Seco Tools LLC has added a new range of taper-face toolholders to meet machinists’ increasing needs for higher production and process reliability. These new options provide two surfaces of contact to offer increased rigidity and consistency compared with standard holders when machining complex parts at high cutting parameters.
The new taper-face toolholders are designed for use with dual-contact spindle systems. They use plastic deformation of the machine spindle to achieve simultaneous fit of both the taper and the flange face from the holder to create a highly rigid connection and prevent the toolholder from being pulled into the machine spindle. This results in higher runout precision and better machining accuracy, according to the company. It also makes it possible for machinists to use higher machining parameters for substantial increases in productivity.
In addition to complex part machining, the taper-face toolholders excel in situations involving long tool overhangs, deep-hole boring and exotic workpiece materials that magnify cutting forces. They are available for spindle connections BT 30 TF, BT 40 TF, BT 50 TF, CAT 40 TF and CAT 50 TF in both metric and inch programs.

- boring
boring
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- plastic deformation
plastic deformation
Permanent (inelastic) distortion of metals under applied stresses that strain the material beyond its elastic limit.
- toolholder
toolholder
Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
