[0002] As modern equipment manufacturing develops towards high efficiency, high precision, and economy, metal sawing has become an important part of parts processing. Currently, band saws are generally used to saw metal parts.

[0003] like Figure 7 As shown, a traditional band saw beam traveling mechanism includes a drive mechanism and a guide mechanism located at the bottom of the saw beam. The drive mechanism includes a servo motor, a reducer, and symmetrically arranged transmission mechanisms. The transmission mechanism includes a drive shaft and gears located on the outside of the drive shaft. The servo motor is connected to the two drive shafts through the reducer. A rack is provided on the band saw frame at a position corresponding to the gear.
