Cemented carbides have been widely applied in cutting tools and wear-resistant components due to their ultrahigh hardness and good wear resistance. However, the disadvantages of limited impact toughness and high cost have restricted their further application. Consequently, cemented carbides are usually joining with ductile steels to combine the advantages of both. Among various materials joining technologies, brazing have been an effective method to achieve high quality dissimilar cemented carbide joints. In this paper, the research status of cemented carbide brazing is reviewed. The materials utilized as brazing filler metal in cemented carbide brazing joints are summarized in detail. Researchers have done lots of works utilizing Cu based and Ag based brazing filler metals which are the most commonly used interlayers in brazed joints of cemented carbide and ductile steel. The effects of different filler metal on wettability, microstructure, phase constitution and mechanical properties of brazed cemented carbides joints are analysed. Besides, a series of newly developed brazing filler material such as nickel-based high temperature brazing filler metal, amorphous brazing filler metal and high entropy alloy brazing filler materials are also involved. These newly developed brazing filler metals have shown great potential in fabricating high quality joints. Finally, the current issues of cemented carbide brazing are reviewed and the develop trend is predicted.

Historically, hardened parts were often ground as many cutting tools could not stand up to the rigorous demands of materials with high hardness. Today, many companies are switching from grinding operations to hard turning, as the benefits are numerous.

The sintered CBN blank is cut into desired shapes which are brazed onto cemented carbide blanks in the form of ISO standard geometries; these are final CBN, single or multiple corner inserts.How precision machining is affecting the future state of medical devices
Precision machining is found in a variety of sectors, including electronics, aircraft, and healthcare. CNC machines are used to make a lot of medical components and devices. The medical equipment industry consists of various medical parts, such as implants for spine reconstruction, knee, and hip replacements, etc.

In an industry where mistakes lead to serious injuries or even death, the machining process of medical parts must be extremely precise. In addition to manufacturing complying with ISO 9001 quality management obligations, medical components and devices must comply with other higher standards.

The advantages of precision machining in the medical industry
Thanks to precision engineering, we can experience many medical breakthroughs today that would not be possible if not for the new and improved technology and products brought about by the developments and innovations of this field. Take a look at some ways precision machining affects your health and how it will continue to advance the state of medicine in the future.

Machining meets the most stringent tolerances

In the medical industry, accuracy is of the utmost importance. One aspect that contributes to surgical success is a tool that fits perfectly into a surgeon's hand. However, precision machining is not limited to surgical instruments. It helps construct robotic arms and other devices used in surgeries to perform complex operations which were unthinkable even ten years ago - such as breast augmentations or microsurgeries on embryos without harming the mother.
