In order to process the workpiece reasonably and choose the milling cutter, it is necessary to analyze the shape, size, material hardness and other conditions of the workpiece.

The diamond dead centre is made of polycrystalline diamond materials, diamond is the hardest material on this planet and has very high thermal conductivity with very low friction. These three properties make diamond centres achieve outstanding performance when used to machine components, particularly when high production volumes and the very best quality are demanded. PCD (Poly-crystalline Diamond), is a solid, thick material with numerous grains of diamond connected in a metal matrix that is seamlessly joined on to the cemented carbide. The join is extremely robust and durable, preventing avoid downtime when machining workpieces and ensuring the highest quality.

Aviation structural parts have a wide variety and complex structure; in addition, because aviation structural parts are mostly thin-walled parts, the material removal rate is large, and the processing cycle is long, so the rapid delivery of aviation structural parts can bring greater economic benefits to aviation enterprises.
In order to reduce the weight and cost of the airframe, the aerospace industry usually uses composite materials and titanium alloys to manufacture the main parts of the airframe. Among them, titanium alloy is a difficult-to-process material with complex processing characteristics, which brings a series of challenges to manufacturers.

Vitrified bond is a widely used bond at present. Its performance is between the microbial metal bond and the resin bond, especially the ceramic bond in the vitrified bond diamond grinding wheel has the holes of the motorcycle, and has cooling, dust and dust retention. So it is not easy to block and burn during grinding, which satisfies the needs of material grinding and high-efficiency grinding. The evolution of the resin bond diamond grinding wheel solves the problem of the diamond grinding wheel. The problem of low life, low grinding efficiency, and easy deformation of abrasive tools during the grinding process.

In recent years, the development of cutting machine technology has continuously increased its spindle speed and feed rate, so that it can achieve rapid cutting with higher cutting speed, greater material removal rate, and higher precision. Tools like superhard materials put forward more demands. Only a few years ago, the spindle speed of some machine tools was only 6,000r/min, but now it has reached 30,000 to 40,000r/min, and the axis movement acceleration can reach 2G. With the support of powerful computer capabilities, this machine tool can realize the motion functions required for processing. In order to convert this speed advantage into a machining advantage at the point of action, it is necessary to use the corresponding tool material. However, if you use cemented carbide tools, the cutting speed can only reach 400m/min; while the cutting speed of PCD tools can reach as high as 3,000m/min. In addition to higher processing speeds, the main advantages of PCD and PCBN tools include longer tool life, and in most cases better surface quality, reduced tool changes, and reduced non-motorized man-hours.

The grinding wheel is a necessary tool for the grinding machine. To make the grinding wheel grind to an accurate size and smooth surface, it is necessary to prevent vibration during the grinding process. The structure of the grinding wheel is composed of a large number of unevenly distributed particles, and the inherent imbalance cannot be avoided, which will inevitably cause a certain eccentric vibration. The eccentricity of the grinding wheel installation, the uneven thickness of the grinding wheel, the imbalance of the spindle and the adsorption of the cooling liquid by the grinding wheel will increase the vibration.
