Core working principle (swing cutting)

source of motivation
German FEIN overtone Z-type cutting machine accessories and tools in stock

The internal motor of MultiMaster converts rotational motion into high-frequency, small angle oscillations (usually 1-3 °) through an eccentric mechanism, with a frequency of up to 18000-20000 times per minute.

Blade movement mode
The blade swings rapidly left and right around the installation axis (not rotating or reciprocating in a straight line). Every small swing, the blade cuts/scrapes the material once.

Cutting mechanism

The blade continuously cuts, tears, and scrapes away material molecules/fiber structures under high-frequency oscillation.

Compared to rotary saws, it has smaller swing amplitude, more concentrated cutting force, less prone to edge breakage, lower heat generation, and is safe.

The role of Starlock interface
3D bite structure, zero clearance, high rigidity, transfers 100% of the machine's swing power to the blade, without slipping, losing force, and with minimal vibration.

Taking 63903125017 (Z-shaped rubber cutter) as an example

Z-shaped bending design: allowing the cutting edge to penetrate into the gap/corner, and still fully contact the adhesive layer when swinging, scraping and cutting the sealant/glass adhesive.

Applicable materials: Soft rubber, rubber, polyurethane, silicone rubber, soft plastic, etc., separated by high-frequency scraping and shearing.
