  • Research Status of Metal Coatings

    14 Aug 2017

    Thermal coating of metal coating is the research and application of early wear-resistant coating, commonly used metal (Mo, Ni), carbon steel and low alloy steel, stainless steel and Ni-Cr alloy series coating. In general, flame spraying, arc spraying, plasma spraying, HVOF and explosive spraying pro...

  • The impact of cutting temperature on the workpiece,tool and cutting process

    11 Aug 2017

    High cutting temperature is the main reason for the tool wear, it will limit the productivity; Cutting temperature will reduce the machining precision, make the finished surface residual stress and other defects.

  • The main factors influencing the cutting temperature(三)

    10 Aug 2017

    The strength of the workpiece material (including hardness) and thermal conductivity effect on cutting temperature is great. By theoretical analysis,the unit is an important factor affecting the cutting force of the cutting temperature, and the strength of the workpiece material (including hardness)...

  • Affecting the cutting temperature main factors(二)

    09 Aug 2017

    The influence of the cutting tool geometry parameter Cutting temperature θ decreased by the cutting rake angle γo increases.This is because the former Angle increases, the unit cutting force drops,reduce the heat cutting. However,the former angle is greater than 18 ° ~ 20 °,then reduce the influenc...

  • The main factors affecting the cutting temperature (一)

    08 Aug 2017

    According to theoretical analysis and experimental research knowledge, the cutting temperature is mainly affected by by cutting q‘ty, tool geometry, workpiece material, tool wear and cutting fluid influence, following these few main factors to be analyzed. Analyze the impact of various factors on cu...

  • Cutting heat and cutting temperature introduction(二)

    07 Aug 2017

    Second, the calculation of cutting temperature measurement Despite cutting heat is the source of cutting temperature rise, but the direct impact of the cutting process is cutting temperature, cutting temperature generally refers to the average temperature of the cutting areaθ . The deformation wor...

  • Cutting heat and cutting temperature profile(一)

    04 Aug 2017

    Cutting heat and cutting temperature is another important physical phenomena arising during the cutting process. Cutting the work donecan be converted to an equivalent amount of heat. In addition to a small amount of power cut heat dissipation around the surrounding media, the rest were passed in th...
