With the GMO deburring tool, bores can be deburred using two machining methods. In most cases, it is sufficient to work with the spring force of the inserted pressure spring. In addition, the pressure spring can also be replaced by an M3 screw so that defined chamfers can be created or larger burrs removed in a rigid setting. This is useful for threaded holes, for example. Regardless of the hosen machining option, the tool must be assembled and adjusted so that the centre of the front Blade meets the edge of the hole, depending on the diameter of the hole to be deburred.

DEBURRING WITH SPRING FORCE Various pressure springs with different pressure forces are available. The spring is selected according to the deburring strength or material properties. E.g. for aluminium a weak spring, for stainless steel a strong pressure spring. In addition, the pressure force can be adjusted via the adjusting screw. The spring force is to a large extent decisive for the deburring strength.

DRIVE IN Position the centre axis of the deburring tool on the centre of the bore. Adjust the swing-out dimension so that the centre of the Blade meets the edge of the hole. The tool is pressed towards the axis against the spring force.	DRIVE THROUGH THE BORE Drive into the hole with the tool rotating and at a high feed rate (approx. F=500). The front tool edge is rounded to allow an easy entering and to prevent damage to the outer chamfer.	DEBURRING THE BACK OF THE HOLE Only drive in until the tool swings outwards and the offset tool neck rests against the hole. Then retract from the hole at a low feed rate, depending on the desired deburring intensity (about F=100).

DEBURRING WITH RIGID SETTING The spring is removed and replaced by the enclosed M3 screw. The swing-out dimension is now precisely adjusted and fixed with two screws. With the help of the tool simulation and the free programming support, optimal machine programming is possible.

ADJUSTING THE BLADE. Position the centre axis of the deburring tool on the centre of the hole. Adjust the swing-out dimension so that the centre of the blade meets the edge of the hole. The spindle or the workpiece must be adjusted in the Z-direction so that the cutting blade can pass through the hole without contact.	TRAVERSING THE HOLE After adjusting the blade, drive rapidly through the hole without rotation.	ADJUSTING THE BLADE Then reset the spindle or the workpiece by the adjustment value. Now switch on the rotation and move slowly upwards until the desired chamfer is reached. The rotation is now switched off. The spindle or the workpiece is moved by the adjustment value so that you can move out of the hole with a rapid traverse.
