Two new tool shank designs from Seco offer floating and adjustability for fully optimised, high-precision reaming operations. As an extension of the Precimaster Plus indexable-head reaming system, the new PMX-FL and PMX-AD shanks greatly improve hole surface finishes, eliminate runout and correct for misalignment without the need for special toolholders.
Seco’s new shanks incorporate compact internal systems for such functionalities, eliminating the need for special toolholders for floating and adjustability functions. Compared to special toolholders, the new shanks also situate reamers closer to machine spindle noses for less tool overhang.
Seco’s built-in floating system for static and turning-machine reaming applications is purely mechanical and much more stable than the common rubber or elastomere-type technology used on other similar tools. Also, the internal adjustment on Seco's new shank for rotating applications is mechanical in design and uses six screws to provide precise settings and effectively correct for spindle runout down to less than 0.005 mm.
