According to the tungsten carbide cutting tools market forecast made by China's machine tool industry association tools branch,in the next five years, China's market of tungsten carbide cutting tools will remain higher than the overall GDP growth rate, a conservative forecast of 10% -15%; high-end carbide With the industrial upgrading of the tool and to further improve the level of equipment, will continue to maintain high growth, it is expected to grow more than 15%.

In addition, according to China's "tool industry," second Five Year Plan "(draft recommendation)," an explicit proposal to significantly improve efficiency of domestic tungsten carbide cutting tools in manufacturing high-end market share, targets the high-end market share to From around the current 15% to 30% -40%; and conceive again 2-3 five-year plan period, so that the localization rate gradually increased to the average level of developed countries, 60% -70%. To accomplish this goal, the localization rate of average annual growth rate will reach 20%. It can make another tungsten carbide cutting tools market forecast: production of tungsten carbide cutting tools will also reach a new historical level during"Twelve Five" period.

Since carbide saw blades are circular, they are radially the stiffest elements of the power train in the direction of the feed, but very unstable perpendicular to the feed direction. Due to the thin blade body the blades must be stabilized to minimize the side vibration amplitudes. When the first experiments with carbide saws were made, the blade stabilizer was developed using two plastic coated ball bearings mounted on eccentric shafts and supported by a welded bracket to the gearbox.  Recently the new patten has been developed, a pair of front stabilizers for machines arranged close to the point at which the blade enters the material. These stabilizers hydraulically extend, when the carbide teeth have moved past the stabilizer tips before cutting and stabilize the blade which also help to guide the blade into the cut to improve the accuracy.

Generally the selection of the insert shape of a tungsten carbide cutting tool is depends on the work material, the required production rate and the condition of the machine tool. And the shape of a tungsten carbide insert is specified by the first letter of the insert designation, which include diamond, triangle ,square,octagon, round and trigon.



Furthermore, the shape of an insert largely determines the carbide tool ‘s strength, quantity of cutting edges and the total cost. It is claimed that when the insert becomes stronger and dissipates heat more rapidly as its included angle is increased, so there’s a trade-off between strength and versatility during the insert shape selection. For instance, round inserts is an ideal option for roughing operation considering it could offer maximum edge strength, while the square inserts are popular in general purpose due to its good edge strength and bunch of cutting edges.

For a tungsten carbide hand cutting tool involved in axial milling, there are several rake angles to be addressed, all addressing cutting forces for a given material. Side rake is relative to cutting edge. With positive tungsten carbide hand cutting tools the rake is in the tool, for negative tools, the rake is relative to the position of the tool to the center line. Since there’s no clearance in negative inserts, clearance is provided by normally having a 5 to 7 deg negative rake and side rake for clearance to avoid rubbing.  Shear plane is recognizing as the shearing of metal at a given plane, that is relative to the cutting edge.  A negative plane offers less shear, more pushing of the material, more horsepower and a stronger edge engaged in the cut zone. A positive plane reduces cutting forces offers freer cutting, less horsepower and a weaker cutting edge. Clearance is the angle below or behind the cutting edge.
