Coborn Planetary Skive Bench for Diamond Faceting & Polishing

Coborn Planetary Skive (Scaif) Bench for Faceting and Polishing single-crystal diamond (SCD).  Equipped with 24x36 inch table, 3-phase fixed speed spindle, and an additional planetary motion functionality.

  • Engineered to polish and/or finish single-crystal diamond (SCD) materials including cutting tools, gemstones, and substrates for scientific research.
  • Planetary motion can improve diamond removal rates, polished surface finish, and/or edge quality especially on difficult-to-polish SCD (CVD, HPHT, or Natural).  The relative motion of the wheel and SCD workpiece also minimizes uneven wear of "tracks" in the ferrous skive wheel/plate.
  • The system design offered can be operated with or without planetary motion.
  • Refurbishment includes a new charcoal gray laminated top applied to a thick steel tabletop. 
  • Goods to be sold in tested, refurbished condition with a limited warranty to ensure functionality. 
  • PHOTO NOTE: The unit shown in the attached images has been sold.  However, refurbishment of a similar Coborn unit is ongoing.  Photos of actual unit offered can be provide prior to sale.
