Abstract:
A CNC milling machine comprising:a motor;a main transmission shaft driven by said motor;an upright shaft provided with a transmission wheel adopted to be actuated by said main transmission shaft;an engagement device having a main shaft which is provided with a connection member, said connection member being provided with an engagement wheel set which is engaged with said main transmission shaft, said connection member further being connected with a connection rod which is coupled with a drive source for actuating said connection member to ascend or descend; anda horizontal shaft provided at one end thereof with a gear set mounted thereon such that said gear set is engageable with said main shaft of said engagement device;said upright shaft being actuated to turn via said transmission wheel set at such time when said main transmission shaft is driven by said motor to rotate, thereby causing an upright cutter to carry out a longitudinal cutting of a workpiece, said horizontal shaft being actuated to turn via said engagement wheel set and said gear set at such time when said main transmission shaft is driven by said motor to rotate, thereby causing a horizontal cutter to carry out a horizontal cutting of the workpiece without transferring the workpiece;wherein said transmission wheel set comprises a first belted wheel mounted on said upright shaft, and a second belted wheel mounted on said main transmission shaft such that said second belted wheel is linked with said first belted wheel by a transmission belt.
