As we all know, in the daily application of wood cnc router, various errors are inevitable. However, we can still use some technical means to reduce errors, improve the engraving accuracy of wood cnc router, and improve Engraving quality. So, what can we all adjust to achieve this goal?

1. Choose a pair of 25° angular contact bearings at the end of the output shaft to bear the axial and radial loads of the output shaft. Use the bearings in pairs to avoid additional axial force caused by ensuring the axial accuracy of the output shaft, while also improving The rotation accuracy of the tool is improved.

2. The upper end of the output shaft is supported by a deep groove ball bearing, and a certain gap is left from the upper gland, which can ensure that the shaft has a certain expansion and contraction space for high-speed operation and heat, and avoids expansion and deformation of the shaft.

3. The output shaft end adopts taper hole honing to ensure the cooperation with the ER11 tool chuck; the length from the fixed end of the shaft to the tool is as short as possible; these two measures can reduce the radial runout of the shaft.

4. The internal space of the shaft is sealed by the upper and lower glands with sealing rings to prevent dust and engraving chips from entering the internal wear components and improve the service life and accuracy.

Through the above methods, I believe that everyone can effectively improve the engraving accuracy of the wood cnc router, and in the future, we will continue to share more use skills of the wood cnc router with you.
