Description

Gear grinding is the process of finish grinding gear teeth, and is a critical step when manufacturing high precision gearing. Gears with precision ground teeth run more quietly and wear more evently than gears with cut teeth.
Basically there are 2 methods of gear grinding:
1. form (profile) grinding;
2. generation grinding:
- with worm shaped grinding wheel;
- with conical wheel;
- with 1 or 2 saucer-shaped wheel.
Diversity of grinding methods determines variety of design layouts of gear grinding machines. High precision machining requires from the design of these machine tools construction rigidity, accuracy of rotation and movement of their parts
Gear grinding machine 5A**2 for the production of precision spiral bevel gears and hypoid gears. Generative grinding by cup-shaped wheel uses a grinding wheel with a cup-shaped profile on its circumference whose outer edges meshes with the workpiece gear and are chamfered at an angle equal to the pressure angle of the workpiece gear. The rotating grinding wheel finishes those flank surfaces of the two adjacent teeth to which its outer edges are in contact. The workpiece gear requires indexing to finish all the teeth.

We upgrade STANKO gear grinding machines based on SIEMENS or FANUC CNC decisions to provide perfect quality and simple service of the machines.
