angles and material selection are important, and proper use will ensure efficient and stable welding operations.
Uses of Tungsten Polishing Machines
The most common use of a tungsten polishing machine is to polish electrode rods used in TIG welding, a welding method that uses electrical discharge to generate an arc of light when voltage is applied to the electrode rod and the metal base material. The strong heat of the arc melts the surface of the base material and welding takes place.
Tungsten is used for electrode rods, and a tungsten polishing machine is an indispensable device for electrode rod maintenance. If electrode rods are used for a long period of time, the tips may become deformed. If the deformation is left unattended, melting cannot be done cleanly and welding quality will be affected.
Therefore, the tungsten polishing machine is used to polish the tip of the electrode rod to correct the deformation, thereby maintaining and improving welding quality. Tungsten polishing machines play a very important role in TIG welding operations because efficient and stable welding operations can be realized through proper maintenance.
Principle of Tungsten Polishing Machines
The tungsten polishing machine first sets the angle to be polished by adjusting the screw at the feed port. Polishing at the proper angle is important to maximize the performance of the electrode rod.
Once the feed port position is set, the polisher is turned on and the polishing wheel is rotated. The wheel may be fitted with a cover to prevent hands from touching it while it is spinning, which varies from model to model. Next, an abrasive rod is inserted through the feed port and pressed against the wheel while rotating it clockwise from time to time to sharpen the wheel evenly, and when the polishing is finished, the rod is removed and the switch is turned off.
Note that there are also polishing machines that do not have a cover or position setting function, in which case the polishing wheel is used by itself. A device called a sharpener may be used to facilitate polishing. However, protective equipment should be worn when the wheel is exposed because of the potential hazard.
The tungsten polishing machine is a device that can effectively polish the tip of an electrode rod by using the appropriate angle setting and rotation of the polishing wheel. The polishing is performed at an accurate angle while taking safety into consideration when in use.
Types of Tungsten Polishing Machines
Tungsten polishing machines are used to polish electrode rods used in TIG welding. Three main types exist: bench-type polishing machines, portable polishing machines, and precision polishing machines.
1. Bench Type Grinder
Bench-type polishers are large polishers fixed to a workbench that provide strong polishing power and are suitable for continuous, long-hour work. They are also often used in factories and welding shops because of their stable polishing and high polishing accuracy.
2. Portable Grinder
Portable polishers are easily portable and suitable for on-site work. Despite their compact size, they can provide the necessary polishing power, making them suitable for urgent on-site polishing work. Battery-operated or corded models are available, depending on the work situation.
3. Precision Polisher
Precision polishers are equipment capable of high polishing precision and fine angle adjustment, and are used especially in fields that require high-quality welding. They are often equipped with digital displays and automatic polishing functions, enabling precise setting of polishing angles and amounts. However, they are more expensive and may require specialized knowledge.
