Boring is the further processing of forging, casting or boring. Boring can enlarge the aperture, improve precision, reduce surface roughness, and can better correct the deviation of the original hole axis. Boring can be divided into rough boring, semi-finishing Boring and fine boring. The dimensional accuracy of precision boring can reach IT8IT7, and the surface roughness Ra value is 1.60.8μm. Boring can be divided into ordinary boring and deep hole boring.


Ordinary boring can be carried out on ordinary lathes, and the boring tool can be fixed on the tailstock or small tool holder of the lathe. Deep hole boring requires a special boring machine.boring machineThe boring handle should be added, and the hydraulic pump station should also use coolant to clean up iron filings. Therefore, in order to meet different needs, attention should be paid to selecting different types of mechanical equipment. Please see the introduction below:
The sum of the pressure used by the boring machine, the resistance loss of the pipeline and the pressure drop of the supporting equipment is set as the lower limit standard for selecting the rated exhaust pressure of the screw boring machine. Under normal conditions and conditions, the gas transmission pipeline with a larger diameter should be selected , in order to reduce resistance loss and achieve the important purpose of reducing long-term energy consumption. The quality of compressed air for boring machines is actually based on the basic requirements of industrial gas equipment for compressed air, so screw boring machines and supporting equipment should be properly selected. Therefore, the following needs to be considered to reduce the actual oil content in the compressed gas.
