Grinding is usually adopted in the production of gel pen nib using tungsten carbide ball, after which we can get a pen nib with smooth surface and high precision.
Conic grinding is generally adopted in the machining process. First, spread blank balls in the counterdie of conic groove, put grinding flat on the top of blank balls, and exert a certain pressure to it, and then remove the rough edges of blank balls through parallel translation of the flat. Through this processing method, the surface roughness of blank balls will be less than 0.02μm, while roundness error less than 0.001mm. The tungsten carbide ball produced in this way can be well used with a variety of inks, and ensure good abrasion resistance, smooth writing, clear writing. In addition, it is also water-tolerant and sun-proof, and has long storage time.
