       Direct engraving of logo on spherical surface. | 
    
     |  | 
       Direct engraving on a cylindrical surface of an aluminun cap for alcoholic beverages (product photo). Both concave and convex characters are engraved. | 
    
     | Sample Trial production Electrode Product | 
      This intricate model was created manually by converting a resin sample into 3D data using manual techniques, before the widespread adoption of 3D scanners. The process was highly demanding and required significant skill. | 
     
     | Sample Mold | 
      Direct engraving of molds from 3D scanning (outsourcing) using a 3D scanner. | 
    
     | 4-axis rotary processing |  | 
      Roulette electrode machined simultaneously on the X-Axis and A-Axis (rotational axis). (Tool used: tapered with a 45° tip and a diameter of 0.68mm) *Video available.  | 
     
     |  | 
      Roulette electrode with a 1-convex 0.3 profile (tool used: tapered with a 45° tip with and a R of 0.04mm at the ball end). | 
     
     |  | 
      Roulette electrode with a 0.8 convex 0.5 profile. Due to the surface having a steep conical gradient, we tilted the B-Axis during machining. (tool used: tapered with a 38° tip and a diameter of 0.06mm). | 
    
     |  | 
      Twisted surface machining along the circumference using simultaneous 2-axis processing of X-Axis and A-Axis (rotational axis). | 
    
     |  | 
      Direct engraving of internal thread. | 
    
     |  | 
      The engraving for the date printing machine is done using cylindrical interpolation. (Material: Brass). | 
    
     |  | 
      Direct engraving on a focus ring mold using cylindrical interpolation. *Video available. | 
    
     |  | 
      Direct engraving on a bearing cover mold. |
