Mobile phones are now very important communication equipment in our contemporary society. Mobile phones are being updated very quickly. Many young people are also very enthusiastic about mobile phones. But do you know how mobile phone shells are processed on CNC lathes? Let’s take a look at the process of processing mobile phone shells on CNC lathes.
Generally speaking, our mobile phone casings are basically made of metal. The processing flow of metal mobile phone casings:
- Process clamping and positioning:
- X and Y directions are positioned by forging holes, and the cylinder is pressed tightly.
- The bottom 3D surface profile vacuum adsorption processing features: drilling the holes on both sides and the small holes in the middle of the cavity, chamfering to remove the front, milling the blank reference angle, flying knife smooth plane, finishing the positioning holes on both sides.

CNC total time: 55+30+15+5 tool change 10=115S
Two, clamping positioning:
- Positioning by one-clamp machining positioning hole in X, Y direction
- Vacuum suction at the bottom, Z-direction skirt supports the horse to be compressed. Processing features: fine milling cavity features before injection molding (front side)

Three, clamping positioning:
- Positioning by positioning holes in the cavity with two clamps in X and Y directions
- Vacuum suction at the bottom, Z-direction skirt supports the horses and compaction processing features: fine milling cavity features before injection molding (reverse side) CNC machining description: fine milling cavity features before injection molding (reverse side)
Four, clamping positioning:
- Positioning by positioning holes in the two-clamp machining cavity in X and Z directions
- Vacuum suction at the bottom, Y-direction gland pressing tightly Processing feature: precision milling of the headphone hole before injection molding CNC total time: 50S
Five, clamping positioning:
- Positioning by positioning holes in the two-clamp machining cavity in X and Z directions
- Vacuum suction at the bottom, Y-direction gland compression processing features: USB hole CNC total time before precision milling before injection: 90S
Six, clamping positioning:
1, X, Y directions are set by positioning holes machined with 2 clamps
- Vacuum suction at the bottom, Z-direction middle plate support and gland pressing processing characteristics: the characteristics of the front cavity after injection, and the top surface of the two ends are polished to a few. There are three other positioning holes in the fine light cavity.

Seven, clamping positioning:
- Positioning by positioning holes processed by 6 clamps in X, Y directions
- Vacuum suction at the bottom, press tightly on the four sides in the Z direction Processing features: 1. Processing the characteristics of the back cavity after injection molding (select the thicker position to reserve two high-gloss positioning holes);
- Loosen the horses on both sides, rough and finish the appearance of both sides;
- Press the horses on both sides, press the cavity gland, finish the appearance and blanking of the two heads

- Bottom profiling support, gland pressing processing features: processing small holes and grooves on the other side
Eleven, process clamping and positioning:
- Positioning of high-gloss positioning holes for clamp processing
- The bottom profiling support, the gland is pressed tightly. Processing feature: processing the small hole on the side of the USB hole
- Process clamping and positioning:
- Positioning of highlight positioning holes for clamp processing
- Bottom profiling support, gland pressing tightly. Processing feature: high-gloss top
Thirteen, clamping positioning:
- Positioning of high-gloss positioning holes for clamp processing
- Bottom profiling support, gland pressing processing feature: high-gloss bottom
Fourteen, clamping positioning:
- Highlight positioning hole positioning
- The bottom profiling support in the Z direction is vacuum sucked
