How does the stability of a Hammar N80 hobbing machine affect the quality of the machining?

Hamai N80 hobbing machine stability on the processing quality has a variety of important impact, specific as follows:
1. Affect the precision of tooth shape: poor stability of the hobbing machine will lead to deviations in the relative motion between the tool and the workpiece. For example, in the hobbing process, if the machine tool vibration, the cutting trajectory of the tool will deviate from the theoretical path, so that the processed tooth shape error, such as irregular tooth shape, tooth surface roughness increase, etc., affecting the gear meshing accuracy and transmission smoothness.
2. Impact on tooth direction accuracy: poor stability may make the table in the feeding process to produce shaking or offset, resulting in the hob in the tooth direction of the cutting position is not accurate, resulting in tooth direction error. This will make the gear in the transmission process is not uniform force, reduce the bearing capacity and service life of the gear.
3. Influence the accuracy of tooth pitch: the instability of the machine tool will make the movement accuracy of the indexing mechanism is affected, resulting in the workpiece in the indexing process error, which in turn affects the uniformity of the tooth pitch. Insufficient pitch accuracy will make the gear transmission vibration and noise, reduce transmission efficiency.
4. Affect the surface quality: hobbing machine vibration or movement is not stable will make the tool vibration in the cutting process, leaving vibration lines on the tooth surface, increase the roughness of the tooth surface. In addition, the unstable cutting process may also lead to increased tool wear, further affecting the processing surface quality.
