CNC machining and hand polishing of plastic prototypes

compared with hardware materials, plastic materials have the advantages of easy processing and low cost, so they are widely used in the prototype industry. If you make a plastic prototype, most of them are CNC machining. This is not only a high precision, but also a good performance. It is a very popular processing method. Here is a detailed introduction to the CNC machining and manual polishing of the plastic prototype.

CNC machining

, first, the solid raw materials are fixed on the CNC machine. There are many kinds of fixing methods. Double-sided tape, glue, and atomic ash can be used. However, it is necessary to ensure that the raw materials are not loose within the processing range.

B, and then start the machine to fully automatic CNC washing and cutting the programmed 3D file data.

manual polishing

, first clean up the parts processed by CNC, and clean up the unwanted edges and residues.

B, and then check the physical objects of the accessories with the 3D files, whether the processing is in place, if there are any omissions, secondary processing will be carried out.

C, manual repair, processing difficulties on accessories, if the processing is not in place, manual repair will be carried out. For example, if the small hole is too deep and is not fully opened during the processing, it needs to be repaired by hand with tools. For example, if the tool cannot wash the right angle of the cut, the tool needs to be repaired.

D, the appearance surface is polished with the special mating surface, since it is impossible to achieve a completely smooth and smooth surface after CNC machining, the knife will be left, then it needs to be polished with sandpaper and No. 240- The sand number of No. 1200 ranges from coarse to fine, so as to achieve the desired appearance effect.

above is the prototype of plastic detailed explanation of CNC machining and manual polishing of the model, hope to help you.

Anyone who has seen the latest rapid prototyping manufacturers china cnc gantry in operation cannot help but be impressed with how far the technology has progressed over the past few years.
