Werkzeugmaschine mit Schutzabdeckung für Maschinenteile

摘要

A machine tool is provided which is constructed so that a table pivot mechanism and cables such as a power supply line connected to the pivot mechanism are protected from chips and a coolant. The machine tool comprises: a column movable along the X-axis on a bed (11); a main spindle (12) supported by the column via a spindle head and vertically movable along the Y-axis; and a rotatable table (13) which is movable back and forth with respect to the main spindle (12) along the Z-axis on the bed (11). The table (13) is pivotally supported by a table frame which is movable along the Z-axis along slideways provided on the bed (11). A pivot mechanism such as including a servo motor and a reduction gear mechanism for pivoting the table (13) is provided on an outer side of the table frame. The bed (11) has a center trough in which a chip conveyer (18) is provided. The slideways and the table pivot mechanism are completely separated from a machining space by movable covers (22).
