Condition:
The grinder is in very good condition and will be guaranteed to hold .0002 or better tolerances.
This grinder came out of the IBM toolroom and is in excellent condition! The splash guards and
wheel guard will be repainted. We will fabricate new ones out of stainless steel. We will remove
the chuck, grind in the table, grind bottom and top of magnet, and grind five blocks to verify
tolerances which we anticipate will be .0001 or better.
Guarantee:
The machine is guaranteed 60 days.
Price: $12,500.00
