Machining a variety of outer surface of the tool, including turning, planing, milling cutter, the outer surface of the broach and file, etc .; hole machining tools, including drill bits, reamer, boring knife, reamer and inner surface broach, etc .; thread processing Tools, including tap, die, automatic opening and closing thread cutting head, thread turning and thread milling cutter, etc .; gear cutting tools, including hob, gear shaper, shaving cutter, bevel gear cutting tools; cutting tools, including inserts Circular saw blades, band saws, bow saws, cut-off tools and saw blades, and so on. In addition there is a combination of tools.

①CDCD hardness up to 8000HV, 8 to 12 times as hard alloy;

②PCD thermal conductivity of 700W / mK, carbide 1.5 to 9 times, or even higher than the PCBN and copper, PCD tool heat transfer quickly;

③PCD friction coefficient is generally only 0.1 ~ 0.3 (carbide coefficient of friction of 0.4 to 1), so PCD tool can significantly reduce the cutting force;

④PCD thermal expansion coefficient of only 0.9 × 10 ^ -6 ~ 1.18 × 10 ^ -6, equivalent to only 1/5 of cemented carbide, PCD tool thermal deformation is small, high precision;

⑤PCD tool and non-ferrous metals and non-metallic materials between the affinity is very small, in the process of chip bonding is not easy to form a chip edge tumor tip.

Tungsten steel cutter

Tungsten steel cutter is a kind of tungsten steel (carbide, also known as tungsten and titanium alloy) production tools. Generally used for CNC machining centers, CNC engraving machine. Can also be installed on the ordinary milling machine to process some of the more hard and uncomplicated heat treatment materials, tungsten steel cutter widely used, the use of high-speed processing. Tungsten steel cutter hardness Vickers 10K, second only to diamonds. Because of this tungsten steel cutter is not easy to be worn characteristics, and brittle hard not afraid of annealing.
