SMW Autoblok’s spindle speed increasing live tools for Haas lathes are low-profile live tools that feature a 1-to-3 speed increasing ratio and a maximum speed of 12,000 rpm.

Designed to increase the performance of Haas lathes with 4,000-rpm driven turrets, the live tools can reduce cycle times and duty cycles, particularly in finishing applications of mild steels, aluminum, plastics and reinforced resins. With a low profile of 88.5 mm (3.48”), these new tools are no taller than a standard live tool, preserving Z-axis clearance for workholding and parts. Additionally, with their minimal width of 80 mm (3.15”), they do not interfere with adjacent tools in the turret.

The live tools use square drive, Gleason matched ground helical gears for improved torque transmission, and high quality twin interlocking labyrinth seals to prevent contamination from coolant and chips. The ER clamping design makes for easy tool changes, higher clamping forces, extended drill lengths and improved rigidity, the company says.
