Structural characteristics of ceramic indexable blade and precautions for use

due to the unique mechanical characteristics of ceramic blade, the structure of tool and blade has the following characteristics:

1. The strength of blade material (including bending and impact strength) is lower than that of cemented carbide, and the type of non perforated blade is often used

2. The blade edge is mostly chamfered or other enhanced treatment

3. The blade often adopts 0 ° method back angle (special blade sometimes adopts 5 ° and 7 ° method back angle). Also craftsman

4. The non perforated blade is clamped with an up pressing structure, and double clamping is used when necessary

precautions for the use of ceramic indexable blades are:

1. Whether it is turning or milling, dry cutting is often used. If cutting fluid needs to be added, it must be sufficient to prevent blade cracks caused by thermal shock

2. If the blade purchased by the user has not been chamfered, diamond and oilstone strips should be used to chamfer -30 ° ~-20 °, with a width of 0.2~0.4mm

3. Under the same cutting conditions, the arc radius of the tip of the ceramic blade should be larger than that of the cemented carbide blade

4. Pay attention to the fine grinding of the blade. The impact blade should use diamond grivoryht2vs-hh at the center of the support span, and use a stone grinding wheel between 230 ℃ and 250 ℃
