Manual tool setting fixture for large-diameter precision tools

MAPAL presented the UNISET-V basic plus, a manual tool setting fixture designed for precise adjustment of large-diameter cutting tools. Positioned between basic mechanical solutions and fully automated CNC systems, the device addresses precision and cost-efficiency requirements in industrial machining, particularly for small and medium-sized enterprises.

Positioning between mechanical and CNC setting systems
Tool presetting plays a critical role in achieving process stability and machining accuracy, especially in sectors such as automotive manufacturing and electromobility, where large tools are used to machine components like stator housings. Many manufacturers lack suitable presetting solutions capable of handling heavy tools while maintaining micrometre-level precision. Existing mechanical devices may reach performance limits with larger tool dimensions, while CNC presetting machines can exceed the investment capacity of smaller companies.

The UNISET-V basic plus is designed to bridge this gap by combining manual operation with high mechanical stability and precise adjustment capabilities. The system aims to deliver repeatable accuracy without the complexity or cost associated with fully automated CNC presetting platforms.

Technical design for heavy-duty precision
The UNISET-V basic plus supports guide pad tools with diameters ranging from 100 to 400 mm, a maximum measuring length of 750 mm, and tool weights up to 45 kg. Standard spindle interfaces include HSK63, HSK100, and SK50, with reducing adapters enabling compatibility from HSK32 to HSK80.

A welded steel housing provides mechanical rigidity, ensuring stable measurement conditions even when handling large or heavy tools. The bench-top unit measures approximately 1.3 metres in height and weighs 179 kg, allowing installation directly in production environments without requiring a dedicated presetting room. This enables operators to position the system close to machining centers, reducing setup time and workflow complexity.

Precision adjustment for reaming and fine boring tools
The fixture enables micrometre-accurate setting of cutting edge overhang and back taper, which is particularly important for guide pad technologies used in reaming and fine boring applications. Operation follows a two-button principle, allowing precise adjustment of the cutting edge via the guide pad while maintaining simple handling.




Application scope and industrial relevance
The UNISET-V basic plus targets small and medium-sized manufacturers seeking precise presetting capabilities without investing in CNC-based systems. It also supports larger companies requiring reliable and repeatable adjustment of large-diameter tools in demanding production environments.

Typical application areas include automotive production, electromobility component machining, and general precision manufacturing where process reliability and dimensional accuracy are critical.

Technical overview
Designed as a vertical bench-top device, the UNISET-V basic plus complements MAPAL’s existing presetting portfolio, filling the gap between entry-level mechanical solutions and advanced expert systems. Key specifications include a diameter range of 100–400 mm, measuring length up to 750 mm, and modular configuration options enabling adaptation to different production requirements.
