One of the most impressive development in the cutting tool (there is a very clear result: a revolutionary rather than evolutionary), occurred in 1969, chemical vapor deposition (CVD) coating was first used in the alloy tool. Learn from minor adjustments to this widely used in the jewelry industry's technology, tool manufacturers titanium alloy tool coating the introduction of the manufacturing sector. These coating makes the machine operator to doubling their cutting speed (up 500sfpm) five times to extend tool life. The manufacturing sector as a sponge to absorb technology, concentrate on these tool and never look back.cutting wheel

Shortly after the emergence of the titanium alloy coating, the coating of titanium-niobium alloy, it has a the glamorous golden, also has excellent corrosion resistance. Eventually, in 1973, a single layer of aluminum oxide (Al2O3) coating appear in the front, allowing higher cutting speeds (1000sfpm), while improving productivity.

Physical vapor deposition (PVD) coating was accepted in the 1980s. Primarily used for cutting high temperature alloys and titanium alloys, now also used in stainless steel as well as traditional steel. Today, significant coating technology, and over 95% for the processing of iron (iron alloy) the material carbonized tool is coated.flap wheel
