introduction：1.Raceway sound Raceway noise is due to imported bearings[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]When rotating, the rolling element rolls in the raceway and generates a smooth and continuous noise，It attracts attention only when its sound pressure level or tone is extremely high。In fact, the sound energy stimulated by raceway sound is limited，As in normal circumstances，High quality bearing track sound25～27dB。This noise is used to withstand radial loads on single-row deep groove ball bearings

introduction：CNCEd cheng note meaning things item 1. White steel knife speed should not be too fast。 2. Copper workers seldom use white steel knives to cut rough，Multi-purpose flying knife or alloy knife。 3. When the workpiece is too high，Should be cut thick in layers with knives of different lengths。 4. Use a large knife to open it up，Use a knife to remove the remaining material，Make sure the margin is the same。 5. Flat surface should be processed with flat knife，Use the ball knife less，To reduce processing time。 6. Copper workers clean the corner，Check the corners firstRsize，And determine what size knife to use。 7. Table levelling
