摘要： A machine tool includes a pallet change unit (20) in front of the main machine (10). The main machine (10) includes a table (12). The pallet change unit (20) includes a pallet change base (21), a pallet change slider (22), and a pallet turning arm (23). The operator door (50) partitions between the main machine (10) and the pallet change unit (20). The access door device (100) includes a machine entry door (110) and a first internal machine cover (120). The machine entry door (110) is mounted on a main body cover (26) of the pallet change unit (20) through a hinge (112). The first internal machine cover (120) is mounted on the open edge of the machine entry door (110) through a hinge (122). On the open edge of the first internal machine cover (120), a second internal machine cover (140) is mounted through a hinge (142). The second internal machine cover (140) is guided by a linear guide (150) and a reciprocating-movement control mechanism (155).
