Precision Solutions For Machining Slender Shaft

1.What is a slender shaft?

An axis with a ratio of length to diameter greater than 25 (ie L/D > 25) is called an elongated shaft. Such as the screw on the lathe, light bar and so on.

2.The machining difficulty of the slender shaft:

Due to the poor rigidity of the slender shaft, the cutting force, the cutting heat and the vibration, etc. during the turning process, it is easy to produce deformation, and there are machining errors such as straightness and cylindricity, and it is difficult to achieve the shape accuracy and surface on the pattern. Technical requirements such as quality make machining difficult. The larger the L/d value, the more difficult the turning process.

3. Key issues in machining slender shafts:

The slender shaft has poor rigidity. Due to the influence of various factors such as the machine tool and the tool during the machining process, the workpiece is prone to defects such as curved waist drum shape, polygonal shape, bamboo shape, etc., especially in the grinding process, the general size is poor and the surface is rough. The degree is required to be higher, and the workpiece is generally required to be quenched and quenched and tempered by heat treatment during grinding. The cutting heat during grinding is more likely to cause deformation of the workpiece, etc. Therefore, how to solve the above problem becomes a superfine processing Long axis key issues.

4.PTJ Shop solution:

The key technology for turning slender shafts is to prevent bending deformation during machining. To this end, measures must be taken from fixtures, machine tools, process methods, operating techniques, tools and cutting volumes. In the face of the processing of the slender shaft, the quick-adding net has a unique solution to the formulation of the process plan, the selection of equipment, and the design of the fixture. Usually the processing of the slender shaft is done by the CNC. For the slender shaft with high concentricity, especially when the design of the part does not allow the U-turn machining, the PTJ Shop will select the multi-axis machining equipment to quickly process the parts in place (such as four). Axis CNC or five-axis travel machine).
