What Is a High Frequency Grinder?
It is a grinder connected to a high-frequency generator (inverter power supply) that enhances pressure.
Basically, it has a high output, which makes it suitable for steel and uneven material surfaces. In addition, with general grinders, high friction on the surface to be ground causes a decrease in rotational speed, resulting in uneven grinding.
A high-frequency grinder, however, is capable of maintaining a constant output voltage, which is another feature that allows for uniform grinding. Handheld types are the mainstream, and there is no significant difference in disc size. On the other hand, work capacity varies greatly depending on the specifications of the inverter power supply.
Uses of High Frequency Grinders
Due to their high output, high-frequency grinders are used for finishing after welding or coating in mass production line work and construction sites with large work areas.
In ironworking, can manufacturing, steel frames, and bridges, for example, they are used for beat shaving after welding, chamfering of steel plates, and beat shaving after stainless steel welding. In bridge repair work, it is also used to remove paint and tar. They are also frequently used for deburring castings.
How to Select High Frequency Grinders
〇High-Frequency Generator (Inverter Power Supply)
- Work Load and Work Efficiency
Depending on the workload, it is necessary to select equipment with appropriate output capacity on the output side. In general, it is advisable to select one with specifications of 3 to 4 kVA. For further loading, equipment with an output capacity of more than 10 kVA is preferred.
Some specifications allow the connection of two or more high-frequency grinders, enabling a single inverter to operate in multiple locations. The best combination should be selected in terms of work efficiency and cost. - Cost Aspects
On the other hand, the larger the output capacity, the higher the cost. Inexpensive types can be purchased for approximately 100,000 to 200,000 yen. Some of the more expensive models require more than 500,000 yen. - Safety and Maintenance
Smaller output may be preferable in terms of noise and vibration. In addition, if you select a model with a dustproof structure, you can expect long-term use and reduced maintenance costs by avoiding breakdowns.
〇Grinder Grinding Wheel
There are three major types of tip tools for grinding and shaving. Grinding wheels are used for metal materials such as steel and stainless steel.
For even harder materials or concrete, stone, block, and brick, diamond cups are often used.
On the other hand, for painting-related chamfering and surface finishing, abrasive discs are suitable. In addition, the maximum operating speed is specified for the disc material (generally 80 m/s). It is necessary to select one that meets the specifications of the high-speed grinder.
