The Coborn TL1 is the dual-purpose table lapping and wheel preparation machine. The TL1 may be used to generate the final cutting edge on SCD tools (new or repaired) after polishing on Coborn’s PG range of machinery, the PG6 and the PG3B. The TL1 can also be used to prepare a polishing wheel before use. A prepared polishing wheel is paramount in generating low-waviness SCD tools.
