CNC blade is a kind of tool made of tungsten steel (cemented carbide, also known as tungsten titanium alloy). Tels NC blade recycling is mainly used in CNC machining center and CNC engraving machine. It can also be installed on the ordinary milling machine to process some relatively hard and uncomplicated heat treatment materials. Numerical control blade is widely used and high-speed machining is used. The hardness of NC blade is Vickers 10K, second only to diamond. Because of this, NC blade is not easy to be worn, and it is brittle and hard, not afraid of annealing.
There are many kinds of numerical control blades. For milling cutters with the same shape, the price difference is very large. It is difficult for ordinary consumers to judge their advantages and disadvantages, but it is easy to judge their advantages and disadvantages as follows:
See the origin of cemented carbide used for NC blade. Brand. Generally, the price of imported cemented carbide materials is 2-3 times that of domestic materials. The prices of different brands also vary greatly.
2. Look at the appearance, angle, bright surface, laser printing, front end of milling cutter, flat teeth, uniform back angle, any chipping, burr, crack, etc. of NC blade, so as to determine the manufacturing process of NC blade; machining center production or ordinary machine production. The accuracy of cutting tool produced by machining center is several times of that of ordinary machine.
3. The tail shank of the drill bit shall be flat and the chamfering shall be consistent, the inner and outer packing shall be provided, the report shall be made on the label, and the name of the manufacturer shall be complete.
Cemented carbide tools (especially indexable cemented carbide tools) are the leading products of CNC machining tools. In some countries, more than 90% of turning tools and 55% of milling tools are made of cemented carbide, and this trend is increasing.
Since the 1980s, the tool industry has been expanding the production of all kinds of integral and indexable cemented carbide tools or inserts, and their varieties have been extended to all kinds of cutting tools. The indexable cemented carbide tools are expanded from simple turning tools and face milling tools to various precision, complex and forming tools.
Cemented carbide is also a common material for making drill, face milling cutter and other general cutting tools. At the same time, the use of cemented carbide in reamer, end mill, medium and large modulus gear cutter and broach is increasing. The annual output value of cemented carbide tools and inserts has accounted for more than 30% of the total output value of cutting tools.
