M14 / M10 Shank Vacuum Brazed Dry Drilling Diamond Core Drill Bit

Founded in 2000, Twin-Town Enterprises has been relentlessly pursuing excellence and become a leading manufacturer dedicated to productions of abrasive & super-abrasive, TCT saw blade and brazed diamond tools.

In 2004, Twin-Town Saw Industries Co., Ltd. was founded to focus on producing tungsten carbide & cermet tipped saw blade.

In 2012, after a strategic partnership was formed with NUAA, Twin-Town Saw Industries established a new department to produce all kinds of brazed diamond & CBN tools.

Meanwhile, Twin-Town also secured a series of patents and has become a certified National High-Tech Enterprise, a prestigious honor granted by the Chinese government.

Today, Twin-Town continues to pledge to pursue excellence through endless efforts to innovate, to control quality, to work closely with our customers as partners, and to make them more competitive and successful.

 Q: What is brazing Technology?

 A: Brazing is metal-joining process whereby a filler metal is heated above melting point and distributed between two  or more close-fitting parts by capilary action. The filler metal is brought slightly above its melting (liquidus) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (known as wetting) and is then cooled to join the workpieces together.

Q: What is the difference among brazing technology, sintering technology and electroplating technology?

A: During brazing process, welding solder combines parent metals together at a welding temperature lower than parent metal's melting temperature.

Obviously, brazing can chemically bond diamond grits and steel matrix, but electroplating & sintering can only mechanially "hold" diamond grits.

Q: Why should you choose brazing over sintering & electroplating?

A:  Higher bonding strength leading to longer life.

     Optimum exposure rate leading to higher cutting speed.

     Well-adaptable to different materials and wide scope of application.

     More environmentally friendly both in producing and using process, leading to a green future.

Brazing, this innovative technology, enables new applications which conventional techniques cannot. It significantly enhances product performance.
