Main Mechanical of DNC 42:
1.
 Stainless worktank and watertank design.
2.
 High rigidity mechanical invention, fine therml balance development.
3.
 Stainless workpiece design.
4.
 Machine base designed to assure the accurate stability.
 
1.
100 sets machining condition memories: Can store 100 sets user machining condition.
2.
6 kinds machining parameters: includes peak current, capacitor, on time, off time, spearking gap, and Servo sensitivity.
3.
Function of choosing "Fuzzy" machining condition: through (a) Machining materials, (b)Electrode diameter, (c) Electrode wear, to choose the best machining conditions.
4.
Five kinds of alarm indicators: will be lighten when depth arrival, arcing, low dielectric level, for safety, and a short on electrode and workpiece.
5.
Anti-hitting system for electrode.
6.
Using "MOSFET" sparking circuits, suitable for tungsten carbide, hard alloys, hard steel, and powder matallurgical.
7.
Electrode range from 0.2 to 3.0 m/m, apply to slanting, spherical, and curved workpieces machining.
8.
Arching protecting circuits: automatically adjust "off time" when machining is not stable. If arcing over certain time, sparking will be automatically stopped.
9.
Special high pressure pump design, water come out quickly and with pressure releasing control system in order to reverse water without any droppoing of water.
10.
Using Heidenhain TNC 310 controller with a great amount of "User Cycle".
11.
X,Y, Z3 axes can move at the same time.
12.
Includes RS232-C/V.24 interface, machining programs can be transferred by this interface to external periphery.
13.
Background editing function: available to proceed another program of workpiece editing while machining.
14.
Dialogue type programs editing function provides a simple operation.
15.
TNC 310 controller can store 64 programs, Max.6000 blocks.
16.
Subprogram and program section can be repeatedly performed.
17.
Coordinate datum shift function.
18.
Mirror image function.
19.
Coordinate rotation function.
20.
Scaling factor function. (to enlarge to reduce)
21.
Probling function for finding hole center, workpiece center, X axis center, Y axis center.
22.
Workpiece corner coordinate finding function.
