The invention relates to a multi-disc head for smoothing rotational shapes,

A disadvantage of all previously known heads for smoothing Rotational molding consists in the fact that the smoothing disks are positioned on the part to be machined by the action of their surface and the derived pressure just roll off. Through the construction or by setting an Direction to the appropriate size, the unevenness caused as a result of chip-removing machining is divided. other rolled. The surface obtained is then not of sufficient quality and is caused by the puncture parts and workpieces wear and tear and thus also a shorter service life. The surface preserved in this way is also more sensitive to corrosion.

The invention eliminates these disadvantages,

Rotational mold is made up of arms and pins for attaching the rotatably mounted smoothing disks. The smoothing discs are mounted in such a way that their axes intersect with the axes of the arms at the points overlooking the arms, whereby they lie in common planes with them; The pivot axes of the smoothing disks deviate from the arm axes by a slip angle _#

A significant effect of the invention is above all that with the help of a multi-disk head made in this way for Smoothing of rotational shapes a mirror surface of the tool of high quality (0.05-0.1) Ra is achieved. The surface of the smoothed surface is solidified and is against wear and tear and cogen the occurrence of corrosion very consistent. The use of a multi-disc head for smoothing rotational shapes, both the exterior and the the internal, which is used in particular on heavy processing machines, where a satisfactory Surface quality is very difficult, allows saving more costly and complicated Grinding machines and devices, with smoothing on classic machine tools when the workpiece is clamped can be made.

The essence of the invention is based on one shown in the drawing Embodiment for storing the smoothing

As can be seen from FIG. 1, each arm 2 of the multi-disk head is mounted on a support pin 1 for smoothing rotational shapes in the body (not shown). The opposite end of each arm 2 is provided with a misaligned pin J on which a rotatable smooth disc 4 is located on a roller bearing ring. The axis O _{2 of} the misaligned pin 3 deviates from the axis O. of the arm by the slip angle cC or fab.

The dust pan head for smoothing rotational shapes works so that it rolls by means of the smoothing disks which are also advancing. The derivative of the rotational movement of the glass panes depends on the rotational movement of the smoothing heads. This is where smoothing comes about
