The new concept of cutting processing
The nowadays cutting tool company cannot only be again the
manufacture and the sales cutting tool, in order to succeed, Precision CNC machining parts they must be consistent with
the globalization manufacture tendency maintenance, through enhances the
efficiency, cooperates with the customer reduces the cost. Approaches the
instantaneous global competition after this after NAFTA, the WTO time, the
world company is making quickly to the same feeling, is lighter, a cheaper
response. In other words, they make the product and the components contain can
in high speed under revolve, as a result of the cost pressure, best, is lighter
moreover must make cheaply. Obtains these goals a best way is through develops
and applies the new material, but these is new and the improvement material
usually all with difficulty processes. In in this kind of commercial power and
the technical difficulty combination is especially prominent in the automobile
and the aviation industry, and has become has the experience the cutting tool
company to research and develop the department the most important driving
influence.
For example, takes the modular cast iron to say that, it has become
the engine part and other automobiles, the agriculture the material which see
day by day with the equipment and in the machine tool industry components. Precision CNC machining parts This kind of alloy provides the low production cost and the good
machine capability combination. They are cheaper than the steel products, but
has a higher intensity and toughness compared to the cast iron. But at the same
time the modular cast iron is extremely wear-resisting, has fast breaks by
rubbing the cutting tool material the tendency. In this wear resistant very
great degree bead luminous body content influence. Some known modular cast iron
bead luminous body content higher, its resistance to wear better, moreover its
machinability is worse. Moreover, the modular cast iron porosity causes off and
on to cut, this even more reduces the life.
May estimate that, PrecisionCNC machining parts the high degree of hardness and the
high wear-resisting cutting material quality must consider the modular cast
iron the high resistance to wear. And the material quality contains extremely
hard TiC in fact (carbonized titanium) or TiCN (carbon titanium nitrides) thick
coating when cutting speed each minute 300 meters processes the modular cast
iron to prove usually is effective. But along with cutting speed increase,
scrap/The cutting tool junction
plane temperature also is increasing. When has
such situation, the TiC coating favors in has the chemical reaction with the
iron and softens, more pressures function in anti- crescent moon hollow
attrition coating. Under these conditions, hoped has one chemical stability
better coating, like Al2O3 (although under low speed was inferior to TiC hard
or is wear-resisting).
