Technology

 CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.

The advantages of CNC machining which compare with SLA and SLS processing:

◆ The material is very close to the engineering material designed. But the material of SLA is photosensitive resin ,the performance only can close to ABS; and the material of SLS is a powder, Nylon is commonly used;

◆There are no limited size for CNC prototype processing method, for the big size prototype , we can split the parts need to process to several small pieces, and the bonding the small pieces after processing ,the effect is close to the overall processing.

Pay attention: the split parts only limited ABS,PC,PMMA three kinds material.

The commonly used material list of CNC prototype production:

       Plastic material:

◆ABS                          ◆PP                          ◆PC

◆PA                            ◆PMMA                     ◆POM

◆PP                            ◆PEEK                       ◆PVC

  Metals material:
          

   ◆6061 Aluminum              ◆6063 Aluminum

   ◆ss302、ss303、ss304、ss316 stainless steel

What kind of prototype are suitable for CNC processing method to make?

◆Exterior prototypes;

◆The material capability are required (such as pp material cannot fracture for when bending)

◆prototype with metallic material

◆prototype with big size ;

         

The data you need to provide to us if you adopt CNC machining:

◆Please send us 3D drawing which the suffix is prt、step、iges、x_t、sldprt.

◆Explain theprototype’s quantity、material、color and surface effect of every 3D picture; you had better make a list ,As show blew:

◆ provide the internationally accepted color, such as pantone: cool grey 3c,but not only cold grey;

◆There are three kinds of surface paint effects: glossy surface, matt surface, sand surface, every prototype need spray should explain the surface effect;

◆The prototype which the surface require screen printing and laser carving, need to provide the proportion 1:1 adobe illustrator(AI) or Coreldraw file, and explain screen printing font pantone color.

The prototype which need to control the size tolerance and assemble requirement, should indicate clearly by PDF or JPEG requirements during prodcing;
