Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a coaxial processing device for deep holes. Background Art

[0002] In the field of precision machining, especially when it comes to high-precision multi-stage deep hole machining, some technical challenges are usually encountered. Deep hole machining itself is a difficult machining process, mainly because the ratio of the depth to the diameter of the deep hole is often large, which makes the tool force complex during the machining process and reduces the machining stability. Especially in the machining of key components such as engine blocks and cylinder head covers, the accuracy and surface quality of the holes are required to be very high, and any slight error will affect the overall performance of the parts. When deep hole machining is performed, long tools are usually required. However, once the length of the tool exceeds a certain value, the insufficient rigidity of the tool may cause vibration during high-speed rotation. Since the tools used for deep hole machining in the related art are prone to vibration, it will not only affect the diameter accuracy of the hole, but also increase the surface roughness of the hole, and may even cause machining errors, resulting in unqualified parts.
