Precision ground gears are manufactured by using abrasive tires to grind a gear blank to match the desired gear design. These versatile gears are better suited to use with fine instrumentation and other small-scale elements, and in high precision applications.
More accurate complete: Precision ground gears feature a more exact tooth complete than machined or cut gears, which provides better, smoother meshing of equipment teeth for more controlled operation.
More materials options: While machining, stamping, and other manufacturing processes may limit materials options, nearly any metal or alloy can be made into a gear via grinding.
Higher loads & better performance: Due to how they’re manufactured, ground gears are generally in a position to handle higher loads and higher stresses than gears produced via additional means. Floor gears are specially useful in applications that want huge amounts of torque.Thanks to these unique advantages, in most applications, precision floor gears may outperform gears produced through other means. Ground gears deliver smoother Ground Helical Gear Racks performance and greater longevity.
Bevel Equipment – Bevel gears, sometimes simply called bevels, are cone shaped gears designed to transmit movement between intersecting axes. They are often mounted on shafts that are 90 degrees apart, but can be designed for nearly any angle. Another related term you may here is miter gear, which is a kind of bevel gear in which the mating pairs have the 
same quantity of teeth.
Ground Gear – Surface gears are produced by the manufacturing procedure for gear grinding, also called gear tooth grinding. Gear grinding creates high precision gearing, so surface gears are capable of meeting top quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Equipment grinding is especially effective when gears distort during the heat treat procedure and tooth forms no longer meet up with drawing requirements. Both spur and helical gears could be produced using this method.
Helical Gear – As the teeth upon spur gears are cut directly and mounted parallel to the axis of the gear, the teeth upon helical gears are cut and ground on an angle to the face of the gear. This allows the teeth to activate (mesh) more gradually therefore they operate more easily and quietly than spur gears, and may usually carry an increased load. Helical gears are also called helix gears.
