Cemented Carbide Tool Wear

Cemented carbide tool wear includes abrasions wear, crater, chipping, thermal cracking, notch, abnormal debris, etc.

(1) Cemented carbide tool wear - abrasions wear: As shown, when behind quite severe wear occurs strip cutter, fine particle materials, and to enhance its hardness and strength after high temperature quenching. Recommended material contains a trace of tantalum carbide. Specific, such as the following example shows, the direction of the arrow to the selected material.

K10 Material→K05 Material

(2)(B) Cemented carbide tool wear - crater: face quite powerful concave wear occurs, consideration should be given high temperature diffusion and intensity, recommend the use of titanium carbide, tantalum carbide content material. Specific, such as the following example shows, the direction of the arrow to the selected material.

P20 Material→P10 Material

(3)Cemented carbide tool wear - chipping: When the tiny nibs after falling, and then carefully grinding tool tip should be honed cutting edge, can significantly reduce the debris. For those who need to use a large rake angle during processing of the material (for example, soft steel), refer to the following example to select the tool material.

K10 Material→K20 Material

(4)Cemented carbide tool wear - Thermal cracking: current face or the back of serious cracks, it is recommended to use M Series material that thermal conduction properties, not easy to produce thermal fatigue.

P20 Material→M20 Material

(5)Cemented carbide tool wear - notch: a relatively large gap along the blade, impact resistance, in order to strengthen the cutting edge of the anterior horn corrected to the negative direction. If it is useless to change the blade shape, it is better to choose high toughness materials.

P20 Material→P30 Material

(6)Cemented carbide tool wear - exception debris: a serious gap in the cutting edge due to heat, reduce the cutting speed, or the use of high-temperature materials.

P10 Material→M10 Material

(7)Cemented carbide tool wear - BUE peel: In many occasions, in the front (or back) to remove the BUE, phenomenon occurs when the cutting edge is peeled. In this case you want to select a large rake angle, or increase the cutting speed.

P20 Material→M30 Material

(8)Cemented carbide tool damage - plastic deformation:
Can be selected for plastic deformation due to the intense heat generated in the cutting blade, a low cobalt content, high temperature, high strength materials.

P30 Material→P20 Material

(9)Cemented carbide tool wear - peeled into pieces: the elastic deformation due to the vibration of the workpiece material in the cutting generates, in front peeling, then choose a high cobalt content, good toughness material.
