When we operate large machines, the sound of the machine is generally large, so there will be noise, so that other workers will cause certain troubles. The same is true for precision CNC machining.
How to reduce the noise during manufacturing precision CNC machining parts ?
What are the treatment methods?
1. Civilized production:
More than 30% of gear transmission noise comes from burrs and bumps. Some precision mechanical parts processing plants remove burrs and bumps before the gearbox is assembled, which is a passive practice.
2, to ensure the accuracy of the tooth blank:
The accuracy of the size of the gear hole is required to be distributed around the middle of the deviation of the hole, and is set at ±0.003~±0.005mm. If it is out of tolerance and within the design requirements of the hole, it must be classified and transferred to the cutting process.
3. Control the accuracy of the gear :
The basic requirements of gear precision: After verification, the gear precision must be controlled in GB10995-887~8, the line speed is higher than 20m/s gear, the pitch limit deviation, the ring gear radial runout tolerance, the tooth direction tolerance must be stable 7 levels of precision.
