SUMIDIA BINDERLESS (NPD10) Small Diameter Boring Bars

DABX Series

Recommended Work Material

Movie

Feature

Ideal for high-precision machining of small diameters (ø3mm and up)

Switching from electrical discharge machining to cutting reduces machining time and total costs

Superior wear resistance maintains cutting edge sharpness for a long time

Wear resistance evaluation on cemented carbide (88HRA)

Minimal wear even after cutting distance of 4,000m

Utilising cutting to reduce machining time and total costs

Switch from electrical discharge machining (EDM) to cutting

Switching from EDM to cutting - Surface roughness of cutting: Rz1.3μm, against Surface roughness of EDM: Rz7.0μm, thus Shortening time for polishing (Rz0.3μm)
Achieving 2.5x higher machining efficiency with 25% total cost reduction.
