Drilling hole reaming difference
Reaming: generally with a fixed size reamer or adjustable size of the reamer in the processing of holes on the basis of further cutting, the purpose is to improve the accuracy of the hole.
General processing equipment are desktop drilling machine, radial drilling machine, lathe and so on.
Drilling: holes that are machined directly on the workpiece and have a nominal diameter hole (the aperture is usually about 0.2 MM larger than the nominal size and the hole wall roughness is often worse than 6.3μM).
Reaming can be divided into semi-precision hinges and precision hinges, aperture error should be able to control within 0.01MM, the hole wall roughness is generally 0.4-0.8μM.
