3.3 Double-Edge Dressing Blade

D-Series Products

n the resistance spot welding dressing process, the flatness and coaxiality of the electrode end face directly determine welding stability, electrode cap service life and weld quality of body sheet metal. Stelon double-edge dressing blades are manufactured with high-alloy tool steel and precision grinding technology, drawing on precision blade manufacturing concepts. With symmetrically arranged double cutting edges, they achieve efficient cutting and shaping of the electrode end face in a single dressing operation. Featuring sharp cutting edges, balanced force bearing and smooth dressed end faces, they are widely used in robotic dressing units and stationary dressing & cap changing equipment in automated welding workshops.

Description

Core Advantages

Symmetrical double-edge design for smoother dressed end faces
Adopting a double-edge synchronous cutting structure, the left and right cutting edges bear force symmetrically. The electrode end face is less prone to deflection during dressing, achieving higher end face flatness and coaxiality, and reducing risks of weld offset, cold weld and spatter.
High-alloy tool steel for durable wear-resistant cutting edges
Made of wear-resistant tool steel and processed by heat treatment and precision grinding, the cutting edges feature high hardness and good toughness. They are suitable for high-frequency dressing conditions, effectively extending blade service life and reducing downtime for replacement.
High cutting efficiency and strong cycle adaptability
With optimized geometric structure, low cutting resistance and smooth cutting penetration, the blades are suitable for matching with robotic dressing units, stationary dressers and integrated dressing & cap changing equipment, meeting the demands of high-cycle welding production.
Precise installation positioning for fast and reliable blade replacement
With standardized mounting holes and precision positioning structure, the blades can be quickly installed into the cutter body and clamped stably. The blade replacement process is simple without complex adjustments, helping to shorten equipment maintenance time.
Compatible with multi-spec electrode caps and supports customized development
Compatible with dressing requirements of common standard electrode caps, and customized blade geometry solutions are available based on electrode tip diameter, end face shape, welding gun model and customer’s dressing process, to better match different production lines and robot programs.

Process Application Scenarios
