Fixture has been widely used in many fields,from welding,assembly,to the various clamping tools used in machining,they can be called fixtures.Among them,the machine tool fixture can help people accu-rately install the object to the specified position,so as to ensure the accuracy and safety and reliability of the clamping,so as to adapt to different work requirements.For the processing of thin-wall bushing parts,the ma-chine tool fixture is undoubtedly a crucial equipment,and its quality,performance,service life and price will have a significant impact on the quality of the final part product.The problem of easy deformation is common in the processing of thin-wall bushing parts.For the challenges existing in this field,we should take effective meas-ures to improve the processing rigidity,reduce the deformation of the workpiece,and ensure the processing accu-racy to achieve the best processing effect.
