Tungsten carbide cutting tool regrinding is commonly seen currently. The price for tool regrinding is much less than that of a completely new tool, and it can effectively extend the tool service life. Regrinding is usually conducted in some special or expensive cutting tools. Tools that can be reground include drills, milling cutters, hobs, and so on.
In the drill or milling cutter regrinding process, cutting edge should be ground in order to remove the original coating, and therefore grinding wheel used must be hard enough. The pretreatment towards cutting edge is critical in tungsten carbide cutting tool regrinding, because the geometrical shape of cutting edge must be completely and accurately the same as the original one. Therefore, unreasonable grinding process should be avoided (for example: coarse or dry grinding that may damage cutting edge surface by high temperature).

Currently, tungsten carbide is the major material for producing threaded milling cutters. High-speed steel screw tap’s processing line speed is only about 10 ~ 30m / min, while that of tungsten carbide threaded milling cutter reaches 80 ~ 200m / min. Therefore, the latter is obviously more suitable for high-speed cutting, and the surface roughness of threads processed by it is also greatly improved.
High-speed steel screws used for machining of high hardness materials and high temperature alloys, such as titanium and nickel-based alloys always have short service life. However, this problem can be well solved by adopting tungsten carbide threaded milling cutter as machining tools, because it possesses hardness up to HRC58 ~ 62. What is more, more than one screw taps will be needed to process threads with the same thread pitch but different diameters, but if it is processed by tungsten carbide threaded milling cutters, only one will be enough.When thread tap wears, it cannot be used again, but this will not happen to tungsten carbide treaded milling cutter because its cutter radius compensation adjustment can be done through numerical control system, which enables the cutter to work normally as before.

Tungsten carbide V-CUT knife is made from tungsten carbide material, that is-tungsten steel, therefore it is also known as solid tungsten steel V-CUT knife. It is commonly used as an electronic cutting tool in the production of circuit boards. The following are some precautions for its use:
1. Tungsten carbide V-CUT knife size shall comply with the requirements.
2. Check the blade first. It should be complete without any cracks, chipping and teeth broken.
3. Collision should be avoided in the handling, installation, commissioning of tungsten carbide V-CUT knife.
4. The blade should be well installed to avoid loosening. And in order to reduce knife vibration and lateral stress, flange plate should not be three times smaller than the knife external diameter. In addition, the radial runout should be ≤0.02mm while axial runout be ≤0.01mm.

Tungsten carbide straight shank reamer is a kind of cutter for pore finish machining and semi-finish machining in reaming process to improve pore machining precision and reduce its surface roughness.It has relatively small machining allowance.
Tungsten carbide straight shank reamer, with one or more hinge cutters,is a kind of rotary cutter used for cutting the thin metal layer in the surface of processed pores. Pores processed by tungsten carbide straight shank reamer can obtain accurate size and shape.
