Heule Spot Facing, Counterboring Tool Provides Flexible Machining

Heule Precision Tools introduces Solo L tooling for spot facing and counterboring projects over 25 mm. Front and back counterbores up to 1.95-times bore diameter can be produced in bores ranging from 25.0 - 45.0 mm in diameter.

Solo L features a simple, reliable design which functions without an anti-rotation device, change in spindle rotation, coolant pressure or contact mechanism. This sealed system prevents coolant contamination, and the pin-driven cutting blade, which moves in and out radially, prevents chips from jamming the system. Solo L is designed to be customizable, with the tool’s blade housing, blade control and blades individually designed to meet specific project requirements. This specialized system cuts interruptions and difficult materials like nickel, titanium and other exotic alloys, making it well suited for a wide range of CNC, transfer, multi-spindle and conventional machining applications.

The Solo L uses two centrifugal weights installed in a sealed tool head. With an activation speed rate of 1,600 rpm or higher, the weights start moving outwards and turn the gearwheel, which drives the blade out by rotating the blade control. When the spindle is stopped and then actuated to cutting speeds, a pullback spring pushes the centrifugal weights back to the center and the blade extends to the cutting diameter. Maximum machining speed is 900 rpm.

In addition to the L model, three other Solo models are available, each is capable of counterboring two times the bore diameter minus 1 mm. Possible applications up to 40 mm through hole depending on the counterbore to bore ration and parameters. In most cases through-coolant is optional, with a 280-psi maximum.
