Precision surface gears are manufactured through the use of abrasive wheels to grind a equipment blank to match the required gear design. These versatile gears are better suited to use with great instrumentation and various other small-scale elements, and in high precision applications.
More accurate finish: Precision ground gears include a more exact tooth complete than machined or cut gears, which gives better, smoother meshing of equipment teeth for more managed operation.
More materials options: While machining, stamping, and other manufacturing procedures may limit material options, nearly any steel or alloy could be made into a equipment via grinding.
Higher loads & better performance: Because of how they’re manufactured, ground gears are generally in a position to handle higher loads and higher stresses than gears produced via various other means. Floor gears are specially Ground Helical Gear Racks useful in applications that require huge amounts of torque.Because of these unique advantages, in most applications, precision floor gears can outperform gears produced through other means. Surface gears deliver smoother efficiency and greater longevity.
Bevel Gear – Bevel gears, sometimes simply known as bevels, are cone shaped gears designed to transmit movement among intersecting axes. They are usually mounted on shafts that are 90 degrees apart, but can be designed for nearly any angle. Another related term you might here’s miter gear, which really is a kind of bevel gear where the mating pairs possess the same number of teeth.
Ground Gear – Floor gears are made by the manufacturing process of gear grinding, also known as gear tooth grinding. Gear grinding creates high precision gearing, so floor gears can handle meeting top quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Gear grinding is particularly effective when gears distort through the heat treat procedure and tooth forms no more fulfill drawing requirements. Both spur and helical gears can be produced like this.
Helical Gear – While the teeth upon spur gears are cut straight and installed parallel to the axis of the apparatus, 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 can usually carry an increased load. Helical gears are also called helix gears.
