FAQ

Is the used YASDA YBM-8120V suitable for precision mold and die machining?

Yes. The YASDA YBM-8120V is designed for precision jig boring and milling applications, making it suitable for consideration in mold base machining, precision tooling, die components, and complex mechanical parts. However, final suitability depends on the actual machine condition and the required machining tolerances.

What is the spindle speed of the YASDA YBM-8120V CNC jig borer?

The available seller specifications report a maximum spindle speed of 20,000 RPM. However, YBM-8120V machines have been supplied in different configurations, so the exact spindle specification of this used unit should be verified before purchase.

How accurate is this used YASDA YBM-8120V?

Historical Renishaw ballbar records report circularity values of 4.3 μm in XY, 7.9 μm in ZX, and 10.1 μm in YZ. These figures describe circular interpolation behavior under specific test conditions. They do not establish the machine's current positioning accuracy or guarantee finished-part tolerances.
