Hello. At this time, I offer to find out in the framework of the repair of the course on how to frame facades are made of MDF profile with their hands and how to do it at the specialized enterprises. Subject of the article will be of interest to owners of gold hands and a home workshop, where there is a miter saw and other carpentry tools.
The ideal solution for the assembly of classic furniture
A few words about what we do
Frame fronts MDF Profile - a team structure, consisting of a frame, and a shield that is inserted into the frame. Frame design can be made taking into account the different sizes and of different configurations, which is very important in the manufacture of furniture components to order.
Appearance cuisine of MDF frame
This advantage is not different facades, covered with foil or plastic. Due to the presence of different cross-section profiles can be made on the facades of various configurations, color performance and appearance in general.
The design of the frame of the facade
Facade frame type includes board - and the applicator obklada panels made of profile. The appearance of the finished product largely depends on the shape of the cross-sectional surface-girth.
Assembling furniture frame fronts
So going to the kitchen framework of MDF with corner joints direct spike
Manual assembly process is shown in the following diagram.
Consider the points listed in detail.
Methods of cutting "on the condition" popular compound
It would look like the cross section of the frame with the filling
In order to connect the profile for the frame fronts MDF compound used in the corners "on the condition" - in this case 45-degree angle to the rectangular facades. Consider how the profile cut at an angle of 45 degrees and provide proper docking profiles without visible gaps.
Among the most popular ways marked by three:
- Cutting manually using the miter box - the optimal solution for working at home;
- Cutting with an electric miter saws;
- Cutting on the sawmill.
Each of these methods provides a high precision of the connection when done correctly with their hands. Select one of the following methods performed in accordance with the degree of equipping your workshop.
Metal miter box for professional cutting
Cutting on the miter box as follows:
- Profile is placed in the right side of the miter box and pressed to the side;
- Special hacksaw is cut;
- Cropped face treated with sandpaper for better contiguity to other parts of the frame.
Cutting profile, use only metal miter box as wood, plastic and even more tools from long application developed and provide accurate positioning handsaw and, consequently, do not guarantee the accuracy of the cut.
The easiest way to cut the profile involves the use of the miter saw.
Splitting the bar on the miter saw
cutting procedure is as follows:
- Profile applied closely to the stopper guide;
- The cutting blade is lowered to the profile and can determine how the workpiece is properly inserted and selected size;
- Turn on the saw and the cutting blade is lowered for cutting.
The quality of the cut in the combined bars perfect
The advantage of this method is that the disk is lowered by an angle strictly verified without vibrations and without backlash from side to side. Therefore, the most accurate cut and the compound in a frame will be formed without gaps.
Cutting bar at sawmill
The third method is recommended if there is a quality sawmill, as in the photo, but there is no cross-cut saw. In this case the profile is fixed at an angle of 45 degrees with respect to the disc saws and cut is performed.
joint checking on a square
At the end of slicing put on a square table and the workpiece thereon butted to determine the accuracy of the compounds and the presence of gaps.
If the gap is not, you can start gluing.
Assembling the blanks in the finished product
Now you know how to cut the profile to the desired angle. It remains to learn how to assemble the workpiece in a single facade.
assembly instructions, as follows:
Equipment for milling gaps under the dowel
- The blanks are installed in a special milling machine;
Milling combined items
- Using shaped grooves are cut by milling dovetail;
- The ends of the blanks are coated joiner's glue Fast and connected;
Alignment dowels details
- The milled grooves dowels are inserted and driven in with a hammer;
Cleaning the surface of the adhesive
- With the connection terminals removed excess adhesive;
- On the inner side of the frame around the perimeter of a layer of wood glue fast, which keeps the insert;
- After complete drying of the glue product is ready for subsequent operation.
In some cases, the filling of the facade, or as it is called infill, is not inserted during assembly in specially sliced in the manufacture of the groove, and is pasted on the back side.
This method allows to use as filling-piece, and a dial panels are composed, for example, lining or wall panels. Installation of panels in the groove is not performed in the process, and at the end of the frame assembly that simplifies the technology.
The following table lists the tested adhesive species that can be used to build facades MDF.
|Name||Packaging||drying time||Extras. Intelligence.||Price|
|Moment-installation Henkel (Russia)||a gun tube assembly 280 g||15 minutes before curing||Colorless, odorless, without express||from 260 rubles.|
|Titebond Heavy Duty||a gun tube assembly 280 g||15 minutes before curing||light brown, waterproof||from 250 rubles.|
|Makroflex MF220||tuba for mounting the gun 460g||10 minutes before curing||whitish seam||from 280 rubles.|
|Polymer M-1 PVA (carpenter)||Bank 0.5 kg||10 minutes before curing||white seam||from 200 rubles.|
How to disassemble for repair
Now, when we figured out how to build the facade with MDF profile, left to learn how to dismantle the frame of the facade of laminated MDF. frame disassembly problem with filling is that the product is not only firmly glued, but in addition is connected wooden shkantami.
disassembly procedure is as follows:
- Overturn facade facing downwards;
- We select the screw about 2 times thinner connecting dowels;
- A dowel screw is screwed a few turns;
Grip the pliers head
- Hold the head of the screw with pliers take out the dowel;
We take out the dowel
- We perform the same operation on all corner joints;
- Overturn the front face up and making little effort to dismantle the frame apart.
When frame reassembly using new dowels and thus update the adhesive layer.
Production of MDF Profile
MDF (fibreboard fine fraction) - a slab material with a smooth surface without any relief. As of rectangular pieces with a straight face to make the profile with difficult terrain?
Position the cutter when processing the workpiece
It turns out that the production of relief profile is not a big deal, if there is a special milling equipment at your disposal. The relief on the surface of the bar with a rectangular shape is applied to the cutter. Form of relief is dependent on the configuration of the cutter.
If you decide to link their activities with the manufacture of furniture facades, except for the special machine, you have to buy a set of several mills.
So, you've read another article, published in the framework of the repair rate. Now you will be able to collect the furniture front, or at least make it out for repair.
