New Designed WEDM with Auto Wire Threading

I. Benefits of the latest wire cut EDM machine:



1. Operators friendly: As it is equipped with Auto Wire threading and
servo wire tensioning system, and the successful rate of auto wire threading
is more than 96%;

2. Excellent cutting accuracy: ≤±0.005, as it is equipped with fully
close loop control (7 Axis AC servo motors);

3. Higher cutting speed:>200mm2/min and better roughness: ≤0.8um, as it
is equipped with Nanosecond High frequency power.



II. II. Features and advantages:
1. Auto wire threading system:

(1) Extremely simple auto threading structure with a higher successful rate
of more than 96%;

(2) Both manual and auto threading ways are available;

(3) It is suitable for various working conditions, such as curved
workpieces, hollow workpieces, narrow gap workpieces etc.

(4) Batch setting of the threading height or Automatic Z axis sensing to
reduce the programming complexity;

(5) Multiple strategies are available for chip free processing and batch
centralized waste collection;

(6) In case Auto wire threading fails, various response strategies are
available, such as pausing with alarm directly, automatic hole skipping
marking, and retry threading standard holes.



2. Full closed loop control system:



(1) The full closed loop control system uses an optical grating ruler to
achieve micron level positioning accuracy.

(2) Supports external devices such as laser interferometers for secondary
compensation of the machinery tool, to improve the positioning accuracy, re-
positioning accuracy and reverse deviation.



3. Nanosecond high-frequency system

(1) The pulse power supply uses a high-speed DSP + FPGA control structure.

(2) Precision control of each discharging pulse.

(3) Pulse-by-pulse sampling for precise sensing of the machining status,
with feedback for servo control.



4. Efficient CAM and NC software with minimal operation



(1) Powerful and user-friendly programming system

Quickly select whether to pause before or after the step and pause before
step cutting

Supports optional corner clearing function

Supports taper, upper and lower irregular shapes and variable taper cutting.

Supports chip free cutting, which means automatic stepping without generating
waste material, with adjustable step length.

Supports auto wire threading function, with adjustable parameters such as
threading height.

When there are multiple times cutting paths, the rough cutting can be done
firstly, followed by tool finishing. After the first rough cutting and the
waste material removing, then the finish cutting can be done finally.

The built- in taper calculator function allows for the adjustment of the
taper parameters based on the sample cutting.

The built- in function generates various types of curves, such as the
Archimedean spiral.



(2) Intelligent assistance



Supports functions such as offset, material pickup, centering, edge
detection, and circle center finding.

Built -in quick templates for rapidly generating straight lines, rectangles,
circles, and serpentine curves.

Supports AR correction function: by selecting two points on an edge, the
processing path can be corrected automatically.

Supports the function of array processing paths.

Supports the function of selecting multiple paths, automatically sorting
them, and generating processing tasks.



(3) Extremely simple software control



Supports functions, such as single step movement, continuous movement, and
reverse machining.

Support the function of adding and deleting pause points using the mouse on
the UI interface.

Supports the function of modifying parameters for multiple paths with a
single click.

Supports the function of setting different processing parameters for each
path.

Supports the function of modifying electrical machining parameters at any
time.

Supports the function of simulating machining.

Supports the function of alarming in case of errors.

Supports the function of displaying absolute coordinates while allowing the
setting of up to 10 independent sets of relative coordinates.

Supports the Auto wire threading function with the ability to modify
threading parameters and track data related to automatic threading.



(4) Remote status monitoring



Available on multiple platforms: mini program, app, and desktop client.

Remote control anytime, anywhere.

Numbering the machines.

Display processing time.

Display processing efficiency.

Display processing speed.

Display processing progress.

Display current processing status.

The software can be expanded based on the number of the machines.
