Diamond composite tooling problems

When a diamond cutter composites ( eg CFRP and GFRP), often due to the multi-phase characteristics of the workpiece material , resulting in the processing status is unknown. Composite materials are typically comprised of a substrate and the substrate is strengthened glass fibers or carbon fibers. Based on different application environments , you can use a variety of highly resistant fibers. The choice of fiber depends on the needs of the end product .
   When cutting the fibers , the transverse and longitudinal fibers not interfere with each other , causing the serrated cutting edge of a workpiece is easy to produce , delamination and fiber damage. High impedance of the tool will result in a strong fiber abrasive wear , which requires the tool material with high hardness.
   Thermal stability of the composite cementitious material is not very good . Processing , composite materials and cutting diamond tools materials will react . Therefore , in order to avoid chemical damage of the workpiece , the cutting is usually to limit the cutting speed. A variety of standard machining composite materials has not yet worked out, such as surface quality of the workpiece quality standards , waste discharge machining based and so on.
   Difficult to process and its structural characteristics of multiphase composites , and so have a wide variety of needs in the processing tool material . If you need a very sharp cutting edges when cutting fiber , we can choose CVD diamond material or lined with PCD tools.
   However , the contour of the use of such material can be processed is limited, especially when the contour of the workpiece to be machined is very complex, difficult to achieve. In some cases, when you need chipbreakers must use carbide tools . To reduce serious carbide abrasive grains may occur in the processing of the composite wear may be appropriate to increase the hard diamond cutter diamond coating . However , an effective method of cutting the composite material which is not widely used solution .
