? provision introduced in tattoo machine? The technologies set forth in this utility model patent claim introduce new features and refine existing systems to electromagnetic tattoo machines. This new technological design, in addition to reducing maintenance costs, provides greater comfort, operational convenience and dynamism for electromagnetic tattoo machines: 1.7. self-aligning rear flat spring clamp system with self-aligning tabs: this self-aligning clamp system is designed to ensure perfect alignment and guide. The misalignment of the clip causes changes in the parameters of the frequency of the needle, due to the asymmetry of the posterior flat spring flexion line, requiring interruption for realignment of the same. In addition to self-aligning the clip with respect to the rear flat spring, a seat with guides on both sides has been inserted into the chassis to accommodate it. This way, the whole set remains perfectly aligned. 2.7. stress relief system of the rear flat spring caused by its high bending frequency: this stress relief system aims to: extend the service life of the rear flat spring. The sharp corner in the flex line of the posterior flat spring severely compromises the life of the latter, which breaks early due to fatigue, requiring immediate maintenance. 3.7. clamp system for coupling the front, rear, and flat springs and the needle drive bar: this clamp system for coupling the flat springs and the drive bar aims to ensure perfect positioning and alignment of this group of elements between themselves and the machine. Without this technology, misalignment of this group of elements occurs, requiring immediate shutdown for maintenance / realignment. 4.7. Contact spindle locking system: This contact spindle locking system aims to eliminate the harmful effects of friction on the contact spindle thread caused by the locking screw of the current system. In the new technology, contact spindle locking is accomplished by a disc (contact spindle lock) housed
