Clamping method enables cutting inserts to be held in place with more force, which, in turn, makes the entire system more rigid and results in higher repeatability.

Horn’s tension wedge clamping method for its Supermini system (which has 105 precision carbide tools) is designed to improve overall system repeatability. The clamping design uses a tension wedge on the face, rather than a retention screw on the circumference. This enables the cutting insert to be held in place with more force, which, in turn, makes the entire system more rigid. The company says that the improved rigidity results in a higher level of repeatability when changing inserts and also enables better use of available space. When working with Swiss-type lathes, the clamping method enables users to change the insert without removing the toolholder.

The Horn Supermini system can bore holes from 0.2 mm [0.0078"] to 8 mm [0.3149"] in diameter. According to the company, over 1,500 varieties are available as standard. The wedge clamp is also designed to work with applications in grooving, chamfering, threading, drilling, boring, back boring and face grooving. Standard cutting geometries, substrates and coatings are available for a variety of applications and materials. Many standard substrate coating and geometry combinations are also available to match these applications and materials
