Historical Mazak QT-20 specifications organized by year and configuration from machines represented in the UMS database.
Historical specification information — not a machine-for-sale listing. These values come from individual UMS machinery records. Specifications can vary by year, control, configuration and optional equipment.

QT-20 vs. Quick-Turn 20
UMS preserves QT-20 and Quick-Turn 20 as separate historical model designations. The database shows materially different specifications and generations under those names, so this page does not automatically combine them.
