Cranfield Precision's 1604 high accuracy positioning tables complement any coordinate measuring machine.
Extremely low coning errors result from replicating the air lift seat of the tables from masters generated on one of the worlds most accurate diamond turning machines.
High accuracy positioning with good dynamic response is achieved with the proven Cranfield Precision DC friction drive units.
Synthetic granite structure guarantees dimensional stability and rigidity of the base casting.
