Wire Cut Machining (Wire EDM) is a non-contact spark erosion precision manufacturing process that adopts continuously moving metal wire as the electrode to cut conductive materials. Different from conventional CNC cutting, it generates no mechanical cutting force and requires no rigid tool contact. It perfectly solves the processing difficulties of ultra-hard metals, ultra-narrow slits, sharp inner corners and complex 2D profiling, delivering zero-burr, zero-deformation and high-repeatability precision for various molds and mechanical precision components.

Wire Cut Machining Design Guidelines
Active engineering chapter
Compensation, slit ratio and thin plate support
Reserve Reasonable Cutting Compensation Gap
Reserve a 0.01mm–0.03mm compensation gap for mating structures based on wire electrode diameter to avoid zero-gap discharge interference and ensure precise profile replication
Control Slit Depth-width Ratio
Limit the slit depth-to-width ratio within 10:1. Excessively deep and narrow slits cause unstable wire travel and inconsistent cutting flatness
Reinforce Ultra-thin Plate Structures
Add auxiliary connecting ribs for plates thinner than 0.2mm to prevent bending and displacement caused by wire tension and heat concentration.

WIRE / CUT
Wire Cut Production Process
A through-cut route from threading strategy to contour inspection.
Wire cut traveler
The wire entry and full through-path are planned before the first contour begins.
- 01
Review the through-profile
Confirm that every required contour can be penetrated from top to bottom and identify closed profiles that need threading holes.
- 02
Define datum and wire entry
Set a stable positioning reference, entry point, start hole and cutting sequence for all profiles.
- 03
Program compensation and passes
Apply wire-radius compensation and select high-speed, low-speed or multi-cut parameters for the required accuracy and finish.
- 04
Thread and locate the wire
Pass the electrode wire through the workpiece or prepared entry hole, then align it to the programmed datum.
- 05
Cut and finish the contour
Run the programmed XY path and, where required, complete successive trimming passes to refine accuracy and surface condition.
- 06
Inspect profile and cut surface
Verify contour dimensions, slit width, flatness, thickness capability and exposed surface finish before release.

What is the minimum cutting width of wire EDM?
We support a minimum cutting slit width of 0.05mm, capable of machining various ultra-fine micro gap and micro groove structures.
Does wire cut processing produce burrs?
No burrs are generated. Spark erosion cutting requires no mechanical cutting, delivering completely burr-free part edges and eliminating secondary deburring processes.
Will wire cut parts deform?
No mechanical cutting force is applied during processing, ensuring zero deformation for thin-plate and thin-walled precision components with high dimensional stability.
What is the tightest tolerance for wire cut?
Low-speed wire cut processing can achieve ultra-high precision up to ±0.001mm, meeting strict matching requirements of high-end molds and precision equipment parts.
Can you customize complex special-shaped parts?
Yes. We provide custom 2D full-profile wire cut services according to customer 2D/3D drawings, covering all kinds of irregular planar structural parts.
Can you support large-batch production?
Yes. Our standardized production line supports stable batch processing with consistent dimensional accuracy and surface quality.
What is your wire cut delivery time?
