Precision floor gears are manufactured by using abrasive tires to grind a gear blank to match the required gear style. These versatile gears are better suited to use with fine instrumentation and additional small-scale components, and in high precision applications.
More accurate finish: Precision ground gears include a more precise tooth finish than machined or cut gears, which provides better, smoother meshing of equipment teeth for more managed operation.
More material options: While machining, stamping, and other manufacturing processes may limit materials 
options, nearly any steel or alloy could be made into a equipment via grinding.
Higher loads & better performance: Because of how they’re manufactured, floor gears are generally in a position to handle higher loads and higher stresses than gears produced via various other means. Surface gears are especially useful in applications that require huge amounts of torque.Because of these unique advantages, in most applications, precision surface 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 made to transmit motion between intersecting axes. They are often mounted on shafts that are 90 Ground Helical Gear Racks degrees apart, but can be designed for almost any position. Another related term you might here’s miter gear, which is a type of bevel gear in which the mating pairs possess the same quantity of teeth.
Ground Gear – Ground gears are produced by the manufacturing process of gear grinding, also called gear tooth grinding. Gear grinding produces high precision gearing, so surface gears can handle meeting higher quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Equipment grinding is particularly 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 apparatus, 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 smoothly and quietly than spur gears, and can usually carry a higher load. Helical gears are also called helix gears.
