Moscow engineer Sergey Sadovnikov has created and patented a benchtop lathe with an improved design. This development has significantly reduced vibrations during equipment operation.
The key difference in the design is the new layout of the bed and the drive unit. In the headstock area, the bed has a closed box-shaped cross-section instead of the open design used in known analogues. In addition, the drive motor and pulley are moved to the outer side of the bed's rear wall.
According to the developer, this solution increases structural rigidity, reduces bending and torsional deformations, and also lowers the transmission of vibrations to the support surface. This should positively affect the stability of the lathe's operation and the accuracy of part processing.
The utility model is intended for benchtop lathes used in small-batch and individual production, training workshops, laboratories, as well as home workshops, where equipment compactness and high precision are particularly important.
The design also includes additional elements that contribute to increased rigidity. These include internal longitudinal cavities, transverse stiffening ribs, a motor plate for mounting drive elements, and technological openings in the bed walls.
Experimental tests showed a consistent reduction in vibration levels as new design solutions were implemented. The best result was demonstrated by the variant with a closed box-type bed, internal stiffening ribs, and a motor plate, where the vibration amplitude was minimal compared to the basic design.
