R
& F Type – Model G-75 ZNC:
The unique feature of this model is the Rise and Fall Work Tank,
facilitating the operator to rise or lower the tank to his convenience
without draining the dielectric. The table is fixed with co-ordinate
movements provided to the electrode head.
Note: ZNC can be offered
with other Models. |

Toolcraft Equi-Energy Generator
supplies the spark gap with square wave pulses at the required
energy level and frequency. The actual energy spent in each discharge
is constant and results in stable and precise machining with superior
Surface Finish. Additionally, the tool feed control system employs
a system in which the pre-Spark ignition delay is used for tool
advance resulting in maximum material removal rate & low electrode
wear.
