Abstract A tool head in a turning machine comprising: A TURRET SUPPORTING BASE MOUNTED ON A SLIDING BASE MOVABLE IN PARALLEL AND AT RIGHT ANGLE A MAIN AXIAL LINE SPINDLE IN RESPECT TO AN AXIAL LINE OF A SPINDLE, A DRUM-TYPE TURRET PROVIDED ON THE SUPPORTING BASE SO AS TO EFFECT INDEXING AROUND AN AXIAL LINE PARALLEL TO THE MAIN AXIAL LINE OF THE SUPPORTING BASE, AN OUTSIDE DIAMETER CUTTING TOOL PROVIDED AT A FRONT LARGEDIAMETER PORTION OF THE TURRET, AN INSIDE DIAMETER CUTTING TOOL PROVIDED MOVABLE IN PARALLEL TO THE ROTATING AXIAL LINE AND EXTENDING THROUGH THE TURRET, A POWER DRIVING DEVICE FOR THE INDEXING OF THE TURRET, A POWER DRIVING DEVICE WHICH ENGAGES WITH ONE OF THE INSIDE DIAMETER CUTTING TOOLS WHICH IS INDEXED AND PROJECTS IT BEYOND THE FRONT END OF THE TURRET AND RETURNS IT TO ITS ORIGINAL POSITION, AND A POWER CLAMPING DEVICE WHICH EFFECTS CLAMPING FOR DETERMINING THE INDEXING POSITION OF THE TURRET AND CLAMPING OF THE REQUIRED INSIDE DIAMETER CUTTING TOOL.
A tool head in a turning machine comprising: a turret supporting base mounted on a sliding base movable in parallel and at right angle to a main axial line spindle in respect to an axial line of a spindle, a drum-type turret provided on the supporting base so as to effect indexing around an axial line parallel to the main axial line of the supporting base, an outside diameter cutting tool provided at a front largediameter portion of the turret, an inside diameter cutting tool provided movable in parallel to the rotating axial line and extending through the turret, a power driving device for the indexing of the turret, a power driving device which engages with one of the inside diameter cutting tools which is indexed and projects it beyond the front end of the turret and returns it to its original position, and a power clamping device which effects clamping for determining the indexing position of the turret and clamping of the required inside diameter cutting tool.
