Mini Lathe Roller Burnishing Tool For Rock Solid Slick Surface Finish On Steel Brass And Aluminum With Hella Durable Steel Balls And Polishing Cloth Fits Conventional And Cnc Lathes Hrc18 To 68 Hardness

Single Unit CNC Lathe Roller Tool for Smooth Metal Polish
✔️ 20x20 mm (3/4 inch) mount, 135 mm (5.3 inch) long, finishes steel

This handy roller unit mounts straight into standard tool posts on conventional and CNC mini lathes to scrub out machining marks during turning. You get one diamond coated conditioning head in the box plus a soft wiping rag to keep grease off your raw stock before running numbers.

✅ Diamond impregnated roller bearings press uniform pressure to stop scratches and uneven patches across turned surfaces
✅ Powder coated rust resistant body shields internal springs against flood coolant splash and sharp metal chips
✅ Handles mirror grade roughness ratings under 0.2 micrometers for factory level results without dragging extra grinding passes
✅ Compatible with aluminum alloys, pure copper, brass, and heat treated steels ranging from soft stock to fully hardened plates up to HRC 68

💡 How does a rotary roller burnishing tool improve surface roughness compared to traditional abrasive grinding?
Burnishing reshapes micro peaks directly on the workpiece rather than tearing material away, which keeps dimensional tolerances tight and cuts down downtime during batch production.
- Dense chromium steel cores push hardened balls along the cut groove to flatten peaks faster than standard sanding belts
- Rolling friction slams the outer material flat without shaving off raw stock, which saves you cash on replacement tooling
- Cutting dry works perfectly well since the method locks in workshop oil and stops fine grit from flying around the shop floor
