Sheet Metal: Deep Hole Cutting

Sheet metal machining includes traditional cutting and blanking, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, and new stamping technologies. And new processes. Sheet metal machining of parts is called sheet metal machining.

Machining Process

For example, the use of plates to make chimneys, iron drums, fuel tanks, oil tanks, ventilation ducts, elbows, rounded places, funnel shapes, etc. The main processes are shearing, buckling, bending, welding, riveting.

  1. Check if the drawing is complete.
  2. The relationship between drawings and views, whether the labeling is clear and complete, and the dimension unit.
  3. Assembly relationship, assembly requires focus on size.
  4. The difference between the old and new layouts.
  5. Translation of foreign maps.
  6. Surface code conversion.
  7. Drawing problems feedback and burying.
  8. Choose material.
  9. Quality requirements and process requirements.
  10. Official release drawings must be stamped with quality control
