Tungsten Carbide Machining

Machining of Tungsten Carbide
PREMIUM MACHINING is specialized in the machining of cemented carbides(Tungsten Carbide) tools and custom parts, this super hard material is usually used for metal molds, cutting machines,  industrial machinery, cutting tools, armor-piercing rounds, other tools and instruments.

Methods of Cemented Carbide Machining:
Because of its extremely high hardness,Tungsten carbide can not be machined by traditional machining process such as turning, milling or drilling. Even Tungsten Carbide can be machined by special tools like PCD tools, CNB tools and Ceramic Tools, but these cutting tools lose the sharpness easily. So in PREMIUM MACHINING we tend to grind Tungsten Carbide with diamond tools or machine Tungsten Carbide by electrical discharge machining(EDM), micro-EDM or by ultra precision wire EDM.PREMIUM MACHINING has state of art machines and technologies specifically adapted to machining of Tungsten carbide.

If you have need to make Tungsten Carbide tools or parts, please send 3D&2D drawings to quote@premachining.com for evaluation and quotation. We will get back to you withing 24 hours.

The Cemented carbides(also called Tungsten Carbide)are a range of composite materials, which consist of hard carbide particles bonded together by a metallic binder cobalt (Co). Cemented carbides commonly use tungsten carbide (WC),titanium carbide (TiC), tantalum carbide (TaC) or niobium carbide (NbC) as the aggregate.Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites. It is mainly used to make high speed cutting tools,cold working molds, measuring tools and high wear resistant parts.

Advantages of Tungsten Carbide Materials:
(1) High hardness,High wear resistance and High Red Hardness
The hardness of cemented carbide at room temperature can reach 86~93HRA, equivalent to 69~81HRC.In 900 ~ 1000 ℃ can keep still keep high hardness, and has excellent wear resistance.Compared with high-speed tool steel, cutting speed can be 4~7 times higher, life 5~80 times longer, can cut hard materials which hardness up to 50HRC.

(2) High Strength and Elastic Modulus
The compressive strength of cemented carbide is up to 6000MPa, and its elastic modulus is (4~7) 105MPa, both higher than that of high-speed steel.But its bending strength is low, generally 1000~3000MPa.

(3) Good corrosion resistance and oxidation resistance
Generally, it can resist corrosion of atmosphere, acid and alkali, and is not easy to oxidize.

(4) small linear expansion coefficient
Stable shape and size when working.

Cemented carbide with high hardness, strength, abrasion resistance and corrosion resistance, known as the "industry teeth" ,used in the manufacture of cutting tool, cutting tool, cobalt and wear-resistant parts. Some key areas where cemented carbide components are used:
1. Military
2. Aviation
3. Machinery
4. Metallurgy
5. Oil Drilling
6. Mining Tools
7. Electronic communications
8. Construction and other fields
This category contains a countless number of applications, but can be split into three main areas:
• Engineered components
• Wear parts
• Tools and tool blanks
