Kennametal showcases its TopSwiss MBS (Micro Boring Solid), which is designed to provide maximum accuracy when machining complex, small components for defense, medical, transportation, fluid transfer and small-parts machining applications. The TopSwiss MBS Medical Line (ML) inserts feature a specialized coating and sharp cutting edges for optimized surface finishes and reduced tool pressure, providing precision and biocompatibility for medical-grade applications. They are well suited for components like bone screws, tulip heads, dental implants and surgical instruments.

Specifically designed for machining materials such as stainless steel, titanium or cobalt chrome, the ML inserts feature the KCSM25S coating, which is said to provide a smooth, polished surface to reduce chip adhesion and improve component surface quality. Along with the coating, the inserts feature a specialized lead and relief angle that can withstand high tool pressure and has coolant delivered directly through the tool to the cutting edge to reduce heat and improve chip control.

For optimal performance, Kennametal recommends users pair the inserts with HP toolholders, which offer high precision and repeatability to centerline of ±5 μm, (±0.0002"). The HP toolholders are said to be user-friendly, featuring a specialized lock nut that requires only hand tightening for most applications; wrench tightening is required for applications that use high-pressure coolant of 70 bar or 1,000 psi and above.

Threading tools with the flexibility to thread a broad variety of holes provide the agility many shops need to stay competitive. They may be the only solution for many difficult materials.

This simple change to a Swiss-type turning machine’s toolpath can dramatically improve its ability to manage chips.

There are usually better solutions to chatter than just reducing the feed rate. Through vibration analysis, the chatter problem can be solved, enabling much higher metal removal rates, better quality and longer tool life.
