Metal deburring tool

Deburring tool NB1100

Good day to you all. In my last review where I dealt with the deburring tool I wrote: after receiving the set “file all parts”. And then I remembered from the analogy with the commercial: “where was? beer drinking ah. and men probably do not know” because “they do not clean guns abroad with bricks”, and for this purpose there is a special tool called “gratosnimiter” (“grat”. from German word “grat”. excess metal, remaining on the edges of products after any process or treatment). But abroad of course it has a different name, more often it is called “Deburring tool“. Anybody who is interested, please follow this link. A bit of history. Many Soviet designers in the instruction had a footnote that details before assembly should be “processed with a file”, and subsequently from it even the national meme and set of jokes on this subject was born. But it certainly can not last forever because it is not convenient and productive, because this is the 21st century. Over time a whole class of tools was invented for this purpose. “Deburring Tools”. and all we have to do is to use them. A little bit about the product itself. Of course it is not branded Kraftool, Rothenberger or RUKO for example. NB1100. a typical representative of the Chinese-style, it does not have anything outstanding, but it works well, and the price is not expensive in contrast to the branded. Except NB1100 on aliexpress most frequently there are two more models: EO2000. in the form of a pen: But as for me “in the Chinese version” of similar form factor is too flimsy, I saw similar cases at Milwaukee, but I never held them in hands, and those that fall into my hands at work had a body of aluminum. In addition to the above mentioned two very often seen in Ali and NG1000, but I did not buy it. at home occasionally “pokrjabat” dural enough and NB1100, and at work in the pantry issued a brand. Purpose Like many Deburring Tools, the NB1100 is designed for deburring and chamfering various profile surfaces and for internal and external deburring of copper, plastic, aluminum, and steel pipes as well as for chamfering straight edges, keyways, etc.п. Thanks to replaceable blades, no need to resharpen or fully replace the tool when it wears out. It is possible to process materials such as steel, aluminum, plastic, copper, brass, cast iron. For this purpose you can find and buy on aliexpress a lot of interchangeable blades of different types. Here is for example one of the simplest most common blades: When buying blades of course need to look at what materials they are designed to handle, so as not to try to remove burr from steel blade designed to handle plastic. For this purpose, sellers who sell them usually have signs like this: Here are some of the stores where you can buy replacement blades: https://aliexpress.ru/item/item/1005001626270980.html https://aliexpress.ru/item/item/1000004810988.html https://aliexpress.ru/item/item/33023695930.html https://aliexpress.ru/item/item/32800040127.html In addition to the simplest blades are often found and highly specialized, for example for machining holes. Their appearance is similar to countersinks: And also in the form of “funnel”. it is convenient to remove burr from the outer side of pipes and rods: The class of “Deburring Tools” does not end here, of course, but today we have basically only a review of Deburring Tools NB1100, so this information was just a context as additional attachments. Of course, further in the text should have shown a lot of photos from which would have been little understandable, and even less visible (any metal tends to shine and give a glare), so I think it is uninformative and will confine myself to one photo “was / is”. On a more informative note, you can check out the professionally produced videos on “Deburring Tools”:

Note: of course the video is slowed down, in real life, they do it quickly and without looking. Most often sit on a chair and chat with the person (looking more at him than at the part), rather than “savor” this process t.е. Everything is done by feel and checked with a “finger gauge.”. Warnings: When buying other (less widespread) models of gravity pullers at aliexpress be careful not to go like this: Of course “should”, but where were his eyes when he bought the product with a collet?

And the traditional: and what a hamster said? Khoma flatly refused to participate in the photo shoot with the tools from the last century and ran away: He must have mistaken them for instruments of the Medieval Inquisition and thought they wanted to skin him alive. By the way, modern tools for deburring Homa didn’t scare even a little bit:)) By the way, kits of jigsaws from the USSR don’t scare Homa either. So, it’s up to you to choose between these tools: And we have finished our business with Homa and washed our hands until the next review. Beaver to all and good luck with your needlework.

Edging, chamfering

Edging (chamfering) is a technological operation to prepare the surface of the material for welding. The quality of this procedure directly affects the reliability and durability of the welded structure, e.g. bridge abutments. No one likes to see bridges collapse.

To choose the right edge cutter you need to have a clear idea of whether you want to machine a sheet metal, a pipe or a complex geometry, or both.

Automatic chamfer cutters are suitable for companies where edging is performed regularly and in large quantities. Their basic material is long straight sheets (UZ-50) and short flat parts (SBM-500). Some automatic edgers also allow you to process pipes. See an example of sheet metal processing with the automatic edger.

Samples of chamfering with automatic edgers

Manual chamfering machines are used when maximum flexibility is required of the equipment, and the chamfer width does not exceed 22 mm. With their help it is possible to process curved surfaces, round off an edge for painting, make countersinking of holes, process pipe ends and many other things. As a rule, customers prefer manual machines because of their low cost, compactness, multifunctionality and high reliability (there is nothing to break here).

Besides the differences in the types of tasks performed modern pipe end bevelers are distinguished by machining methods.

Special solid cutters are used in edge-splitting machines, and in edge-splitting machines milling heads with carbide plates are used. End face bevelers and pipe cutters use cutters with specific angles and patterns. As you can see, the range of equipment and consumables for it is quite wide. All of these items can be found on our website under accessories for edgers and if you don’t find something or have a question you can always call us for advice.

DEVICES FOR CHAMFERING BARS/BOLTS/ STUDS

The chamfering device is a convenient and productive counterpart of the chamfering cutter and is designed mainly for use on universal machines.

The chamfering machine is a convenient and productive counterpart to the chamfering cutter and is mainly intended for use on universal machines.

Note, that unlike other tools, the KOPAL unit needs to be purchased only once and then only needs to be replaced as the blades wear out!

The rugged chamfering unit housing holds the bevel guide cone and the blade is inserted.

The process of external chamfering looks like this:

-the device is placed over the workpiece and is automatically centered by the guide cone

-the cone shifts in contact with the workpiece and frees the blades of the blade

-eliminates any possibility of blade breakage as it would occur with another tool, such as an external chamfering countersink.

Chamfering knives are selected from a sufficient list for each type of material and processing and can be sharpened at different angles. selection is made by means of a clear and handy table.

The device is in fact a specialized attachment for external chamfering and facing. Can be used as a cutter to chamfer the bar.

When using the above devices as the working tool of specialized units, an ergonomic and lightweight machine for chamfering the bar is formed.

By the way, most machines for chamfering pipes are not suitable for the same operations on chamfering the rod, because they are fixed inside the cavity of the pipe. In case of the above described chamfering device this problem disappears.

The chamfering machine can have one, two or four working spindles and is a great alternative to expensive stationary bar chamfering equipment.

With the help of these machines it is convenient to organize a batch processing, for example, to chamfer bolts.

Types of chamfers

To cut an edge from rolled metal products can be done in three ways:

  • The Y method;
  • X-shaped;
  • J-shaped (another name for “shot” chamfer);
  • You can also find other designations in the technical literature: V, K, and U bevel.
  • The most common method of beveling in production is the Y-bevel method and the X-bevel method.
  • For high-precision welds (e.g., on products of complex construction) a chamfer with a curved surface is used.
  • J chamfering is performed by special automatic chamfering machines. This process creates a larger weld pool than other processes.

(butt type joint with a broken edge) is not often used in factories.

Chamfering machines

Parts that are to be welded must be pretreated. It is performed in order to prepare the edges for subsequent joining. Proper pretreatment is essential for strength and durability of the weld. To be able to meet the requirements of technical standards, it is better to use a chamfering machine. It bevels at a given angle with a given width, and rounds off the edges and prepares the pipe for subsequent welding.
