Carbide drawing die nibs for drawing ferrous and non-ferrous metal wires

A: Cemented carbide is a hard material used in machining tough materials such as carbon steel or stainless,

as well as in situations where other tools would wear away, such as high-quantity production runs.

Most of the time, carbide will leave a better finish on the part, and allow faster machining. Carbide tools can

also withstand higher temperatures than standard high speed steel tools.

Q: what your CNC inserts feature?

A:1. wear-resisting: useing GB class A cemented carbide mould core ,wire drawing dies mould core strength over 2200N/mm ³ ,do not crack
2. more wire rod can be drawed: the size area are 20% longer than common mould, which make sure our wire drawing dies can work longer!
3.our die do not get out of steel jacket easily: using advance cold bushing tech, and interference bushing craft, the wire drawing dies are tightening connect with the steel jacket.
4. fast delivery: all kinds of types are in stock, short producing period, we can delivery it to you within 4 days!

5. work eara are 20% longer, our tungsten carbide drawbench norm using life are double increaseed.

6. using top tungsten steel mold core with high strength, it hardness reach 92.5 degree.

7.if inner bore below 6.0, our wortle life is 25 tons ; if over 6.0, the wire drawing dies' life can be more than 100 tons

Q:what the CNC inserts grades and what the differents between each?

A:

Q:What are the key properties of cemented carbides I should be concerned with when selecting a grade for my application?

A: The key properties of cemented carbides that define their performance level for different applications include

abrasion resistance (directly related to the hardness of the grade), fracture strength, and fracture toughness.

In general, the abrasion resistance or hardness of any grade is inversely proportional to its fracture toughness.

Very often grade selection involves finding the best compromise between abrasion resistance and toughness.

In some instances strength and corrosion resistance can be important factors in the grade selection process.

Q: Which properties are important in metal cutting applications?

A: Depending upon the type of metalcutting operation (turning, milling, drilling, etc.), different combinations of

properties is needed in order to obtain optimum results. For example, in turning and drilling applications the

cutting tool is in continuous contact with the workpiece. Hence, for these applications, abrasion resistance and

strength are the most important properties to consider. However, in operations such as milling, which invariably

involve interrupted cutting, and hence high impact forces, toughness can be an important factor.

Grades employed for metalcutting applications are usually based on fine to medium hard phase grain sizes

(0.5 to 1.5 mm) and low to medium Co contents (6 to 15 wt.%).

Q: Which grades are useful in metal forming applications?

A: In contrast to metalcutting (where abrasion resistance and strength are of paramount importance),

cemented carbides used in metalforming applications will invariably be subject to high impact and shock forces.

Hence, grades used for metalforming applications must possess high toughness levels with adequate abrasion

resistance and strength. Grades employed for metalforming applications are typically based on coarse

grain sizes (3 to 8 mm) and high binder contents (15 to 30 wt. %).

Q: Which grades are useful in earth drilling or boring applications?

A: In many respects the characteristics of the grades employed for earth drilling and boring represent a

compromise between the characteristics that are important for metalcutting and those that are important

for metalforming applications. Grades for earth drilling and boring must possess the highest toughness

levels for any given abrasion resistance level, while simultaneously possessing adequate strength levels.

The best compromise is usually arrived at by using grades that are based on coarse grain sizes (3 to 8 mm)

and relatively low Co levels (6 to 16 wt. %).
