How to remove the chamfer on the oval hole. Facility removal and planing round and faceted blanks. Methods cutting edges

Easy in the manufacture of a device for removing the champers on wooden bars and non-rigging boards, as well as for planing and other types of processing round or faceted wooden blanks.

When planing of wooden bars and non-bourgeing boards, it almost always happens to take small chamfer from the ribs to brute them to one degree or another. However, for this you have to keep the shutter obliquely, approximately at an angle of 45 degrees, which is not always convenient, especially when working with electronics.

From this position, you can go out if you make a special device in the form of a long longitudinal corner, into which the processed bar was laid and thus the edge from which you need to remove the chamfer.

In addition, such a device could be used for planing faceted and round wooden blanks (for example, handles for garden tools: shovel, forks, robel, etc.), which are very uncomfortable to strict on a flat surface.

I thought about the manufacture of such a device, just when the harvest of the workpiece for the handles of the shovel (see my article ""), because with a similar adaptation, I would go much easier and faster.

As a result, I decided to make this fixture, for which I needed the following accessories:

Materials and fasteners:
Two wooden strips with a thickness of 2 cm, 4 cm wide, and 6 cm, and 2 m long.
Wooden Planck 2 cm thick, a width of 5 cm, and a length of 50 cm.
Screws on a tree 4x50 mm.

Instruments:
Drawing and measurement tool (pencil, roulette and square).
Awl.
Electrolovka with a filling for curly cut.
Electrofer-screwdriver.
Metal drill with a diameter of 4 mm.
Spherical cutter on wood.
Screwdriver pH2, for wrapping screws.
Sandpaper.

Operating procedure

First, we place a strip of 6 cm wide, and drills along its entire length, with one side of 5 or 6 holes for screws.

On the opposite side of the plank, we divorce these holes under the head of the screws using a spherical cutter on a tree.

Then we insert the screws into these holes and attach our bar to the end of another 4 cm wide strip.

As a result, we get such wooden corner 2 m long.

After that, with the help of an electric bike, drink such a workpiece from the short strip.

It will serve as a stopper for placed billets, and at the same time, supporting our fixture.
We also place this workpiece and drill three holes under the screws.

And then screws, screw this workpiece to the end of our device-corner.

From the remaining piece of the plank, they drink two more billets with the electric lobby.

We will commit them to the back of our device, where they will serve additional supports.

In the same rear of the device, we drill on each side two holes for the screws.

The tops of these holes are also divorced by a spherical cutter on the tree in order to drown the heads of the screws.

Now they bring our blanks with screws.

All elements of fixtures and especially ends, process sandpaper.

And here is our fixture!
This looks like his back.

And so the front part.

Now on this device you can handle bars.
For example, I laid a block-blank for the shovel knob into this adaptation - rear view.

And this is a front view.

But the bar is not square, but a rectangular in cross section. Now and from such bars will be easy to remove the chamfer.

But I put it in the device, round in section a purchase handle for the shovel.

Such round blanks will now also be very convenient to handle in this device. Moreover, they can not only be strict, but also carry out other types of processing, for example, drill holes in them or saw.

Well, on this, perhaps, everything! All so far and convenient in the work of devices!

In technological, ergonomic, and more often in the aesthetic purposes for processing the edges of products use the chamfer. Anyone in his life more than once heard this short word, often not knowing his meanings. So, the chamfer is what it is and where can I find it? How important is this item?

FAQ - What is it?

First of all, it is the edge of the corner of the material. Apply it for technological purposes in mechanical engineering and metalworking to improve the quality of the weld. In the same area, you can meet the fastening hole, which serves to reduce the probability of injury by sharp edges. The same way of preparing holes can be seen in the production of furniture, only in this case it serves to fasten the details of it (when bolt and screw caps are not visible).

For aesthetic purposes, a chamfer is used and when flooring. Due to this method of processing the edges of the slit, which are formed when the temperature and humidity drops are not noticeable.

Fastening holes

As mentioned above, the chamfer is used to process mounting holes. It serves, first of all, to reduce the danger of injury by sharp edges of the hole, but it is also used for fastening the parts in the latitude. This treatment is distinguished only by the corner of the material of the material. If the angle is usually selected 45 degrees, then the recommended slope of the bevel on the hole and the shaft is 10 degrees.

Welds

Experienced specialists will say that when performing the chamfer. That it will not only provide high quality Connections, but also many times will facilitate their work.

When connecting two sheets, the chamfer was used to bypass the restriction on the depth depth of the weld. Structurally, this element can be made in two ways: with a straight and curvilinear surface. At the same time, the second method is more often used, since this recess has a greater volume.

Wooden floors

When flooring wooden boards It is necessary to consider many nuances. This is the quality of the material, and the degree of its drying, and the conditions under which the surface will be operated. If with two first questions you can easily decide in advance, then the conditions of the floor can not always be predicted reliably. In this case, the chamfer is applied. What it is - explained above. It will not only make it possible to look more neatly and beautiful, but also help to avoid visible slots between the boards, which will definitely appear over time.

When working with an array of wood, a question may arise: "How to make a chamfer?" Especially since the woodworking machine is not quite suitable for this. First of all, the material is grinding well (it will be impossible to do it later). For chamfer removal use with edge cutter On the bearing. This allows you to achieve the perfect quality of the treated surface, even with a small curvature of the boards.

Laminate

Today, not everyone can afford the floors from the wood massif and parquet Board in view of large labor and loss of time repair work. In the floors in the apartments, you can find a laminate in the apartments. It not only simply and quickly stands, but also has excellent operational and aesthetic qualities, in many respects, not yielding natural surfaces.

Currently, the market is more often buying laminate, on the edge of which there is a chamfer. What is it and how affects the end result? First of all, it looks more representative, completely repeating the appearance natural tree. Secondly, this minor nuance masks changes in gaps between the boards, which appear during the operation of the floor.

Many consumers are still skeptical about such outdoor coating. It is argued by the fact that the unacceptable chamfer in the laminate, which will allow dust and dirt to accumulate in recesses and penetrate the inside of the seams. It's not so because modern technologies Materials make it possible to make laminate water and dirty over the entire surface. A high-quality castle will prevent the penetration of garbage in the seams.

Remove the chamfer from the board different ways. Two of them are most common: with manual and by automatic tool. Negative side Applications hand tool (various ruled) is considered a high degree of trauma, as well as a catastrophically low pace of work. Of course, the automatic and semi-automatic milling mills are perfectly suitable for solving the targets.

On the site http://www.zaoportal.ru/product/view/111 you can purchase a professional chamfering machine. The main reasonIn which homemade masters avoid purchasing such equipment, the apparent complexity is considered. In fact, the setting and use of direct assignment does not cause any difficulty at a novice user.

It is initially important to choose the appropriate type of cutter. There are several types of facets. Select the one that is suitable for solving your particular task. Not always a suitable milling cutter is in a set with a mill.

But it will not be made of great work. The cutters of this kind are in the stores of tools in free access and stand a penny.

The preparation of the milling driver is as follows:

• the hose from the vacuum cleaner is placed in the waste disposal nest;
• setting the position of the cutter;
• the milling mill is fixed by the specified position;
• horizontal guides are installed.

With a supplement in the form of a vacuum cleaner, it is much easier to work. When processing a tree, there are almost no waste.

Initially, the height adjustment head of the cutter must be rotated to a characteristic click. The depth regulator is pulled by 3 mm down. Next it goes on the head. Thus, we get a "zero" position of the cutter.

Now, rotating the height adjustment head, you can quickly and without much difficulty changing the position of the cutter by 5, 10 mm.

Guide milling mills for the correct chamfer should also be configured. It is achieved quite simple - it is important only to spin the nuts on the guides to the state when the mill will slide along the surface being processed, as on the rails.

The chamfer is a specially obtained edge on the end surface of the metal product or on the tube wall, bevelled at a certain angle.

main destination - Preparation of metal to further welding work.

Why do you need to remove the chamfer?

Processing of sheet ends or pipe walls allows:

• Get the perfect provider and reliable connection Welding seams
• Reduce the time of welding
• Prevent cases of injury to employees about sharp corners of the product
• Simplify the further installation of the erected metal design
• Do not manually grind the edges of the edge of the sheet or pipe

If you do not perform chamfering, then in products, the thickness of which exceeds 5 mm, with time there may be a welding seam and the design will lose strength.

The angle of the chamfer

The chamfering angle from the edge of the sheet or pipe is selected, based on constructive features Products or tasks for welding. As a rule, the standard chamfering angle for the metal sheet profile is 45 °, for pipes - 37.5 °.

Types of beam

You can cut the edge with metal rolled products in three ways, namely: Y-shaped, x-shaped and J-shaped (another name - "glass" chamfer).

Also, in the technical literature you can meet another letter notation: V, K and U, respectively. The most common way to remove the edge in production is the Y-shaped method and X-shaped. When the welding seam is required (for example, on products complex design), I use a chamfer with a curvilinear surface. The chamfer removal method is J-shaped, performed using special automatic frequency. This method allows you to create a larger welding bath than other ways.

Other types of edge cutting (butt type of compound with a broken edge) are not so often used.

Features of the chamfer removal

If it is required to perform cutting edges on a metal product, then special units are used - the trimming agents differing from the cutting method into three types (air-fiery, mechanical and gas particle equipment).

The process of cutting occurs as follows: With the help of the clamps, the fake excavator is attached to the edge of the sheet or the inner side metal pipe. Next, the desired sharpening angle is set. When the machine is turned on, the cutting head is supplied to the product and the chamfer cutting process occurs. After the end of operation, the cutter returns to its original position. After cutting the chamfers, working surface Products are considered prepared for further welding work.

During the slicing chamfer, the so-called welding capacity (bath) is formed, in which a hot welding composition is assembled. It should be understood that the edge with the chamfer has a certain point, which is usually 3-5 mm. At the time of filling the tank with the welding composition, the dull section is properly adjusted. Due to this, the desired seamlessness of the seam is achieved and additional reliability is created.

Methods cutting edges

Currently, the production uses two methods for removing the edge: thermal and mechanical.

The mechanical chamfer is considered to be the highest quality, since this method is performed on special equipment - Fathecking machines, milling machines, edge-savings and other devices. Benefits this method Consist in the following:

• After the chamfer removal, the product retains its structure and does not lose physico-chemical properties
• Mechanical method provides high tightness and reliability of future welding seams
• Saving time.

Mechanical Same Removal Method It is a kind of guarantor of the quality of metal products processing before welding work. The only "minus" this method It is the high cost of aggregates and labor-intensity of work.

The thermal method is the chamfer of air-plasma and gas flame chamfer (using the Orbit unit). The air-plasma edge cutting allows you to get the appearance of the chamfer close to the factory (or mechanical chamfer). However, it requires an ideally smooth leaf surface or pipes at a certain angle. In many industries, this kind of face cutting is the main due to the cost-effectiveness and high speed processing. Performed on special plasma equipment.

The gas-plasma cutting of the Fabin requires special conditions of implementation and therefore is characterized by a low cost. However, the quality of the resulting cutting is much lower than when mechanical method or air-fiery. In addition, in most cases, such a cutting chamfer requires additional mechanical processing. Basically, this method is used for handicraft treatment of ex-pipes. In addition, using the thermal method of cutting chamfer (gas-plasma and air-plasma chamfering), in a metal product due to overheating, a plot with modified physical and chemical properties (thermal zone). This negatively affects the tightness and reliability of future welding seams and the strength of the structure itself.

Thus, the mechanical lighting of the chamfer is a more preferred method of processing the edge of metal rolled products, since it allows you to preserve the properties of the product and does not affect the quality of future welding.
