Abstract: Gear cutting machine tool refers to the use of gear cutting tool machining machine tool gear tooth surfaces or rack gear tooth surface and its supporting auxiliaries. Gear cutting machine tool processing principle divided into two categories, profiling method and generation method.
Gear cutting machine tool refers to the use of gear cutting tool machining machine tool gear tooth surfaces or rack gear tooth surface and its supporting auxiliaries.
Gear cutting machine tool processing principle divided into two categories, profiling method and generation method (or called generating method). Profiling method is to use the blade of the cutter shape to ensure the accuracy of the gear tooth shape. Tooth with single points to ensure uniform points of tooth. Generation method is processed according to the gear engagement principle, imaginary tool for gear tooth shape, it is like a pair of gear in cutting by processing gear meshing transmission, gear is processed in a similar meshing transmission process by forming of selecting such assignment, the generation method, with the high machining precision and low roughness, high productivity, and thus is widely used, generation method according to its machining method and the object can be divided into:
(1) Gear shaper: inside and outside more than used for rough and finish machining meshing spur gears, especially suitable for double, multigang gear, when the machine is equipped with special devices, can be processing helical cylindrical gear and rack.
(2) Gear hobbing machine: Can be hobbing spur gears, helical gears, worm gear and spline shaft and other processing.
(3) Shaving machine: According to the principle of helical gear mesh with the gear shaving cutter drives the workpiece (drive the cutting tool or workpiece) rotating cylindrical gear teeth surface gear shaving machine again.
(4) Gear Shaper: used for outer meshing straight tooth bevel gear processing.
(5) Gear milling machine: used for processing of orthogonal and non-orthogonal (shaft angle is not equal to 90°) spiral bevel gears, hypoid bevel gear cutting.
(6) Gear grinding machine: Used for various high precision gear machining after heat treatment.
In addition spline, the spline shaft milling machine also belongs to the category of gear machine tools.
