Composite Machining – a program for improved competitive performance and results
Machining solutions dedicated to specific composite materials as well as operations and demands are becoming an increasingly important competitive factor.
Sandvik Coromant offers tool solutions designed to improve the manufacturing process when machining composite and metallic stack materials in hand held, power feed and CNC machines.
The best solutions and support…
…are the success factors for today’s machining of composite components. Tool developments and customized designs, along with application support, play vital roles in finding the best answer to how components should be machined.
Sandvik Coromant and Precorp offer solutions and support from dedicated application specialists globally, along with application centers where research of composite materials and machining strategies are developed.

Obtaining quality in Composite Machining
Quality control along with achieving good security and productivity levels are the drivers in tool selection. Sandvik Coromant and Precorp diamond coated and PCD-vein technology drills have been developed as dedicated solutions to suit various material and set-up applications.
PCD vein, diamond coated and reamers have been designed with unique geometries developed for optimizing different applications such as the unique CoroDrill 859V PCD vein geometry.
For surface machining, the offer includes indexable milling cutters with diamond (PCD) inserts such as the CoroMill 590. CoroMill Plura, the range of products for edging includes coated carbide as well as diamond (PCD) tipped cutters with compression design. To remove fasteners, a collar cutter is available and helps to speed up repair work of aircraft structure.

Please give me more information on CoroDrill 850V, This is new and not for sale.
The Corodrill 859V is a Solid Carbide body with sintered PCD vein in the cutting area. The unique geometry of the 859V has been developed for composite materials where delamination is the primary concern, and has shown very promising results in several types of composite materials. It is not recommended for metallic stack materials. Primarily this geometry is targeted at CNC applications in CFRP materials.
It is not a standard product, but is available as an Engineered Special, made to the customer’s specifications. It is necessary to work with the local Coromant Representative in order to obtain this geometry, and typically would only be ordered after testing in the customer material (whenever possible) shows this to be the proper geometry.
