Processing steps of resin composite tooling board for CNC
What are the advantages and disadvantages of substitute tooling
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
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
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.
1. Easy workability • High dimensional stability
2. Cost effective • Good compressive strength
3. High Temperature and chemical resistance • Large sheet sizes
4. Smooth, non-porous surface finish • Low coefficient of thermal
