Minimax AD 21

The Minimax AD 21 is a semi-automatic multi-spindle boring machine designed to perform simultaneous drilling and boring operations across wooden panels with high repeatability. As a 21-spindle drilling head system, it executes multiple hole patterns in a single pass, eliminating sequential drilling steps and significantly reducing cycle time for panel-based woodworking operations.

The machine's technical foundation centers on 21 independently positioned spindles with 32mm center-to-center spacing, each capable of rotating at 2800 rpm and accommodating tools up to 40mm in diameter. This fixed spindle configuration enables consistent, repeatable multi-point drilling patterns across panels up to 833mm in width, with workpiece height adjustability between 10–85mm. The 905 x 372mm worktable provides stable support for standard cabinet components, frameless panel systems, and solid wood components requiring precision hole alignment.

The AD 21 is engineered for professional woodworking workshops and mid-scale manufacturers producing cabinet frames, case components, knock-down furniture assemblies, and modular panel systems. It bridges the gap between manual boring operations and fully automated CNC systems, offering the speed and consistency demanded by production-oriented craftsmen without the capital investment or floor space requirements of larger multi-axis machines. The fixed spindle spacing of 32mm accommodates European 32mm system standards commonly used in modern cabinetry and modular furniture design.

Within the category of multi-spindle boring machines, the AD 21 occupies a practical middle ground: simpler operation and lower cost than adjustable-spindle or CNC-driven systems, yet dramatically faster throughput than single-head drilling for shops processing 50+ panels daily.
