Tooth edge rounding and sharpening machines are specialized machines used to finish the edges of gears. Tooth edge rounding machines are used to round the edges of gears to reduce friction and wear and improve the transmission process. The rounded edges also increase gear life and improve transmission efficiency. Tooth edge sharpening machines are used to sharpen the edges of gears to make them ready for use in applications where high transmission accuracy is required. A sharp gear can allow for precise transmission of torque and increased efficiency. Both types of gear edging machines are used in a variety of industries, including automotive, machine building, aircraft and aerospace, to name a few. It is important to note that each type of gear edging machine is designed for a specific application to ensure a high level of precision and accuracy.
