The efficiency of low-speed wire cutting processing
Working Principle
Wire EDM uses a thin metal wire as an electrode, typically made of brass or molybdenum. During machining, the wire continuously moves between two conductive rollers and maintains a gap with the workpiece. A high-frequency pulse power supply generates spark discharges between the electrode wire and the workpiece, causing local high temperatures that melt or vaporize the workpiece material, gradually cutting it into the desired shape and size.

Machining Steps
Step 1
Design Machining Path
Based on the part's drawings, use CAD software to design the machining path and generate the corresponding CNC code.
Step 2
Install Workpiece
Fix the workpiece on the worktable, ensuring its position and clamping method meet the machining requirements.
Step 3
Set Machining Parameters
Set appropriate pulse power parameters, feed rate, discharge gap, etc., based on the material characteristics and machining requirements.
Step 4
Perform Cutting
Start the wire EDM machine, follow the set machining path for cutting, monitor the machining process in real-time, and adjust parameters as necessary.
Frequently Asked Questions (FAQ)
Q
What electrode materials are typically used in low-speed wire cutting?
Low-speed wire cutting (Wire EDM) typically uses a thin metal wire made of brass or molybdenum as the electrode.
Q
How does the spark discharge process cut the workpiece?
A high-frequency pulse power supply generates spark discharges between the wire and the workpiece, creating local high temperatures that melt or vaporize the material to cut it.
Q
What are the main applications of low-speed wire cutting?
It is primarily used for manufacturing precise mold components (cavities, cores, sliders), machining hard or difficult materials, and producing high-precision parts like micro bearings and complex curved surfaces.
Q
What software is required before initiating the cutting process?
CAD software is used to design the machining path based on part drawings and generate the corresponding CNC code.
Q
How are the discharge parameters and feed rate determined?
Machining parameters, including pulse power, feed rate, and discharge gap, are set based on the specific material characteristics and requirements.
Q
Why is real-time monitoring necessary during cutting?
Real-time monitoring allows operators to track the cutting path and immediately adjust parameters as necessary to ensure accuracy and process stability.
