The so-called blisk is actually a relatively important processing element in the entire CNC machine tool processing industry! We all know that blisk processing is just a new type of component designed to meet the needs of high-performance aero engines. It mainly integrates the engine rotor blades and the wheel disc, eliminating the need for tenons, tenon grooves and locking devices in traditional connections. Playing its important role to a certain extent, certain parts can be processed very well. This kind of processing can actually reduce the structural weight and the number of parts. At the same time, it can also avoid the airflow loss of the tenon and improve the aerodynamic efficiency. In the processing technology industry, for rotating surfaces such as outer circles and holes, the machining allowance is considered from the diameter, and generally we call it the allowance. Under normal circumstances, the machining allowance of the plane is the unilateral allowance, which is the actual thickness of the metal layer removed. So why should we leave a machining allowance on the workpiece? Next, let me briefly introduce it to you.

The main purpose of leaving a machining allowance on the workpiece is to remove the machining deviations and external defects left by the previous process. It is no exaggeration to say that the size of the machining allowance has a great impact on the processing quality and production efficiency.

If the machining allowance is too large, it will not only increase the labor volume of mechanical processing, but also reduce productivity. At the same time, it also reduces the consumption of materials, tools and electricity, and CNC processing increases processing costs. If the machining allowance is too small, it will not be able to eliminate various defects and deviations in the previous process, nor can it compensate for the clamping deviation during processing of this process, which will cause waste products to a certain extent.

In summary, the above is the editor’s preliminary understanding of this product. If you want to know more, please call our Xiehe processing manufacturer.
