Rotating knives VS. One-piece
Turning the company for American properties Greenman manager John tool for grinding-cracks of solid carbide cutting tools, the main problem is obvious: "now the price of cemented carbide cutting tools are outrageous, every time I ordered carbide cutting tools of prices higher than last time seem to." This situation has become the main motivation of change. He said, "in the future, we will be preferred by new tools. Now we are still in use, grinding-cracks of solid carbide cutting tools, but the proportion of tools, but only about 35% whenever a new tools can be listed, we will try to use."
Greenman view point. The market Wow Gold Purchase report shows that in the past two years, due to the manufacturing cemented carbide materials para-ammonium tungstate (APT) powder of prices, grinding-cracks of solid carbide cutting tools for the soaring prices 60% ~ 70%. The 13mm diameter for grinding-cracks of solid carbide cutting tools, its price rises exponentially with regularity. On the other hand, the price of which is relatively stable.
Cutting costs and some other factors of cutting tools can be user can change and other blade type impresses tools. Advocates enumerated bits of various advantages, such as cutting machining flexibility, use convenient, productivity high, low, can reduce inventory requirements (or cancelled) change again, knife and adjustment, etc.
Some interviews and machining tool manufacturers, can use workshop tools, this trend is an inevitable trend in the past two years, further accelerate the development. They use "stable" or "slight growth" to describe grinding-cracks of solid carbide cutting tools, and sales of tools can increase in sales, but up to 50% ~ 200%.
However, this does not mean the end of grinding-cracks of solid carbide cutting tools. In many areas, including processing mould processing, still need to use solid carbide cutting tools. Make solid carbide tools become preferred standard many advantages, such as high rigidity, low vibration, now still exist.
Kennametal global milling product manager Tim Marshall did not think of rising prices of raw materials is solid carbide tools were snubbed the only reason. He said: "I think the user selects small diameter can be tools of reason is in size can have more choices.
