The increasing application of composite materials in the aviation industry has presented various new challenges to metal cutting manufacturers. Carbon fiber reinforced plastic (CFRP) is one of the most difficult composite materials to process. The material is coated with materials with different physical properties in different layers to give it high hardness, high toughness and high strength. As a result, the material is very wear-resistant and difficult to process.

The tool life of carbon fiber reinforced plastics (CFRP) is very short due to the harsh and harsh cutting environment. Because the exact materials used in different layers of this material are not known, it is difficult to design a matching tool. When processing composite materials such as CFRP, it is impossible to talk about chip production. On the contrary, the removal mechanism of the material is described as crushing may be more appropriate. The impact of the cutting edge of the tool breaks the hard carbon fiber, rather than cutting the material. This process causes severe wear and tear on the cutting edge, which leads to rapid tool failure.

As with other machining applications of cutting tools, the geometric shape of cutting tool is the decisive factor of cutting performance in the processing of composite materials. However, in the field of composite materials processing, tool materials also play an important role in determining tool performance. If the tool material cannot withstand severe abrasion well to maintain its geometric shape and cutting edge sharpness, the tool will wear quickly and the precision level of the tool geometry will be reduced rapidly.

A new type of solid carbide end mills with a specially constructed cutting edge at the esca front is designed to achieve high efficiency machining of CFRP composite materials. To ensure the successful processing of CFRP, iska released a high quality, sharp cutting edge integral carbide endmill based on the mature alloy brand IC02. Isca is also able to coat these wear-resistant tools with diamond to meet customer needs, providing a longer life IC2012 brand.

The investment of clamping fixture is usually considerable. In order to obtain clean and sharp cutting without pilling, layering or tearing, the workpiece needs to be securely clamped to resist vibration.

The integral carbide end milling cutter at isca front has a unique cutting edge and is designed for high efficiency cutting of carbon fiber reinforced plastics (CFRP). Advanced EPND and EPNC end mills have cutting edges specially designed for processing carbon fiber reinforced plastic (CFRP) parts. Cutting edge tools can transfer cutting heat efficiently, achieve high speed feed and cutting speed, and achieve impressive material removal rate and very economical processing cost. The brand name of hard non-coated superfine alloy IC02 is adopted, or diamond coating is required.

EPND drilling and milling cutter (rough milling) with 140 degrees Angle of front tooth cutting edge and unique ribbed, produce low cutting force, can achieve high cutting parameters. The diameter range of EPND vertical milling cutter is 1.6-12mm, with 6, 8 and 10 chip removal grooves. In many cases, isca's new drilling and milling solution eliminates the fracture of CFRP carbon fibers and greatly reduces layering.

EPNC rough milling cutter used for processing carbon fiber reinforced plastics (CFRP) has unique edge-shaped teeth on the cutting edge, which generates low cutting force and can achieve high cutting parameters. EPNC rough solid carbide end mills with a diameter of 8,10 and 12mm, with 10 chip removal grooves.
