Tungsten Carbide Cutting Tools Liquid Cooling Mechanism

When cemented tungsten carbide cutting tools in addition to frictional heat generated inside the metal molecules within the tool and the shear plane will produce the frictional heat generation, so that cemented tungsten carbide cutting tools the cutting zone temperature can reach 600 ℃ ~ 800 ℃, so require cutting fluid must have good lubrication and cooling performance.

Tungsten carbide cutting tools in the cutting process, the cooling effect of cutting fluid is mainly from the cutting area is quickly taken away by pouring hot coolant to the cutting tool tungsten carbide cutting tools zone generated during cutting, reducing tungsten carbide cutting tools, the temperature of the workpiece, tool life, reduce the thermal deformation of the workpiece, reducing thermal stress and improve the durability of tungsten carbide cutting tools, machining accuracy. Cutting fluid cooling mechanism is: a way to penetrate into the friction area, the deformation zone to play the role of thermal cooling. Cooling of the cutting fluid and the thermal conductivity, specific heat, and the flow rate for the fluid lubrication and related methods, thermal conductivity, specific heat parameters of the better the greater the cooling.
