ZNC ELECTRIC DISCHARGE MACHINE

EB304N EB606N EB707N

EB808N EB1060N EB1270N

EBN (ZNC) Machine Structure
1. The machine frame has run through FC30 by having heat treatment and annealing process to ensure the metal with high toughness and prevent
deformation.
2. The working table has gone through high frequency induction hardening and surface polishing to increase hardness and decrease tolerance.
3. Ball screws are utilized in X, Y Axis. (EB304N, EB606N, EB707N, EB808N)
4. One V and one flat design for maximum accuracy. (EB304N, EB606N, EB707N, EB808N)
5. The contacting faces of X, Y Axis are TURICE-B for smoother movement. (EB304N, EB606N, EB707N, EB808N)
6. Linear Guide Way and High Accuracy screw are used on Z axis, with PWM servo system (Same class as CNC model) can perform maximum
working efficiency. (EB304N, EB606N, EB707N, EB808N)
7. Back slide is provided for Z axis. (EB304N, EB606N, EB707N, EB808N)
8. Remote Controller is provided to the user.
9. Model that travels more than 800mm on both X, Y axis (EB860N), utilizes precision ball screws on X, Y, Z axis.
10. Model that travels more than 800mm on both X, Y axis (EB860N), utilizes precision Linear Guide Way on X, Y, Z axis.
11. A standard Up/Down door is installed in model that travels more than 800mm on both X, Y axis (EB860N).
12. Model that travels more than 800mm on both X, Y axis (EB860N), the movement of X, Y axis are controlled by servo motor.
13. Model that travels more than 800mm on both X, Y axis (EB860N), the movement of the X, Y axis are relied on a movable column.
