There are many problems in the design and processing of non-standard cutting tools
The geometric shape of the tool is relatively complex. During heat treatment, the tool is prone to bending, deformation or local stress concentration. Therefore, attention should be paid to avoid the parts prone to stress concentration in the design. For parts with large diameter change, bevel transition or bench design should be added. If it is a slender piece with large length diameter ratio, it is necessary to check and straighten every time it is quenched and tempered to control its deformation and runout.
The material of the tool is relatively brittle, which is cemented carbide. This makes the tool break when the vibration is large or the processing torque is large. This will not cause great damage in the process of using conventional tools, because the tool can be replaced, but in the process of using non-standard tools, because the possibility of replacement is not great, once it occurs A series of problems, such as delivery delay and so on, will cause users great losses.
All of the above are aimed at the tool itself. In fact, the manufacturing of non-standard cutting tools is not so simple. This is a systematic project. The experience of the manufacturer's design department and the understanding of the user's processing conditions will affect the design and production of non-standard cutting tools. The processing and testing means of the production department of the tool manufacturer will affect the precision and geometric angle of the non-standard tools. The repeated return visit and collection of data and information by the Sales Department of the tool manufacturer will also affect the improvement of the non-standard tools, which will help users to use non-standard tools Success plays a decisive role.
In a word, nonstandard cutter is a kind of special tool which is produced according to some requirements. Choosing an experienced manufacturer will save a lot of time and energy for users
