| Precision ground Vee and flat table ways are
lined with Turcite-B to withstand long wear under
heavy load. The Z axis runs on Swiss Schneeberger
linear bearing ways, a sensitive DC servo motor
and a precision leadscrew and ballscrew provide
both manual and automatic control of the precision
ram movement. |

 |
| JOEMARS EDM utilizes state-of-the-art
circuits for the power supply. All electronics
are transistoried, using MOSFET for enhanced performance.
Dual voltage current being synchronously discharged
allows fast metal removal rate and uniform surface
finish. "No wear" operations with both
copper and graphite are strong features of JOEMARS
EDM. A special micro finish circuit for very fine
surface finish capabilities is another standard
feature. |

 |
| Fine grain cast iron construction on the bed
and column, both with extra wide frame, provides
great strength for temperature and vibration stability. |
|
| |
 |
| All PC boards are sectioned in modular box design.
Terminal blocks are employed for wire connections
between modules. LED lights are used to indicate
the status of the fuses and modules. Maintenance
cost on the power supply is thus reduced to a
minimum. |
|
| |
 |
Low temperature electronics are separated from
high heat components for better heat ventilation.
An independent heat dlimination system is also
provided to ensure reliable performance from the
power supply. |
