Mature application of Zheng Drill PCD tool and carbide tool in aerospace composite processing

Compared with other materials, composite materials have the characteristics of light weight, high strength, high temperature resistance and corrosion resistance, making them ideal materials for aerospace applications. With the wide application of aerospace composite materials, how to correctly select and use tools reasonably for high-quality and high-quality machining is a very important issue. At present, the tool materials widely used in the aerospace industry mainly include cemented carbide, super-hard tool materials and ceramics. Among them, cemented carbide and super-hard tool materials account for the largest proportion, and in today's aerospace manufacturing, both become aviation. The leading tool in the development of aerospace tools has a wide range of applications. PCD's superhard material tools and carbide tools developed by Zheng Drill have been used in aerospace manufacturing and processing.
Zheng Drill PCD tools and carbide tools have sharp-edged sharp cutting edges for composites of carbon fiber reinforced materials (CFRP), glass fiber reinforced materials (GFRP) and aluminum-based silicon carbide (SiCp/AI), which are widely used in the aerospace industry. The material processing effect is excellent, which effectively solves the defects such as delamination, tearing and burr of the material during the processing of the composite material, and achieves higher precision and better wear resistance while obtaining precise and smooth cutting effect. Tool life is longer.
Hole machining and milling and milling of parts in aerospace composites are difficult to process. Therefore, Zheng Diamond has developed high-performance hole machining tools and milling cutters made of PCD and carbide. Maturely used in aerospace composite processing.
Drilling is an important process that is common in composite materials, especially in carbon fiber processing. Hole processing on composite materials is prone to defects such as material burns, poor surface quality, delamination, tearing and collapse. The 8-sided edge twist drill in Zheng drilling tool, 8-sided blade design, to reduce the cutting force when the bit is pulled away from the material, to avoid stratification; the cone drill has a special drill tip form, the drilling axial force is small, The sharp edge guarantees the good quality of the hole; the PCD boring drill, the PCD cutting edge has high durability, the surface roughness index is good, the precision grade 2A thread and the taper surface match, ensuring high precision and quick and easy replacement of the drill bit, 100° And the 130° boring angle of the metric and American standard tools are available in full specifications; the drill reamer integrated tool, the drilling and the armpit are completed at one time, omitting the retraction, tool change and the need for machining with conventional drills and reamers. The tool index can greatly shorten the processing time, and the polishing edge belt can squeeze the hole wall.
Among the newly developed milling cutters, the composite milling cutter A/B/C is used for coarse and fine carbon fiber composites (CFRP) and glass fiber composites (GFRP). The upper and lower cutting edges effectively suppress delamination and burrs. For insert milling and side milling; KEVLAR material milling cutters, specially designed for KEVLAR materials, which cut the fibers very well, avoiding delamination and material delamination; two-blade PCD end mills (thick), The PCD sharp cutting edge cuts the fiber material lightly, with smaller cutting forces, longer tool life and better surface quality. Center cutting allows for plunge milling and finishing on the plane. In addition, there are single-blade PCD end mills, PCD end mills, two-blade PCD ball-end milling cutters, single-crystal end mills, etc., which have excellent cutting results for composite materials.
At present, the composite materials widely used in the aerospace field mainly include resin-based composite materials, metal-based composite materials, carbon-based composite materials and ceramic-based composite materials. For different composite materials processing workpieces, Zheng Diamond provides customers with tool configuration solutions. Continuously update and improve to help customers improve the economics of processing more effectively
