Machine performance was once linked to the size and cost. However, the Haas Mini Mill Series challenged this theory by offering 40-taper performance in a compact design at unprecedented prices. Building on this success, Norwich-based Haas Automation Ltd will unveil a completely redesigned Mini Mill Series delivering enhanced capabilities and value at MACH 2024.

The upgraded Haas Mini Mills inherit features and options from the larger Haas VF Series while maintaining a smaller footprint and the latest models feature an expanded work envelope, of up to 406 x 356 x 381mm. The Mini Mill Series are manufactured at Haas Automation’s US facility in California, using 40-taper spindle shafts similar to those in the VF Series. With spindle speeds ranging from 8,000rev/min in the standard Mini Mill to an optional 15,000rev/min in the Super Mini Mill, users can adjust performance according to their needs.

Efficiency is key in manufacturing, and Haas acknowledges this with its Wireless Intuitive Probing System (WIPS). Integrated into the Haas Control interface, WIPS speeds up setup and facilitates probing routines, minimising downtime. Productivity and precision can be enhanced by adding Haas indexers, rotary tables, or tilting rotary accessories to a Mini Mill. With straightforward installation and on-screen instructions, enabling fourth- or fifth-axis capability is easy.

Responding to user demands, the new Super Mini Mills Series comes with a high-speed 30+1 side-mount tool changer as standard, and the machines feature a 10-station carousel tool changer, with an optional 20-station variant. Crafted in-house, every tool changer undergoes rigorous quality control.

Recognising the importance of effective chip and coolant management, the new Mini Mill and Super Mini Mill models come equipped with a 40-gallon (151 L) rollaway coolant tank as standard. Various chip and coolant management solutions are available to meet specific needs.
