Precision surface gears are manufactured through the use of abrasive tires to grind a equipment blank to match the required gear design. These versatile gears are better suitable for use with good instrumentation and various other small-scale elements, and in high precision applications.
More accurate complete: Precision ground gears include a more precise tooth complete than machined or cut gears, which provides better, smoother meshing of gear teeth for more managed operation.
More materials options: While machining, stamping, and other manufacturing processes may limit materials options, nearly any metallic or alloy could be made into a gear via grinding.
Higher loads & better performance: Due to how they’re manufactured, surface gears are generally in a position to handle higher loads and higher stresses than gears produced via additional means. Ground gears are especially useful in applications that require large amounts of torque.Thanks to these unique advantages, generally in most applications, precision floor gears may outperform gears manufactured through other means. Surface gears deliver smoother efficiency and greater longevity.
Bevel Equipment – Bevel gears, sometimes simply known as bevels, are cone shaped gears designed to transmit motion between intersecting axes. They are usually mounted on shafts that are 90 degrees aside, but could be designed for almost any angle. Ground Helical Gear Racks Another related term you may here is miter gear, which really is a kind of bevel gear in which the mating pairs have the same number of teeth.

Ground Gear – Ground gears are made by the manufacturing process of gear grinding, also called gear tooth grinding. Equipment grinding generates high precision gearing, so surface gears are capable of meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Gear grinding is especially effective when gears distort during the heat treat process and tooth forms no more satisfy drawing requirements. Both spur and helical gears could be produced like this.

Helical Gear – As the teeth on spur gears are cut straight and installed parallel to the axis of the gear, the teeth on helical gears are cut and ground upon an angle to the face of the gear. This allows the teeth to engage (mesh) more gradually so they operate more easily and quietly than spur gears, and may usually carry a higher load. Helical gears are also called helix gears.
