LEUCO Telcon (Villa Rica, GA, US) is emphasizing its line of tools for drilling, countersinking, milling and routing operations. These include:
- DVT (Diamond Vacuum Technology) for the manufacture of high-quality, abrasive diamond tools to mill and grind carbon fiber composites, fiberglass composites, ceramics and refractory materials. Vacuum brazing creates a stronger grit bond (compared to nickel plating) resulting in substantially longer cut life. DVT tools are available with either synthetic or natural diamond grit and can be dressed to precise tolerances. DVT is offered in a variety of tool formats with optional axial and or radial coolant holes.
- Helicon PCD Full Nib Spiral Drills for CFRP, CFRP/aluminum and CFRP/titanium stacks. The solid PCD (polycrystalline diamond) nib allows fully fluted and raked point geometries similar to solid carbide but in a super abrasive material for longer cut life. Helicon drills are available with coolant holes starting at 4.85 mm diameter and larger. Helicon drill counter-sinks are also available with smooth or threaded shanks for most automatic machines.
- P-System PCD- (polycrystalline diamond) tipped end mills for high-speed machining of honeycomb core blanket and composite sandwich panels. The patented 70° helix slices Nomex and Kevlar cores while compression geometry prevents top and bottom panel delamination. The diamond cutting flutes completely encircle the diameter of the tool resulting in minimal impact forces and extreme long edge life. Up to 2000 ipm of feed with a 25-mm diameter tool is possible.
- RX CVD diamond-coated tools for aerospace composites, made via a nano-crystalline, multilayer layer process that offers nearly 10,000 Vickers. Most carbide tooling formats are available to include drills, drill counter-sinks, reamers and end mills.
Editor PickComposites in the Martian suit
When humans do finally travel to Mars, they will have to be well protected from a less-than-hospitable environment. The suit designed to do the job is already in development at NASA, and it relies heavily on composites.
