FLARE™

ESS Flare™

Extended Lenth Deburring Brushes for CNC Machines

The ESS Flare™ line of Cross-section deburring brushes is engineered specifically for high-precision internal bore and intersecting-hole burr removal and polishing applications. These tools are ideal when you need controlled edge-blend and burr elimination in cross-secion, ports, valve bores, and tight-tolerance interior passages—with minimal impact on the surrounding geometry.

Why Flare™

Delivers clean, burr-free ports and cross-sectionwithout altering bore size or shape
Enables automated, repeatable finishing with minimal operator intervention
Reduces secondary hand-deburring operations and improves part throughput
Maintains tight tolerances and surface integrity, avoiding post-process inspection issues

Process Guidelines

Secure the tool in a spindle or toolholder; ensure proper collet grip and tool balance.
Extend the brush into the bore until fully inside; engage at programmed speed while ensuring steady contact.
Use reciprocating or helical motion across the deep-hole intersection for uniform burr removal and surface refinement.
Typical recommended speeds range from 6 000 rpm to 12 000 rpm depending on diameter and material. Feed selections may range 200 mm to 1 000 mm per minute in automated setups.
Coolant, air purge, or mist lubrication is advised to manage heat and keep debris cleared for optimal finish.

ESS Flare™ brushes are the advanced choice when you face the challenge of deburring deep hole and intersecting passages in precision components. With ceramic-fiber filament construction, customizable geometry, and high durability, Flare enables burr removal, edge-blend and finished bore polishing—all while preserving critical dimensions and geometry integrity.

Features & Applications

Ultra-fine ceramic-fiber filaments provide high centrifugal grinding force through thousands of micro-cutting edges on each filament tip.
Minimal damage to workpiece bore: The design ensures that after processing the inner cross-sections, the metal surface remains essentially unchanged, with no visible scratches or deformation.
High structural stability: More durable and dimensionally stable than conventional abrasive nylon brushes—retains shape and delivers consistent results over life.
Wide material compatibility: Suitable for aluminum, copper, magnesium alloys, stainless steel, iron, and precision machined components with burrs < 0.2 mm in size.
Customizable geometry and reach: Rod lengths, shank diameters, and filament configurations can be tailored for deeper holes or complex cross-geometry workpieces.
