Tungsten Carbide Cutting Tool Drilling Parameters In

Tungsten carbide cutting tools and drilling is based on carbide drill or reamer hole machining mold parts on drilling methods, drilling tool and the workpiece relative motion and axial feed movement. Carbide cutting tool drilling parameter refers to the cutting speed, feed per revolution, penetration or feed rate and depth of the hole four parameters. The cutting speed is at a point on the cutting edge with respect to the surface to be machined in the direction of the main movement of the instantaneous speed. From the standpoint of hole machining, the bore may represent a major factor characteristic comprises: the diameter, depth and quality of materials, processing conditions, or conditions, reliability, productivity.

Carbide cutting tool drilling parameters of cutting speed, usually with the letters VC expressed in units of m / min, is determined by the circumferential speed, the cutting speed can be calculated using the spindle speed (n) to get. Spindle speed is expressed in revolutions per minute. In a turn, the drill perimeter of π × Dc, Dc for drill diameter. Drilling cutting cutting parameters will change, depending on the cross section of drill cutting edge. From the center to the circumference of the drill, its speed from zero to the maximum. The recommended maximum speed of the peripheral cutting speed.
