Chemical Resistance CNC Resin Composite Tooling Board

Processing steps of resin composite tooling board for CNC

What are the advantages and disadvantages of substitute tooling board?

1)Advantages: strong stability, not easy to deformation; Disadvantages: brittle toughness, easy to knock and fracture. There are different types of wood substrates on the market, both polyurethane and epoxy. The substitute wood material that produces with different base material resin also can have a variety of difference in performance respect.

What is the use of tooling board substitutes?

Then as a kind of rapid prototyping materials in today's society has been applied to all walks of life, such as aviation, inspection tools, non-metal mold and so on.

How to process wood?

1. Ordinary substitute wood materials can be processed with traditional belt tools.

2. For the complicated substitute wood surface, it is generally divided into three axis and five axis machine tools to complete the processing. Three axis machine tool we are not here to do an overview, I believe you can understand.

How to achieve high efficiency, high speed and high precision in the processing of wood for five-axis machine tool?

We now take a workpiece as an example to see the whole process of wood generation.

The first step, will replace the wood fixed on the work table, with pressing plate and other tools, do not need to use adsorption, because the plane of the wood may not be good with adsorption effect.

The second step, prepare the tool, the processing of wood often used tool material for carbide. Carbide tools are also divided into the overall carbide tool and blade coating carbide. The former is more expensive, the latter is more cost-effective, the current enterprise applications are different.

The third step is to set machining parameters in the programming software. In general, the spindle speed of the processing of wood substitutes is between 10000-20000, the feed is between 8000-10000mm/min, and the draft is between 0-15mm.

Step 4: set the origin of coordinates, set the knife, and start the execution program button.

The fifth step, as the wood is brittle, try to use an arc feed knife, if the use of straight line, the wood is easy to crack.

Step 6: dust treatment during processing. The generation of wood in the processing of extremely small dust will have an impact on the surrounding environment, this time is about to start the vacuum device. Xinghui generation wood five axis processing center successfully solved this problem. Add a telescopic vacuuming device on the main shaft, which can effectively suction dust and avoid the interference between the vacuuming hood and the workpiece.

Step 7, the overall environmental protection of the machine closed. The wood generation five-axis machine adopts a fully enclosed structure, including the top, which forms a separate closed operation bin during processing.

Step 8: the follow-up treatment after processing. Due to the high speed of machining and other good cutting parameters, reasonable tool, the high precision of the five-axis machining center itself, decided the surface quality of the wood must be smooth and stable. The machined substitute wood surface quality does not need to be polished and other post-processing.

Step 9: product inspection. For the workpiece after processing, each unit according to the different needs of the product three coordinates or photographic measurement. For the workpiece after the measurement is correct to turn down the work, the five axis processing to complete here.

Key Properties
