机夹可换多面刀片的刀具的应用,是减少硬质合金及其他刀具材料耗量、增加设备功率与时间的利用系数和提高劳动生产率的途径之一。这种刀具与焊接的刀具相比,有下列许多优点:不会受热,实际上能避免在硬质合金上形成有害的拉伸应力和裂纹,因此能使刀具寿命和劳动生产率提高30%,可利用更耐磨牌号的硬质合金;能迅速更换刀片(大多数情况下无需从机床上取下刀具);刀具几何参数恒定不变;可减少刀具的品种和刀杆钢材耗量;可在这种刀片上涂覆耐磨涂层,因而能使刀片寿命提高2～3倍并能扩大其应用范围。对刀片的
The utility model can be used to replace the cutter with the multi-faceted blade, which is one of the ways to reduce the consumption of the cemented carbide and other cutter materials, increase the utilization factor of the power and the time of the equipment, and improve the labor productivity. This type of tool offers the following advantages over welded tools in that it does not get heated and virtually avoids the formation of unwanted tensile stresses and cracks in the cemented carbide and therefore increases tool life and labor productivity by up to 30% The use of more wear-resistant grade carbide; can quickly replace the blade (in most cases without the need to remove the tool from the machine); tool geometry constant; can reduce the variety of tools and knife bar steel consumption; The blades are coated with a wear-resistant coating that increases blade life by 2 to 3 times and expands the range of applications.
