The mature application of carbide cutting tools in aerospace manufacturing

Composite materials with light mass, high strength, high temperature resistance, corrosion resistance and other properties, is an ideal material in the field of aerospace. With the widely application of the aerospace composites, the correct selection and reasonable use high quality machining become the key tool efficiently.Commonly used at present,the aerospace manufacturing tool materials mainly include hard alloy, superhard cutting tool materials and ceramic, etc., among them, the carbide and accounted for the largest superhard cutting tool materials, has become the leading in the development of aerospace cutter knives, wide range of applications. Super-hard material cutting tool (PCD) and carbide cutting tools has been maturely applied in aerospace manufacturing.

 

PCD cutting tools and carbide cutting tools with sharp cutting edges of fine grinding, widely used in aerospace field of carbon fiber reinforced materials (CFRP) and glass fiber reinforced materials (GFRP) and aluminum silicon carbide (SiCp/Al) composite material has excellent effect on processing, can effectively solve the composite material processing in the process of material defects such as delamination, tearing, burr, at the same time, to be precise and smooth cutting effect for higher machining efficiency, better wear resistance, longer tool life.

 

In the process of aerospace composite materials processing, parts machining and milling, slotting machining difficulty, therefore, PCD and carbide was developed according to the high performance machining tool and cutter, are mature tool at present.

 

Drilling is especially common in the manufacturing process of carbon fiber composite materials important working procedure. Hole on the composite materials processing, material burns, poor quality of processing surface, appear easily defects such as delamination, tear and collapse. 8 side milling machining carbide cutting tools of twist drill with 8 surface of blade design, so as to reduce the cutting force of the drill out material, avoid stratification; Drilling has a special drill point form, drilling axial force is small, sharp blade to ensure the good quality of hole; PCD diamond blade durable economic nest degree is high, the surface roughness index of stability, precision grade 2 a thread and cone coordination, to ensure the high precision, quick change bit 100 ° and 130 ° Angle of dimpling metric, American standard tools all specifications and delivery; Drilling and reaming economic integration tools can be a one-time drilling and economic, omitted by conventional drilling and reaming process needed to recede cutter, tool change and tool inversion, can greatly shorten the processing time, repair the light blade with on hole wall burnishing effect.
