Machining Tungsten Carbide Coating

First class industrial coating services.

Machining tungsten carbide coating.

Wc is a chemical compound specifically a carbide containing equal parts of tungsten and carbon atoms. Tungsten carbide hvof diamond grinding turnkey roll processing since every thermal cold spray coating project is unique asb industries develops specific combinations of surfacing technologies and machining procedures to ensure optimal component and equipment performance. This coating holds its hardness at higher temperatures due to a layer of aluminum oxide that forms between the tool and the cutting chip. Tungsten carbide is the most widely used type of high speed machining hsm tool material produced by powder metallurgy consisting of hard carbide usually tungsten carbide wc particles and a softer metal bond.

One alternative to sourcing and machining in tungsten would be to use tungsten carbide coating. Premium machining has state of art machines and technologies specifically adapted to machining of tungsten carbide. 2 issue 10 from ore to insert. This layer transfers heat away from the tool and into the part or chip.

Today s machining world archive. Tungsten carbide chemical formula. In its most basic form tungsten carbide is a fine gray powder but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery cutting tools abrasives armor piercing shells and jewellery. With advanced equipment a skilled staff of thermal sprayers and machinists and extensive machining and grinding capabilities asb can provide unique thermal spray and cold spray solutions for extreme wear high temperature barriers and all encompassing part repair.

These coatings are produced by taking a powdered material in this case tungsten and heating them up and firing them out at extreme velocities where they liquify. I find you need a high positive cutting edge and the right carbide grade and coating mr. If there is vibration your tools will chip similarly the machine tool used to cut tungsten must be rigid and resistant to vibration he notes. Don graham turning products manager at seco tools inc.

Why is tungsten carbide an ideal tool material. Carbide tooling is generally run at higher speeds compared to hss. The tungsten carbide wc 12co coatings are resistant to sliding wear impact abrasion and fretting at temperatures up to 510 c 950 f preferably in non corrosive media. This makes tialn a preferred choice when coating carbide.

We will get back to you withing 24 hours. Formerly seco carboloy told the story of how tungsten ore is processed into tungsten carbide which then becomes a state of the art cutting tool insert.
