The CNC machining contains vertical machining centers (CNC centers), large-sized milling machines, CNC lathes, precision jig boring machines, conventional milling machines, lathes and grinding machines and so on.

The CNC Machining working process
 
1. drawing making
    no matter whether you provide us drawings including PDF, CAD or 3D in different format, we must convert them to our version.
 
2. machining way
   engineering dep. and produce dep. will have a meeting to discuss the best and competitive machining way.
 
3. material preparation
   a. buy stock material plate, bar or pipes;
   b. forged material;
   c. casting mterial;
   d. extrusion (aluminum);
   e. injection (plastic)
 
4. CNC machining
   the whole process may covers the following,
  a. CNC milling
  b. CNC drilling
  c. CNC boring
  d. CNC turning
  e. bending
  f. punching
  g. EDM
  h. flame cutting
  i. welding
  j. electric spark
 k. CNC grinding
the above process has no strict sequence, and should be different with different parts.
 
5. QC check
  every step of point 4 should be check by QC , then can start next process
 
6. finishing
  according to customer"s requirement and different material the finishing requirement has,
  a. nickel plated
  b. blacken
  c. chrome plated
  d. zinc plated
  e. color anodized
   f. polishing
  g. phosphorization
  h. acid pickling
  i. paint
  j. powder coated
 
7. QC check
  after finishing, QC should check the surface of all parts.
 
8. Take pictures
  take pictures and send to customer
 
9. Pack
  pack all parts with customer's requirement, eg. film+bubble+carton+wooden case/pallet.
 
10. Take pictures
  take pictures of the packing pictures.
