Precision floor gears are manufactured by using abrasive wheels to grind a gear blank to match the desired gear design. These versatile gears are better suitable for use with fine instrumentation and other small-scale components, and in high precision applications.
More accurate finish: Precision 
ground gears feature a more precise tooth complete than machined or cut gears, which provides better, smoother meshing of equipment teeth for more managed operation.
More materials options: While machining, stamping, and other manufacturing processes may limit materials options, nearly any metallic or alloy can be made into a equipment via grinding.
Higher loads & better performance: Due to how they’re manufactured, floor gears are generally able to handle higher loads and higher stresses than gears Ground Helical Gear Racks produced via other means. Surface gears are especially useful in applications that want large amounts of torque.Thanks to these unique advantages, in most applications, precision floor gears can outperform gears manufactured through other means. Surface gears deliver smoother overall performance and greater longevity.
Bevel Gear - Bevel gears, sometimes just known as bevels, are cone shaped gears made to transmit motion between intersecting axes. They are often mounted on shafts that are 90 degrees aside, but can be designed for nearly 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 number of teeth.
Ground Gear - Floor gears are made by the manufacturing procedure for gear grinding, also known as gear tooth grinding. Gear grinding produces high precision gearing, so ground gears are capable of meeting top quality requirements (AGMA, DIN, JIS or ISO) than cut gears. Gear grinding is especially effective when gears distort during the heat treat procedure and tooth forms no more fulfill drawing requirements. Both spur and helical gears can be produced using this method.
Helical Gear - While the teeth on spur gears are cut directly and installed parallel to the axis of the apparatus, the teeth on helical gears are cut and ground upon an angle to the facial skin of the gear. This enables the teeth to engage (mesh) more gradually therefore they operate more easily and quietly than spur gears, and may usually carry a higher load. Helical gears are also called helix gears.
