First, the turning test was carried out with the cutting amount as the changing condition, and the cutting force and cutting temperature were studied; then the thermodynamic characteristics of the turning insert were studied.
There are many types of drill bits used in metalworking, in twist, diamond and other forms. Choosing the right drill for a given application depends on many factors, such as the type of metal being drilled
The intersection of the major cutting edge and the minor cutting edge creates a nose fillet. The corner radius of the turning tool directly affects the finish of the machined surface. The larger the radius, the smoother the surface. However, if the radius is too large, chatter will occur due to the excessive contact between the tool and the workpiece.
Carbide cutting tools are one of the domestic cutting tools. Under the premise of giving full play to its various advantages, its production cost is relatively low, so in recent years, users who use it to replace high-speed steel milling cutters have grown rapidly. , the following small series will focus on its information.
Because the price of carbide cutting tools is relatively high, it is the responsibility of every machining practitioner to use the tools correctly and make the best use of them. How to use carbide cutting tools correctly mainly includes the following aspects:
