Shamir spark machine black sealing strip 130001622 slow wire accessory
Product Introduction – Shamir Spark Machine Black Sealing Strip
Part Number: 130001622
Model: Black Sealing Strip for slow wire EDM
This Black Sealing Strip is a precision consumable designed for wire-cut EDM machines, particularly Charmilles FO models (e.g., FO3X, FO350). It serves as a sealing or protective strip that helps maintain optimal flushing during slow-speed wire cutting operations.
Typically installed adjacent to the cutting wire, this strip prevents dielectric leakage and minimizes contamination, ensuring stable machining accuracy, longer dielectric fluid life, and consistent cutting performance—especially crucial during fine-detail or slow-speed operations.

FAQ Guide – Black Sealing Strip (130001622) for Slow Wire EDM
1. What is the black sealing strip used for?
The black sealing strip is installed around the upper or lower guide assembly of the wire-cut EDM head. Its purpose is to maintain dielectric fluid pressure in the cutting zone and prevent leaks, which helps achieve stable spark discharge and high machining accuracy.
2. Which machines is it compatible with?
It is commonly used in Charmilles FO3X, FO350, Robofil 290/440 and other Shamir-style slow wire EDM machines with similar guide head architecture.
3. What are the signs that the sealing strip needs replacement?
Visible cracks, warping, or deformation
Decreased flushing pressure
Dielectric fluid leaking around the wire guide
Increased spark instability or surface roughness
4. How often should the strip be replaced?
Depending on usage, material type, and maintenance conditions:
Every 400–800 hours of operation (average)
Or during each scheduled preventive maintenance cycle
5. How is the sealing strip installed?
Remove the worn strip using the sealing strip puller or flat tweezers
Clean the guide slot with alcohol and a soft brush
Press-fit the new strip evenly along the guide rail
Trim excess with a sharp blade if needed
Ensure the strip lies flat and is not twisted
Tip: Use part number 130002101 (installation tool kit) for best results.
6. Does it affect cutting accuracy or flushing efficiency?
Yes — a properly fitted sealing strip helps:
Maintain dielectric fluid flow direction and pressure
Avoid fluid turbulence, improving spark stability
Minimize wire vibration, improving cut precision and surface finish
7. What other parts should be inspected at the same time?
Upper and lower wire guides (diamond inserts)
Guide block O-rings and lip seals
Flushing nozzles and jet pipes
Roller bearings or idlers
These components all work together with the sealing strip to ensure optimal EDM performance.
8. Is the material ESD safe or heat resistant?
Yes. The strip is made from EDM-compatible synthetic rubber or polymer materials that are resistant to dielectric fluids, heat, and erosion from electric discharge exposure.
9. Can this part be reused or rotated?
No. The sealing strip is a non-reusable consumable. Once deformed or worn, it must be replaced to avoid compromising cutting performance.
10. Are there different sizes or versions?
Yes. While 130001622 is a standard length (~2570 mm), there are versions for:
Different wire diameters (e.g., φ0.1 mm, φ0.25 mm)
Different EDM head designs or guide block brands
