Cogsdill Madison Microroller ID Burnishing Tool MT3 Shank 6408-011-00172 11"OAL For Sale

Item #5450.0001" - .0025mm adjustable
The Cogsdill Madison Microroller ID Burnishing Tool (Part: 6408-011-00172) is a high-efficiency precision metal-finishing tool designed for internal diameter (ID) sizing and surface conditioning. Rather than removing metal like grinding or honing, it uses planetary rollers to cold-flow microscopic surface peaks into valleys, creating an ultra-smooth, work-hardened profile.Technical SpecificationsTool Series: Madison Microller / Roll-a-Finish internal tool line.Shank Profile: Number 3 Morse Taper (MT3 Shank) for secure, heavy-duty rigid mounting in machine spindles or tailstocks.Operational Mode: Internal Diameter (ID) sizing and multi-roll burnishing.Adjustment Range: Adjustable in precise 0.0001-inch increments using a spring-loaded rear adjusting collar.Target Surface Finish: Capable of producing mirror-like surface finishes as fine as 2 micro-inches (0.05 micrometers).Operational MechanismsCold Flow Displacement: Displaces metal rather than cutting it, drastically improving wear resistance, seal life, and load-carrying traits.Work Hardening: Compresses the sub-surface grain structure of parts to increase structural density and reduce part friction.Spindle Versatility: Suitable for production use across multiple machine platforms, including lathes, drill presses, machining centers, or automatics.Machine Alignment & CareAlignment Tolerances: Maximum rigid setup misalignment should never exceed 0.005 inches to prevent tool fatigue or mandrel tip stress.Rigid Spindle Locking: Must be combined with a keeper key or locking binding screw when used vertically to ensure zero axial drop.Chip Prevention: Best positioned in top tool-slides on multi-spindle automatics to minimize loose chip contamination from separate operations.Sourcing & Replacement PartsBecause Cogsdill legacy tool numbers vary by sizing series (e.g., standard 6408 or 6608 tool blocks), exact geometric parameters are tracked through the factory index. You can reference individual replacement components (tapered mandrels, cages, races, and individual precision rollers) through the Cogsdill US Burnishing Catalog
