Machine tool having independent type tool post

A machine tool comprising:

• supports with an axis line of a main axis in an axial direction therebetween;
• a rotation tool post detachably connected on one of the supports and rotatable with respect to a first direction perpendicular to the axis line;
• and
• a fastening member comprising at least one body, the fastening member detachably connecting the rotation tool post on the one of the supports,
• wherein the rotation tool post comprises:
• a rotation unit comprising at least one body, the rotation unit configured to rotate in the first direction on the one of the supports;
• an upper fastening unit comprising at least one body, the upper fastening unit at an upper portion of the rotation unit, and detachably fastened to the one of the supports;
• a lower fastening unit comprising at least one body, the lower fastening unit at a lower portion of the rotation unit, and detachably fastened to the one of the supports so that the rotation unit is rotatable;
• and
• a driving member comprising at least one actuator, wherein the driving member is configured to drive the rotation unit and the tool module, and the driving member provided at an upper end of the upper fastening unit;
• wherein the at least one actuator of the driving member comprises:
• a first driving unit comprising an actuator, the first driving unit located at an upper portion of one side of the upper fastening unit and is configured to drive one from among the rotation unit and the tool module;
• and
• a second driving unit comprising an actuator, the second driving unit located at an upper portion of another side of the upper fastening unit and is configured to drive the other one from among the rotation unit and the tool module.

A method of using a machine tool, the method comprising:

• detachably connecting, using a fastening member, a rotation tool post on one of supports of the machine tool such that the rotation tool post is rotatable with respect to a first direction perpendicular to an axis line of a main axis in an axial direction,
• wherein the axis line of the main axis in the axial direction is between the supports,
• wherein the fastening member comprises at least one body, and the fastening member detachably connects the rotation tool post on the one of the supports,
• wherein the rotation tool post, that is detachably connected to the one of the supports, comprises:
• a rotation unit comprising at least one body, the rotation unit configured to rotate in the first direction on the one of the supports;
• an upper fastening unit comprising at least one body, the upper fastening unit provided at an upper portion of the rotation unit, and detachably fastened to the one of the supports;
• a lower fastening unit comprising at least one body, the lower fastening unit provided at a lower portion of the rotation unit, and detachably fastened to the one of the supports so that the rotation unit is rotatable;
• a first hinge unit at an upper portion of the rotation unit and rotatably fastened to the upper fastening unit;
• and
• a second hinge unit at a lower portion of the rotation unit and rotatably fastened to the lower fastening unit.
