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.
Cantilever Type:
Designed to handle heavy die blocks. The Co-ordinate movements are provided on the head and the table is fixed.

Bridge Type:
Custom designed for eroding heavy forging dies, large plastic moulds etc. The electrode head moves on a bridge. Consult factory for detailed specifications.

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.
Features:
• Precision timed square pulse control
• Low voltage operation
• Autolift of tool with adjustable timing during machining    cycle
• Anti arc circuit
• Audiovisual touch indicator with arrestor
• Variable speed servo quill movement.
• Automatic cut off power on completion of job.
• Interlock of automatic tool feed.
• 1.5 multiplier for pulse ON and pulse OFF.
• Current selection from 0.5A to full load current
• Variable servo gain control
• Superfine generator with booster modules
• Adaptive pulse controller
• Fully transistorized solid state circuitry
