CNC carving hand processing of ten questions and answers

CNC carving hand processing of ten questions and answers

1. What are the main differences between CNC engraving and CNC milling?

CNC engraving hand processing and CNC milling hand processing have adopted the milling hand processing principle.The main difference is in the diameter of the tool used, which CNC milling hand processing commonly used tool diameter range is 6-40 mm, while CNC engraving hand processing tool diameter is 0.2-3 mm.

2 CNC milling hand processing can only do rough hand processing, CNC carving hand processing can only do fine hand processing?

To answer this question, let's first take a look at the concept of process.Rough hand processing process of hand processing, fine hand processing of hand processing quantity is small, so some people habitually will be rough hand processing is considered to be "heavy cutting", the fine hand processing is considered to be "light cutting".In fact, rough hand processing, half fine hand processing, fine hand processing is the concept of the process, it represents different stages of hand processing.So, the accurate answer to this question is that CNC milling can do heavy cutting, can also do light cutting, and CNC engraving processing can only do light cutting hand processing.

3. CNC engraving prototype processing can do steel material rough prototype processing?

To judge whether CNC engraving processing can process a material by hand, mainly depends on how big the cutting tool can be used.The cutting tool used for CNC engraving determines its maximum cutting capacity.If the die shape allows the use of tools larger than 6 mm in diameter, it is strongly recommended that the remaining material be removed with a CNC milling hand, followed by an engraving hand.

4. Is it possible to add a growth head to the spindle of CNC hand plate processing center to complete the processing of engraving hand plate?

Can't finish.This product has appeared in the exhibition 2 years ago, but can not complete the processing of carving hand board.The main reason is that the design of CNC hand processing center considers its own tool range, the overall structure is not suitable for carving hand processing.The main reason for this misconception is that they mistook the high speed motorized spindle as the only feature of the engraving machine.

5. CNC engraving hand processing can use a very small diameter tool, it can replace the EDM hand processing?

There is no substitute.Although engraving hand machining reduces the tool diameter range for milling hand machining, small molds that previously could only be processed by electric spark hand machining can now be achieved by engraving hand machining.However, the length/diameter ratio of the carving hand processing tool is generally about 5:1.When the use of small diameter tools, can only hand processing is very shallow cavity, and the EDM hand processing process almost no cutting force, as long as the electrode can be made, you can hand processing cavity.

6. What are the main factors affecting the processing of engraving hand board?

Mechanical prototype processing is a more complex process, the influence of its factors are more, mainly there are the following points: machine characteristics, cutting tools, control system, material characteristics, prototype processing technology, auxiliary fixture and surrounding environment.

7. What are the requirements of CNC engraving hand processing on the control system?

CNC carving hand processing is the first milling hand processing, so the control system must have the control ability of milling hand processing.For small tool hand processing, at the same time must provide the feed forward function, the path in advance to reduce the speed, reduce the frequency of small tool break.At the same time, the cutting speed should be improved in the relatively smooth path section, so as to improve the processing efficiency of engraving hand board.

8. What characteristics of the material will affect the processing of the prototype?

The main factors affecting the engraving performance of materials are material type, hardness and toughness.Material categories include metallic materials and nonmetallic materials.In general, the greater the hardness, the worse the workability, the greater the viscosity, the worse the workability.The more the impurities, the worse the processing, the greater the hardness of the particles inside the material, the worse the processing.A general standard is: the higher the carbon content, the worse the processing, the higher the alloy content, the worse the processing, the higher the content of non-metallic elements, the better the processing (but the general material of the non-metallic content is strictly controlled).

9. Which materials are suitable for carving hand plate processing?

Non-metallic materials suitable for carving include plexiglass, resin, wood, etc., and non-metallic materials not suitable for carving include natural marble, glass, etc.Metal materials suitable for engraving include copper, aluminum, soft steel with hardness less than HRC40, and metal materials not suitable for engraving include hardened steel, etc.

10. What is the impact of the tool itself on the processing of the hand plate, how to affect?

The cutting tool factors affecting the processing of engraving hand plate include cutting tool material, geometric parameters and grinding technology.Carving hand processing used cutting tool material is cemented carbide material, it is a powder alloy, the main performance index to determine the material performance is the average diameter of powder.The smaller the diameter, the more wear-resistant tool, the higher the durability of the tool, the more CNC programming knowledge concerned about WeChat public number (CNC programming teaching) to receive the course, the sharpness of the tool mainly affects the cutting force.The sharper the tool, the smaller the cutting force, the smoother the processing of the hand plate, the higher the surface quality, but the lower the tool durability.Therefore, in the hand processing of different materials should choose different sharpness.prototype processing is soft and sticky material, the need for a sharp tool, when the hardness of prototype processing material is large, to reduce sharpness, improve the durability of the tool.But can not be too blunt, otherwise the cutting force is too large, affecting the processing of the hand plate.The key factor of tool grinding is the number of mesh of finishing grinding wheel.Grinding wheels with higher mesh can produce finer cutting edges, which can effectively improve the tool's durability.Higher mesh grinding wheel can produce a smoother back surface and improve the quality of cutting surface.
