Cemented Carbide Tool Wear Characteristics and Composition

Cemented carbide tool wear includes abrasion wear, crater, chipping,  thermal cracking, gap, abnormal debris, etc.

The mechanism of various cemented carbide tool wear occurred associated with the characteristics of the cemented carbide tool wear as shown in  the table below.

Cemented Carbide Tool Wear Relationship

Cemented carbide tool wear includes abrasions wear, crater, chipping, thermal cracking, gap, abnormal debris, etc. Various cutting edge wear occurs only one time is considerably less, and almost always is interrelated and occur simultaneously,the tool wear relationships together, as shown below.

Cemented Carbide Tool Wear - Peeled Into Pieces

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

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.

Cemented Carbide Tool Wear - BUE Peel

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

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.

Cemented Carbide Tool Wear - Exception Debris

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

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.

Cemented Carbide Tool Wear - Notch

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

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.

Cemented Carbide Tool Wear - Crater

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

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.

Cemented Carbide Tool Wear Introduction - Part1

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

(一) 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.

Cemented Carbide Tool Wear

Cemented carbide tool wear is the phenomena, in high temperature conditions the tool material is gradually wear or breakage by the workpiece, the friction of the chips. Research tool wear causes prevent premature excessive tool wear and how to extend tool life, which is affecting the efficiency of production, processing costs and processing quality is an important topic.

Cemented carbide tool wear in the form of: Cemented carbide tool wear normal and abnormal tool wear can be divided into two categories. Normal tool wear the continuous gradual wear and tear, abnormal tool wear, including brittle breakage and plastic damaged two.
1. Normal cemented carbide tool wear: increase wear gradually expanded form, including wear in front of the main flank wear, vice flank wear with cutting time.

2. Abnormal cemented carbide tool wear, also known as broken
