due toelectrical toolsIt is generally used as a portable tool and requires small and light weight. Therefore, this goal is achieved through rationalization of the structure, shape, high-precision processing, strict material selection, and strict heat treatment. Therefore, it is more convenient to use and more powerful, and has many advantages that electric tools do not have. Compared with electric tools, it has the following advantages.
electrical toolsThe service life of the machine mainly depends on the quality of the motor and the wear resistance of the sharpening head. Among them, the motor has a relatively long life. The sharpening head is generally defined as wear parts. At present, the products produced by many electric tool manufacturers adopt an integrated structure, which causes the whole machine to be scrapped once the sharpening head is damaged, which is neither economical nor environmentally friendly. Fortunately, for the newly launched electric knife sharpeners, brands have begun to adopt the design of replaceable sharpening heads. Such products are relatively more cost-effective.
(A).electrical toolsThe initial investment is low, but the long-term use of energy consumption is high, and the cost of tool maintenance and replacement is also high.
(B). The initial investment of pneumatic tools requires the establishment of air pressure pipeline equipment, but the long-term use of energy consumption and tool maintenance costs lower.
(C). The weight of electric tools is generally 3 to 4 times that of pneumatic tools, which is not suitable for long-term work, and pneumatic tools can improve work efficiency.
