    Chamfering grain problem from high-ray CNC machine

    Date:2018-08-15 Click:3391 次

    Chamfering grain problem from high-ray CNC machine
    The knife grain on the chamfer made by the high-ray CNC machine is mainly caused by:
    I. High precession requirements of the high-ray CNC machine;
    II. Good rigidity of the high-ray CNC machine;
    III. Engagement of the cutting edge and feed speed;
    IV. Part structure and fixture;
    V. The cutting heat is too high and the cutting speed is too low;
    VI. Tool and cooling
    Tool factors: tool material (the diamond tool is commonly used), tool angle design and knife handle dynamic balance.
    Cooling factors: coolant and the existence of high-pressure cooling.
