Why Use Tungsten Carbide？

Tungsten carbide (WC) is an inorganic chemical compound containing equal parts of tungsten and carbon atoms. In its most basic form, it is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, tools,abrasives, as well as. Tungsten carbide is approximately three times stiffer than steel, and is much denser than steel or titanium. It is comparable with corundum in hardness and can only be polished and finished with abrasives of superior hardness such assilicon carbide, cubic boron nitride and.

The Common Drill Bit

Common home repair drill bits are made of steel or High Speed Steel (HSS). Although inexpensive, common steel drill bits tend to wear out or break very quickly. HSS drill bits last longer than steel, but are more expensive. These types of drill bits are most effective when used on wood, drywall or plastics.

The Application of Tungsten Carbide End Mill

Tungsten carbide end mill is used for milling, with one or more of the rotary tool cutter.The margin in workpiece is cut by the mill intermittently. Carbide end mill is mainly used in processing plane, steps, grooves, forming the workpiece surface and cutting and so on. There are two common materials for manufacturing end mill: high-speed steel, and tungsten carbide. Carbide end mill has relatively higher hardness, stronger cutting ability, and can improve the speed and feed rate as well as increasing productivity.

When to Use a Carbide Drill Bit

Tungsten carbide drill bits undergo a lot of stress when drilling a hole. The high-speed rotation of drill bits generates friction that, in turn, generates heat. The friction between drill bit and material leaves drill bits slightly duller after each use. The heating and cooling of the drill bit material can weaken the internal structure of the bit over time.

The development history of PCD drill

Tungsten carbide PCD drill was developed by PrecorpInc in Utah in American.The trade mark DiaEdge of PCD drill was owned by this company. Since 1980s,metal cutting began to be used,but it didn't establish credibility in the minds of people.Nowadays,the PCD drill processed by high temperature and high pressure sintering gets people's attention again and the scope of its application is also widely expanded.

Characteristics and application of tungsten carbide drilling machine

Characteristics and application of tungsten carbide drilling machine

(1)Suitable for the drilling of more complex material at high speed.

(2)Selecting high-performance alloy blade, effectively reduce the collapse, good wear resistance.

(3)Multilayer geometry cutting end edge to enhance the excretion of performance, to maintain a smaller cutting resistance.

Tungsten Carbide Rollers

Paraffine process and spray drying tower are used to make the first class material for making rolls.Various specifications of rolls with better microstructure, performance and dimension accuracy are supplied.
