FAQ

What types of precision machining can this ROKU-ROKU machine perform?

The machine is intended for micro-milling, fine-detail machining, small-diameter drilling, and precision mold manufacturing. Potential applications include miniature mechanical parts, electronic component tooling, optical instrument components, and precision mold inserts. Actual machining capability depends on the material, tooling, and required tolerances.

What spindle speed and CNC control system does this machine use?

The machine has a reported maximum spindle speed of 40,000 RPM and is equipped with a FANUC Series 31i-MODEL A CNC controller. The seller also reports linear motor drive technology and a 50-tool magazine. The spindle specification and auxiliary equipment should be confirmed during technical inspection.

How accurate is this used ROKU-ROKU precision machining center?

A historical Renishaw QC20-W ballbar test recorded an XY circularity deviation of 5.8 μm at a test radius of 100 mm and feed rate of 1,000 mm/min. This result reflects contouring performance under the recorded conditions rather than a guaranteed machining tolerance. Current accuracy should be verified through inspection or additional testing.
