What is burr and what does burr mean?

"burr", also known as "noise" in **. It is a small ** trend that appears on the **** chart in the opposite direction of the original general trend, and it is often difficult to distinguish whether it is a reversal (often a deception line).

Thorn name. One of the nine thorns. "Lingshu Official Needle": "The burr, the thorn is paralyzed." That is, the method of superficial puncture **** surface paralysis, and the commonly used ** acupuncture method is developed from this.

When one of the pair's points breaks through the trend line, and all other highs are normatively located on the trend line, we call this breakout the phenomenon of "glitches".

When the pair encounters resistance at the first trend line, it can partially close its position, move above the first resistance level to the second line, and close all positions before the second trend line.

When the pair pulls back, it buys ** above the first trend line, and then sells high and buys low in the range of the first and second trend lines. Chemical deburring.

Chemical deburring is the use of chemical energy for processing, chemical ions will adhere to the surface of the part, forming a film with high resistance and low conductivity to protect the workpiece from corrosion, and the burr can be removed by chemical action because it is higher than the surface. This deburring method is widely used in pneumatic, hydraulic, construction machinery and other fields.

02 High temperature deburring.

First, the parts that need to be deburred are put into a tight sealing chamber, and then the whole is sent into a hydrogen and oxygen mixture gas with a certain pressure, and the mixture gas is ignited to release heat, and the burrs of the parts will be burned off without hurting the parts.

03 Tumbling and deburring.

The part is placed in an enclosed drum along with the abrasive, and as the drum rotates, the dynamic torque sensor, the part and the abrasive work together to produce grinding and deburring. Abrasives can be quartz sand, wood chips, alumina, ceramics and metal rings.

04 Hand deburring.

This method is more traditional and the most time-consuming and labor-intensive. It is mainly polished by manual use of steel files, sandpaper, grinding heads and other tools. The most commonly used in production now are trimming knives.

The burr is white, that is, the smoothness of the cutting or cross-section of the object, and the palm touches the back of the object.

It's the excess material at the edges.

A burr is a tiny spine that is particularly small.

Meaning: Poor, unkind. It can be said that people can also refer to things.

From: The dialects of the northeastern and western regions of Shandong, Texans use more words, and they are also used in other places.

Example sentence: You are really prickly, who will play with you if you continue like this.

Stunging bristles are a kind of connecting material commonly used on clothes, which is divided into two sides, one side is fine and soft fibers, and the other side is a harder thing like a small hair scratch. Grows on the head, legs and tail of sheep. In the area of Jiang Yueqing, a wild berry is called "thorn hair", that is, raspberry.

Thorn hair is a commonly used connecting material on clothes, divided into male and female sides, one side is fine and soft fibers, and the other side is hard like a small hair scratch. There are two sides, one with a hook and the other with a loop. The general clothes are hooked on it.

It is very common in our daily life, and it is generally used in mobile phone bags, pockets, and two pieces of things that will stick together.

Thorn hair [cimao (ci - read the first tone)], a dialect in the northwestern and western parts of Shandong, Texans use more words, and they are also used in other places.

Explanation: Similar to bad, not kind, you can say people, you can also refer to the example sentence: You are really prickly, who will play with you if you continue like this.

Stinger hair is a short, coarse fiber that grows on the head, legs, and tail of sheep.

In Yueqing, Zhejiang, a wild berry is called "thorn hair", that is, raspberry.

Dialect, caterpillar with thorny kind.

Burr, metal casting, milling, refers to the appearance of residual chips and very fine microscopic metal particles on the surface of metal parts. The more burrs, the lower their quality standards.

<> the untidy orifice on the ** is the burr, and deburring is to remove the burr with knives and tools. In the picture below, the burr is cut on the right, and the burr is removed on the left.

Principle: Dry ice blasting medium Dry ice particles are accelerated in a high-pressure air stream, ejected through a nozzle, and impact the working surface. The temperature of the dry ice particles themselves is extremely low (-78) and directly sublimates from the solid state to the gaseous state at atmospheric pressure, absorbing a large amount of heat, resulting in a very low temperature and increased brittleness of the surface to be cleaned, and the dry ice particles can stain the surface.

In machining, the edges, corners, edges and other parts of the workpiece will inevitably produce burrs of different sizes after cutting. The presence of burrs will have a negative impact on many aspects such as machining accuracy, assembly accuracy, reprocessing positioning and appearance quality of the workpiece.

Deburring refers to the removal of fine metal particles from the surface of a workpiece, which are known as burrs. They are formed during cutting, grinding, milling, and other similar cutting operations.

Deburring can be done using a suitable deburring machine.

4. Stinging hair is a short, coarse and stiff fiber that grows on the head, legs and tail of sheep.

5. In Yueqing, Zhejiang, a wild berry is called "prickly hair", that is, raspberry.

Although the burr is not a small thing, it directly affects the quality of the product. Therefore, with the attention of various industries to burr removal, deburring methods are also emerging. There are several commonly used trimming deburring:

Handmade, traditional; Trimming knives gradually replace these traditional methods, which do not require technical treatment, save costs and are environmentally friendly. Chemistry, based on the principle of electrochemical reactions, automatically and selectively completes the deburring operation of parts made of metal materials. It can be widely used in the deburring processing of pump bodies, valve bodies, connecting rods, plunger needle valve couples and other parts made of different metal materials in pneumatic, hydraulic, construction machinery, nozzle oil pumps, automobiles, engines and other industries.

Suitable for internal burrs, heat-treated, and finished parts that are difficult to remove. Electrolysis, the use of electrolysis to remove metal parts....

Burr is a term for metal casting, milling, and plating, which refers to the appearance of residual chips and very fine microscopic metal particles on the surface of metal parts. The more burrs, the lower their quality standards. Burrs are one of the surface defects of steel, which is manifested as uneven flash at the end of the steel cut by cold cutting, hot sawing or flame cutting, and extruded excess metal at the weld when the pipe is welded.

The thickness of the burr at the end of a cold-cut product depends on the gap between the cutting edges. General products allow a certain height of burrs; However, the internal and external burrs of the welded pipe must be scraped off. <
