Process: sand casting process, shot blasting, spray painting, precision CNC machining, tempering treatment, non-destructive testing.
Process analysis: The product is the crusher shell, the wear-resistant steel is used for shell production, and the resin sand process is used for shell production. After the casting production is completed, the polished blank will be tempered to achieve a processable state. After the tempering treatment, non-destructive testing should be carried out on the whole shell, UT,MT testing should be done to confirm that there is no defect, shot blasting and sandblasting should be carried out to remove the surface oxide. And then do the anti-rust paint spray. After the completion of the above projects, the blank production is completed, transferred to the processing process, after vertical lathe processing, gantry machining center processing to reach the drawing accuracy and size, after professional quality inspection personnel inspection, issue a test report, including material report, size testing report, non-destructive testing report. One package per piece, shipped.
